Bob Pettit scored 50 points in Game 6 of the 1958 NBA Finals, 19 of his team's last 21, and the St. Louis Hawks beat the Boston Celtics 110-109 to win the championship. He did it from the spot that basketball now calls the 4. The power forward is the bigger of a team's two forwards: a rebounder and interior defender who sets screens, finishes close to the basket and, in the modern NBA, is expected to shoot from behind the three-point line as well.
That description holds at every level of the American game that uses the five traditional positions, from high school through the NCAA, the WNBA and the NBA. No rulebook contains it. The NBA's official rules say a team is five players and leave the arrangement to the coach, so "power forward" is a job description that coaches wrote and have kept rewriting. The player who fills it is the second big man in the lineup, positioned between the center, who stays nearest the rim, and the wings, who play outside. How that middle position moved from the low block to the three-point arc is the subject of this page.
What a power forward does: the job of the 4 at both ends
Start near the basket and work outward. The center stands closest to the rim. The power forward is the next player out, the second of a lineup's two big men and the larger of its two forwards. For most of the sport's history that meant a man of about 6-foot-9 who lived within fifteen feet of the hoop. He rebounded. He set screens. He guarded the other team's strongest forward, scored on whatever the offense left near the basket, and took on enough of the physical work that the center did not have to do all of it.
Those duties are all still on the list. What has changed is how many more have been added to it. An NBA power forward is now asked to do most of the following, in proportions that depend on the team around him.
| Phase of play | What the 4 is asked to do |
|---|---|
| Half-court offense | Set ball screens and handoffs, then roll, pop or space to the arc |
| Scoring | Finish at the rim, post up a smaller defender, shoot the open three |
| Offensive glass | Crash from the weak side when a teammate's shot goes up |
| Half-court defense | Guard the opposing forward and help at the rim from the far side |
| Defensive glass | Box out and secure the rebound that ends the possession |
| Transition | Run the middle lane to the rim, or trail the play to the top of the arc |
Two things about that table. First, almost none of it involves holding the ball for long. A point guard may dribble for most of a possession; a power forward often touches the ball for a second or two, as a screener, a finisher or the man who moves it along to the next shooter. The position is defined by what happens away from the ball, which is why box scores have always flattered some 4s and undersold others.
Second, the job sits on a hinge. The 4 has to be big enough to belong with the center and mobile enough to belong with the wings, and which way a particular player leans tells you a good deal about the team he plays for.
The WNBA and college basketball use the same five positions, and the power forward's work is the same in outline. The differences are geometric. The NBA's three-point line runs 23 feet 9 inches from the basket above the break and 22 feet in the corners, and its lane is 16 feet wide. The NCAA and the WNBA use a shorter line, 22 feet 1¾ inches at the top, and the college lane is 12 feet across. A college 4 plays in a more crowded middle and shoots a shorter three. This page describes the NBA version unless it says otherwise, and our guide to all five positions and how they fit together covers the wider arrangement.
The traditional 4: back to the basket, shoulder into the defender
Picture the Utah Jazz of the mid-1990s. Karl Malone runs to the left block, turns, sticks out a hand the size of a catcher's mitt and takes an entry pass with a defender leaning on his hip. One dribble toward the middle, a shoulder into the chest, a short shot off the glass. If the defense sent a second man, the ball went back out. If it did not, Malone scored or went to the foul line, and he went to the foul line more than almost anyone who has played.
That was the traditional power forward's offense, and it had three parts.
Scoring with his back to the basket. The 4 took position on the low block, eight feet or so from the rim, and worked from there with a drop step, a short hook or a turnaround jump shot. Elvin Hayes built a Hall of Fame career on one move, a turnaround from the baseline side that defenders knew was coming and could not reach. The techniques belong to a craft of their own, laid out in our guide to low-post moves and how to defend them.
Offensive rebounding. When a guard missed, the 4 was already under the basket with inside position. Many of his points came from second chances and many of his team's possessions were extended by them.
The mid-range jumper as a release valve. The best of the old 4s could step out to fifteen or seventeen feet and make an open shot, which punished a defender who sagged into the lane. Malone's jumper from the elbow, fed by John Stockton, was among the most reliable plays in the league for more than a decade.
