The LBW (Leg Before Wicket) rule is one of cricket’s most debated and complex dismissal methods. Here’s a quick breakdown of what you need to know:
- What is LBW? A batter is out if their body (excluding the hand holding the bat) blocks the ball from hitting the stumps.
- Key Factors for LBW Decisions:
- Where the ball lands: It must pitch in line with the stumps or outside the off stump. If it pitches outside the leg stump, the batter cannot be out LBW.
- Impact point: The ball must hit the batter in line with the stumps unless no shot is offered.
- Ball’s trajectory: The ball must be predicted to hit the stumps.
- Shot attempt: If no shot is played, LBW can apply even if the ball hits outside the off stump.
- Technology like DRS: Ball tracking helps umpires make more accurate decisions, but "Umpire’s Call" preserves the role of on-field decisions.
Quick LBW Facts:
- LBW was introduced in 1774 to prevent batters from unfairly using their legs to block the ball.
- Modern tools like Hawk-Eye have improved accuracy, with over 95% correct LBW decisions in international matches.
- Umpire’s Call: Marginal decisions rely on on-field calls, balancing technology with human judgment.
This guide helps players, umpires, and fans navigate the complexities of LBW decisions in cricket. Read on for detailed rules, tips for avoiding LBW dismissals, and how technology shapes these decisions.
Leg Before Wicket (LBW) Explained
Key Parts of an LBW Decision
When it comes to LBW decisions, umpires have to consider multiple factors to determine if the ball would have hit the stumps. Knowing these details can help players and fans better understand how these calls are made.
Ball Position Rules
The ball’s position at two key moments plays a major role in an LBW decision:
- The ball must pitch in line with the stumps or on the off side. If it pitches on the leg side, the appeal is automatically dismissed.
- If the ball hits the batter outside the off-stump line while they are attempting a genuine shot, the appeal is also dismissed.
Once this is established, umpires shift their focus to the ball’s trajectory toward the stumps.
Path to the Stumps
Umpires then assess whether the ball would have hit the stumps if the batter hadn’t interfered. This involves judging the ball’s trajectory, the height of the impact, and the batter’s distance from the stumps.
Shot vs No Shot
The batter’s intent to play a shot is another critical factor in LBW rulings:
- If the batter plays a genuine shot and the ball pitches outside the off stump, LBW cannot be given.
- However, if no shot is offered and the ball is heading for the stumps – even if it pitches outside the off stump – the batter can be ruled out.
This rule was introduced in response to the overuse of pad play during the 1950s and 1960s, which many saw as an unfair tactic.
In modern cricket, the Decision Review System (DRS) requires that at least 50% of the ball is predicted to hit the stumps for an LBW decision to be upheld.
LBW Rules: Facts vs Myths
Leg-Side Pitch Rule
The leg-side pitch rule is often misunderstood. Here’s the deal: if the ball pitches outside the leg stump, the batter cannot be given out LBW. This holds true even if the ball would have gone on to hit the stumps. Why does this rule exist? It was introduced to discourage negative bowling strategies that make scoring runs nearly impossible. By setting a clear reference point, the rule ensures fair and consistent decisions.
Now, let’s dive into how pad contact influences LBW rulings.
Pad Contact Rules
Pad contact plays a key role in LBW decisions, but the rules can get tricky. Here’s what you need to know:
- If the ball hits the pad outside the off stump, the decision depends on whether the batter tried to play a shot.
- If no shot is attempted, the batter can still be given out, even if the ball made contact outside the off stump.
When making these calls, umpires assume the ball would have continued on its path, even if it might have bounced before hitting the stumps.
Technology Requirements
Technology has added a new layer to LBW decisions. Tools like ball-tracking systems have provided fresh insights. For example:
"With the passage of time and the adoption of Hawkeye into other sports, together with presentations demonstrating its accuracy, cricket followers seem gradually to have accepted its predictions. Replay analyses have shown that a greater proportion of balls striking an outstretched leg go on to hit the wicket than had once been expected."
– Douglas Miller
Dave Richardson, ICC General Manager, also highlighted the impact of technology:
"Umpires may have realised that if they give someone out and DRS shows it was not out, then their decision can be rectified. So they might, I suppose, have the courage of their convictions a bit more and take a less conservative approach to giving the batter out. I think if we’re totally honest, DRS has affected the game slightly more than we thought it would."
– Dave Richardson, ICC General Manager
Even with these advancements, umpires still make LBW decisions based on their judgment when DRS isn’t available. The traditional approach remains a trusted method in many matches.

DRS and LBW Decisions
LBW decisions have always been a tricky aspect of cricket, but modern technology has added a new layer of precision. By combining traditional umpiring with advanced tools, these decisions are now more accurate and reliable.
Ball Tracking Basics
Ball tracking technology has revolutionized how LBW decisions are made. Using up to 10 high-speed cameras, the system tracks the ball’s movement from various angles, creating a 3D model of its trajectory. This tool, often powered by Hawk-Eye, has an average error margin of just 3.6 millimeters. Such precision has made it an essential part of the decision-making process in cricket.
What is Umpire’s Call
Umpire’s Call strikes a balance between technological accuracy and the on-field umpire’s authority. It addresses situations where ball tracking shows a marginal call, either in the Impact Zone or the Wicket Zone.
| Scenario | Original Decision | DRS Requirement to Overturn |
|---|---|---|
| Given Out | Ball completely missing | Must show ball missing stumps entirely |
| Not Out | Ball hitting stumps | More than 50% of ball must be hitting stumps |
"The principle underpinning DRS was to correct clear errors in the game whilst ensuring the role of the umpire as the decision maker on the field of play was preserved, bearing in mind the element of prediction involved with the technology. Umpire’s Call allows that to happen, which is why it is important it remains."
