Paper weights The weight of a piece of paper is defined by the weight in grams per square meter (gsm). Alternately, weight may be determined by what a set number of sheets would weigh in pounds. Regular bond paper that one might use in a desktop printer is generally 90 gsm or 20-24 lb.
A general breakdown of paper weights by gsm:
35-55 gsm: newspaper
130-170 gsm: posters
350 gsm: business cards