Why the rules of the time rewarded it
Until the 2001-02 season the NBA prohibited zone defense. Under the "illegal defense" guidelines a defender had to stay near his own man or commit fully to a double team, and could not hover in between. That made the post-up efficient: an offense could clear one side of the floor, throw the ball to its power forward and know that help had to come from far away and in plain view.
On defense the traditional 4 was the team's second line of muscle. Maurice Lucas of the 1977 champion Portland Trail Blazers was called "The Enforcer," and the nickname described a real function: he guarded the opponent's most physical scorer, set screens that hurt and made driving into the lane an unpleasant idea. Charles Oakley did the same work for the New York Knicks in the 1990s beside Patrick Ewing.
What nobody asked for was range. The three-point line arrived in the NBA in 1979-80 and for two decades most power forwards treated it as a boundary. Tim Duncan went entire seasons without making a three-pointer and nobody in San Antonio minded.
The modern power forward: spacing, closeouts and the short roll
The change can be stated as a single instruction. The old 4 was told to get as close to the basket as he could. The new one is frequently told to stand as far from it as the court allows.
Spacing is the reason. A power forward stationed in the corner or on the wing, behind the arc, takes his defender with him. That defender is usually one of the opponent's two biggest players, so moving him 23 feet from the basket empties the lane for a guard to drive into. If the big defender refuses to come out, the 4 has an open three. If he comes out, there is nobody behind him. The offense gets something either way, and it gets it without the power forward touching the ball.
Standing still is only the first requirement. The second is attacking a closeout. When a defender who has been helping in the lane sprints back out to a shooter, he arrives off balance and moving forward, and a 4 who can put the ball on the floor for one or two dribbles will go straight past him. From there the play is a layup, a kick-out to the next open shooter or a short pass to the center at the rim. A power forward who can only catch and shoot is useful. One who can catch, drive and make that next pass is a starter.
The short roll and the four-on-three
The third skill is the one that separates the best modern 4s from the rest. Defenses facing a great ball handler often send two men at him as he comes off a screen. The screener, left alone, rolls only as far as the foul line, catches the pass in the middle of the floor and finds himself with the ball, three teammates and only three defenders between them and the basket.
What he does in the next second decides the possession. Draymond Green made a career of it for the Golden State Warriors, catching the pass that came out of the trap on Stephen Curry and choosing among a lob to the rim, a pass to the corner and a floater of his own. Chris Webber did a version of it a decade earlier in Sacramento, where the offense ran through the power forward and the center at the elbows and both were expected to pass like guards.
Add one more item. A modern 4 who takes a defensive rebound is encouraged to keep it and dribble up the floor himself rather than hand it to a guard, because the seconds saved are worth more than the tidiness. Put all of this together and the judgment is hard to avoid: the modern power forward is a wing with a rebounder's responsibilities.
Screening duties: the pick and roll, the pick and pop and the dribble handoff
Most half-court possessions in the NBA begin with one player setting a screen for another, and the power forward sets a large share of them. The screen itself is simple. The decision that follows it is where the position earns its money.
- Set the screenThe 4 plants his feet beside the ball handler's defender and holds still until contact. Leaning or moving into the defender is an offensive foul.
- Read his own defenderHe checks whether the man guarding him has dropped back toward the rim, stepped up at the ball or switched onto the guard.
- RollAgainst a defender who steps up, he turns and dives to the basket for a pocket pass or a lob.
- PopAgainst a defender who drops back, he steps out behind the arc for a catch-and-shoot three.
- Short rollAgainst a trap on the ball handler, he stops near the foul line, catches and plays four against three.
- SlipAgainst a switch, he leaves a beat early and cuts to the rim before the defenders finish trading assignments.
The standard reads off a ball screen. Which one is right depends on how the screener's own defender plays it, and the choice is made in about a second.
The roll is the oldest answer and still the most dangerous near the rim. Stockton and Malone ran it for eighteen seasons in Utah, and the play survived every scouting report because the two of them read the defense the same way at the same moment. The mechanics of the action, and the coverages built to stop it, are taken apart in our explainer on how the pick and roll works.
