8 Gallery Wall Ideas with Posters (Layouts, Sizes & Measurements)
A gallery wall is the fastest way to make a plain room feel personal. The secret is not the posters themselves — it is the layout. Below are eight layouts we see working in thousands of Indian bedrooms, hostels and living rooms, with the count and size you need for each.
1. Above-bed trio
Three A3 posters side by side, 5 cm apart, centred 20–25 cm above the headboard. It needs about 1 m of width. Perfect for one strong theme — three anime characters, three cars or three spiritual artworks.
2. Classic 3 × 3 grid
Nine A4 posters with equal 3–4 cm gaps cover roughly 0.75 × 1 m. Grids look premium because they are perfectly regular, so keep one theme or one colour family. Our anime wall setup pack is made for exactly this layout.
3. Big 4 × 4 collage
Sixteen A5 posters fill about 0.65 × 0.9 m — ideal for a room makeover on a budget. Put the darkest prints in the corners so the wall feels framed.
4. Hero centre
One A3 in the middle with eight A5s around it. The hero poster tells the story (your favourite character, car or deity); the smaller ones support it.
5. Salon / mosaic mix
Two A3, six A4 and six A5 posters in mixed orientation. It looks effortless but needs planning: lay everything on the floor first, take a photo, then copy it to the wall.
6. Staircase diagonal
Five to seven A4 posters climbing with the stairs. Keep the centre of each poster about 145 cm above the step below it.
7. Vertical ladder
Four A4 posters stacked on a narrow wall beside a door or wardrobe — great for quotes you want to see every morning.
8. Desk & shelf combo
Lean two A4s and one A5 on a shelf, overlap them slightly and add a 3D-printed name plate in front.
Three rules that make any layout look professional
- Eye level: centre of the whole arrangement around 145 cm from the floor.
- Equal gaps: cut a cardboard spacer so every gap matches.
- One story: one theme or one colour family per wall.
