Shrinkage is not determined by fiber name alone
Textile dimensional change depends on construction and processing as well as laundering conditions. Two cotton garments, for example, can behave differently because their fabrics and finishes are different.
Respect temperature and drying limits
Stay within the garment care label for wash temperature and drying. Repeated high heat or mechanical action can be a poor choice for fit-sensitive items when the label specifies a lower-heat or non-tumble method.
Handle wool and knitwear carefully
Wool can felt or distort under unsuitable combinations of moisture, heat and agitation. Washable wool should be cleaned only by the method allowed on its label, and shape-sensitive knitwear may need flat drying.
Check fit before repeating a harsh process
If an item is especially fit-sensitive, inspect it after laundering and before repeated high-heat drying. A generic fiber profile cannot guarantee dimensional stability for a finished garment.
Separate shrink risk from cleaning intensity
More soil does not automatically justify more heat. Pretreat compatible stains, use a suitable cycle and stay within the care-label temperature. For shrink-prone items, lower heat or air drying may reduce exposure to one of the main risk factors.
Use the drying method as a deliberate choice
The Drying Method Finder adds item type and heat sensitivity to the decision instead of treating every dryer-safe garment the same.
Shrinkage risk is a system of fiber, construction, heat and agitation
There is no universal cold-water guarantee and no single dryer rule for every garment.
The care label is the best item-specific limit
Use the listed wash temperature, cycle and drying method as the main boundary.
Avoid unnecessary heat exposure
Hot washing, high dryer heat and over-drying can increase risk for many cotton, wool and regenerated-cellulose garments.
Reshape items that are vulnerable while damp
Knits and lightweight garments may retain shape better when smoothed or laid out according to their instructions.
Garment care labels, appliance manuals and laundry-product directions can be more specific than a general guide. Use them when they set a tighter limit.
