Estimate only — patterned fabric with repeats needs extra to match the design across seams.

How fabric yardage is calculated

We convert your area to the linear length needed at your fabric's bolt width, add a waste allowance for cutting and seams, then round up to the nearest quarter yard (or 10 cm) — the increment most fabric stores cut to. A patterned fabric with a repeat may need extra length beyond this to line up the design at seams.

Frequently asked questions

It depends on your project's total surface area and your fabric's width — wider bolts need less linear yardage for the same area. Enter your numbers above for an exact figure.

Yes — fabrics with a repeating pattern (like stripes or a large print) often need 10-25% extra beyond a solid fabric so the pattern lines up across seams. Increase the waste allowance above to account for this.
