Cricket Fielding Restrictions: Full Guide to Circle, Powerplay and Leg-Side Rules
A complete guide to cricket fielding restrictions — the 30-yard circle, powerplay limits, leg-side rules, fielding penalties, and how captains use these restrictions tactically.
Fielding restrictions are among the most important tactical elements in limited-overs cricket. They govern where fielders can stand, when boundary protection is allowed, and how many players can be positioned on the leg side. Captains who master fielding restrictions gain significant tactical advantages.
The 30-Yard Circle
The 30-yard (approximately 27.4 metre) fielding circle is a white oval marked on the pitch between the stumps and the boundary. During powerplay overs, no more than 2 fielders may stand outside this circle. During non-powerplay overs in T20s, up to 5 fielders may stand outside — meaning at least 5 must remain inside the circle (excluding keeper).
Powerplay Fielding Restrictions
| Format | Phase | Overs | Max Outside Circle |
|---|---|---|---|
| T20 | Powerplay | 1–6 | 2 fielders |
| T20 | After Powerplay | 7–20 | 5 fielders |
| ODI | Powerplay | 1–10 | 2 fielders |
| ODI | Middle overs | 11–40 | 4 fielders |
| ODI | Death overs | 41–50 | 4 fielders |
The Leg-Side Restriction
At no point in any format may more than 5 fielders (excluding the wicketkeeper) be positioned on the leg side. This law prevents captains from setting an entirely defensive leg-side trap — a tactic that would make scoring in that direction impossible and was used in the 'Bodyline' era to devastating effect.
What Happens If a Fielder Is in the Wrong Position?
If at the moment of delivery a fielder is in an illegal position — either outside the 30-yard circle when the powerplay requires them inside, or the team has more than 5 fielders on the leg side — the ball is called a no-ball. The batsman gets 1 extra run, and in T20 cricket the next delivery is a free hit.
The Two Inside Fielders During Powerplay
During a powerplay, while only 2 fielders can stand outside the circle, 2 of the remaining fielders must stand within a mandatory inner ring close to the bat. The exact inner ring in older ICC regulations has been simplified — the key constraint is simply that 2 fielders maximum are permitted outside the 30-yard circle. The keeper does not count toward the fielder restriction.
Tactical Uses of Fielding Restrictions
- Stacking the boundary in death overs: With 5 fielders allowed outside the circle in T20 overs 7–20, captains can place all 5 on the boundary to protect against sixes
- Aggressive powerplay field: With only 2 outside the circle, captains often set attacking slip cordons knowing batsmen will try to score through gaps
- Leg-side traps: 5 fielders on the leg side is the maximum — a leg-side heavy field is legal but leaving the off side completely open
- Midwicket/long-on split: Placing 2 boundary fielders on the leg side in the death allows good coverage without the full 5 on the boundary
Frequently asked questions
Does the wicketkeeper count as one of the restricted fielders?
No. The wicketkeeper is excluded from fielding restriction counts. The powerplay restriction of '2 outside the circle' refers to 2 of the 10 outfield fielders. The keeper can stand behind the stumps without affecting the fielding restriction count.
How is the 30-yard circle enforced in cricket?
The on-field umpires monitor fielding positions before each delivery. If a fielder is in an illegal position at the moment the bowler delivers the ball, the square leg umpire (or the umpire at the bowler's end, depending on the regulation) calls a no-ball. The fielder cannot be repositioned after the delivery is released.
Is the fielding circle measured from the stumps or the crease?
The 30-yard fielding circle is measured as an oval from each batting crease — meaning it is not a perfect circle from the centre of the pitch but an elongated oval shape that fits the geometry of the pitch.
What is the 'inner circle' in cricket?
In some historical regulations, an inner fielding ring existed within the 30-yard circle, within which a minimum number of fielders had to stand during powerplay overs. Modern ICC regulations have simplified to just the 30-yard circle restriction, without a mandatory inner ring.
