What size is A1 paper?
A1 is 594 × 841 mm (59.4 × 84.1 cm, or 23.4 × 33.1 inches). It's half the size of A0 and twice the size of A2, which makes it a popular size for posters and display boards.
How many A4 sheets fit on A1?
Eight. Every A size is exactly half of the one above it, so A1 holds 2 × A2, 4 × A3 or 8 × A4 sheets.
What's the difference between A4 and A5?
A4 is 210 × 297 mm and A5 is 148 × 210 mm — A5 is exactly half of A4, the size you get by folding an A4 sheet in half. A4 suits letters and flyers; A5 is popular for leaflets and booklets.
What resolution should my artwork be?
Images should be 300 DPI at the size they'll be printed. The pixel sizes in the table show what that means for each A size, for example 2,480 × 3,508 pixels for A4.
Do I need to add bleed?
Yes, if your design runs to the edge. Add 3 mm of bleed on every side (so an A4 file becomes 216 × 303 mm) and keep text at least 3 mm inside the trim line.
Why are A sizes this shape?
They all share a width-to-height ratio of 1 : √2 (about 1 : 1.414). Cutting a sheet in half keeps the same proportions, so a design scales between sizes without stretching.
