Boundaries and Sixes Explained: Four and Six Rules in Cricket
The rules governing boundaries and sixes in cricket — when a shot scores four runs (ball crosses boundary after bouncing or rolling), when it scores six (ball crosses boundary without bouncing), and the fielder boundary rules.
A boundary in cricket refers to the rope or line marking the edge of the playing field. When the ball reaches or crosses the boundary, runs are automatically awarded: four runs if the ball crosses the boundary after touching the ground at least once (ground boundary); six runs if the ball crosses the boundary without touching the ground (over the rope without bouncing — a six). The batter and batting partner stop running when a boundary is scored — the four or six runs are awarded automatically regardless of how many runs the batters had already physically run.
Scoring Four Runs
A ball scores four runs when it reaches or crosses the boundary after at least one contact with the ground — this includes shots that bounce once before the boundary, that roll along the ground to the boundary, or that bounce off the pitch and travel to the boundary through the outfield. The ball does not need to physically cross the rope — if a fielder touches or stops the ball on or near the boundary while in contact with the rope themselves, four runs are awarded (the ball is treated as having crossed the boundary if a fielder grounds the ball against the rope).
Scoring Six Runs
Six runs are awarded when the ball crosses the boundary without touching the ground — hit directly over the boundary rope from the bat, without bouncing. The ball must cross completely — if it lands on the rope (not past it), the umpires adjudicate. In modern cricket, boundary ropes make this easier to judge than old-style boundary lines. If a fielder catches the ball near the boundary and then steps back to touch or ground the ball on the rope, six runs are awarded even if they initially appeared to have caught it — the contact with the boundary makes it a six.
Fielder and Boundary Interactions
Specific fielder-boundary interactions: if a fielder catches a ball near the boundary and then steps out of the field of play (crosses the boundary rope while catching or immediately after), the ball is dead and six runs are awarded — not a catch. If a fielder is inside the boundary, catches the ball, then deliberately throws it back into play before stepping out, then re-enters the field and catches it again, the catch is valid (providing continuous control through the sequence). This sequence is allowed under the Laws but must be executed within the same fielder's hands — it cannot pass through another fielder's hands and still count.
Frequently asked questions
How many runs is a boundary in cricket?
Four runs if the ball crosses the boundary after touching the ground. Six runs if the ball crosses the boundary without touching the ground (hit directly over the rope). Runs being physically run at the time of the boundary are abandoned — the four or six is awarded automatically.
What happens if a fielder steps on the boundary while catching?
If the fielder has any part of their body in contact with the boundary rope or ground outside the boundary while completing the catch, six runs are awarded — not out caught. The fielder can jump from inside the field, catch the ball while airborne, and complete the catch validly — as long as their feet land inside the field.
Can a fielder throw the ball back into play from outside the boundary?
Yes — a fielder can catch the ball near the boundary, throw it back into play before crossing the rope, then re-enter the field and catch it again for a valid dismissal. However, the ball cannot pass through another fielder's hands during this sequence. The fielder must maintain continuous involvement.
