Art Print Sizes Explained: A4 to 24×36 and What Fits Where

Art print sizes fall into two families: the international A series used across Europe, the UK and Australia (A5 to A1), and the inch-based sizes common in North America (5×7 up to 24×36). The right size depends less on the print than on the wall and furniture around it: as a rule, art above a piece of furniture should be about two-thirds of its width. Get that proportion right and almost any print will look as if it belongs.

Below is a plain-language size chart, the rule we use for matching prints to walls, and the mistakes we see most often when people hang art at home.

The art print size chart

These are the standard sizes you will meet when buying prints and frames. Measurements are for the print itself, before any mount or frame.

A series (ISO) sizes

• A5, 14.8 × 21 cm (about 6 × 8 in). Postcard-plus. Best on a desk, a shelf or propped on a narrow ledge.
• A4, 21 × 29.7 cm (about 8 × 12 in). The size of a sheet of printer paper. Good for small walls, bathrooms, beside a light switch or in a cluster.
• A3, 29.7 × 42 cm (about 12 × 16.5 in). The most versatile size. Works above a small console, a bedside table or in pairs.
• A2, 42 × 59.4 cm (about 16.5 × 23.4 in). A real presence on a wall. Suits hallways, above a desk or as one of a pair above a bed.
• A1, 59.4 × 84.1 cm (about 23.4 × 33 in). A statement piece for above a sofa, sideboard or bed.

Inch-based sizes

• 5×7 in (12.7 × 17.8 cm) and 8×10 in (20.3 × 25.4 cm). Small, intimate sizes for desks, shelves and tight gallery groupings.
• 11×14 in (27.9 × 35.6 cm) and 12×16 in (30.5 × 40.6 cm). Mid-sized and easy to place; roughly comparable to A3.
• 16×20 in (40.6 × 50.8 cm) and 18×24 in (45.7 × 61 cm). Medium-large. Comparable to A2 and a good default for a single piece on a modest wall.
• 24×36 in (61 × 91.4 cm). Poster scale. The usual choice for one large print above a sofa or bed.

In Europe you will also find frames sold in 30 × 40 cm and 50 × 70 cm. These are handy middle grounds, and A-series prints sit inside them comfortably with a mount.

Aspect ratio: why some prints will not fit some frames

Two prints can have similar areas but different shapes, and the shape, or aspect ratio, decides which frames they fit.

• A series share one ratio, roughly 1:1.41, so an A4 design scales perfectly to A3, A2 and A1.
• 2:3 covers 4×6, 12×18 and 24×36 in. Taller and slimmer than A sizes.
• 3:4 covers 12×16 and 18×24 in, and 30 × 40 cm. Slightly squarer.
• 4:5 covers 8×10 and 16×20 in. The squarest of the common formats.

When a print and frame have different ratios, a mount solves the problem: the opening is cut to the print, and the outer edge fits the frame. Our guide on how to frame art prints explains mount widths, and framing art prints the Japandi way covers frame colour and material.

The wall-width rule: matching size to space

Choosing art print sizes by eye is hard, because walls always look smaller on a phone screen than in real life. A simple rule removes the guesswork.

Above furniture: two-thirds

Measure the width of the sofa, bed, sideboard or desk beneath the art. The framed piece, or the full width of a group, should be roughly two-thirds of that, and somewhere between half and three-quarters still looks right. A 210 cm sofa suits art around 120 to 150 cm wide in total; that might be one 24×36 in print in a frame, or a pair of A2 prints with a gap between.

On a bare wall: think in sections

Where there is no furniture, treat the space between doors, windows or corners as one section. The art should fill around half to two-thirds of that section's width. A narrow strip of wall between two doors might take a single A3; a long, empty hallway might take a row of three.

Height: the centre at eye level

Hang so the centre of the artwork sits around 145 to 150 cm from the floor. Above furniture, leave 15 to 25 cm between the top of the furniture and the bottom of the frame. For balancing art with the rest of a room's proportions, our guide to the 30-30-30 rule is a useful companion.

What fits where: room by room

• Above a sofa. One A1 or 24×36 in print, or two A2 prints side by side. Small prints here almost always look lost.
• Above a bed. A single landscape-format A1, or a pair of A2 prints spaced evenly over a double or king. Our guide to art above the bed covers height and safety.
• Above a desk. A2 or 18×24 in, hung slightly lower than usual so it sits in your eyeline when seated.
• Hallways and landings. A3 or A2, often in a row of two or three with equal spacing.
• Bathrooms and kitchens. A4 or A3, behind glass and away from steam and splashes.
• Shelves and ledges. A5, A4 or 8×10 in, propped and lightly overlapped with an object or two.

Common mistakes with print sizes

1. Going too small. The most common error by far. A single A4 above a three-seater sofa reads as an afterthought. When in doubt, size up.
2. Forgetting the frame and mount. A 50 × 70 cm frame with a generous mount can hold an A3 print and look far larger. Plan with the framed size, not the print size.
3. Mixing too many ratios in a group. A gallery wall with five different shapes looks restless. Choose one or two ratios and repeat them; see the Japandi gallery wall for layouts.
4. Hanging too high. Art floating near the ceiling disconnects from the room. Keep the centre near eye level and close to the furniture beneath.
5. Crowding the wall. Leave space around the art. Open wall is part of the composition, a principle we explore in the art of negative space.

Choosing with confidence

Art print sizes feel complicated until you reduce them to two questions: how wide is the furniture or wall section, and what shape is the frame? Aim for two-thirds of the width, match the ratio or use a mount, and hang the centre at eye level.

Before you order, cut a sheet of paper or card to the framed size and tape it to the wall for a day. It is the simplest way to see whether a print will hold its own, and it saves a great deal of second-guessing.

Frequently asked questions

What size print should go above a sofa?

Aim for art that is about two-thirds the width of the sofa. For a typical three-seater, that means a single large print such as A1 or 24×36 in, or a pair of A2 prints with a small gap. Hang the bottom of the frame 15 to 25 cm above the sofa back.

Is A3 bigger than 11×14?

Slightly, yes. A3 measures 29.7 × 42 cm, while 11×14 in is 27.9 × 35.6 cm, so A3 is a little wider and noticeably taller. The two have different proportions, so an A3 print needs a mount or a custom frame to fit an 11×14 opening.

What is the most popular art print size?

There is no single standard, but mid-sized prints such as A3, A2, 12×16 in and 18×24 in are the most versatile because they suit most walls and pair easily. Large statement sizes like A1 and 24×36 in are popular for above sofas and beds.