This approach ensures that technology aids decisions without undermining the role of the umpire.
Using DRS Reviews
Each team gets two unsuccessful reviews per innings, as seen in the 2023 ODI World Cup. Here’s how players can make the most of them:
- Check the basics: Ensure the ball didn’t pitch outside the leg stump.
- Evaluate the impact point: At least 50% of the ball must be in line with the stumps.
- Confirm the outcome: Make sure the ball would hit the stumps and not pass over.
"My personal opinion is that if the ball is hitting the stumps, it is hitting the stumps. They should take away the umpire’s call, if I’m being perfectly honest."
"You need the umpire’s call. It’s not there to back up the umpire; it’s to give the margin of error for the technology. Umpires will give virtually everything out because they think it will be clipping, and we will have more two-day Test matches."
These differing views highlight the ongoing debate about the role of Umpire’s Call in modern cricket.
LBW Guide for Players and Fans
Understanding LBW decisions can help players improve their game and fans better enjoy the sport. Here’s how both groups can approach this crucial part of cricket.
Batting Against LBW
To avoid LBW dismissals, focus on footwork and positioning:
- Front Foot Defense: Step forward to meet the ball early. This improves your ability to judge the line and stay aligned with the stumps.
- Back Foot Technique: Quick back-foot movement helps you adjust to balls of varying lengths.
Adopting an attacking mindset can also reduce LBW risks. Here are some tips:
- Play attacking shots to disrupt the bowler’s rhythm.
- Use defensive blocks carefully; they require perfect timing.
- Leave balls that aren’t heading toward the stumps.
Bowling for LBW
Bowlers can increase LBW chances by mixing up their line, length, and delivery angles. Bowling from around the wicket is particularly effective in unsettling the batsman’s rhythm.
"Off spin around is one of my favorite types of bowling… it can be very difficult to get away for a batsman and if the ball is turning a lot, brings in short leg for catches."
"I like bowling my offspin round, because with 2 or 3 variations (arm-ball, topspinner…) you can get rid of sloggers when no-one else can! High-risk tactics, of course, but it usually pays off."
Reading LBW Decisions
For both players and fans, understanding LBW decisions adds depth to the game.
With ball-tracking technology, the accuracy of LBW calls in international matches has risen to over 95%. Interestingly, 74% of referrals involve LBW decisions, though only 22% are successful.
When evaluating LBW appeals, these factors are crucial:
- Where the ball strikes the pad.
- Whether the ball pitched outside the leg stump.
- The projected path of the ball toward the stumps.
"Somebody is unhappy with the onfield decision and that is the only reason they have gone upstairs to the third umpire and when that happens, let the technology take over. In tennis, as in cricket, a call is either in or out",
Modern technology has become a critical tool in ensuring fair and accurate LBW decisions.
Quick LBW Reference Guide
Here’s a quick breakdown of the key factors involved in LBW decisions:
| Decision Factor | What Umpires Check | Key Points |
|---|---|---|
| Ball Pitch | Where the ball lands | Cannot pitch outside the leg stump |
| Impact Point | Where the ball hits the pad | Must align with the stumps if a shot is played |
| Trajectory | Ball’s predicted path | Must show the ball hitting the stumps |
| Shot Attempt | Batter’s intent | Influences how the impact point is judged |
These factors form the basis of the three main zones considered in LBW decisions:
- Pitching Zone: Where the ball lands on the pitch.
- Impact Zone: The exact point where the ball hits the pad.
- Wicket Zone: The ball’s projected path toward the stumps.
Important Technical Details
- Ball-tracking must show that more than 50% of the ball is hitting the stumps to overturn a "not out" decision.
- The pitching zone is non-negotiable – there’s no "umpire’s call" on where the ball lands.
- The height and distance from the stumps at the moment of impact are critical for determining the outcome.
How DRS Reviews Work
When a Decision Review System (DRS) is used, it evaluates:
- Pitching location: This is an absolute decision with no margin for error.
- Impact with the pad: Judged using the "umpire’s call" margin.
- Projected path to the stumps: Also assessed with the "umpire’s call" margin.
Finally, the rule against pitching outside the leg stump is in place to prevent overly defensive bowling strategies that could unfairly hinder the batter.
As a lifelong Australian cricket fan and now at the age of 72, I have never truly understood the LBW rule (to my shame). To put it better, I understand how the law is applied but not the reasoning.
This applies particularly for the pitching outside leg stump and the impact outside off conditions.
I understand the theory about reducing negative play but as stated the LBW rule was introduced to stop a batsman using his pads to defend the stumps.
My thought is that if a bowler pitches a delivery anywhere on the legal playing surface and it hits the pad, whether playing a shot or not, and if technology shows it going on to hit the stumps, it should be out. Possible exception should be if it deviates violently after hitting a foreign object on the pitch
After all, if the pad is not in the way, it is going to bowl the batsman and he will be given out.
I see these decisions all the time. Everyone gets excited about the batsman being plumb LBW then the groan of disappointment when the video shows the ball pitching an inch outside leg negates that.
The laws of cricket can be confusing for us old folk. I also have thoughts about what should constitute a fair catch, but I’ll save that for another time.
I think you’re right, it does seem a madness now – perhaps this is a relic of the days of uncovered pitches and bigger movement for seam and spin, maybe they wanted to give batsmen more chance against big movement.
