How is made? Paper is made by chipping up timber, soaking it in water to break it down into fibres and then compressing the fibres together, bleaching them and drying them out and cutting the material up into the universal size needed.

What sizes does paper come in? Paper comes in standard sizes that are known across the world (A0, A1, A2, A3, A4 etc. This allows paper to be made anywhere in the world and allows communication across the world. The paper sizes basically half every time you go down a size.

Paper is also measured in GSM (Grams per metre squared) this usually determines paper quality, higher weights mean higher quality.
