A0 paper size is 841 × 1189 mm (84.1 × 118.9 cm, or about 33.1 × 46.8 inches). It is the largest standard sheet in the ISO A-series and is widely used in Australia for posters, plans, displays, and large-format marketing.
Because A0 has an area of exactly one square metre, it provides substantial space for bold visuals, technical drawings, and messaging that needs to be seen clearly from a distance. Its consistent 1:√2 aspect ratio also allows artwork to scale neatly across other A-series sizes without distortion, making it practical for coordinated campaigns and professional printing services.
Understanding the A-Series Paper Size System
The ISO 216 A-series system is designed so that each size is half the area of the one above it while maintaining the same proportions.
This means:
- 1 × A0 = 2 × A1
- 1 × A1 = 2 × A2
- 1 × A2 = 2 × A3
- 1 × A3 = 2 × A4
In practical terms, one A0 sheet equals sixteen A4 sheets in area.
Standard A-Series Dimensions
| Paper Size | Dimensions (mm) | Common Uses |
| A0 | 841 × 1189 | Posters, plans, large displays |
| A1 | 594 × 841 | Retail posters, presentations |
| A2 | 420 × 594 | Promotional signage |
| A3 | 297 × 420 | Menus, small posters |
| A4 | 210 × 297 | Letters, flyers |
This structured sizing makes it easy to scale artwork up or down without redesigning layouts.

When Should You Choose A0 Over Other Paper Sizes?
Choosing the right paper size depends on visibility, space, and purpose.
Choose A0 when:
- The poster needs to be seen from a distance
- You require detailed technical drawings
- You want maximum impact in large venues
- The design contains maps, diagrams, or scaled layouts
Choose A1 or A2 when:
- Wall space is limited
- The audience stands closer to the poster

A0 works best in open spaces such as shopping centres, trade shows, construction sites, universities, and large offices.
If you’re unsure which size suits your project, consulting an experienced printing provider like DTPS can help you match paper size with purpose and budget.
Paper Stock Options for A0 Printing
Paper selection influences durability, appearance, and overall presentation.
Common A0 Paper Weights
- 150–200 gsm – Suitable for general posters
- 200–250 gsm – More durable and professional finish
- 300 gsm and above – Premium display posters
Finish Options
- Matte finish – Reduces glare, ideal for bright indoor lighting
- Gloss finish – Enhances colour vibrancy
- Satin – Balanced finish between matte and gloss
If the poster will be handled frequently or displayed long-term, lamination or mounting can improve longevity and protect against wear.
Professional printing services such as DTPS can also advise on stock selection depending on whether the poster is for indoor retail, construction site use, or corporate presentation.

Key Setup Tips
- Set document size to 841 × 1189 mm
- Include bleed where required
- Keep important text within safe margins
- Use high-resolution images suitable for large format

If needed, professional pre-press support from experienced providers like DTPS can help ensure files are production-ready.