The pop is the power forward's own contribution to the play. A center who rolls drags his defender toward the basket; a 4 who steps back to the three-point line drags his defender away from it, and a big man who has spent his career protecting the rim is rarely comfortable chasing a shooter out there. Dirk Nowitzki's Dallas teams built an offense around that discomfort. In the 2011 playoffs a small guard would come off Nowitzki's screen, two defenders would hesitate for half a second about who had whom, and the ball would find a seven-footer with an open jumper.
The handoff, and the screen that is not allowed
The dribble handoff is the same idea with the roles reversed. The 4 holds the ball near the elbow or the top of the arc, a guard runs toward him, and the big man hands it over while his body acts as the screen. If the defender cheats over the top to deny the handoff, the 4 keeps the ball and drives the space the defender just left.
All of it depends on the screen being legal. The screener must be set before contact, must give a moving defender room to stop, and may not extend a hip, a knee or an elbow into the man going by. Officials call the moving screen unevenly, and power forwards who set dozens of picks a night learn exactly how much each crew will allow. The standards are covered in our guide to what makes a pick illegal in the NBA.
Defensive duties: weak-side help, switches and the shooting big
A scouting report on a power forward's defense rarely starts with the man he guards. It starts with where he stands when the ball is on the other side of the floor.
That spot is the weak side, and the 4 who occupies it is usually what coaches call the low man. When a guard drives past his defender or a center rolls free to the rim, the low man is the one who leaves his own assignment, slides into the lane and meets the play at the basket. He has to get there early enough to matter and stay vertical enough not to foul. Then, if the ball is kicked out, he has to recover to a shooter who may be twenty feet away. It is the hardest help assignment on the floor, and our piece on how help rotations are supposed to work follows the chain of movements that begins when he goes.
The NBA limits how he can do it. A defender may not stay in the lane for more than three seconds unless he is actively guarding an opponent, so the low man cannot simply park under the rim and wait. He stands with one foot outside the paint, counting.
Switching onto guards
The second duty is newer. Many NBA defenses now switch ball screens: the two defenders involved trade assignments so that nobody has to fight through the pick. When a power forward's man sets the screen, the 4 ends up guarding a point guard on the perimeter with the shot clock running.
Whether he can survive there for five or six seconds is, for a lot of front offices, the first question asked about the position. Kevin Garnett could. At 6-foot-11 he moved his feet well enough to stay in front of guards and was long enough to bother the shot if they pulled up, which is much of why the 2007-08 Celtics, in his first season in Boston, were the best defensive team in the league and why he was voted Defensive Player of the Year. Dennis Rodman, four inches shorter, guarded every position during his career, from point guards to Shaquille O'Neal.
Guarding the opponent's shooter
The third duty is the mirror image of the modern offense. When the other team's power forward stands in the corner and shoots threes, somebody has to stand out there with him, and that somebody is no longer near the rim to help. Coaches choose between two bad options: leave the shooter and protect the paint, or stay home and trust the center to handle the rim alone. The tension in that choice is the reason the shooting big man became so valuable.
Rebounding: box outs, the weak-side glass and why 4s lead their teams
Coaches have taught for generations that a shot missed from one side of the floor tends to come off on the other. Nobody needs a tracking camera to see why. A ball that is long or flat keeps traveling in the direction it was going, hits the back of the rim and carries toward the far side of the lane.
The power forward is usually standing there. The center has often been pulled toward the ball to contest the shot or is locked up with the opposing center under the rim. The 4, on the weak side, is free to read the flight of the ball and go and get it. That geometry explains a pattern that runs through the league's record books: the team leader in rebounds has been the power forward about as often as the center.
Rodman's seven were consecutive, from 1991-92 through 1997-98, with three different teams. He was listed at 6-foot-7 and gave away height to nearly every man he boxed out. Barkley, listed at 6-foot-6, led the league in 1986-87 and through the 2024-25 season remained the shortest player to win a rebounding title. Neither fact makes sense if rebounding is about height. It is about position, timing and wanting the ball more than the next man.
The box out
The technique has not changed since the 1950s. When the shot goes up, the defender finds his man, makes contact with a forearm, pivots so that his back is against the opponent's chest and sits low with his arms wide. Done properly, it means the rebounder does not have to jump higher than anyone. He only has to keep the other player behind him until the ball comes down.
