Result
120 gsm ≈ 81.08 lb (text)
GSM is an absolute weight per square metre, but the "lb" figure depends on the paper type, because each has a different basis size. That is why the same gsm gives different lb figures for text and cover stock.
- Pounds (lb)text stock basis
- 81.08 lb
- GSM
- 120 g/m²
What this cannot tell you
- GSM is absolute; the pound figure depends on paper type, so pick the right stock or the lb value will be wrong.

How this calculation works
GSM is grams per square metre — an absolute measure. US pound weight is based on the weight of a ream at that paper’s basis size, which differs by type, so the same gsm converts to different pounds for text versus cover stock.
What the results mean
- Paper type matters
- 120 gsm is about 32 lb text but 44 lb cover — same paper weight, different pound number, because the basis size differs.
Frequently asked questions
Why does the same gsm give different pounds?
Because US paper weights are based on the weight of 500 sheets at each paper type’s basis size, and those basis sizes differ. GSM sidesteps all that by measuring weight per square metre directly, which is why the rest of the world uses it. Pick the correct stock type here so the conversion matches your paper.
