Thread count is a marketing number — here's what to look at instead
The count is real; the inflation is the trick. Four other variables predict how a sheet sleeps — and every one of them is harder to fake.

How does a fabric hit 1200 threads?
By counting differently, not weaving differently. Thread count is yarns per square inch, and there's a standardised ASTM test method for it. But weave a yarn spun from three thin plies and count each ply separately, and an honest three hundred becomes a label nine hundred — denser and heavier, not finer.
That's why the four-figure sets so often disappoint: the number went up; the cotton didn't change.
What predicts quality better?
Fibre first — long-staple cotton or linen beats mystery cotton at any count. Weave second — crisp percale versus smooth sateen changes the feel of identical yarn completely. Weight third — fabric that feels substantial without being dense as canvas. And returns policy last, because it prices the seller's own confidence: a brand offering a hundred nights with paid return shipping is betting you'll keep the sheets.
Most well-made cotton lives between two and four hundred; the set we currently rank first sits at three hundred, which is part of why we trust its spec sheet — it's a number chosen by weavers, not marketers.
