Paper formats

Basic Series A

The most well-known series of formats is the basic A series. We commonly encounter formats A3, A4, or A5 in magazines, notebooks, drawings, etc. The basic format of the A series is A0. Its area, rounded to the nearest decimal place, equals 1m². From format A0, other formats are created in a descending sequence by halving the longer side (A1, A2, A3, A4, ...). See the image.
