Recently, I was tempted to buy bed sheets with higher threadcount than I normally buy. I was just curious, that's all. I want to feel it to my skin and see the difference. Plus, they were on sale as it's getting cold and the sheets are for warm season. And I'm still waiting for the warm season to use them. But really, what are threadcounts? Found this in yahoo.com. It looks like those labels are just to use online printing service. I have yet to prove that they are indeed good and last longer.
We searched on "thread count of sheets" and "linens buying guide" and had to rip past dozens of sites trying to sell sheets before we found your answer. Finally, we came to rest upon this definition: thread count is the number of horizontal and vertical threads in one square inch of fabric.
Thread count in sheets can range from 80 to 700, although most stores sell sheets that range from 180 to 320. In general, the higher the thread count, the softer the fabric feels, but that doesn't necessarily mean the sheets will last longer (and sheets with a higher thread count are usually more expensive). One linens department manager says thread counts above 380 are "kind of a farce." Manufacturers twist two threads in a way that lets them double the sheet's thread count.
Recently, many linens manufacturers have touted thread count as the best way to choose a sheet. But others point out that the quality of the fibers and finish are more important to the sheet's comfort and durability. In fact, sheets made of linen, flannel, or jersey (those trendy "T-shirt" sheets) have low thread counts due to the type of fabric. A high thread count would eliminate part of the appeal of these sheets.
According to Consumer Reports, cotton and cotton-blend sheets with a thread count of 180 to 200 stand up to wear and tear and provide satisfactory comfort.
