A bit of further information on A paper sizes
The standard international paper size is also known as ISO format. It is controlled and agreed by the International Organization for Standardization. Standard sizes are applied to most printed items including posters, leaflets, and household printer paper, unless a special size is specified. In the US the equivalent of ISO A4 is known as US Letter – 215.9 x 279.4 mm / 8.5 x 11 inches.
Whats the point in ‘standard’ paper sizes?
- Created conformity
- Easy to understand
- Universal amongst different countries
- Cheaper for printers to produce using a ‘standard’ cutter size
Width by height, or the other way round?
Some customers ask for the ‘length and width’ of paper but I prefer to stick to referring to it as width and height. There’s a creative saying that goes “along the corridor and up the stairs” so you always start with width followed by height. That’s the process that has been a helpful way of reminding myself which to provide first and last when communicating with suppliers. Maybe don’t mention the bit about the stairs though, they might laugh at you lol.
