Thread count is the number everyone quotes and almost nobody understands. A "1000 thread count" sheet sounds like luxury. Often it's just marketing math, extra plies twisted together to inflate the number without improving how the fabric actually feels.
Here's what actually decides whether a bedsheet feels good against your skin, breathes properly through the night, and holds up wash after wash.
Staple length matters more than the number on the label
Cotton fibre length, or staple length, is the real starting point. Long-staple cotton (sometimes called extra-long staple, or ELS) produces finer, stronger yarn with fewer loose fibre ends. That's what gives a sheet its smooth, almost silky hand feel, and why it softens with every wash instead of pilling.
Short-staple cotton needs more twisting to hold together, which is where inflated thread counts usually come from. Two 500-thread-count plies get sold as "1000 thread count," but the yarn itself is weaker and rougher than a genuine long-staple sheet at half that number.
Weave changes how a sheet feels, not just how it looks
The two most common weaves are percale and sateen.
Percale is woven in a simple over-under pattern. It comes out crisp, matte, and cool to the touch, the kind of sheet that suits warmer months and hot sleepers.
Sateen uses a weave where more threads pass over than under, which catches light differently and gives the fabric a soft sheen. It drapes more, feels silkier, and runs slightly warmer than percale, better suited to cooler nights or anyone who wants that hotel-bed feel.
Neither is objectively better. It depends on how you sleep and what climate you're sleeping in.
What to actually check before buying
Skip the thread count arms race and look for:
- Staple length, ideally long-staple or extra-long-staple cotton, listed clearly by the brand.
- Weave type, percale or sateen, so you know what you're getting before it arrives.
- Certification, something like OEKO-TEX Standard 100, which tests the finished fabric against harmful substances rather than just raw material claims.
- Pre-washed finishing, which softens the sheet before it reaches you instead of leaving that stiff, straight-off-the-shelf feel for the first ten washes.
A thread count of 300 to 400 in genuine long-staple cotton will almost always outperform a "1000 thread count" sheet made from shorter fibres. The number on the label is easy to inflate. The feel isn't.
Our approach
Every Loom & Lay sheet set is woven from 100% long-staple cotton, pre-washed for softness before it ships, and OEKO-TEX Standard 100 certified. We'd rather you judge us by how the sheet feels on night one than by a number on the packaging.
