Understanding Poster Sizes (What You’re Actually Buying)
When buying posters online, one of the most common points of confusion is size. Unlike custom print services, most posters are printed in fixed sizes determined by the publisher or artwork licensing agreement. This means the size is part of the product itself — not something you choose at checkout.
At Poster Plus, each poster listing clearly shows the exact size you will receive, whether that’s Maxi, A1, Mini or other standard formats. Below is a simple guide to help you understand what those sizes actually look like in real life.
Common poster sizes explained
- Maxi (61 × 91.5 cm) – One of the most popular large poster formats. Ideal for feature walls and bold artwork.
- A1 (59.4 × 84.1 cm) – Slightly smaller than Maxi but still large and impactful.
- Mini (40 × 50 cm) – A mid-size option suitable for smaller walls or grouped displays.
- Slim (30.5 × 91.5 cm) – Compact size, half the size of a maxi.
Note: Exact sizes may vary slightly depending on the publisher and print source.
What these sizes actually look like on a wall
It can be difficult to visualise poster sizes from numbers alone. A simple way to think about it is how much wall space they occupy in a typical room:
- Maxi / A1: Strong feature pieces — ideal above beds, sofas or desks
- Mini: Balanced mid-size — great for gallery walls or secondary focal points
- Giant: Bold pieces — for that large empty space
Why poster sizes aren’t always interchangeable
Unlike custom prints, most posters are produced in fixed formats. This means the artwork, layout, and licensing are all designed around a specific size. Because of this, posters cannot usually be resized at checkout.
This ensures you receive the artwork exactly as intended by the publisher or artist, without distortion or cropping.
Choosing the right space for your poster
A simple rule of thumb is:
- Large posters (Maxi / A1) – best for open wall space or focal points – the most popular choice and the biggest range
- Mini posters (40x50cm) – best for small wall areas or grouped displays – think about that column or nook or spot next to taller furniture
- Giant posters (100x140cm) – best for that large empty spot that doesn’t compete with a television or window. Make a feature wall!
Final note
The best way to choose a poster is by thinking about where it will live in your space. Each size is designed to suit different types of walls, rooms, and styling preferences. But if you really love an image you’ll find a space for it!
