ISO standard determines the paper dimensions for the A paper series. The most common paper sizes are A0, A1, A2, A3, A4, A5. The table below shows the dimension of the most common A series paper sizes.
|Paper size||Dimensions (cm)||Paper Area|
|Α5||14.8 x 21 cm||0.03108 m2|
|Α4||21 x 29.7 cm||0.0612 m2|
|Α3||29.7 x 42 cm||0.125 m2|
|Α2||42 x 59.4 cm||0.25 m2|
|Α1||59.4 x 84.1 cm||0.50 m2|
|Α0||84.1 x 118.9 cm||1 m2|
Notice that if we split an A1 paper into two equal parts we get two A2 papers. If we split an A2 paper into two equal part we get two A3 papers. If we split an A3 paper into two equal part we get two A4 papers and so on. This is shown visual in the picture below.
