When it comes to purchasing sheets, thread count can be a tricky thing. We've been told for decades that a higher thread count means a better quality sheet, but is that really the truth? The answer is “no” and we're here to explain to you why that is.
Thread count is the number of threads that exist in a square inch of area on a piece of fabric both vertically and horizontally. Anything below 180 thread count is pretty low in quality and isn't something that you want to deal with. Hold a piece of fabric up to the light and if it's around that thread count, you'll be able to see through the tiny holes in it. So, there we have a hard bottom limit for thread count. What about the top limit, though?
The top limit is a little trickier to deal with than the bottom. Dishonest manufacturers will often work in more fibers into a thread to up the thread count of the sheet; double, triple, and even quadruple ply thread sheets exist and this can raise the thread counts up over to 1000 or more.

What you're looking for in real, quality Egyptian cotton sheets is a thread count of between 300 and 800.
