Where the figures come from

This sum uses only the numbers you entered.

How much turf do I need?

Multiply the lawn's length by its width to get square metres, then divide by the area one roll covers. Your turf supplier gives the size of a roll. For a curved lawn, use the area calculator to add up the shapes, then enter the length and width of a rectangle with the same area.
