Sewing Tools

Calculators for fabric shrinkage and sewing project planning.

Cotton typically shrinks 2-5%. Calculate exact fabric loss for quilting cotton, voile, or canvas to ensure you buy enough yardage.

Linen fibers relax significantly when washed. Expect 5-10% shrinkage loss. Plan your yardage accordingly to avoid shortage.

Rayon is notorious for shrinking. Calculate the high loss rate (often 10%+) before cutting your pattern.

Wool can felt and shrink dramatically if agitated. Use this to calculate loss for felting projects or pre-treatment.

Raw denim and heavy cotton twills often shrink significantly in length. Expect 10-12% shrinkage for unsanforized denim.

Silk, especially Crepe de Chine, can shrink 5-8% when washed. Dry cleaning minimizes this, but hand washing changes the texture.

Flannel is loosely woven and brushed, leading to high shrinkage rates (often 8-10% or more). Buy extra yardage.

Polyester is very stable. Shrinkage is usually minimal (under 2%), but high heat drying can cause permanent creases or damage.
