The A5 paper size belongs to the ‘A’ series of paper formats which, from A0 right through to A10, retain their proportions between width and length. For example, the width of the A5 format is equal to the length of the A6 format. Similarly, the length of the A5 format is equal to the width of the A4 format. 


This correlation between paper sizes was first described in 1786 by the German scientist Lichtenberg, then normalised in 1922 by Porstmann and the German DIN 476, to evolve towards the ISO 216 standard in 1975.
