textile.fabric-shrinkage Calculator
Calculates how much fabric to buy pre-wash to end up with the required post-wash dimensions, given shrinkage percentage in warp and weft directions. Pre-washing fabric before cutting is standard practice — this prevents finished garments from being too small after laundering.
Inputs
Original Length Cm
Linear measurement. Ensure consistent units: 1 m = 1,000 mm = 3.281 ft.
Washed Length Cm
Linear measurement. Ensure consistent units: 1 m = 1,000 mm = 3.281 ft.
Original Width Cm
Horizontal extent perpendicular to the length.
Washed Width Cm
Horizontal extent perpendicular to the length.
Results
lengthwise shrinkage (%)
The computed linear length.
widthwise shrinkage (%)
The computed width.
area loss (%)
The computed two-dimensional surface area.
AATCC standard
The value at the specified point or condition.
pre-shrink allowance
Sample size or count used in the calculation.
dimensional stability
Measure of how robust the system, structure, or process is to perturbations. Low stability means small changes can cause large deviations.
