Line Marking - Finding a Right Angle | Grounds Management Toolkit

One of the most tried and tested methods of finding a right angle is by using the 3,4,5 method. This method is essential when marking out a pitch for the first time. The five step guide set out below guides you through step by step ensuring you will end up with a pitch that is square.

1. Place a taut line to produce the base line and mark the corner positions A and B.
2. From the corner peg A extend a tape for 30m point X. Extend a tape 40m from A to Y. The distance from Y to X must be 50m, which will give a right angle at A.
3. Extend the line A - Y for a length of 90 - 120m to identify the 3rd corner peg of the pitch at point C.
4. From the corner peg B extend a tape for 30m point W. Extend a tape 40m from B-Z. The distance from Z-W must be 50m which will give you a right angle at B.
5. Extend the line B - Z to the required length to produce the 4th corner peg at point D. A complete rectangle is now made for the pitch. The accuracy can be checked by measuring the diagonals A - D and B - C.
