Paper Stock

Paper Weight and Paper Conversion

Converting GMS to points and pounds and vice versa.

Paper conversion.

A paper weight chart to compare grams per square meter to points and pounds. This is for book printing stock that we use in Asia, and the comparison to USA paper weights. If printing a book with Star Print Brokers, we will automatically select or suggest the appropriate stock for your book. The paper conversion and paper weight information follows …

Grams per square meter — converting to points and pounds.

Text stock versus cover stock: The coated stock (first section below) is for text stock, not cover stock. For instance, business cards are most often printed on a paper weight of 80 lb cover stock. If they print on 80 lb text stock, they would be very thin business cards! 80 lb text and 80 lb cover paper weight stock are different thicknesses. Also see “Calculating paper conversion” in the right column.

Paper conversion. Paper weight chart for grams per square meter (gsm) to points and pounds. USA versus Asia and Europe.

Calculating paper conversion for paper weight.

Do you convert USA lbs to the nearest Asia or European gsm equivalent? Use these formulas:

Text stock, paper conversion: multiply lbs by 1.5 to arrive at the gsm

Cover stock, paper conversion: multiply lbs by 2.70 to arrive at the gsm

Examples:

Be aware that the paper weight calculation may be approximate.

lbs to gsm: 60 lb text stock multiplied by 1.5 = 90 gsm. However 90 gsm is not standard, so the closest paper conversion is 100 grams per square meter stock.

gsm to lbs: 120 gsm text stock divided by 1.5 = 80 lbs. 120 grams per square meter paper conversion translates to 80 lb stock.
