What size poster should you choose for your wall? A practical guide
A well-chosen poster transforms an ordinary wall into a true artistic composition. But between A4 and 70×100 cm, how do you find your way? This guide gives you all the keys to choosing the ideal poster size according to your room, your furniture, and your style.
The Golden Rule: Proportion and Visual Balance
Before choosing a format, remember two fundamental principles:
- A poster should occupy 60 to 75% of the width of the furniture below it (sofa, bed, console).
- The ideal hanging height is 145 to 150 cm from the floor to the center of the artwork — approximately eye level.
These two rules are enough to avoid the most common mistakes and ensure a harmonious result, no matter the room.
Poster above a Sofa
The living room is where a poster has the most impact. Placed above the sofa, it structures the space and asserts your decorative identity.
Recommended Sizes for the Living Room
- 50×70 cm — ideal for a 2-seater sofa
- 60×90 cm — versatile, very popular
- 70×100 cm — large format for a 3-seater sofa or more
These formats create an elegant focal point, whether it's a vintage jazz poster, a Bauhaus composition, or an editorial floral motif.

Posters above the Bed
In a bedroom, the wall above the bed is the most visible surface. Two approaches work depending on the desired effect.
A Large Central Poster
An A1 (59.4×84.1 cm) or 70×100 cm format placed in the center creates a minimalist and soothing decoration. This is the ideal approach to showcase a strong piece — a Matisse print, a botanical watercolor, or a jazz club poster.
Two or Three Aligned Posters
Three A3 (29.7×42 cm) or 40×60 cm posters arranged side by side form a modern and balanced triptych. This composition is particularly effective with artworks from the same graphic family or with the same color palette.

Poster for a Small Wall or Hallway
Small spaces deserve as much attention as large rooms. A well-decorated hallway immediately sets the tone of your interior.
Recommended Sizes for Small Spaces
- A4 (21×29.7 cm) — perfect solo or in a series
- A3 (29.7×42 cm) — ideal for a compact wall gallery
- 40×60 cm — slightly more imposing, perfect for an entryway
Combine several posters of the same style for a coherent and curated look, without overcrowding the space.
Creating a Gallery Wall
The gallery wall is one of the most enduring decor trends. It allows you to combine several formats and styles for a lively and personal wall.
How to Create a Successful Gallery Wall
- Choose an anchor format: a large poster (60×90 cm or 70×100 cm) as the centerpiece.
- Surround it with smaller formats: A3 or 40×60 cm as satellites.
- Maintain graphic consistency: same palette, same era, or same style (Bauhaus, vintage, botanical…).
- Space uniformly: 5 to 8 cm between each frame for an airy and neat look.
