The singles court is 78ft long (23.77m) and divided in half by a net suspended over the tops of two posts.
The net should be 3ft high at its centre.
The singles court is 27ft wide (8.23m).
In doubles, the addition of 4.5ft (1.4m) 'tramlines' along either side court increases the width to 36ft (11m).
The court is edged by sidelines and a baseline at the end.
The service area is marked by a line 21ft (6.4m) from the net and parallel to it.
It is divided in half to form the two service boxes.
If any part of the ball hits the line, it's judged to be in or 'good'.
