Clothes shrink mainly because of heat, agitation, and tension during washing and drying, with natural fibers such as wool and cotton often being especially sensitive. Prevention starts by reading the care label before the first wash and using the gentlest cycle that still cleans the garment.
Follow the care-label temperature
Do not assume every cotton garment tolerates hot water or that a synthetic blend cannot shrink. The care label reflects the fabric, construction, and finish, not just the fiber name.
Reduce agitation for wool and delicate fabrics
Wool can felt when heat, moisture, and friction act together. Use a wool or hand-wash cycle when the label calls for it and avoid wringing the garment to remove water.
Control dryer heat
Many garments shrink more in the dryer than in the washer because they reach higher temperatures while tumbling. Use low heat or air drying when the label recommends it, and remove clothes when dry rather than continuing the cycle.
Do not overload the washer
An overpacked load increases rubbing and prevents water and detergent from circulating properly. Leave enough space for the washer design and separate very heavy items from delicate fabrics.
