Online Printing Explained: Paper sizes

22nd November 2011

Paper Size and Printing with

The A Class is an international standard. This means that no matter where you are in the world, an A5 wedding order of service booklet, for example, will always be will always be an A5 booklet. In essence, any piece of paper is considered to be in the A Class if it has the correct ratios (height vs lenth). This ratio has the unique quality that if it is folded in half lengthways, it will have exactly the same aspect ratio. A0 (which is designed to have the area of 1 square metre), for example, becomes a piece of A1 when folded in half lengthways. This then becomes a piece of A2 and so on. This characteristic holds true for the other two main paper size families: B and C.
