Aspect ratios explained simply – how to find the perfect image format for your wall

🖼️ Aspect ratios explained simply – how to find the perfect image format for your wall

When choosing wall art, you often come across terms like 2:3 ratio , 3:4 ratio , or 4:5 ratio . But what do these actually mean?
In this article, we'll show you how to find the right aspect ratio for your wall art – and which format best suits your home.

📏 What does a ratio size mean?

The aspect ratio describes the relationship between the width and height of an image.
For example:

• 2:3 ratio → classic photo format (e.g. 20×30 cm, 40×60 cm)
• 3:4 ratio → slightly square, ideal for gallery walls (e.g. 30×40 cm)
• 4:5 ratio → harmoniously balanced, often used for art prints (e.g. 24×30 cm)
• ISO Ratio (A-formats) → as you know them from paper sizes (A4, A3, A2, …)

The aspect ratio remains the same – no matter how large you choose the image. A 20×30 cm image in a 2:3 ratio therefore looks exactly the same proportioned as a 60×90 cm image.

🖼️ Which format suits your space?

• 2:3 ratio
  Perfect for single images, large wall surfaces or panoramic shots.
  → Goes well over sofas, beds or sideboards.
• 3:4 ratio
  Slightly more compact – ideal for gallery walls or smaller rooms.
  → Appears balanced and classic.
• 4:5 ratio
  Popular for art prints and portraits.
  → Works great in combination with square formats.
• ISO Ratio (A-series)
  Useful if you are looking for standardized sizes (A4, A3, A2…).
  → Easy to frame, as suitable frames are readily available.

🌿 Tip: Choose the ratio and size to suit the wall.

Think about how much space you have on your wall beforehand:
👉 Would you like one large statement image or would you prefer to combine several smaller formats?
It's best to combine images with the same ratios to make your gallery wall look harmonious.
