Landscape Fabric Calculator
Estimate how many rolls of landscape fabric you need to cover a bed. Coverage, rolls, and cost.
Inputs
Fabric lays flat under the material.
6″ is standard; 12″ for driveways.

- Strips (across width)
- 6
- Roll size
- 300 sq ft/roll
Installation notes
- Overlap adjacent strips by at least 6″ and pin every 12″ with landscape staples.
- Under gravel driveways, choose heavy non-woven fabric; under decorative rock, woven fabric lasts longer.
- Full-wrap ("burrito wrap") is the pro method for French drains — fabric encloses the drain rock to prevent silt clogging.
Professional guidance
When to use landscape fabric
Under decorative rock, gravel paths, and low-maintenance beds. Skip it in perennial beds where you'll dig regularly.
Recommended overlap
Overlap edges by 6 inches and pin every 12 inches with landscape staples.
Pro tip
Woven fabric goes under rock; heavier non-woven goes under gravel driveways. Skip the cheap perforated plastic — it fails in a season.
Common mistakes
Putting fabric under mulch in planting beds. Mulch breaks down into soil and grows weeds on top of the fabric.
Material assumptions
- Standard rolls: 3 ft × 100 ft (300 sq ft) or 4 ft × 50 ft (200 sq ft).
- Overlap seams by 6 inches — the extra coverage is why waste is 10%+.
- Woven fabric lasts longer than non-woven under rock.
