INTRODUCTION
Here’s the twist most business owners don’t realise:
Choosing the wrong poster size can cost you engagement, visibility, and even sales.
You might be wondering: “Should I print A3 or A2 posters?”
If you wait too long deciding, your competitor might already be catching eyes with larger, more readable posters.
Let’s explore the differences and show you how to pick the perfect size for maximum impact.
What Are A3 and A2 Posters?
A3 and A2 are standard UK poster sizes based on the international A-series (ISO 216).
- A3 (297 × 420 mm / 11.7 × 16.5 in):
- Ideal for noticeboards, offices, and indoor events
- Compact, cost-effective, easy to distribute
- A2 (420 × 594 mm / 16.5 × 23.4 in):
- Perfect for medium-to-large spaces, shops, exhibitions, and events
- Larger size means more visibility from a distance
Here’s the twist: A2 posters draw attention faster, but A3 works best for close-up viewing and budget-friendly campaigns.
Key Questions People Ask
1. Which is more common in the UK – A3 or A2?
- A2 is slightly more popular for advertising and events, while A3 is used for office or indoor displays.
2. Can I use an A3 poster outdoors?
- You can, but the smaller size may reduce readability at a distance.
3. How far away can people read A3 vs A2 posters?
- A3: Best viewed from 1–2 meters
- A2: Readable from 3–5 meters, ideal for shops or exhibitions
4. Are A2 posters more expensive than A3?
- Yes, slightly. The bigger size uses more material and ink, but the increased visibility often outweighs the cost.
5. Can I frame both sizes easily?
- Both A3 and A2 have widely available frames in the UK.
Benefits of Choosing the Right Poster Size
| Benefit → Pain Point | Explanation |
|---|---|
| Increased Visibility → People miss small posters | A2 posters grab attention in larger spaces or crowded areas. |
| Cost-Effectiveness → Overspending on unnecessary large posters | A3 works perfectly for small indoor campaigns. |
| Professional Appearance → Poor layout or small text | Proper sizing ensures text is readable and graphics are clear. |
| Flexibility → Wrong size limits placement | A3 fits noticeboards; A2 can be mounted in windows or walls. |
| Better ROI → Posters ignored due to size | Right size improves engagement, click-throughs, and conversions. |
Mistakes to Avoid
❌ Using A3 in high-traffic outdoor areas → text becomes unreadable
❌ Overcrowding A2 with too much information → dilutes message
❌ Ignoring viewing distance → size must match how far audience is
❌ Not considering frame or mounting options → poor presentation
The #1 mistake: thinking smaller is always cheaper. Visibility is the real ROI driver.
How to Choose Between A3 and A2 Posters
- Step 1: Assess your display space – small noticeboard → A3, window or shop wall → A2
- Step 2: Consider your audience distance – further away? Choose bigger
- Step 3: Evaluate content – long messages need larger posters
- Step 4: Budget vs impact – sometimes slightly larger size is worth the investment
Pro Tip: Many marketers combine A3 and A2 posters use A3 for handouts or indoor boards, A2 for walls and public areas.
