Thread count is the number of threads in a square inch of fabric. Good cotton sheets usually sit between about 200 and 600. Very high counts are often achieved with thin multi-ply threads and do not mean better sheets. Fiber quality (long-staple cotton, linen), weave (crisp percale or silky sateen) and fit matter more.
Thread count is the most advertised and least useful sheet spec.
What actually matters
| Factor | Why it matters |
|---|---|
| Fiber | Long-staple cotton is softer and stronger |
| Weave | Percale is crisp and cool; sateen is smooth and warmer |
| Thread count | 200 to 600 is a sensible range for cotton |
| Certification | OEKO-TEX or GOTS for tested or organic textiles |
| Fit | Pocket depth must suit your mattress |
Choosing sheets
- Hot sleepers: cotton percale or linen; see how to sleep cooler.
- Smooth feel: cotton sateen.
- Durability: long-staple cotton, single-ply yarns.
- Measure mattress depth before buying fitted sheets.
Care
Wash in warm water, avoid overdrying and skip fabric softener, which can reduce absorbency.
Pair with the right weighted blanket or duvet. Browse bedding.
Common questions
Is 1,000 thread count better?
Not necessarily. Very high counts often use multi-ply yarns, which can make sheets heavier and warmer without better feel or durability.
Does linen have a thread count?
Linen threads are thicker, so counts are low. Linen is judged by weight and quality instead.
Percale or sateen?
Percale feels crisp and cool; sateen feels smooth and slightly warmer.
