Fabric Calculator: Sew & Quilt

Fabric Calculator and Sewing Calculator — the easiest way to know exactly how much fabric your next project needs. Dressmaker, quilter, tailor or weekend crafter — enter your project dimensions and get instant fabric yardage in seconds. Never overbuy or underbuy fabric at the store again.

Whether you're cutting a dress pattern, backing a quilt, hemming curtains or upholstering a chair — this fabric yardage calculator handles yards, meters, inches, feet and centimetres with one tap. Built for the real sewing room, not a spreadsheet.

★ EVERYTHING THIS FABRIC CALCULATOR DOES ★

📏 FABRIC YARDAGE CALCULATOR
Enter your project length, width and fabric width — get the exact yardage (or metres) you need to buy. Supports standard 44", 54", 58" and 60" bolt widths, plus any custom width.

✂️ SEWING CALCULATOR
Plan dresses, skirts, tops, pants, jackets and home-decor projects with confidence. Adds seam allowance and shrinkage margin automatically so you don't come up short at the cutting table.

🧵 QUILT CALCULATOR
Calculate yardage for quilt top, backing, binding and batting in one flow. Supports twin, full, queen and king sizes, plus fully custom dimensions. Handles both pieced backings and wide-back bolts.

🪟 CURTAIN & DRAPE CALCULATOR
Enter window width, drop, fullness ratio and pattern repeat — get yardage for curtains, drapes, valances and Roman blinds. Perfect for home sewers and interior-decor projects.

🔄 UNIT CONVERTER
Instantly convert yards ↔ metres, inches ↔ centimetres, feet ↔ inches, metres ↔ feet. Essential when your pattern is in one unit and the fabric shop quotes another.

📐 SEAM ALLOWANCE & SHRINKAGE
Toggle seam allowance (¼", ⅜", ½", ⅝", 1") per project. Add a shrinkage percentage for cotton, linen, wool or denim so your finished piece fits after the first wash.
