How to measure your garden for turf
Knowing your lawn size helps you get an accurate quote. Use our calculator below: add a shape for each part of your lawn, and it works out the area and roughly how many rolls of turf it needs.
Garden turf calculator
Add a shape for each part of your lawn. Measurements in metres.
0 m² of lawn
About 0 rolls of turf, at roughly one roll per m² with your offcut allowance.
Each roll of turf covers about 1 m² (around 2.4 m long by 40 cm wide). We work out the turf for you when we quote, so this is a guide.
How to measure a lawn
Sketch it
Draw a rough plan of the lawn, leaving out borders, paths and patios.
Split it into simple shapes
Rectangles for most of it, a circle or triangle for odd bits.
Measure each shape
Use a tape measure in metres. For a circle, measure straight across the middle.
Enter them in the calculator
Add a shape for each part and the total appears below.
Allow for offcuts
5% suits most lawns; choose 10% if there are lots of curves.
Awkward shapes
Few lawns are perfect rectangles. A few tips:
- L-shaped lawns: split into two rectangles and add them
- Curved borders: measure to the furthest point of the curve and choose the 10% allowance
- Lawns that taper: measure the width at both ends and use the average
- Island beds: work out the bed as a shape and subtract it, or simply leave it in, as a bit extra does no harm
Worked examples
| Lawn | Area | Rolls with 5% extra |
|---|---|---|
| 4 m × 3 m yard lawn | 12 m² | 13 |
| 5 m × 4 m back lawn | 20 m² | 21 |
| 10 m × 6 m semi garden | 60 m² | 63 |
| 8 m × 5 m plus a 3 m × 2 m nook | 46 m² | 49 |

Common questions
Why add extra for offcuts?
Turf is cut to fit edges, curves and corners, so a little is always trimmed off. Around 5% covers most lawns.
How big is a roll of turf?
About 1 m², usually around 2.4 m long and 0.4 m wide.
