One of the details we may be interested in having is the area of paper we have in a reel, that is, the square meters we are buying in that “roll”. As an example, if we have a reel 140 cm wide by 1,000 cm long and we want to know how many square meters there are, we must multiply both lengths.

Therefore, in this coil we would have 140 square meters of paper. When we cut this roll into standard sheet sizes, we are left with 70 x 100 cm sheets. To know its area, we must calculate it in the same way:

For example, we can have two types of paper, both 130 g/m², but one with a thickness of 234 µm and the other with 143. The volume would be calculated by dividing both values and obtaining as a result that one will have a volume of 1.8 (light and thick) and the other of 1.1 (compact and thin). At approximately 1.3 cm³/g we can begin to consider that a paper is volume.

The specific volume, or “bulk” in English, is a very important factor in publishing production and influences the perception of the final result of a work. If we want to give the impression of a thick book, rich in content, a high volume paper should be used. If the idea is to have a lot of text but still maintain a thin book spine, a low-volume paper will be more appropriate.  I have seen very expert printers – and from whom I have learned so many things – guess the grammage simply by touch, by rubbing it with their fingers, but this method was only useful for the most normal and usual types of paper. They never took any risk with volume and special papers, for a reason.
