Cricket Powerplay Rules Explained for ODI and T20

Cricket powerplay rules explained for ODI and T20 come down to one question asked before every single delivery: how many fielders are allowed to be standing outside the painted circle right now? Get the answer and you can read the state of a limited-overs match without the commentary. Everything else on this page — the geometry of the circle, the rain adjustments, the penalties, the English domestic variations — is detail hanging off that one count.

Here is the answer for both formats, in full, before anything else.

Format	Overs	Fielders permitted outside the circle
ODI	1–10	2
ODI	11–40	4
ODI	41–50	5
T20	1–6	2
T20	7–20	5

The bowler and the wicketkeeper are excluded from the count. So in the first ten overs of a fifty-over match, of the nine fielders who are neither bowling nor keeping, seven must be inside the ring and two may be outside it.

Why the restriction exists at all

It is worth stating plainly, because the name misleads people. A powerplay is not a bonus handed to the batting side. It is a restriction imposed on the fielding side, and it exists because limited-overs cricket without one is unwatchable.

Give a captain twenty overs and no constraint and the optimal strategy is to put every fielder on the rope, concede singles, and dare the batters to hit over the top. That is a legitimate way to win and a terrible way to sell a ticket. The circle forces a defined number of fielders to stand where the ball is most likely to go, which guarantees that boundaries are physically available for part of the innings. Every piece of white-ball strategy you have ever heard discussed — the platform, the acceleration, the finisher, wickets in hand — is downstream of that guarantee.

The circle itself

The marking is specified rather than approximate. Two semicircles of thirty yards radius, centred on the middle stump at each end of the pitch, joined by two straight lines running parallel to the pitch. Thirty yards is 27.43 metres. The result is an oval, not a circle, though nobody calls it that.

It is normally marked with white plastic discs rather than a continuous painted line, spaced a few yards apart, so that a ball running along the ground is not deflected by a ridge of paint. At most English county grounds you will see them as a ring of small white dots; at some, particularly for televised matches, a painted line is used and refreshed between fixtures.

Two smaller circles of fifteen yards are also marked at some grounds for close-catching purposes in certain competitions, but they are not part of the standard ODI or T20 powerplay count and are frequently absent.

What "outside the circle" actually means

This is the detail that trips up new supporters, and it is the reason the fielding side appears to break the rule constantly.

The count is taken at the instant the bowler delivers the ball. Where a fielder runs afterwards is entirely their own business. A fielder may stand with both feet inside the ring, set off as the bowler's arm comes over, and be twenty yards behind the line by the time the batter plays the shot. That is completely legal, and it happens on almost every ball in the closing overs of a T20 — backward point and mid-off sprinting outwards from the moment of release is a coached, deliberate manoeuvre, not a loophole nobody has noticed.

A fielder is inside the ring if they are within the marked area at that moment. A foot on the line counts as inside. The umpire at square leg has the primary responsibility for checking, and in televised cricket the third umpire will also be watching.

The penalty when the count is wrong

If more fielders are outside the circle than the phase permits at the moment of delivery, the umpire calls and signals no ball. That is not a warning or a technicality:

• One penalty run is added to the batting side's total.
• The delivery does not count towards the over, so it must be bowled again.
• In ODI and T20 cricket the next legal delivery is a free hit, on which the batter cannot be dismissed by most methods.

So a captain who miscounts in the nineteenth over of a T20 has just handed over a run, an extra ball, and a delivery on which the batter can swing without consequence. This is why you will see a fielding captain visibly counting his men with a raised hand before an over begins, and why the twelfth man will occasionally run on to point at somebody. It is not theatre.

Two further restrictions from the Laws apply in every format, including Test cricket, and carry the same no-ball penalty:

• No more than five fielders on the leg side at the moment of delivery.
• No more than two fielders behind square on the leg side.

The second is the surviving legislative memory of the Bodyline series, and it is why a captain setting a leg-side trap for a short-ball plan runs out of legal positions almost immediately. The names of the positions themselves are catalogued in the fielding positions guide.

The ODI blocks, in detail

Fifty overs split into three phases: ten, thirty, ten.

Overs 1 to 10 — two fielders out. Seven men in the ring, and the captain must choose two boundary positions from a dozen candidates. Conventionally that means somebody at fine leg and somebody at third, guarding the areas behind square where an edge or a glance runs away. Anything hit in front of square that beats the infield is four runs, which is precisely the point.

Overs 11 to 40 — four fielders out. Thirty overs, three fifths of the innings, under a single setting. Four out is enough protection for a spinner to attack while still guarding both straight boundaries and one square one, which is why this became the phase where spin does its work.

Overs 41 to 50 — five fielders out. Four men in the ring to save the single, five on the rope. The captain's problem inverts: not which two areas to cover, but which four gaps he can afford to leave.

The ODI structure has been rewritten repeatedly across the format's history. There have been eras with a mandatory opening block plus two discretionary five-over blocks, one of them chosen by the batting side — the "batting powerplay", which produced a strange stalemate where sides delayed it as long as the rules allowed and then lost wickets in it, and which was eventually scrapped. The number permitted in the middle band has moved between four and five in different periods, and each change moved par scores visibly. The table at the top of this page is the settled modern arrangement, and the practical consequences of it are covered on the ODI rules for beginners page.

The T20 structure, and the cliff at over six

Twenty overs, two phases, no middle band. Two fielders out for six overs, then five for the remaining fourteen.

The absence of an intermediate step is the defining feature of T20 as a game. In a fifty-over innings the transition out of the opening block is a step down. In a T20 it is a wall. An over that goes for eighteen in the sixth becomes an over that goes for seven in the seventh, bowled by the same bowler to the same batter at the same pace, purely because three men have walked to the rope.

