Did you know?

For standard paper sizes to work out the next paper size, you simply need to double the length of the short-edge of the sheet. i.e. A4 to A3, take the size of A4 (210mm x 297mm) and double 210mm to make 420mm, meaning A3 = 297mm x 420mm. To go down, you simply do the same in reverse, but halving the longest edge.
