Poster Sizes: Every Format We Print, and What Each One Looks Like on a Wall

Choosing a poster size is usually a question of two things: what the wall can carry, and what sits below it. A 30×40 print above a sofa looks lost; a 70×100 above a bedside table looks like a billboard. This page lists every format we print, in centimetres and inches, with the proportions worked out against ordinary furniture.

The seven sizes we print

Format	Centimetres	Inches (approx.)	What it usually suits
30×40	30 × 40 cm	11.8 × 15.7 in	Small wall, shelf top, grouped with others
A3	29.7 × 42 cm	11.7 × 16.5 in	Almost identical to 30×40, slightly taller
40×50	40 × 50 cm	15.7 × 19.7 in	Hallway, narrow wall, above a desk
A2	42 × 59.4 cm	16.5 × 23.4 in	Bedroom, paired prints, small living room wall
50×70	50 × 70 cm	19.7 × 27.6 in	The default above a sofa or a sideboard
61×91	61 × 91 cm	24 × 35.8 in	Large wall, single statement piece
70×100	70 × 100 cm	27.6 × 39.4 in	Long wall, tall ceiling, above a low bench

A3 and A2 belong to the ISO A series, where each size is half the area of the one before it. That is why A3 is very close to 30×40 and A2 sits between 40×50 and 50×70: the A series keeps a fixed proportion of 1:1.414, while the 30×40, 40×50, 50×70 family keeps a fixed step in width. If you are replacing a print you already own, measure it rather than guessing from the name.

What each size looks like against furniture

Proportion matters more than the number on the label. As a rule of thumb, a poster should sit between one half and two thirds of the width of the furniture below it.

Furniture	Typical width	Poster width that works	Format
Bedside table	45 cm	25–30 cm	30×40 or A3
Desk	120 cm	50–70 cm	40×50 or A2
Sideboard	150 cm	60–90 cm	50×70 or 61×91
Sofa (two seat)	160 cm	70–100 cm	50×70 or 70×100
Sofa (three seat)	210 cm	100–130 cm	70×100, or two 50×70 side by side
Double bed (headboard)	160 cm	70–100 cm	50×70 above each side, or one 70×100 centred

Two smaller prints often fill a wall better than one large one, and they are easier to move when the room changes. A common pairing is two 50×70 frames with 10–15 cm between them, centred over the furniture rather than over the room.

How high to hang it

The number that saves the most arguments is the centre height of the print: 145–150 cm from the floor, which is roughly eye level for most adults. Above furniture, keep 20–30 cm of empty wall between the top of the furniture and the bottom of the frame, and never less than 15 cm or the print looks like it is resting on the table.

In a stairwell or a hallway, follow the line of the stairs and keep the gap between frames constant. In a room with a very high ceiling, raise the centre to around 160 cm so the print does not look stranded above the furniture.

Frames and mounts change the footprint

A thin frame adds around 3 cm on each side: a 50×70 print becomes roughly 56×76 cm on the wall. A mount (passe-partout) adds more, typically 5–10 cm per side, so a mounted 50×70 can reach 70×90 cm. If you are measuring a gap between a door and a corner, measure the framed size, not the paper size.

We send prints unframed, so the frame is your choice. A narrow black or natural wood profile keeps the edges of the image clean and works with both sparse and busy rooms.

Choosing by room

Hallway: 40×50, hung at eye level in a row, or one 50×70 at the end of the corridor.

Living room: 50×70 above a sideboard or sofa; 70×100 if the wall is long and mostly empty.

Bedroom: A2 or 50×70, centred above the headboard; two 30×40 if you prefer a calmer wall.

Kitchen: 30×40 or A3 near a dining table, where the print is read from close range.

Office: 40×50 at eye level in front of the desk.

Which one to order

If you are unsure, take the size of the furniture you are hanging above, halve it, and look for the closest format. A 150 cm sideboard points to 50×70; a 210 cm sofa points to 70×100. When two sizes are equally plausible, the smaller one is usually the safer choice: an undersized print on a large wall looks sparse, but an oversized one looks like a mistake.