Six overs is 30% of a T20 innings against 20% in an ODI, so proportionally the restriction is longer in the shorter format — one of the reasons T20 opening batters have strike rates that would be unsustainable across fifty overs. What that means for planning an innings is set out on the T20 rules for beginners page.

Rain: how the blocks shrink

When overs are lost, the powerplay blocks are recalculated so that each phase keeps roughly its share of a shortened innings — approximately 20%, 60% and 20% in a fifty-over game, and about 30% of the innings in a twenty-over one.

The published playing conditions contain a lookup table, and that table is the authority rather than the arithmetic, because the rounding does not always follow the obvious rule. Some worked figures from the fifty-over structure:

Innings length	First block	Middle block	Final block
50 overs	10	30	10
40 overs	8	24	8
32 overs	7	19	6
30 overs	6	18	6
25 overs	5	15	5
22 overs	5	13	4
20 overs	4	12	4

In the twenty-over game the same principle applies more simply: a full T20 has a six-over powerplay, a ten-over match has three, and a five-over match — the minimum for a result — has two.

Two mechanical points matter when an interruption lands mid-innings. First, if the reduction takes effect part-way through an over, the new restriction applies immediately; the umpire does not wait for the over to finish. Second, the two innings can end up with different block lengths if the second innings is cut further than the first, which is normal and not an error.

Revised totals are a separate question from revised fielding blocks. The target itself is recalculated by the Duckworth-Lewis-Stern method, explained in the DLS guide, and the English weather that makes all of this necessary is dealt with in rain, bad light and English playing conditions.

The over-rate penalty fielder

Most senior white-ball competitions now attach an in-match penalty to slow over rates. The mechanism: if the fielding side is not in position to begin its final over — or, in the fifty-over game, has fallen behind a defined checkpoint — one additional fielder must be brought inside the circle for the remaining overs.

So a captain entitled to five outside the ring at the death finds himself allowed only four. It is a far sharper deterrent than a post-match fine, because it costs runs immediately and in public, and it has done more to speed up limited-overs cricket than any amount of disciplinary paperwork. The exact trigger and the checkpoint timings differ between competitions and have been revised more than once, so check the conditions for the tournament in front of you.

English domestic variations

The powerplay you see on a Friday night at Old Trafford is not necessarily the one you saw in an international the week before.

Vitality Blast. The counties' T20 competition uses the standard six-over powerplay with two fielders permitted outside the ring, and the rest of the innings with five. The competition's structure and its own conditions are in the Blast format guide.

Metro Bank One Day Cup. The domestic fifty-over competition mirrors the international three-block structure, with the ECB's own reduced-overs table applied when the weather intervenes — the 32-over and 22-over rows above come from those conditions. Details are in the One Day Cup format guide and, for the play-offs, the knockout rules.

The Hundred. A different competition with a different rulebook. The innings is 100 balls rather than twenty overs, bowled in sets of five from the same end, and the powerplay is counted in balls, not overs — the first 25, with two fielders permitted outside the circle. If the numbers on screen do not match this page in July, that is why. See The Hundred explained.

Test and County Championship cricket. There is no circle and no powerplay at all. A captain may put every fielder on the boundary if he wishes, subject only to the two leg-side limits above. The reason the long form does not need the rule is covered on the Test cricket rules page.

Five things people get wrong

"The powerplay gives the batting side extra runs." No. It removes options from the fielding side. The runs are earned.

"That fielder was outside the circle, it should be a no ball." Only if he was outside it at the moment of delivery. Fielders retreating during the ball are legal and deliberate.

"There are eleven fielders to count." Nine. The bowler and the keeper are exempt.

"Batting powerplays still exist." They do not in international ODI or T20 cricket. Some franchise competitions have experimented with a discretionary extra block, but it is not part of the standard structure.

"Five men on the boundary means a defensive captain." In the last ten overs of an ODI, five is the maximum permitted. A captain with five out is not being negative; he is at the legal limit.

Common questions about powerplay rules

How many fielders are allowed outside the circle in a T20 powerplay?

Two, for the first six overs. From the seventh over onwards, five may be outside. The bowler and wicketkeeper never count.

How big is the 30-yard circle?

Thirty yards — 27.43 metres — measured from the middle stump at each end, forming two semicircles joined by parallel straight lines. It is usually marked with white discs rather than a painted line.

What happens if too many fielders are outside the circle?

The umpire calls no ball. The batting side gets a penalty run, the delivery is re-bowled, and in white-ball cricket the following delivery is a free hit.

Are powerplay overs the same in every competition?

No. ODI and T20 internationals and most domestic equivalents follow the tables above, but The Hundred counts its powerplay in balls, and franchise competitions occasionally trial variations. The playing conditions for the specific tournament are always the authority.

How do powerplays work in a rain-shortened match?

The blocks shrink to keep roughly the same proportions, using a lookup table in the playing conditions. A new restriction takes effect immediately, even mid-over.

Does Test cricket have a powerplay?

No. There is no fielding circle in the long form. The only field-setting limits are the maximum of five fielders on the leg side and two behind square on that side, which apply in all formats.

Where can I see the powerplay on a scorecard?

Phase splits are not printed on a standard card, but you can reconstruct them from the over-by-over run rate and fall of wickets — see how to read a cricket scorecard. The metrics analysts use for phase performance are defined in the cricket statistics glossary.

Cricket powerplay rules reward the spectator who counts. Before the bowler runs in, count the fielders beyond the ring: two tells you the innings is young, four says you are in the fifty-over middle, five says the restrictions have lifted and somebody is about to try something. For the tactical consequences across formats there is a companion piece on powerplays and the phases of an innings, and the wider England cricket hub covers the competitions these rules govern.
