Cricket Boundaries Explained — When 4 Runs, When 6, and the Rope Rules

Fours and sixes are the most exciting moments in batting — boundaries hit to the rope or over it without running. They also have surprisingly specific rules governing exactly when they count, how many runs are added, and what happens when fielders interfere. Most fans know the basics; the details, including what happens on overthrows and the bump ball exception, are often misunderstood.

Four (4 runs) — the ball reaches the boundary along the ground

A boundary four is scored when the ball, after being hit by the bat, reaches (or crosses) the boundary rope without being caught in the air. The ball only needs to REACH the rope — touching the rope counts. It does NOT need to go over the rope; it just needs to cross the boundary line. The fielder can try to prevent a four by stopping the ball before it reaches the rope; if they touch the rope while the ball is in their hand, it counts as four runs regardless.

Six (6 runs) — the ball clears the boundary in the air

A six is scored when the ball, hit by the bat, crosses the boundary line in the air — without bouncing in the field of play first. The ball must clear the boundary completely in the air. If a ball bounces inside the ground and then rolls over the rope, that scores FOUR (not six). If the ball hits the boundary rope on its way down, it is a six only if it was clearly going over — the umpire judges whether it was airborne when it crossed the line.

Overthrow boundaries

An overthrow boundary is one of the most contentious rules in cricket. If a fielder's throw goes to the boundary, the total runs scored are: the runs the batsmen had already completed before the ball hit the bat or was released by the fielder (whichever happened later), PLUS 4 (for the boundary). This was the rule at the centre of controversy in the 2019 World Cup final, when England's Ben Stokes deflected a throw to the boundary — the umpires awarded 6 runs (2 runs already completed + 4 overthrow boundary).

When a boundary score is NOT counted

• Bump ball — if the ball hits the ground before reaching the bat, a catch off the bounce is not out and does not count as a six. Umpires must judge if the ball hit bat or ground first.
• No-ball — a six off a no-ball still counts as 6 + 1 (the no-ball penalty). The no-ball adds to the total; the six adds to the batter's score.
• Wide — a wide that reaches the boundary counts as 4 wides, not as a boundary to the batter.
• Leg-bye or bye boundary — if the ball goes off the pad (leg-bye) or misses everything (bye) and reaches the boundary, 4 runs are scored as extras, not as runs to the batter.

Boundaries and powerplays

During the powerplay overs (first 6 overs in T20 cricket, first 10 in ODIs), only 2 fielders are permitted outside the 30-metre circle. This restriction is specifically designed to increase the chances of boundary hitting during the powerplay — gaps in the outfield are much easier to find when only 2 fielders can be stationed on the boundary.
