LBW Rule in Cricket Explained Simply

LBW — leg before wicket — is one of the most misunderstood dismissals in cricket. Players argue about it in street games, club matches and professional cricket alike. This guide explains the rule clearly: the three conditions that must all be met for an LBW decision, the off-stump exception, and the most common scenarios where batters are and are not out.

What LBW Means

LBW means a batter is dismissed because their body — leg, pad, or any part of their person — has intercepted a ball that would otherwise have hit the stumps. The law exists to prevent batters from simply blocking the stumps with their body when they cannot or do not want to hit the ball.

The LBW rule does not apply in most gully cricket matches, where it is excluded by convention because there is no neutral umpire to adjudicate. In formal leather-ball cricket, however, it is one of the ten ways a batter can be dismissed.

The Three Conditions for Out

All three of these conditions must be satisfied simultaneously for an LBW decision to stand. If any one of them is not met, the batter is not out.

1. Pitching in Line

The ball must pitch either on the line of the stumps or outside the line of the off stump. A ball that pitches outside the line of the leg stump can never result in an LBW dismissal — no matter where it goes after pitching or where it strikes the batter. This is absolute. If the ball pitches down leg, an LBW appeal should always be turned down.

2. Impact in Line

The ball must strike the batter's body in line with the stumps — between the off-stump line and the leg-stump line. There is one important exception to this: if the batter is not playing a shot, they can still be given out LBW even if the impact is outside the off-stump line, provided the ball would have gone on to hit the stumps. If the batter is playing a shot and the impact is outside the off-stump line, they cannot be out LBW regardless of whether the ball would have hit the stumps.

3. Hitting the Stumps

Ball-tracking technology (Hawk-Eye, used in DRS) assesses whether the ball would have hit the stumps. In an on-field decision without DRS, the umpire makes this judgement based on the delivery's trajectory from pitch to impact. The ball must be predicted to hit the stumps — middle, off, or leg — somewhere between the top of the off stump and the base of the leg stump.

The Off-Stump Exception (Playing a Shot)

This is the part of the LBW law that causes the most confusion:

• If the ball pitches outside off stump and the batter plays a genuine shot at it, the batter cannot be given out LBW — even if the ball strikes the pad in line and would have hit the stumps.
• If the ball pitches outside off stump and the batter offers no shot, the batter can be given out LBW — provided the impact is in line and the ball would have hit the stumps.
• If the ball pitches on the stumps (in line), the batter can be given out LBW whether or not they play a shot.

The phrase 'playing a genuine shot' is a judgement call. A batter who lifts the bat high but leads with the pad and makes no real attempt to hit the ball is not playing a genuine shot. Umpires and DRS reviews assess this in real time.

Common LBW Scenarios

These examples illustrate how the three conditions play out in practice:

• Scenario A — Out: An inswinger from over the wicket pitches on off stump, strikes the front pad in line with middle and leg stump, and tracking shows it hitting middle stump. All three conditions met — out LBW.
• Scenario B — Not out (pitches outside leg): A leg-spinner's googly pitches a foot outside leg stump and strikes the batter's front pad. No matter where it would have gone — not out. The pitching-in-line condition fails.
• Scenario C — Not out (playing a shot, impact outside off): An offspinner pitches just outside off stump and the batter plays a drive, missing the ball. It strikes their front pad just outside the off-stump line. The batter is playing a shot and the impact is outside off stump — not out.
• Scenario D — Out (no shot, impact outside off): A medium pacer pitches outside off stump and nips back in. The batter does not offer a shot. The ball strikes their front pad outside the off-stump line but tracking shows it hitting off stump. No shot played — out LBW.
• Scenario E — Not out (would miss the stumps): A straight ball pitches on middle stump and strikes the batter's back pad halfway up. Tracking shows the ball passing over the top of off stump. Would miss — not out.

Frequently Asked Questions

What is the LBW rule in cricket?

The LBW (leg before wicket) rule means a batter is out if the ball would have hit the stumps but strikes their leg or body first, provided it pitches in line or outside off stump and the batter is not playing a genuine shot at a ball outside off.

Can a ball pitching outside leg stump result in an LBW decision?

No. A ball that pitches outside the line of leg stump can never result in an LBW dismissal regardless of where it strikes the batter or where it would have gone on to hit. If the ball pitches outside leg stump, the umpire must rule not out to any LBW appeal.

What is the playing-a-shot exception in the LBW rule?

The playing-a-shot exception means that if the ball pitches outside the line of off stump and the batter plays a genuine shot at the delivery, the batter cannot be given out LBW even if the ball strikes the pad in line and would have hit the stumps. This exception does not apply if the batter offers no shot, or if the ball pitches on the line of the stumps.

Can you be out LBW to a ball that pitches on the stumps even while playing a shot?

Yes. If the ball pitches on the line of the stumps — in line between off and leg — the batter can be out LBW whether or not they play a shot. The playing-a-shot exception only protects the batter when the ball pitches outside the off-stump line. A ball pitching in line removes that protection entirely.

How does DRS affect LBW decisions in cricket?

In matches with the Decision Review System (DRS), teams can challenge on-field LBW decisions. Ball-tracking technology predicts whether the ball would have hit the stumps. If the ball is predicted to hit more than half the stump, the on-field decision is overturned. If the impact is outside the off-stump line, the system also checks whether the batter was playing a shot. DRS has made LBW decisions significantly more accurate at the professional level.
