In cricket, a boundary is the edge of the field, usually marked by a rope. When the batter hits the ball all the way to it, the team scores extra runs without having to run - 4 runs if the ball touched the ground on the way, or 6 runs if it cleared the boundary in the air. Here is a simple guide to how boundary rules work.
Boundaries are the fastest way to score in cricket. Most big innings are built on fours and sixes, so it helps to know exactly when each one counts and when it does not.
What Is a Boundary in Cricket?

The boundary is the line that marks the edge of the playing area. It is usually shown by a rope laid on the grass, and sometimes a painted line or a fence. Everything inside it is in play. The moment the ball reaches or crosses it, it is a boundary, runs are added, and the ball is dead until the next delivery.
How You Score Four Runs
You score 4 runs when the ball reaches the boundary after touching the ground at least once. It does not matter if it rolls along the grass or bounces on the way - as long as it touches the ground inside the field and then reaches or crosses the rope, it is a four. The batters do not need to run; the 4 runs are added automatically.
How You Score Six Runs
You score 6 runs when the ball clears the boundary on the full - meaning it flies over the rope without touching the ground inside the field first. A six can only be scored off the bat (including the glove holding the bat). Just like a four, the batters do not run for it; the 6 runs are added straight away.
When Does the Ball Count as Crossing the Boundary?
The ball counts as a boundary the moment it touches the rope, touches the ground beyond it, or touches anything that is on or over the line. So if the ball hits the rope, it is a four (or six) even if a fielder then picks it up. And if a fielder stops the ball but is touching the rope at that moment, it still counts as a boundary.
Catches on the Boundary
This is where many people get confused. For a catch near the rope to be out, the fielder must not be touching the boundary or the ground beyond it while holding the ball. If a fielder catches it but their foot is on the rope, it is a six, not a wicket. Fielders can jump from inside the boundary, catch or knock the ball back while in the air, and complete the catch - as long as they take off from inside and stay inside the field. If their momentum carries them over the rope while still holding the ball, the catch does not count.
Boundaries From Overthrows
Sometimes the ball reaches the boundary by accident. For example, a fielder throws it back towards the stumps and it runs away to the rope - this is called an overthrow. The batting side gets the 4 runs for the boundary plus any runs the batters had already completed before the throw, so one bad throw can cost several runs at once.
Byes, Leg Byes and No-Balls
Boundaries are not only scored off the bat. If the ball runs all the way to the rope as byes (it missed the bat and body) or leg byes (it came off the body), the team still gets 4 runs - but those go to the team's extras, not to the batter. A no-ball or wide that reaches the boundary adds the penalty run plus the 4. A six, however, can only come off the bat.
How Big Is a Cricket Boundary?

There is no single fixed size - grounds vary. In international cricket the boundary is usually no more than 90 yards and no less than 65 yards from the centre of the pitch. Club, school, and backyard grounds are often much smaller. Bigger boundaries make sixes harder to hit; smaller ones make big hitting easier.
Quick Summary
4 runs: the ball reaches the boundary after touching the ground.
6 runs: the ball clears the boundary in the air, off the bat.
Touching the rope counts as a boundary.
A fielder touching the rope while holding the ball makes it a boundary, not a catch.
Byes and leg byes can reach the boundary too, but those runs go to extras.
Conclusion
Boundary rules are simple once you know the key question: did the ball touch the ground before it reached the rope? If yes, it is four. If it flew over on the full, it is six. Add in the rules for catches on the rope and overthrows, and you will understand almost every boundary you see in a match.
Frequently Asked Questions
Q1: What is the difference between a four and a six in cricket?
A: A four is scored when the ball reaches the boundary after touching the ground. A six is scored when the ball clears the boundary in the air without bouncing. Both are hit off the bat and neither needs the batters to run.
Q2: Does it count as a boundary if the ball hits the rope?
A: Yes. The moment the ball touches the boundary rope it is a boundary - a four if it bounced first, or a six if it got there on the full. It counts even if a fielder picks it up straight after.
Q3: Is it out if a fielder catches the ball but touches the boundary rope?
A: No. If the fielder is touching the rope or the ground beyond it while holding the ball, it is a six, not a catch. The fielder must stay inside the boundary for the catch to count.
Q4: Can you score a six off your body or pads?
A: No. A six can only be scored off the bat (or the glove holding the bat). If the ball comes off your body and reaches the boundary on the full, it does not count as a six, and runs off the body are leg byes, which go to the team's extras.
