Everydayprint’s most popular printed poster size is A2, but we have many people questioning the actual size in millimetres.

So below is a table which defines all the A series of paper sizes fro A7 to 2A0

A7 - 105mm x 74mm
A6 - 148mm x 105mm
A5 - 210mm x 148mm
A4 - 297mm x 210mm
A3 - 420mm x 297mm
A2 - 594mm x 420mm
A1 - 841mm x 594mm
A0 - 1189mm x 841mm
2A0 - 1682mm x 1189mm

The above sizes are the standard finished paper sizes. If you are designing artwork for print you must add 5mm bleed to each side of the page (i.e. add 10mm to the width and 10mm to the height of the page)
