PAPER WEIGHTS (GRAMS AND MICRONS)

Paper weight is given as the weight in grams per square metre (gsm). A single square sheet (1m x 1m) of copier paper weighs 80g, (not an A4 sheet which will weigh much less). Thus in many cases paper weight is directly proportional to paper thickness. With this in mind, it is worth noting that some papers, such as the coated papers described above, are usually thinner than the same weight/size sheet of uncoated paper. This is because these papers are denser, e.g. 100 gsm coated is thinner than 100 gsm uncoated. Sometimes paper is given in thickness as opposed to weight and this is becoming more common. The thickness is given in microns, which are thousandths of a mm.
