Frequently Asked Questions
What is GSM?
GSM (grams per square meter) is the international standard for paper weight. It measures the actual weight of one square meter of paper. Higher GSM means thicker, heavier paper. Standard copy paper is 75-80 GSM.
What is the difference between Bond and Text weight?
Bond and Text weights use different 'basis sizes' for measurement. 20 lb Bond = 50 lb Text = 75 GSM. The same paper can have different numbers depending on the US weight system used.
What GSM is best for business cards?
Business cards are typically 300-350 GSM (110-130 lb cover). Premium cards use 400+ GSM. Anything below 250 GSM feels flimsy for a business card.
