GSM is an acronym standing for ‘Grams per Square Meter’. Quite simply, it allows print buyers and print suppliers to know exactly about the quality of paper that is being ordered. The higher the GSM number, the heavier the paper. If you’re buying print then make sure you know what you’re talking about. Being specific about the GSM you’re after can make all the difference and you’re likely to be taken more seriously by a printer if you ask for a specific GSM rather than just asking for thick or thin paper.

100gsm: This is the weight of most household printer paper. Silky paper, Best for Resume Printing, Important Document Printing and Premium Book Printing.
