Hotel linen specs explained: sizing, fabric, and wash performance

18 July 2026·2 min read·Buyer Guide

Linen specifications intimidate more buyers than they should. The vocabulary — TC, GSM, sateen, percale, combed, carded — sounds technical, but the underlying questions are ordinary: what size, what material, how is it built, and how will it behave after fifty washes? This guide walks through the pieces in plain language.

Sizing: the specification that fails silently

Size problems rarely announce themselves at delivery. They appear as sheets that untuck by morning, duvet covers that balloon or strangle their fills, and housekeeping time lost to fighting the bed. Hotel sizing needs to account for mattress height, tuck depth, and shrinkage allowance — which is why finished-size-after-first-wash is the number that matters, not the size on the cutting table.

Fabric: composition before numbers

Cotton, poly-cotton blends, and their proportions shape feel, breathability, drying time, and pressing behaviour. Pure cotton breathes and feels premium but asks more of the laundry. Blends dry faster, crease less, and survive aggressive commercial washing — at some cost to feel. Neither is “better”; they serve different property standards and laundering setups. Only after composition is settled do numbers like thread count add useful precision.

Construction: where durability actually comes from

Two fabrics with identical composition can behave very differently depending on weave and construction. Percale weaves feel crisp and matte; sateen weaves feel smoother with a slight sheen but can snag more readily. Stitching quality, hems, and seam construction decide whether the product’s edges outlive its fabric. Construction is the least discussed and most consequential part of most specifications.

Wash performance: the specification’s exam

Everything above is graded by the laundry. Shrinkage, colour retention on whites, pilling, and dimensional stability across repeated industrial cycles are what separate hotel-grade linen from retail linen that looked identical in the showroom. A supplier who asks detailed questions about your laundering is not being difficult — they are specifying for the exam your linen will actually sit.

Reading a spec sheet: the questions that matter

  • Are sizes stated as finished dimensions, with shrinkage accounted for?
  • Is fabric composition explicit, not just a fabric name?
  • Is the weave stated, and does it match the feel the property wants?
  • What laundering assumptions is the specification built on?
  • What happens at reorder — is this spec documented and repeatable?

Final thought

A good specification is not the most impressive one — it is the one that matches your rooms, your laundry, and your reorder rhythm, written down clearly enough that the next batch can be held to it. Buyers who understand that spend less, argue less, and replace linen less often.

Common questions on this topic

What does “finished size” mean in a linen specification?

The dimensions after production and initial shrinkage — effectively the size the property will actually live with. Specifications quoted as cut sizes without shrinkage allowance routinely produce undersized linen in service.

Is pure cotton always the premium choice for hotels?

It is premium in feel, but not automatically right. Blends can serve high-intensity laundering operations better. The premium choice is the one that matches the property standard and survives the property’s actual wash cycle.

Why do suppliers ask about our laundry before quoting?

Because wash performance is where specifications succeed or fail. Temperature, chemistry, and cycle frequency change which fabric and construction choices make sense. A supplier who quotes without asking is guessing.
