What Is Paper GSM & How to Choose the Right One?
“How many GSM should I choose?”
This is one of the most common questions customers ask when ordering name cards, flyers, brochures, and marketing materials. But what exactly is GSM, and does a higher GSM really mean thicker paper?
Today, we’ll break it down in a simple and practical way, so you’ll always know which paper GSM is right for your next print job.
What Is GSM in Paper?
GSM stands for “Grams per Square Metre” (g/m²).
It is a universal measurement used to identify the weight of paper. The GSM value tells you how much one sheet of paper weighs when cut to 1m × 1m.
In the printing industry, GSM plays a key role in distinguishing paper types:
- Below 200gsm → Usually referred to as paper
- Above 200gsm → Considered card or board
This simple measurement helps printers, designers, and customers understand the feel and durability of the material before printing.
Does GSM Mean Paper Thickness?
Many people assume GSM = thickness, but this is not always true.
Here’s a simple example:
- 350gsm Art Card
- 350gsm Boxboard
Both weigh the same in a 1m² sheet, but the Boxboard usually feels thicker and bulkier.
This is because both materials are made using different pulp structures, coatings, and manufacturing processes, which affect the paper bulk.
So while GSM gives you a good indication of paper weight, it does not guarantee how thick or premium a material feels.
