How to use
- Enter landscape bed or path areas.
- Enter roll width, roll length, overlap, and staple spacing.
- Review roll count and approximate staples before buying.
Input guide
- Roll dimensions are entered in feet.
- Overlap is entered in inches for seams.
- Staple spacing is an approximation; edges and slopes need field adjustment.
Common mistakes
- Ignoring seam overlap.
- Buying fabric without enough staples for edges.
- Using fabric where drainage or plant health would be harmed.
Assumptions and limitations
- No plant health, erosion, drainage, slope, or soil guidance is included.
- Staple count is approximate.
- Area shapes are approximated as rectangles.

Formula
- Fabric area = sum of each area length x width.
- Overlap adds a planning allowance based on overlap width.
- Rolls needed = area with waste / roll coverage, rounded up.
- Staples are approximated from area and spacing.
Example
A 300 sq ft bed with 10% waste and a 3 ft x 100 ft roll needs about 2 rolls. Staple count depends on spacing and edges.
FAQ
Does overlap reduce usable coverage?
Yes. Overlap means some fabric area is doubled at seams, so the calculator adds an allowance.
Is the staple count exact?
No. It is a planning estimate; edges, slopes, seams, and wind exposure can require more staples.