On the offensive glass the job is reversed: avoid the box out by moving before the defender can find you. An offensive rebound in the NBA resets the shot clock to 14 seconds, not the full 24, a rule in place since the 2018-19 season, so the second chance is a shorter one than it used to be.
Kevin Love's 2010-11 season in Minnesota is the modern reference point. He led the league in rebounding, and on November 12, 2010, against the Knicks, had 31 points and 31 rebounds in a game, the first 30-30 night in the NBA since 1982.
Size and build: how tall a power forward is and how the position slimmed down
There is no height requirement and never has been. There is a range, and it has moved.
For roughly forty years, the template was a player between 6-foot-8 and 6-foot-11 who weighed somewhere from 230 to 260 pounds. Shorter than the center, heavier than the small forward, strong through the shoulders and hips. Karl Malone, who lifted weights with a seriousness that was unusual when he entered the league in 1985, was the physical ideal: 6-foot-9, about 250 pounds, and fast enough to finish a fast break.
| Player | Listed height | NBA career |
|---|---|---|
| Bob Pettit | 6 ft 9 in | 1954 to 1965 |
| Elvin Hayes | 6 ft 9 in | 1968 to 1984 |
| Charles Barkley | 6 ft 6 in | 1984 to 2000 |
| Karl Malone | 6 ft 9 in | 1985 to 2004 |
| Dennis Rodman | 6 ft 7 in | 1986 to 2000 |
| Kevin Garnett | 6 ft 11 in | 1995 to 2016 |
| Tim Duncan | 6 ft 11 in | 1997 to 2016 |
| Dirk Nowitzki | 7 ft 0 in | 1998 to 2019 |
Read down the height column and the supposed standard looks loose even among the greats. Six inches separate Barkley from Nowitzki. What they shared was function, and the list is a reminder that a position is a job before it is a body type.
A caution about the numbers themselves. Listed heights in the NBA were, for decades, whatever a team's media guide said, often measured in sneakers and sometimes rounded generously in either direction. Before the 2019-20 season the league told teams to certify each player's height without shoes. Several well-known players shrank or grew by an inch on paper overnight. Any comparison across eras carries that asterisk.
Lighter, longer, quicker
The modern 4 is built differently. As offenses spread to the three-point line and defenses began switching, the 260-pound bruiser found himself guarding shooters on the perimeter and being attacked off the dribble. Teams responded by playing leaner forwards at the position, men of 6-foot-7 to 6-foot-10 with long arms who had grown up as wings.
Wingspan and standing reach now matter more to scouts than height. Draymond Green measured about 6-foot-6 in bare feet before Golden State drafted him 35th in 2012, with arms that measured longer than seven feet from fingertip to fingertip. That reach let him contest shots at the rim against players half a foot taller, and his speed let him guard the ones a foot shorter.
Power forward vs center: who protects the rim and who guards the perimeter
The two positions are both "bigs," they are often interchangeable on a depth chart, and many coaches no longer bother to distinguish them in conversation. On the floor the distinction is still there, and it shows most clearly on defense.
| Question | Power forward | Center |
|---|---|---|
| Where he usually defends | The weak side and the perimeter | The rim and the lane |
| Against a ball screen | More likely to switch or step out | More likely to drop back toward the basket |
| Help responsibility | Rotates in as the low man, then recovers out | Stays between the ball and the rim |
| Usual spot on offense | Corner, wing, elbow or the short roll | The rim, the baseline and the deep roll |
| Shooting range expected | Out to the three-point line | Varies; many still work inside |
| Who he guards | The opponent's forward or its shooting big | The opponent's biggest player |
The simplest test is to ask who guards the basket. Whichever big man stays home in front of the rim is functioning as the 5, whatever the roster says, and the other one is the 4. Our page on what the center does at both ends covers that half of the partnership.
How two-big lineups divide the work
When both players are traditional big men, the offense has to keep them out of each other's way. The standard answer is the high-low: one stands at the foul line, the other seals his defender near the basket, and the pass goes over the top. San Antonio ran it with Tim Duncan and David Robinson, a pairing known as the Twin Towers, and won championships in 1999 and 2003. The Los Angeles Lakers did something similar with Pau Gasol and Andrew Bynum on the way to titles in 2009 and 2010.
