Measuring your lawn

If you plan to turf your garden yourself, and you are unsure of how much turf you require, here are some simple formulas for working out the required amount.

Note: You need to add an extra 5% to your total, to allow for wastage.

If the area of the lawn is circular, measure as follows:

Area = 3.14 x r²



Example: Circle's radius (r) is 10 metres. Multiply 3.14 by the radius squared as follows:
A = 3.14 x 10²
A = 3.14 x 100
A = 314 square metres

If the area is a Square or Rectangle:

Area = length x width

Example: Square's or rectangle's base is 10 metres, and the square's or rectangle's height is 10 metres.

A = 10 x 10
A = 100 square metres

If the area is Triangular:

Area = (Base x Height) / 2

Example: Triangle's base is 10 metres and the height (base to point) is 20 metres.

A = (10 x 20) / 2
A = 200 / 2
A = 100 square metres

If the area is a Combination Freeform :

1. Draw a sketch of the area you want to lay turf onto.
2. Draw rectangles or circles over your sketch (they should not overlap).
3. Whilst standing in the area due to be turfed, mark out the corners of your rectangles on the ground, and the radius of any circles.
4. Measure and record on your sketch, the lengths and widths of all your rectangles and the circle radius.
5. Calculate the area of each rectangle and circle.
6. Add the areas together. This is approximately the amount of turf you will need.

Example:
Circle (1) A = 3.14 x r²
Rectangle (2) A = b x h
Square (3) A = b x h
