What fabric widths should I use?

Common fabric widths are 44–45" (quilting cotton), 54" (decorator fabric), and 58–60" (apparel knits and wovens). Check your fabric bolt label or ask the shop assistant.

Does the calculator account for pattern matching or nap?

No — this tool assumes pieces can be placed freely without directional constraints. For striped, plaid, or napped fabrics, add one extra repeat length per large piece as a manual buffer.

Should I include seam allowance in my piece dimensions?

Enter the finished (sewn) dimensions and let the calculator add seam allowance automatically, OR enter the cut dimensions and set seam allowance to 0.

Why is a 10% waste buffer recommended?

Pre-washing causes shrinkage (typically 3–5%), and imperfect cutting wastes small strips. The 10% buffer covers both, so you never come up short.

How accurate is the yardage estimate?

The calculator uses a greedy row-packing algorithm that reflects real cutting layouts. Results are conservative — you may use slightly less in practice if pieces nest efficiently.

Can I calculate yardage in meters instead of yards?

Yes — the results panel shows both yards and meters side by side. Dimensions are entered in inches; 1 yard = 36 inches = 0.9144 meters.
