Free Sewing & Quilting Calculators

Buying too little fabric means a trip back to the store and a dye lot mismatch. Buying too much wastes money. These calculators handle fabric yardage, seam allowances, bias tape cuts, button placement, elastic sizing, quilt dimensions, binding strips, and embroidery thread estimates — so every cut is right the first time.
