GSM in short form stands for ‘Grams per Square Meter’.
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.
The most common weight of papers are 130gsm, 150gsm, 170gsm, 300gsm, 350gsm, 400gsm,
The higher the GSM the thicker the paper.
This GSM range covers the paper thickness of most posters you’re likely to find on pub walls etc. Paper with this GSM is sturdy enough to withstand a bit of wear and tear. Its also the thickness of low-cost flyers you might have had posted through your front door by minicab companies and the like.
This GSM is essentially card. It will stand up under its own weight and is most commonly associated with premium flyers and business cards. As well, it is likely to be the stock that high-quality wedding invitations are printed on.
