In Europe, paper is measured in GSM. This stands for ‘Grams per Square Meter’ and means exactly that ie how many grams a single sheet of paper weighs measuring 1m x 1m.
We offer paper weights of 90, 100 & 120gsm.
A low quality sheet used in photo copiers is often 80gsm. Company letter headed paper would commonly be printed on either 100gsm or 120gsm.
