How to Measure

Before you work out what materials you need to order and purchase, you will first need to measure up your space. Always measure in metres as you are looking for a final measurement in metres squared (m2). Below are some tips on measuring for both instant and artificial lawn.

Some lawn areas are straight forward as they are a clear single shape, however other areas may be a combination of shapes (e.g. a square and a circle), which can make it a bit trickier. Below are some suggestions regarding different shapes and how to measure to ensure you get the most accurate number for ordering your lawn. If you do have an irregular shaped lawn area, divide it into regular shapes, calculate the individual area of those shapes and add them together to get an overall measurement.


For a square, rectangle or oval, you need to multiply the length by the width.

Formula: L x W = m2

Example: If a lawn has a length of 6 metres and a width of 15 metres you need to multiply 6 by 15.

Sum: 6 x 15 = 90m2


Alternatively, if your lawn is a circular shape, measure the diameter (length from one side to the other). Divide the diameter by 2 to get the radius (R) of the circle. Using the radius, complete the following formula to get the area of your circle.

Formula: R x R x 3.14 = m2

For example, if your circle has a diameter of 13 metres, the radius is 6.5 metres and the sum below is needed to work out the area of your circle.

Sum: 6.5 x 6.5 x 3.14 = 132.7m2


To calculate the area of a triangle, measure the base and one side of the triangle. You will need to multiply the base (B) by the side (S) and divide it by two to get the overall area.

Formula: B x S ÷ 2 = m2

For example, if your lawn has a base of 16 metres and a side of 9 metres the sum below would be required to work out the area of your triangle.

Sum: 16 x 9 ÷ 2 = 72m2

Please Note:

  • It is advisable to allow extra turf when ordering as you will have some wastage, especially if your lawn is of an irregular shape.
  • Know the size of your panels when ordering artificial turf so that you do not have to cut them any more than needed.
