Thread count is the number of threads woven into a square inch of fabric. More threads generally means a smoother, denser, longer-lasting sheet — up to a point.
The honest range
**Under 150 TC** is where you feel it. Cheap poly-cotton at 120-144 TC is thin, it pills after a term of hot washes, and it does not breathe. This is the single most common false economy in a starter pack.
**180-200 TC cotton** is the sweet spot for halls. It feels good, survives a laundry room, and costs very little more than the bottom tier. If you upgrade one thing in a budget kit, upgrade this.
**300 TC and up** is genuinely nicer, and you will notice it on the first night. But the jump from 200 to 300 is a smaller improvement than the jump from 144 to 200, for more money.
**Anything advertised above 800 TC** at student prices is almost always multi-ply counting — several thin threads twisted together and counted separately. Ignore the number and read the material instead.
Material matters more than the number
A 200 TC 100% cotton percale sheet beats a 400 TC poly-cotton one. Percale is crisp and cool; sateen is smoother and warmer. Egyptian cotton uses longer fibres, so it is softer and lasts longer — it is the only "premium" bedding claim that reliably means something.
What to check on the pack
- Is the stated thread count for the duvet cover only, or the sheets too?
- Is a fitted sheet included, or just the cover and pillowcase?
- Is there a mattress protector? Halls mattresses are communal. You want one.
