| Size | Dimensions | Good for | Your design at least |
| A4 | 21 × 29.7 cm | notice board, door, small announcement | 2480 × 3508 px |
| A3 | 29.7 × 42 cm | window, counter, announcement | 3508 × 4961 px |
| A2 | 42 × 59.4 cm | corridor, shop, at eye level | 2480 × 3508 px |
| A1 | 59.4 × 84.1 cm | shop window, event, legible from a distance | 3508 × 4967 px |
| A0 | 84.1 × 118.9 cm | hall, trade show, large and visible from afar | 4967 × 7022 px |
The pixel counts assume 300 DPI for A4 and A3 (which you view up close) and 150 DPI
for A2 and larger (which you view from a distance). Have a fixed frame, alcove or window?
Then print the poster to size, made to fit exactly.
Printing an A1 poster
A1 (59.4 × 84.1 cm) is the most popular large poster size: big enough for a
shop window or event, and still easy to hang. Make sure the text in your design is large
enough to read from a few metres away.
Printing an A0 poster
A0 (84.1 × 118.9 cm) is the largest standard size, for a hall, trade show or long
corridor. Work with a high-resolution design or in vector, and it will stay sharp
at that size too.
