The English system of numbering Card Clothing is now generally used by Cotton Mills. We give below the numbers and points per square foot:
| Numbers | Pts. per Square Foot |
| 80s | 57,600 |
| 90s | 64,800 |
| 100s | 72,000 |
| 110s | 79,200 |
| 120s | 86,400 |
| 130s | 93,600 |
The following numbers are generally used for Cylinders: Coarse, heavy work, 80s and 90s; medium to fine work, 100s and 110s; fine work, 120s and 130s.
Doffers are usually 10 numbers higher or finer than Cylinders.
There is considerable variation in the Clothing used for Tops. Some prefer thinner set than the Cylinders, others about the same as the Cylinders, and a few the same numbers as the Doffers.
