Paper Sizes Guide

ISO paper standards are widely used throughout printing. Originally for the litho and screen print industries where sizes need to be fixed, they are now used extensively in the large format digital printing market. One difference is many large format digital printers use rolls rather than sheets of paper. But graphics in products such as poster frames, billboards, pavement signs and poster frames come in popular set sizes, usually from the A or B series. European displays are metric where in the UK we still have imperial sizes such as 20" x 30".
