Why does overlap affect roll usage?
Adjacent strips share covered width at each seam, reducing the effective width of every strip after the first.

Landscape Fabric Calculator — Rolls, Overlap & Staples
Estimate landscape-fabric strips, roll count, overlap allowance, seam length and ground staples for a rectangular bed or path.
Result
2 roll(s)
6 strip(s) · 180 linear ft of 4 ft fabric
150 ft internal seams · about 125 staples.
Formula and worked example
Strips = ceil((bed width − overlap) ÷ (roll width − overlap)); fabric length = strips × bed length; staples ≈ ceil((perimeter + seam length) ÷ spacing).
A 30 × 20 ft bed covered with 4 ft fabric uses multiple parallel strips, with each internal seam consuming overlap.
Assumptions
- Strips run parallel to the entered bed length.
- Staple count is a geometric planning estimate from entered spacing, not a soil-specific fastening specification.

Frequently asked questions
Can I use this under gravel?
The quantity math works for any rectangular coverage area; choose the fabric type and fastening method appropriate to the project.
