What Is LBW in Cricket? Leg Before Wicket Explained

Few dismissals cause as much argument as leg before wicket. It asks the umpire to judge not just what happened, but what would have happened if the batter’s pad hadn’t been in the way. That hypothetical is why LBW feels complicated, but the law itself follows a clear checklist.

The basic idea

A batter is out LBW when the ball hits their body, almost always the pad, and would have gone on to hit the stumps. The batter is, in effect, using their leg to stop a ball that was heading for the wicket, so the law rules them out.

The tricky part is that several conditions all have to be satisfied before the umpire can raise the finger.

The conditions umpires check

For an LBW to be given, the umpire works through these questions:

Question	Requirement
Where did the ball pitch?	In line with the stumps or on the off side — not outside leg stump
Where did it hit the batter?	In line with the stumps, unless the batter offered no shot
Was it going to hit the stumps?	Yes, the ball must be shown to be hitting the wicket

There is one important exception: if the ball strikes the pad outside the off stump but the batter made a genuine attempt to play a shot, they cannot be given out.

How DRS changed close calls

Modern cricket uses the Decision Review System to settle tight LBW appeals. Ball-tracking technology predicts the path the ball would have taken and shows whether it was hitting the stumps.

When the prediction is marginal, for example the ball just clipping the top or side of a stump, the decision falls under umpire’s call: the on-field umpire’s original ruling stands. That is why two nearly identical deliveries can produce different results depending on what the umpire first decided.

Why the law is built this way

The conditions exist to keep the contest fair between bat and ball. Without the “pitching outside leg” protection, bowlers could aim down the leg side and trap batters cheaply. Without the “hitting in line” rule, a batter could be given out to a ball missing the stumps. Put together, the checklist makes sure LBW only rewards deliveries that were genuinely going to hit the wicket, which is exactly why it remains one of cricket’s most scrutinised decisions.