Duncan is the case that breaks the labels. The Spurs listed him as a power forward for his entire career. Beside Robinson, he was one. After Robinson retired in 2003, Duncan guarded the rim, anchored the defense and did nearly everything a center does for another thirteen seasons, and the listing never changed. Arguments about whether he is the greatest power forward ever or simply a great center are really arguments about whether to believe the roster or the film.
So a power forward can play center, and many of the best have. The cost is usually paid on the defensive glass and against the few opposing centers strong enough to punish a smaller man in the post.
Power forward vs small forward: why wings now play the 4
The small forward is a perimeter player. He handles the ball, scores from the wing and guards the opponent's best scorer out on the floor, a role described in our guide to the wing who plays the 3. For decades nobody confused the two forward spots. One banged and the other ran.
Then coaches started moving the 3 to the 4 on purpose.
Mike D'Antoni's Phoenix Suns of 2004-05 are the usual starting point. With Shawn Marion, a 6-foot-7 natural small forward, at power forward and Amar'e Stoudemire at center, Phoenix played faster than anyone in the league and won 62 games. The Miami Heat reached the same place by accident in the 2012 playoffs: Chris Bosh was injured against Indiana, LeBron James slid to the 4, and the lineup that resulted was so difficult to guard that Miami kept it and won the championship that June and the next.
What the small-ball 4 gives a team
The gains are easy to list. A wing at power forward can shoot, so the floor is spaced with four perimeter threats. He can dribble, so the offense can begin a play from any position. He can switch, so the defense does not have to choose between helping and recovering. And he is faster than the man assigned to guard him, which turns every missed shot at the other end into a possible fast break. The fuller accounting is in our analysis of what a small lineup really trades away.
What he gives up
Size, and everything that depends on it. A 6-foot-7 forward guarding a 6-foot-10 one can be posted up, shot over and moved off the glass. Opponents with a real power forward will go at the mismatch directly. Memphis did it for years with Zach Randolph, and Cleveland attacked Golden State's small lineups on the offensive boards with Tristan Thompson in the 2015 and 2016 Finals.
The honest summary is that the small-ball 4 wins the math and loses the wrestling match, and the outcome depends on which of the two the game turns into.
The stretch four: how the shooting big man changed what coaches want
"Stretch four" was once a specialist's label. It meant a power forward whose main skill was shooting threes, which stretched the defense out toward the arc and opened the middle. Coaches treated such players as a tactical variation, useful off the bench or against certain opponents.
A few moments turned the variation into the standard. In the 1995 playoffs Houston's Rudy Tomjanovich moved Robert Horry, a slender forward who had been playing on the wing, to the 4 beside Hakeem Olajuwon. Defenders who doubled Olajuwon in the post now had to leave a shooter to do it, and the Rockets won the title as a sixth seed. In 2009 Orlando reached the NBA Finals with Rashard Lewis, a career small forward, shooting threes from the power forward spot around Dwight Howard. In 2011-12 Ryan Anderson, Lewis's successor in that role, led the entire league in three-pointers made and was voted its Most Improved Player.
Nowitzki belongs in a category by himself. He was no specialist. He was a seven-footer who shot like a guard and was also his team's best player, its leading scorer and the man who took the last shot. His 2011 championship with Dallas ended the argument about whether a jump-shooting big man could be the centerpiece of a title team.
From specialty to requirement
The effect on the position was permanent. Once a few teams had a 4 who could shoot, the teams that did not were playing with a crowded lane against opponents with an open one. Within about a decade the question front offices asked about a power forward prospect changed from "can he rebound" to "can he shoot it," with rebounding assumed or done without.
There were casualties. Skilled low-post scorers who could not shoot from distance or defend on the perimeter saw their minutes cut, and a style of play that had filled arenas in the 1990s became a change of pace. Whether that was a loss is a matter of taste. As a matter of efficiency, the three-pointer won.
The full history of the role, the players who built it and the numbers behind it are on our page devoted to the shooting big man at the 4.
