Estimate landscape fabric area and roll length from bed dimensions, roll width and overlap allowance.

How it works

Fabric area = bed area × (1 + overlap/waste). Required roll length = purchase area ÷ roll width.

Planning estimates depend on your measurements, product labels, material density and site conditions. For purchased products, follow the manufacturer's label.
