150 gsm paper

Q: What is 150 gsm in lb?

It depends which grade — that is the whole difficulty. 40 lb bond, 101 lb text, 55 lb cover. American basis weights are not comparable between grades, so a pound figure means nothing without the grade beside it.

Q: How thick is 150 gsm paper?

Roughly 0.188 mm for an uncoated sheet — about 0.188 mm — though thickness depends on how the paper was made as much as on its weight. A bulky uncoated stock and a compressed glossy one at the same gsm can differ by half again.

What 150 gsm is for

Poster and flyer weight. It holds its shape on a wall without curling and takes heavy ink coverage without cockling, which lighter stock does not.

150 gsm in American basis weights

One metric weight becomes six different pound figures, because each American grade is weighed at a different sheet size. None of them is more correct than the others — but some are outside the range that grade is actually sold in, and those are marked.
