Number English: counting 840-yard hanks per pound
Cotton count — Ne, or Number English — is a measure of linear density in the indirect family: the number of hanks (840 yards, or 770 m, each) of yarn that together weigh one pound (0.45 kg). Under this system the higher the number, the finer the yarn. In the United States, cotton counts between 1 and 20 are called coarse counts; a regular single-knit t-shirt typically falls between 20 and 40 count, and fine bed sheets usually run from 40 to 80 count. This page explains the system — and stresses the point its name invites confusing: cotton count is not the same thing as thread count.
For the complete picture of how cotton yarn is made and specified, see the Apparel Search Yarn & Spinning Guide — including a yarn count systems guide that converts Ne to tex, Nm and denier, plus guides to spinning methods, twist, and carded and combed preparation.

Note: the Cotton Count is NOT the same thing as thread count.
Ne (Number English) or cotton count is another measure of linear density. It is the number of hanks (840 yd or 770 m) of skein material that weigh 1 pound (0.45 kg). Under this system, the higher the number, the finer the yarn. In the United States cotton counts between 1 and 20 are referred to as coarse counts. A regular single-knit T-shirt can be between 20 and 40 count; fine bed sheets are usually in the range of 40 to 80 count. The number is now widely used in the staple fiber industry.
Hank: a length of 7 leas or 840 yards (770 m)
One lea – 120 yards (110 m)

The two terms sound like cousins and are constantly confused, but they measure different things at different stages. Cotton count describes a yarn — one strand's fineness, before any weaving happens. Thread count describes a finished fabric — how many warp and weft threads occupy a square inch of it. A sheet's thread count is built from yarns that each carry their own cotton count, and a high thread count woven from coarse, low-count yarns is a very different product from the same thread count in fine yarns. Buyers who keep the two apart can read a specification properly; shoppers who merge them end up comparing numbers that were never measuring the same thing.
The ranges on this page make the scale tangible. Coarse counts under 20 Ne become denim warps, canvas and heavy workwear yarns; the 20 to 40 band knits the everyday t-shirt, where softness and durability balance; counts from 40 upward weave the finer shirtings and bed sheets, and the finest counts serve lawn, voile and luxury sheeting. Because the hank behind the system — 840 yards — is itself defined as seven leas of 120 yards, older records sometimes quote leas, and the hank definition linked in this section untangles the small units bundled inside the big one.
Cotton count, or Number English (Ne), is the number of 840-yard hanks of yarn that weigh one pound. The higher the number, the finer the yarn.
No. Cotton count measures the fineness of a single yarn; thread count measures how many warp and weft threads are woven into a square inch of finished fabric.
A regular single-knit t-shirt usually falls between 20 and 40 count; counts 1 to 20 are considered coarse, and fine bed sheets typically run 40 to 80 count.
