A5 paper size Guide.

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. 

The dimensions of a5 paper.

The A5 paper size in cm is 14.8 x 21 cm and 148 x 210 mm in millimetres. It has a printing area of 312.5 cm² or 0.031 m². The A5 paper size in inches is 5.82 x 8.26, with a printing area of 48.43 sq inches.

As we have seen, the standardisation of formats keeps proportions consistent: 

• A5 = ¼ of A3

• A5 = ½ of A4

• A5 = 2 x A6

• A5 = 4 x A7

When it comes to A5 pixel sizes, it depends on the image resolution used for your file: 

• The printing of an A5 format in 300 dpi (dots per inch) is based on 1754 x 2480 pixels/inches

• The printing of an A5 format in 200 dpi is based on 1169 x 1654 pixels/inches

• For a low-resolution in 72 dpi, it will correspond to 421 x 596 pixels/inches

The A5 paper size is one of the smallest printable formats in the A range, making it widely sought after by both professionals and individuals alike.
