Thread Count vs GSM: How to Judge Bedsheet Quality in India (2026)
Two numbers get thrown around when you shop for bedsheets: thread count and GSM. Both claim to measure quality, both are easy to inflate on a product page, and neither tells the whole story on its own. This guide explains what each number really means, when to trust it, and how to combine it with fabric and weave to actually pick a sheet you'll love sleeping on.
What thread count actually measures
Thread count is the number of threads woven into one square inch of fabric — vertical (warp) plus horizontal (weft). Higher counts can mean a finer, smoother sheet, but only up to a point. Beyond roughly 400, brands often use multi-ply yarns to inflate the number, so a '1000 thread count' sheet can feel worse than an honest 300. For everyday cotton bedsheets, a real 200–400 thread count is the sweet spot for softness, breathability and durability.
What GSM measures (and why bedding uses it less)
GSM (grams per square metre) measures the weight, and therefore the density, of a fabric. It's the go-to metric for towels and winter bedding like dohars and blankets, where heavier usually means warmer and more substantial. For flat cotton bedsheets it matters less than weave and fibre quality, but it's a useful sanity check: an extremely light sheet may feel thin and see-through, while a very heavy one can sleep hot in Indian summers.
Thread count vs GSM — quick comparison
What matters more than either number
The fibre and the weave decide how a sheet feels far more than a headline number. Long-staple combed cotton with a percale (crisp, breathable) or sateen (smooth, lustrous) weave will outperform a high-thread-count sheet made from cheap short-staple yarn. When in doubt, prioritise honest fabric descriptions over big numbers — our printed cotton bedsheets are woven for a soft, breathable feel that suits India's climate year-round.
- Fibre: long-staple / combed cotton lasts longer and softens with washing
- Weave: percale for cool & crisp, sateen for silky & warm
- Single-ply yarn beats multi-ply inflated thread counts
- Weight (GSM) suited to your season and room temperature
- Honest sizing so the fitted sheet actually grips your mattress

The verdict
Don't buy on a single number. Use thread count (aim for an honest 200–400) as a softness guide for cotton sheets, use GSM to match weight to your season, and let fibre and weave be the deciding factors. Get those right and the sheet will feel great regardless of the marketing on the label.
