L = ceil(n ÷ floor(W ÷ w)) × l × (1 + ease)= 3
Note
Simplified model: these are standard craft estimates based on rectangular layouts, quoted gauge and nominal densities. Real fabric nap, directional prints, shrinkage, pattern matching, yarn lots and supplier SAP values vary, so always make a swatch or test piece and buy a little extra.

How do I know how much fabric a pattern actually needs?+
Fabric yardage depends on your size, the garment's view or view length, and the fabric width printed on the pattern envelope. This calculator scales the envelope's yardage chart to your fabric width and size, since patterns are cut for standard bolt widths (usually 45in or 60in).
Why does a wider fabric need less yardage?+
Pattern pieces are laid out across the fabric width, so a wider bolt fits more pieces side by side and needs less length. Going from 45in to 60in fabric can cut the required yardage noticeably, especially for pieces wider than half the narrow width.
Should I add extra for prints or napped fabric?+
Yes. Directional prints, plaids that need matching, and napped fabrics like velvet require all pieces cut in the same direction, which wastes fabric compared to a plain weave. Add 10-20% beyond the calculated amount for these fabrics.
What does the result actually give me, yards or meters?+
The result is a length of fabric at the width you specified, rounded up to a practical cutting increment (often the nearest 1/8 or 1/4 yard). Always round up rather than down, since fabric stores generally do not accept returns on cut yardage.
Why did the calculator suggest more than the envelope's own chart?+
The envelope chart assumes a particular layout efficiency; if your fabric width isn't one of the standard columns, the calculator interpolates and adds a small safety margin. Extra length also covers shrinkage from pre-washing and any pattern-matching at seams.
