Where 89 gsm comes from
An American basis weight is the weight of 500 sheets at that grade's basis size. For text / book that size is 25 × 38 inches, so:
500 sheets × 25 × 38 in = 475,000 in² = 306.5 m²
60 lb = 27,216 g
27,216 g ÷ 306.5 m² = 89 g/m²The same number, a different paper
60 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 | 60 lb is | vs text |
|---|---|---|---|
| Text / Book | 25 × 38 in | 89 gsm | — |
| Bond / Writing | 17 × 22 in | 226 gsm | 2.54× |
| Cover | 20 × 26 in | 162 gsm | 1.83× |
| Index | 25.5 × 30.5 in | 108 gsm | 1.22× |
| Tag | 24 × 36 in | 98 gsm | 1.10× |
| Bristol | 22.5 × 28.5 in | 132 gsm | 1.48× |
This is the reason to ask for gsm. One number, no grade, no ambiguity — 89 gsm is 89 gsm whoever is printing it.
