Difference Between A1, A2, A3, and A4 Sizes
The A-series sizes are based on the ISO 216 standard. Each size is half the area of the previous size (A0 → A1 → A2 → A3 → A4). This is very useful for sublimation aluminium sheets because it determines the surface area available for printing images or graphics.
Key Points:
- A1: Large format, suitable for posters, wall art, or large signage.
- A2: Medium-large, often used for small posters, certificates, or decorative panels.
- A3: Standard medium size, popular for printing photos, DIY projects, and promotional panels.
- A4: Small size, ideal for personal prints, small awards, or home décor projects.
A-Series Sheet Sizes Table
| Size | Dimensions (mm) | Dimensions (inch) | Common Use |
|---|---|---|---|
| A1 | 594 × 841 | 23.4 × 33.1 | Large posters, wall art, signs |
| A2 | 420 × 594 | 16.5 × 23.4 | Medium posters, certificates, displays |
| A3 | 297 × 420 | 11.7 × 16.5 | Photo panels, DIY crafts, promotions |
| A4 | 210 × 297 | 8.3 × 11.7 | Small prints, awards, home décor, photo gifts |
