A Paper Sizes Explained

A Sizes for Posters or Paper

The simplest way to explain the aspect ratio of A sizes is that two of one size will equate to one of the next size up. For example, 2 x A4 sheets side by side (portrait) will equate to 1 x A3 page and 2 x A3 pages side by side (portrait) will equate to 1 x A2 size.

The larger the size of paper the smaller the number - A10 is the smallest and A0 size is the largest.

ISO 216 specifies the international standard of paper sizes which is used in most countries worldwide apart from Mexico, Dominican Republic, USA and Canada.

When purchasing notice boards, if the sizes are quoted in 'A' sizes then this is the visible area for the poster and the frame width will need to be added to all four sides to give the overall size.
