Understanding GSM
GSM. It may sound like a fancy term, but it’s actually quite simple. GSM stands for grams per square meter and it’s a measure of paper thickness. The higher the GSM, the thicker the paper.
Different printing projects require different paper weights. If you’re printing a brochure that needs to feel sturdy, you’ll want to use a paper with a higher GSM. Meanwhile, if you’re printing a large batch of flyers, a thinner paper with a lower GSM may be more cost-effective.
Top tip: A good way to decipher what you’re after is thinking about your printer paper at home. A standard piece of copy paper is usually around 80 GSM.
