How to work out how much turf you need
Turf is sold by the roll, so you need to turn your lawn area into a number of whole rolls. Measure the area, add an allowance for cuts and waste, then divide by the coverage of one roll from your supplier. If you are laying topsoil underneath, work out its volume from the area and the depth.
- Choose metres or feet, then enter the lawn area in square metres or square feet. Measure each section and add them together. For a single rectangle, Work out the area multiplies length by width for you.
- Add a cuts and waste allowance as a percentage. Change the starting allowance to suit the layout: simple rectangles need less, while curved edges and narrow strips need more.
- Enter the area one roll covers, in the same unit as the lawn. Check it with your supplier, as roll sizes differ.
- The calculator divides the area, including the allowance, by the area per roll and rounds up to whole rolls. It also shows the area those whole rolls deliver.
- If you need topsoil or underlay, enter the depth in millimetres or inches. The calculator works out the volume for the measured lawn, before the allowance, in cubic metres or cubic yards.
- Add a price per roll and a topsoil price per cubic metre or cubic yard if you want a materials cost.
Tips and common mistakes
- Measure in the same unit throughout. Mixing metres and feet is a common cause of ordering far too much or too little.
- Confirm the roll size before ordering. Two suppliers can sell rolls of different sizes, which changes the count.
- Lay turf soon after delivery. It does not keep well in the roll, so plan the delivery for when you are ready to lay.
- Keep curved or awkward lawns in mind when setting the waste allowance. Trimming around beds and edges uses more turf.
Questions
How much turf do I need?
Measure the lawn area, add an allowance for cuts and waste, and divide by the coverage of one roll from your supplier. Round up to the next whole roll. For example, if your area with allowance is 52 m² and a roll covers 1 m², you would order 52 rolls.
How do I measure my garden for turf?
Split the area into rectangles, triangles and circles, work out each area and add them up. For a rectangle, multiply length by width. Measure in either metres or feet and stick to one unit.
How much extra turf should I order?
Add a percentage for cuts and waste based on the shape of the lawn. A simple rectangle needs only a little extra, while curves, paths and beds need more. Your supplier can also advise for your layout.
How much topsoil do I need under turf?
Multiply the lawn area by the depth of soil you plan to spread. In metric, area in square metres times depth in metres gives cubic metres. The calculator takes the depth in millimetres or inches and does this for you. Ask your supplier for the depth they recommend for your turf and soil conditions.
How many square feet are in a square metre?
One square metre is about 10.76 square feet. To convert square feet to square metres, divide by about 10.76.
