Enter the area you need to cover and your fabric's bolt width to find how much to buy — rounded up to a real-world cut increment.
Estimate only — patterned fabric with repeats needs extra to match the design across seams.
We convert your area to square inches (or square cm), divide by your fabric's bolt width to get the linear length needed, then add your waste allowance percentage on top. That length is converted to yards (dividing by 36) or meters (dividing by 100), then rounded up to the nearest quarter yard or 10 cm.
Rounding up to a quarter yard or 10 cm matches the increment most fabric stores actually cut to, so the result is a real amount you can buy off a bolt rather than an odd decimal. The waste allowance covers squaring off cut ends and seam allowances — a patterned fabric with a repeat often needs meaningfully more than the 10% default to line the design up across seams.
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.
