Thread count in bedding and what the number means

Short answer: Thread count is the number of threads per inch. Up to a point more threads mean a better fabric, but beyond that they only make it heavier.

What the number counts

Thread count counts the threads lengthwise and crosswise in one square inch. A figure around three hundred is good bedding. Below two hundred is thin, and above five hundred rarely gives a noticeable improvement.

Why very high numbers mislead

Some manufacturers count each individual strand in a plied yarn and arrive at very high numbers. The fabric is no better for it, only denser and heavier. Look at fibre type and weave instead. See bamboo bedding.

What matters more

Fibre and weave matter more than the number. Bamboo viscose in sateen feels smooth whatever the thread count, and percale feels cool. See bamboo sheets.

What to look for

Look at weight per square metre, fibre composition and whether it is percale or sateen. Those three things say more than thread count alone. See bamboo fitted sheets.

Frequently asked questions

Is high thread count always more expensive

Often yes, but the price does not always follow a real improvement.

What is a good thread count

Between two hundred and fifty and four hundred covers almost all good bedding.

Is thread count used for knitted fabric too

No. For knits, grams per square metre is used instead.
