Paper Sizes Guide


The ISO paper sizes are widely used in the printing industry. Below we've compiled a size chart graphic to visually show the difference between the A-sizes. Whilst many large format printers work in rolls as well as ISO paper sizes, they are still widely used when discussing posters, small signage, pavement signs and billboards.
