Measure greenhouse aisles and outdoor walkway lanes accurately. Compare widths, materials, and budget quickly here. Cut less, join smarter, and keep mud outside always.
| Scenario | Inputs | Output (Total Length) |
|---|---|---|
| Greenhouse aisle | Length 12 m, width 0.9 m, ends 0.1 m, waste 8% | ≈ 13.18 m |
| Two garden lanes | Length 18 ft, runners 2, overlap 2 in, waste 10% | ≈ 41.8 ft |
| Segmented path | Segments 3, 2.5, 1.2 m; turns 1; waste 6% | ≈ 7.49 m |
These examples show typical path and aisle use cases.
Runners reduce soil carryover, protect boots, and create stable walking zones around beds, benches, and potting areas. In wet seasons, traction improves and cleanup time drops. In covered houses, runners can lower humidity spikes by limiting puddle spread. Consistent runner coverage also helps define traffic lanes, keeping irrigation lines, seedlings, and drip emitters safer from accidental steps.
Start with the true walk line, not the fence line. Measure along the center of the route, including offsets around raised beds, hose reels, and doors. For broken layouts, sum straight segments between landmarks, then note where joins will land. Record width separately so area and coverage are realistic for carts, wheelbarrows, and harvest totes.
Most installations need extra length beyond the measured run. Add end allowance for trimming, anchoring, and curling edges. When rolls are shorter than your run, joints are required; each joint consumes overlap length and may need fasteners or tape. Turns often require additional slack so the runner can bend without lifting, wrinkling, or creating trip points.
A small waste percentage accounts for cutting errors, frayed ends, and future resizing. Pattern repeat matters for printed surfaces; rounding up to full repeats prevents mismatched motifs at seams. For long aisles, plan cuts near low-visibility zones, and align seams away from splash areas. If you expect seasonal expansion, keep a modest spare strip for patching and replacement.
Review per-runner length first, then multiply for parallel lanes. Compare total length with available roll sizes to estimate how many rolls you must buy and how many joints you will create. Use the area output to evaluate mat weight, drainage backing, and cleaning effort per square meter. If you enter a unit price, the cost field supports budgeting, supplier quotes, and side-by-side material comparison. For gravel beds, choose breathable backing to avoid trapped moisture, and confirm edges will not snag on staples. In food areas, prioritize washable surfaces and schedule daily cleaning intervals based on foot traffic and mud load.
Measure the walking line center-to-center, including bends and offsets around beds or doors. If the path is segmented, add each segment length. Then add end allowance, turn allowance, and any seam overlap you expect.
Ends are commonly trimmed and secured, and some materials curl after unrolling. Adding allowance at both ends reduces the risk of a runner that finishes short and helps account for anchoring methods.
The tool estimates joints as the larger of segment joins or roll joins. Roll joins use ceil(run ÷ roll) − 1. Each joint adds the overlap length you enter, increasing required material.
Use it when the surface has a printed or ribbed repeat and you want seams to align. The calculator rounds the per-runner length up to whole repeats, which helps avoid mismatched patterns at joints.
For straight aisles with simple cuts, 5% to 8% often works. For many turns, uneven edges, or stitched seams, 10% to 12% is safer. Increase waste if you expect installation learning curve.
Yes. Enter the price per selected length unit to estimate total cost for all runners. Keep units consistent across quotes, and use the area output to compare material weight, drainage backing, and cleaning effort.
