How to Hang a Poster: The Complete Guide

A beautiful poster hung in the wrong place loses half its impact. Too high, too low, off-center: these small errors are noticeable, even subconsciously. Here's how to hang a poster correctly, whether it's a single piece or an entire gallery wall. This guide covers everything: ideal height, fasteners, gallery wall arrangements, and specific considerations for each room.

1. The Right Height to Hang a Poster

The reference rule for galleries and museums: the center of the poster should be approximately 145–150 cm (57–59 inches) from the floor, which is average eye level. This is the most reliable guideline, regardless of room size or ceiling height.

Above furniture (sofa, console, headboard), forget the floor as a reference: align with the furniture instead. Leave 15 to 30 cm (6 to 12 inches) between the top of the furniture and the bottom of the frame — enough to visually connect the two elements without them touching.

• Above a sofa — 20 to 25 cm (8 to 10 inches) between the top of the backrest and the bottom of the poster.
• Above a headboard — 15 to 20 cm (6 to 8 inches) between the top of the headboard and the bottom of the poster.
• Above a console table — 15 to 20 cm (6 to 8 inches) between the top of the console and the bottom of the frame.
• Alone on a wall — center at 145–150 cm (57–59 inches) from the floor, horizontally centered.
• In a hallway — same rule, vertical format recommended.

2. Preparing to Hang

• Measure and mark — use a tape measure, mark with a pencil.
• Check for horizontality — use a spirit level or a smartphone app.
• Test the placement — use a paper template with masking tape before permanently fixing.
• Check the light — avoid reflections facing a window.

3. With or Without a Frame

A poster flush against the wall creates a light and contemporary look — this is Cassili's preferred approach. The solid oak framed version structures the poster and provides a gallery finish. In a bathroom, a frame is recommended to protect the poster from humidity. Avoid white matting. To learn more: Framed poster or unframed poster: how to choose?

4. Fixing Without Damaging the Wall

• Repositionable adhesive strips (e.g., Command Strips) — up to 500g (1.1 lbs), ideal for rentals.
• Adhesive hooks — up to 2–3 kg (4.4–6.6 lbs).
• Picture rail or track system — for an evolving gallery wall.
• Classic fixation (wall plug + screw) — for heavy frames or large A1 format.

5. Creating a Harmonious Gallery Wall

• Space regularly — 5 to 8 cm (2 to 3 inches) between each poster.
• Arrange on the floor first — photograph before hanging on the wall.
• Same palette, same finish — to avoid a patchwork effect.
• Start from an anchor point — the central or largest poster.
• Limit themes — Architecture + Mineral, or Light + Vegetal.

6. Specific Considerations for Each Room

• Living Room — composition width ≤ sofa width.
• Bedroom — proportionate to bed width.
• Entryway — a single, well-chosen poster above a console table.
• Office — check camera view if visible during video conferences.
• Bathroom — minimum 80 cm (31.5 inches) from splashes, framed option recommended.
• Hallway — a series of aligned posters for a gallery effect.

Mistakes to Avoid

• Hanging too high — the most common mistake.
• A too-small format — go for a larger format or create a composition.
• Irregular spacing — creates a messy impression.
• Mixing frame styles — stick to one type for coherence.

When in doubt: a slightly larger poster, hung a little lower, almost always works better than the opposite.

How to create a harmonious gallery wall?

Arrange on the floor first, space each poster 5 to 8 cm (2 to 3 inches) apart, and start from a central poster. Our configurator helps you visualize the result.

A single A1 format piece, or a composition of 3 posters in 50×70 cm (20x27 inches). A large format visually expands the room rather than overwhelming it.
