Shrinkage  Calculator
Dimensions (in or cm) Unwashed Washed
To calculate shrinkage, cut your fabric into a square, record the measurements before washing in the column marked Unwashed. 

Wash & dry your fabrics using the product's care instructions and record measurements. 

Repeat the wash & dry until the measurement stays constant (no change),  This is typically 1 wash for synthetics, 2-3 for natural or regenerated fibers.

Record the final length and width in the calculator.