Why it is called a power forward and why coaches call it the 4
James Naismith's game had forwards, guards and a center, and for half a century the two forwards were just that: forwards, or "cornermen," interchangeable in name. The split came gradually as players got bigger and jobs got narrower. By the 1960s and 1970s coaches and writers were distinguishing a strong forward from a quick one, and "power forward" and "small forward" became the settled terms.
Nobody can identify the first person to say it, and claims to the contrary should be treated with caution. What can be said is why the word stuck. The position was the one that required force: rebounding in traffic, setting hard screens, defending the opponent's most physical scorer. Players such as Dave DeBusschere of the Knicks and Gus Johnson of the Baltimore Bullets were doing recognizably that job in the late 1960s, before the label was universal.
The irony is plain. The word "power" describes the position least well in the era when the term is most widely used. A modern 4 who weighs 225 pounds and takes most of his shots from 24 feet is a power forward only by inheritance.
The number
The 4 is a different kind of name. Coaches number the positions from 1 to 5, running from the point guard to the center, because digits are faster to draw on a whiteboard and survive a substitution. "Four" refers to the fourth of those slots and to nothing else. It is not a jersey number, and it has no connection to the numbers in a zone defense such as a 2-3, which count defenders in rows.
Announcers and coaches increasingly prefer the number to the name, and with reason. "He can play the 4" promises only that a player can fill the slot. "He is a power forward" still suggests a build and a style of play that the slot stopped demanding some time ago.
The players who defined the position, from Pettit to Nowitzki
Seven careers account for most of what the position has meant. They are listed in the order they entered the league.
| Player | Seasons | Team most identified with | What he added to the job |
|---|---|---|---|
| Bob Pettit | 1954-1965 | St. Louis Hawks | The first great scoring forward; first player to reach 20,000 points |
| Elvin Hayes | 1968-1984 | Washington Bullets | The turnaround jumper and extraordinary durability |
| Charles Barkley | 1984-2000 | Philadelphia 76ers, Phoenix Suns | Rebounding and scoring at 6-foot-6 |
| Karl Malone | 1985-2004 | Utah Jazz | The pick and roll as a foundation for an offense |
| Kevin Garnett | 1995-2016 | Minnesota Timberwolves, Boston Celtics | A 6-foot-11 defender who could guard anyone |
| Tim Duncan | 1997-2016 | San Antonio Spurs | Bank shots, rim protection and five championships |
| Dirk Nowitzki | 1998-2019 | Dallas Mavericks | The seven-foot shooter as a franchise player |
Pettit came out of LSU as a thin 6-foot-9 center and was moved to forward as a rookie because he was too light for the middle. He was the league's first Most Valuable Player, in 1956, won the award again in 1959, and made the All-Star team in every one of his eleven seasons.
Hayes arrived in 1968 as the first pick in the draft and led the league in scoring as a rookie, the last rookie to do so. He won a championship with Washington in 1978 and retired having played exactly 50,000 minutes.
Malone and Barkley were contemporaries and opposites. Malone was a machine of routine, eighteen seasons in Utah and 36,928 career points, a total that stood second on the all-time list when he retired. Barkley was improvisation: a forward listed at 6-foot-6 who took rebounds away from seven-footers and dribbled the length of the floor to dunk. Each won an MVP award in the 1990s and each lost in the Finals to Michael Jordan's Bulls.
Duncan has the strongest case as the best of them. San Antonio took him first in the 1997 draft out of Wake Forest, and he spent nineteen seasons there without a losing one.

- 5Championships
- 3Finals MVP awards
- 15All-NBA selections
Totals for 1997-98 through 2015-16, all with one franchise. All-NBA counts first, second and third team selections together.
Garnett went straight from Farragut Academy in Chicago to the NBA in 1995, the first player drafted out of high school in twenty years, and made the idea of a mobile seven-foot forward ordinary. Nowitzki, drafted ninth in 1998 and traded to Dallas that night, played 21 seasons for the Mavericks, the longest any player had spent with a single franchise through 2024-25, and in 2007 became the first European-born MVP.
Line the seven up and the direction of travel is obvious. Pettit and Hayes scored within fifteen feet. Malone stretched it to eighteen. Nowitzki made his living at twenty-four. The position followed the shot outward, and the players who came after him grew up assuming that was where a power forward stood. More on how the positions and the rules around them developed is collected on our basketball hub.
