What is a 30-Yard Circle in Cricket?

While watching a cricket match, you must have noticed a dotted line or a continuous white line marked some distance from the pitch.

That’s the inner circle, best known as the 30-yard circle.

But why is it called the 30-yard circle? And what’s the purpose behind it?

Let’s understand the 30-yard circle marked on cricket fields.

The Inner Circle

The 30-yard circle is applicable to only limited-overs matches, like ODI, T20, T10, or the Hundred. You won’t see the inner circle marked on the field for a Test or First-Class match.

The inner circle is officially known as the fielding restriction circle. 2 semi-circles joined by 2 parallel lines form the fielding restriction circle.

The semi-circles are marked at the 30-yard distance from the middle stump on both ends of the pitch. The semi-circles and parallel lines are drawn with continuous white lines or dots at a 5-yard distance.

If dots are drawn, then they need to be covered with 7 inches of white plastic or rubber discs.

This is the standard fielding restriction circle for every men’s limited-overs cricket match. But when it comes to women’s cricket, the inner circle is marked at 25.15 yards.

Why is it called the 30-yard circle?

Well, it derives the name from the distance it is marked at. Since the semi-circles lie 30 yards from both ends, it’s commonly referred to as the 30-yard circle.

What is the purpose of the 30-yard circle?

The purpose of the 30-yard circle is to implement fielding restrictions. The inner circle puts limitations on the fielding side while placing the fielders throughout the match.

This also brings a strategic arc to the game, as captains need to think tactically while positioning the fielders on the field.
