Thread Count Explained: 200, 300 & 400 TC, GSM and Weave
“1000 thread count!” sounds impressive on a label — but does it actually mean a better sheet? Short answer: not always. Let’s decode the numbers so you never overpay for a big one again.
The 10-second version
- Thread count (TC) = threads per square inch. Higher can mean smoother — up to a point.
- Sweet spot: 200–400 TC. Beyond that, numbers are often inflated.
- GSM = fabric weight (great for judging dohars). Weave = the feel (crisp vs silky).
- The real secret to a luxe sheet isn’t the number — it’s long-staple cotton.
First: what is thread count?
Thread count is simply the number of threads packed into one square inch — the lengthwise ones (warp) plus the crosswise ones (weft). More threads can mean a denser, smoother sheet. But — and this is the bit labels don’t tell you — the quality of the yarn matters just as much as the count.
200 vs 300 vs 400 TC: what you actually feel
| Thread count | How it feels | Good for |
|---|---|---|
| 180–200 TC | Crisp, cool, breathable, hard-wearing | Everyday use, hot weather |
| 250–300 TC | Noticeably softer & smoother, still breathable | The all-round sweet spot |
| 400 TC | Premium, silky, often a sateen sheen | A little luxury |
The “1000 thread count” myth 🤯
Here’s the trick: many sky-high counts (600, 800, “1000+”) are reached by twisting several thin, low-grade plies together and counting each ply. The headline number balloons; the cloth doesn’t actually get finer.
A well-made single-ply 300–400 TC sheet usually beats an inflated “1000 TC” one. Trust the feel, not the hype.
GSM: the number that matters for weight
GSM (grams per square metre) measures weight, not thread density. It’s the most useful number for dohars and heavier bedding: higher GSM = more substantial and a touch warmer; lower GSM = lighter and airier. For sheets, it tells you how dense the fabric feels — e.g. a 120 GSM cotton sheet is soft yet sturdy for daily use.
Weave: crisp percale or silky sateen?
Two sheets with the same thread count can feel totally different — that’s the weave talking:
- Percale: simple, tight, matte and breathable — that cool, hotel-fresh feel.
- Sateen: more threads float on top for a soft, silky hand and gentle shine. This is what gives glace cotton its smoothness.
The real luxury secret: staple length
The biggest driver of how premium a sheet feels is staple length — how long the cotton fibres are. Longer fibres spin into finer, stronger, smoother yarns that pill less and last longer. That’s why an extra-long staple (ELS) cotton at 300 TC can out-feel an ordinary cotton at 500 TC.
So what should you buy?
Don’t chase one number. Look for the combo: good long-staple cotton + 200–400 TC + a weave you like + a finish you can feel. An honest spec from a trustworthy seller beats a flashy figure every time.
Quick questions, quick answers
Is a higher thread count always better?
Nope. Past ~400 TC the gains are small, and many high numbers are inflated by counting multiple thin plies. Yarn quality and staple length matter more.
What thread count is best in India?
200–300 TC pure cotton is breathable and ideal for the climate. Go 300–400 TC (often sateen) when you want a softer, premium feel.
Is 400 thread count good?
Yes — a genuine single-ply 400 TC long-staple cotton sheet is soft, smooth and durable. A great premium everyday choice.
What does GSM mean on bedding?
Grams per square metre — the fabric’s weight. Higher = denser and warmer; lower = lighter. Especially handy for judging dohars.
Percale or sateen?
Percale is crisp, matte and cooler; sateen is softer with a subtle sheen. Same thread count can feel very different depending on which you choose.
