If one wants to be very precise and accurate we must send yarn samples to a laboratory to do an analysis, but it involves time and costs money. Thus we want to tell the size of yarn quickly then following method can be used and get the size in less than 5 minutes.
- First keep some yarn in your possession of confirmed sizes, such as 7s,10s,16s,20s, 40s, 45s which are very popular size yarns of 100% cotton or T/C
- Now pull out 1- pcs of yarn from the fabric that you wish to know the size of.
- You twist the yarn in 4 steps as follows and compare the thickness visually and you can determine what size of yarn it is.
- Pull out 10 pcs of warp threads and 10 pcs of weft threads.
- Prepare 10 pcs of yarn that you already know of what size they are.
- Hook up the yarn.
- Now twist the yarn and see that the yarn of unknown size is bigger or smaller than the 10 count yarn.
D. If you find the yarn from the fabric to be smaller than the confirmed size yarn, you use a smaller confirmed size yarn to compare. When the thicknesses the same then you can determine what size of yarn it is. The theory is it is very difficult to tell the size by looking at one piece of yarn but one can do so by looking at 20 pieces together in comparison with another 20 pieces that you know what size they are .

If you want to develop a new fabric, you should not resort to yarn sizes that are not popular (unpopular sizes of yarn if obtainable are usually more expensive). If you need a special size yarn and try to order it from spinner, he may need 100000 pounds or more as a minimum to set up the production for you.
