Poster Sizes Explained: A0, A1, A2, A3, A4 and How to Choose
Quick answer: Standard poster sizes are A0 (84.1 × 118.9 cm), A1 (59.4 × 84.1 cm), A2 (42 × 59.4 cm), A3 (29.7 × 42 cm) and A4 (21 × 29.7 cm). The most popular for Lagos shopfronts and events is A1. This guide gives each size in centimetres, inches and millimetres, then helps you pick the right one, the right paper and the right way to display it.
Poster sizes at a glance (A0 to A4)
These are the standard A-series poster sizes. Each step up roughly doubles the area of the one below it, so an A1 is twice the size of an A2.
| Size | cm | inches | mm | Best poster use in Lagos |
|---|---|---|---|---|
| A0 | 84.1 × 118.9 | 33.1 × 46.8 | 841 × 1189 | Largest poster seen from across a room or street |
| A1 | 59.4 × 84.1 | 23.4 × 33.1 | 594 × 841 | Shopfront posters and events (most requested large size) |
| A2 | 42.0 × 59.4 | 16.5 × 23.4 | 420 × 594 | Notice boards indoor promos and wall art |
| A3 | 29.7 × 42.0 | 11.7 × 16.5 | 297 × 420 | Close-up reading like menus and in-store signs |
| A4 | 21.0 × 29.7 | 8.3 × 11.7 | 210 × 297 | Smallest standard poster (office-paper size) |
Which poster size should you choose?
Pick by viewing distance. A0 and A1 read from far away and dominate a wall, so they suit shopfronts, stage areas and outdoor-facing windows. A2 is the all-rounder for indoor walls and notice boards. A3 and A4 are for close-up reading where someone is standing right in front of it. If you are not sure, tell us where it will hang and we will recommend a size.
Paper and finish options
The paper changes how a poster looks and how long it lasts. The common choices:
- Gloss: bright, punchy colours with a shine. Best for photos and bold graphics.
- Matte: no glare, easy to read under lights. Best for text-heavy posters.
- Satin or silk: a middle ground, rich colour without the full shine.
- Weight (gsm): heavier paper from 170 to 250gsm feels premium and resists curling; lighter stock suits short-term posters or large quantities.
Mounting and display
A great poster needs a clean way to hang:
- Snap frames: aluminium frames that snap open to swap posters in seconds. Reusable and tidy.
- Foam board mounting: the poster is bonded to a rigid board so it stands or leans without curling.
- Lamination: a protective layer for posters that will be handled or live outdoors.
