Turf for a 12 × 10 m lawn, by waste allowance
The lawn is 120 m². Straight edges waste little, and curved edges and awkward shapes waste more. Rolls are the standard 1 m²:

|---|---|---|

| 5% | 126.0 | 126 |
| 10% | 132.0 | 132 |
| 15% | 138.0 | 138 |
Topsoil under the turf, by depth

| Depth of topsoil | Volume (m³) |
|---|---|
| 25 mm | 3.30 |
| 50 mm | 6.60 |
| 75 mm | 9.90 |
| 100 mm | 13.20 |
About a 12 × 10 m lawn
This size is typical of a large lawn. Order turf for delivery the day you are going to lay it, because rolls left stacked start to yellow within a day or two. Lay it in a brick pattern, water well, and keep traffic off it for a couple of weeks. If you would rather seed it, use the lawn seed calculator, and the new lawn materials calculator lists the whole job.
