Paper Weight Calculator
Working across US and metric specs? Convert paper weights between pounds (lbs) and grams per square meter (gsm) in seconds, then check the quick reference chart below for the stocks we run most.
Convert
Pounds and GSM, both directions.
Pounds to GSM
GSM to Pounds
The math is simple: 1 lb Text = 1.48 gsm and 1 lb Cover = 2.708 gsm. Multiply a text weight by 1.48, or a cover weight by 2.708, to get gsm. Divide to go the other way. Stock families overlap, so when a spec matters, our estimators are happy to confirm the exact sheet.
