A2 Paper Size: Dimensions, Poster Uses, and Printing Tips
A2 paper measures 16.54 × 23.39 in (420 × 594 mm). Learn when it is useful for posters, displays, and large diagrams.
A2 paper measures 16.54 × 23.39 inches (420 × 594 mm). It is twice the area of A3 and four times the area of A4, which makes it a practical poster size for displays, workshop boards, and diagrams that need to be read from farther away.
Key dimensions
| Item | Value |
|---|---|
| Width | 420 mm / 16.54 in |
| Height | 594 mm / 23.39 in |
| Area | 2× A3 / 4× A4 |
| Typical role | Poster or display sheet |
When it makes sense
A2 is appropriate when the page must work at wall distance or table distance for several people at once. Think signage, classroom displays, event schedules, product boards, and large workflow charts that would feel too busy on A3.
What to watch next
The tradeoff is portability. A2 is much easier to read than A3, but it is already beyond what most home or office printers can handle directly. For many teams, the decision is really “print shop poster size” versus “office-friendly large sheet.”
Printing tips
If you need A2 output, confirm the device path before you design around it. Many teams draft on A4 or A3 and then send the final file to a shop. Keep vector PDFs, avoid raster upscaling, and test readability at distance.
