Have you ever wondered how thick an average sheet of paper is? Well, a single sheet of paper used most often in photocopiers or printers has a thickness of about 0.05 – 0.1 mm. Of course, the exact thickness depends on the grammage of the paper. The value given is an average, assuming a sheet weight of approximately 100 g / m2.
As a curiosity: If we fold a sheet of A4 paper in half, assuming that the unfolded sheet has a thickness of 0.099 mm, and ignoring the fact that we cannot fold it more than 6-8 times, it will be 0.198 mm after the second fold. After the second folding 0.396 mm. After the 23rd fold, it will be a thickness comparable to a kilometer. After 30 folds, we will reach a thickness of 100 km.
