Paper weight explained

Paper weight in most parts of the world – (apart from the few countries that will use US paper sizes) – is calculated by grams per square metre.  For example, a single sheet, measuring 1 square meter weighing 80 grams, will be categorised as 80gsm.

(Note: gsm is commonly used rather than g/m2.  This came about because early computer packages were unable to display superscripted characters.)

It is, of course, unlikely that you would have such a thing as one sheet of paper, one meter square, but paper sizes are a fraction of a meter square (AO), and you can therefore work out the real weight of a piece of paper.  This is useful if you are checking postal weights or other delivery costs. Microns measure the thickness of paper and card, i.e. 1000th of a millimetre.  So if you had a pile of 100 sheets of 500 microns cards it would be 50mm (5cm high). A dense material may not be very thick for its weight but a small pile of it will be quite heavy compared with a less dense material.  The paper described below is denser than normal 70gsm at 102 microns, the same as an 80gsm sheet.
