Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Effective strip width = roll width − overlap. Strips = round up (bed width ÷ effective width). Rolls = round up (strip length × strips × waste factor ÷ roll length).
FAQ
Landscape Fabric Calculator questions
Why overlap landscape-fabric seams?+
Overlap reduces gaps where weeds can emerge and helps keep adjoining strips in place.
How many staples are needed?+
Spacing depends on wind, slope and soil. Use closer spacing at edges, seams and contours.
Should fabric be used under all mulch?+
Not always. The choice depends on planting goals, soil health, drainage and maintenance strategy.
