Frequently asked questions.
Is A0 the biggest sized paper?
No, A0 isn’t actually the biggest paper size available. 4A0 and 2A0 are both bigger than A0, as are B0 and C0. Although 4A0 and 2A0 aren’t defined by ISO 216, they are often used when very large paper sizes are needed. Both these formats derive from the German DIN 476 standard.
Is A0 paper bigger than A1?
Yes, A0 is bigger than A1. To be precise, A0 is 841 mm x 1189 mm and A1 is 594 x 841 mm. Within the A paper series, it’s important to remember that the lower the number, the bigger the paper size. So, A0 is the biggest paper size in the series, followed by A1, then A2 etc.
