|Size #||72 dpi/ppi

* PPI (pixels per inch) = DPI (dots per inch) = Resolution
As one of the ISO standard paper sizes, A6 sizes fully comply with the principle of paper length ratio of √2:1. Under this rule, each piece of paper cut or folded at the center line of the long side produces a piece of paper of exactly the same size as its aspect ratio, and is named the next on the size number. For example, A6 size is cut from the A5 size, then the A6 size can be cut to produce the A7 size. The entire ISO A series paper size is produced based on this. The A0 is the largest size in the series and is exactly equal to 1 square meter.Then there are A1, A2, A3, A4, A5, A6, A7, and the minimum sizes to A8, A9, A10, etc..
With a small size, paper of A6 size is easy to carry, which makes it perfect to be used as a carrier of propaganda content after printing eye-catching and large font contents and patterns. Therefore, higher paper weight A6 card can also be used to make brochures for distribution in crowded places, because it does not take up space and does not appear messy in places, easy to read, and can really attract people’s attention.
