Where 163 gsm comes from
An American basis weight is the weight of 500 sheets at that grade's basis size. For tag that size is 24 × 36 inches, so:
500 sheets × 24 × 36 in = 432,000 in² = 278.7 m²
100 lb = 45,359 g
45,359 g ÷ 278.7 m² = 163 g/m²The same number, a different paper
100 lb is not one weight. Because every grade is weighed at its own sheet size, the same pound figure describes papers that are nothing alike:
| Grade | Basis size | 100 lb is | vs tag |
|---|---|---|---|
| Tag | 24 × 36 in | 163 gsm | — |
| Bond / Writing | 17 × 22 in | 376 gsm | 2.31× |
| Text / Book | 25 × 38 in | 148 gsm | 0.91× |
| Cover | 20 × 26 in | 270 gsm | 1.66× |
| Index | 25.5 × 30.5 in | 181 gsm | 1.11× |
| Bristol | 22.5 × 28.5 in | 219 gsm | 1.35× |
This is the reason to ask for gsm. One number, no grade, no ambiguity — 163 gsm is 163 gsm whoever is printing it.
