Cotton is graded in the following manner:
Possible to spin
Low grade cotton (short stapled cotton) - Medium counts-40s to 60s
coarser counts-below 40s
Fibre property requirements to spin various counts of yarn.
| 10s | 20s | 40s | 60s | 80s | |
| Fibre length mean length mm Effective length (mm) | 17 24 | 20 28 | 24 32 | 27 34 | 29 37 |
| Short fibre % | 16 | 16 | 18 | 20 | 22 |
| Micronaire value | 5.2 | 4.4 | 4 | 3.7 | 3.5 |
| Maturity fibre % | 60 | 60 | 60 | 60 | 60 |
| Bundle fibre strength (grams/tex)3mm gauge | 19 | 21 | 24 | 27 | 29 |
