The cricket field and boundary
How the edge of a cricket field is defined and marked, what scores four and what scores six, and why the Laws set no boundary distance while international playing conditions do.
Overview
A cricket field has no fixed size or shape. Grounds differ, and the Laws accept that: what they regulate is how the edge of the field is agreed and marked, not how far away it is.
Before the toss the umpires determine the boundary, and it is then fixed for the whole match. It is marked by a continuous white line or by an object in contact with the ground. Where a line is used, the edge of the line nearest the pitch is the boundary; where an object is used, the same rule applies to its nearest grounded edge.
Four and six
A boundary six is scored only when the ball has been struck by the bat and is first grounded beyond the boundary without having touched the ground inside the field. A boundary four is scored when a ball grounded beyond the boundary either bounced inside first, or was not struck by the bat at all.
That second clause is why a wayward delivery running away to the rope scores four as extras rather than as runs to the batter: the bat never touched it. The allowances themselves — six runs for a boundary six, four for a boundary four — are defaults that can be varied by agreement before the toss.
Where the 65 and 90 yards actually come from
The figures everyone quotes are ICC playing conditions, not Laws. Under the ICC Men's Test Match Playing Conditions no boundary shall be longer than 90 yards (82.29 m) and none should be shorter than 65 yards (59.43 m), measured from the centre of the pitch being used. The aim stated in the same clause is to maximise the playing area at each venue.
The ICC conditions also require the boundary to be marked by a rope or similar approved object placed a minimum of 3 yards (2.74 m) inside the perimeter fencing or advertising boards — a safety margin, so a fielder chasing the ball meets rope rather than hoarding. Grounds already approved for international cricket that cannot meet the minimum are exempt, and simply maximise what they have.
None of this governs a village green. Under the Laws alone, a boundary is wherever the umpires agreed it was before the toss.
Good to know
- The Laws fix no boundary distance — the umpires determine the boundary before the toss and it stays fixed.
- The boundary is the edge of the line or object nearest to the pitch.
- Six requires the ball to be struck by the bat and to clear the boundary without bouncing in the field.
- Four covers everything else that reaches the boundary, including deliveries the bat never touched.
- The familiar 65–90 yard range is an ICC international playing condition, not a Law.

Equipment
- Cricket batA flat-fronted wooden bat used by batters to hit the ball in cricket, with a curved back that concentrates weight behind the hitting area.
- Wickets, stumps and bailsThe three stumps and two bails a bowler aims at and a batter defends — their exact height, width and shape, and what the Laws say about when bails may be dispensed with.

- The table tennis net assemblyThe net, its posts and its suspension — the one height that governs both the net and the posts, and why that number appears twice in the Laws.
- The goal and the creaseThe net a hockey team defends and the protected area in front of it — the exact goal dimensions, what the crease area includes, and why goaltender contact so often disallows a goal.
Positions
- Cricket fielding positionsHow cricket names the places a fielder can stand — the off-side and leg-side halves, the forward and behind-square split, and why the same spot has a different name for each batter.
- Ice hockey positionsThe six players on the ice and what each does — centre, two wings, two defence and the goaltender — plus why hockey substitutes in lines rather than individually.
- Goal attackThe goal attack is a versatile netball attacker who both feeds the shooter and scores goals, moving through the centre and attacking thirds.
- Goal shooterThe goal shooter is a netball attacker who scores goals and is one of only two players allowed to shoot, working within the attacking goal third and circle.
