Why Do My Clothes Shrink in the Dryer?

Short Answer

Clothes shrink in the dryer because heat causes fibers to tighten and contract, especially in cotton, wool, and natural fabrics. High heat and over-drying make shrinking worse.


Why Shrinking Happens

Natural fibers are stretched during manufacturing. Heat and agitation allow them to relax back to their original size, which makes clothes smaller.

Once shrinkage happens, it’s usually permanent.


Fabrics That Shrink Most

Cotton
Shrinks easily in high heat.

Wool
Shrinks quickly with heat and agitation.

Rayon
Shrinks when wet and heated.

Linen
Shrinks without gentle care.


How to Prevent Shrinking

  • Wash in cold water
  • Use low or no heat to dry
  • Remove clothes while slightly damp
  • Air dry delicate items
  • Check care labels before washing

Quick FAQ

Can shrunken clothes be fixed?
Sometimes stretching while wet helps, but results vary.

Does air drying prevent shrinkage?
Yes. It’s the safest method.

Is shrinking a defect?
No. It’s a natural fiber reaction.


Summary

Clothes shrink mainly because of heat. Lower temperatures and air drying prevent most shrinkage problems.
