Calculate how much turf you need to cover your garden or space

Not sure on how much turf you need to order? All you really need to do is work out the area you want to cover with turf, if its a square or rectangular shape then just measure the width and length in metres and multiply the two figures together, then add a little extra for cuts and wastage – as a general rule we suggest you order an additional 5% to allow for any errors or waste (our turf calculators will do this for you as standard).

However, if you’re turfing a more complex shaped space such as a circular or triangular garden. Our handy calculators below will be able to help you.

Use Our Turf Calculator to Measure for a Square or Rectangle

If you’re unsure on how many rolls of turf you require we can help. Getting the correct measurement for a square or rectangle shaped lawn is actually very straight-forward, simply measure the length and width. Follow the steps below:

  1. Measure and enter the length of your lawn in metres and add into the “Length” field;
  2. Measure the width of your lawn in metres and add it into the “Width” field;
  3. The tool will then give you the total coverage needed for your area and a second total that includes an additional 5%.

It’s good practice and we recommend to order an additional 5-10% to account for any wastages. Following this guidance will ensure that you have enough for the area you wish to turf.

For example:

Let say that the length of your space is 10m and the width is 7m. Multiply the length (10m) by the width (7m) to get the total coverage needed, which is 70m2.

How to Calculate How Much Turf is Needed for a Circle

To measure for a circle or rounded garden, the forula for this is slightly different, but also fairly straight-forward.

To measure a round space:

  1. Measure the diameter of the circle;
  2. Divide the diameter by 2 to give you the radius;
  3. Square the radius (multiply the radius by itself);
  4. Coverage area = 3.14 x squared radius

For example:

Let’s say you have a circle that is 10m in diameter. The radius would be 5m. The squared radius is 25m2. We can multiply 25m2 x 3.14 to get the coverage area which would be 78.5m2.

How to Measure for a Triangular Space

Measuring turf for a triangle shape can get a little more complicated, but you can follow this step by step process to help you. We’ve even included an example to provide some extra context for you:

  1. Take the base of the triangle in metres (this is the longest side);
  2. Take the height of the triangle;
  3. Use the following formula to calculate the area;
  4. 0.5 x base x height

For example:

Let’s assume the base of the triangle is 6m and the height is 4m. Multiply 0.5 x 6 x 4 to get the total area, which would be 12m2 of turf.
