What is Paper GSM or gm/2? Grams Per Square Meter Banner

What is GSM? GSM, or gm/2 stands for ‘Grams Per Square Meter’.

This is the paper’s weight measurement, meaning a thicker paper will have a higher GSM. A thicker gm/2 typically brings a more prestigious feel to media and increases its longevity. The heavier the paper, the higher the number of grams per square metre – and, generally, the higher paper quality.  

Examples Of Suitable GSM

Office Paper

Internal office paper is typically 80 GSM which is rather thin. Usually, a paper weight between 100/120 GSM is best for documents and letters.

Flyers and Leaflets are most often made using 160/200 GSM media. They still have the quality feel of thick paper. However, it is far cheaper to purchase and easier to fold into pockets and bags.

Cardstock

Greetings Cards typically opt for a higher thickness of around 300 for a more premium feel, this thickness can also hold its own weight allowing it to be propped open. Business cards are usually between 350 and 400 gsm or g/m2 and can often be laminated to produce an even better look and feel.
