Hotel Bedding Specifications: Thread Count vs GSM — What Actually Matters

Thread count and GSM are the two most quoted metrics in hotel textile procurement, but they measure completely different things. This guide explains what each number actually tells you and how to specify bedding that performs.

Every hotel textile buyer encounters two numbers repeatedly: thread count (TC) for sheets and GSM (grams per square metre) for towels. Marketing has inflated both metrics to the point where they often mislead rather than inform. Understanding what each measurement actually indicates — and what it does not — is essential for specifying bedding that delivers genuine guest comfort while surviving commercial laundering.

Thread count is the total number of threads (warp + weft) woven into one square inch of fabric. A 300TC percale sheet has approximately 150 threads running vertically and 150 horizontally.

Consumer marketing has pushed thread counts above 1,000, but the physics of weaving imposes limits:

- Single-ply yarns can realistically achieve 200–400 TC in percale and 300–600 TC in sateen weaves. - Multi-ply yarns (twisting 2–3 thinner threads together) inflate the count artificially. A "1,000 TC" sheet using 2-ply yarn is functionally equivalent to a 500 TC single-ply sheet — but with potentially lower durability.
