The sizes of paper and card commonly used follow the ISO Standard - e.g. A4, A3 etc plus B4, C5 etc. There is also a North America Standard with sizes including letter, legal, ledger, etc.
Note: The ratio of one side of ISO Standard paper to the other is √2 resulting in paper sizes which can be folded in half to create the next size.
The most frequently used paper size is A4. A sheet measures 210 by 297 millimetres (8.27in × 11.7in) and a sheet of ordinary copier paper weighs 5 grams. Other common sizes are:
- A5 = 148mm × 210mm
- A3 = 297mm × 420mm
- A2 = 420mm × 594mm
The base A0 size of paper is defined as having an area of 1m² rounded to the nearest millimetre
