Choosing wall art for a child's bedroom should be enjoyable, but selecting the right print size can feel surprisingly difficult. A design may look perfect online, yet it can be hard to imagine whether A5, A4 or A3 prints will suit the space above a bed, beside a cot or over a chest of drawers.
The best size depends on the available wall space, the furniture beneath it and whether you are displaying one print or creating a gallery wall. This practical UK guide explains A5, A4 and A3 print sizes and gives you useful starting points for planning a balanced display.
Quick answer
A5 works well for small walls and compact groups, A4 is a flexible choice for sets of three, and A3 gives a larger wall or statement print more presence. Always check the complete outside frame dimensions before deciding.
Understanding A5, A4 and A3 print sizes
These familiar A-series measurements refer to the print itself. The finished outside dimensions will be larger once you add a frame or mount.
| Print size | Dimensions | Best suited to |
|---|---|---|
| A5 | 14.8 x 21 cm | Shelves, small walls and compact grouped displays |
| A4 | 21 x 29.7 cm | Sets of three, medium walls and spaces above furniture |
| A3 | 29.7 x 42 cm | Larger walls, statement prints and mixed-size galleries |
Before choosing a size, use a tape measure to mark the dimensions on the wall. You can also cut paper templates to the same size and attach them using low-tack tape. This gives you a much clearer idea of how the artwork will look in the room.
Simple width calculation: add the outside width of every frame, then add one gap for each space between the frames. For three frames, that means three frame widths plus two gaps.
Which print size should you choose?
A5 for compact spaces
A5 is useful for narrow walls, shelves, small nurseries and compact grouped displays. One A5 print can look lost on a broad wall, but three coordinated A5 prints can create a clear display without overwhelming a small room.
A4 for flexible bedroom layouts
A4 is often the most flexible starting point for a child's bedroom. It works well in sets of three above furniture, as a personalised centrepiece with two supporting designs, or in a grid of four or six prints. Test an A4 paper template on the wall and remember that the frame extends beyond the print.
A3 for greater impact
A3 suits a statement print, a pair of coordinating designs or the main piece within a mixed gallery. Three A3 prints need considerably more width once frames and gaps are included, so calculate the complete arrangement before ordering.
Choosing wall art for above a bed
Artwork above a bed should feel visually connected to the furniture rather than floating too high or extending beyond it. Start by measuring the bed or headboard and the clear wall space above it.
Possible starting points include:
- Three A5 prints for a compact wall or low ceiling
- Three A4 prints above a typical single bed
- One A3 statement print, or three A3 prints only where the complete framed width fits comfortably
- A mixed-size arrangement for a larger feature wall
Lay the complete arrangement on the floor first. Include the outside frame dimensions and the proposed gaps, then compare the total width with the bed. For more help with arranging a set, read our guide to creating a football gallery wall.
Safety is more important than appearance. Use secure fixings suitable for the wall and frame weight. Avoid positioning heavy or glass-fronted frames where they could fall onto a sleeping child. Lightweight frames with acrylic glazing may be more suitable, but they must still be installed securely.
Choosing wall art for a nursery or above furniture
For a nursery, an adjacent wall can complement the cot without placing framed artwork directly over the sleeping area. Avoid heavy, glass-fronted or loosely secured frames above a cot, bed or play area, and keep all artwork securely fixed and out of reach.
A chest of drawers provides a natural visual anchor. Depending on the usable wall width, try one A3 print, three A5 prints, three A4 prints or a small mixed arrangement. Allow space for lamps, shelves and changing accessories, and keep the complete display visually aligned with the furniture below.
How many prints should you choose?
A set of three
Three prints are easy to balance and work particularly well above a single bed, on a wall beside a cot or above a chest of drawers. A personalised design can sit in the centre with two supporting prints on either side.
A set of six
Six prints provide more variety and can be arranged as two rows of three. This works best where there is enough width and height to leave breathing space around the complete display. Keep the row and column gaps consistent so the six frames read as one arrangement.
A set of nine
Nine prints create a fuller feature wall. They can form a regular three-by-three grid or combine different sizes for a more relaxed appearance. Before choosing a larger set, make sure the room can accommodate the complete arrangement without it feeling crowded. More prints do not always create a better result.
How much space should you leave between frames?
Consistent spacing helps separate frames while making them feel like one collection. A gap of approximately 5 to 8 cm is a useful starting point for many arrangements, rather than a fixed rule. Smaller prints may suit slightly narrower gaps, while larger frames can accommodate a little more space.
Consistency is usually more important than choosing one exact measurement. Use a tape measure and spirit level rather than judging every gap by eye. When calculating the total width, include the outside width of every frame, each gap and some open space around the complete gallery.
Do mounts change the size you need?
A frame mount creates a border around the artwork, but it also changes the size of the finished piece. For example, an A4 print may be placed inside a larger frame with a mount. Although the artwork remains A4, the complete framed piece occupies more wall space.
Check both the print opening and the frame's outside dimensions before ordering. This is particularly important when several frames must fit within a measured area. A mount and larger frame can also give a smaller print more presence and breathing space.
Matching sizes or a mixed gallery wall?
Matching frame sizes are the simplest option for a neat row or grid. They create a clean structure and make spacing straightforward.
A mixed-size gallery wall feels more informal and can help fill an awkward wall. To keep it coordinated:
- Repeat the same frame colour or material
- Use a consistent colour palette across the artwork
- Choose one larger print as the visual anchor
- Distribute smaller designs around it
- Keep the gaps reasonably consistent
Plan a mixed gallery on the floor before moving anything to the wall. Photograph the final arrangement so you can refer to it while hanging.
A simple kids' wall-art size guide
| Location | Suggested starting point |
|---|---|
| Small nursery wall | One A4 print or three A5 prints |
| Wall beside a cot | Three smaller matching prints |
| Above a single bed | Three A4 prints |
| Above a wide bed or headboard | One A3 statement print, or three A3 prints only if the full framed width fits |
| Above a chest of drawers | One A3 or three A5/A4 prints |
| Medium feature wall | Six matching prints |
| Large feature wall | Nine prints or a mixed-size gallery |
Use these combinations as starting points rather than fixed rules. Furniture width, frame dimensions, ceiling height and the amount of open wall space will all affect the final result.
Quick checklist before ordering
- Measure the clear wall space.
- Measure the furniture beneath the artwork.
- Check the exact print dimensions.
- Allow for the frame and any mount.
- Include the gaps between frames.
- Test the arrangement with paper templates.
- View the layout from the doorway and across the room.
- Choose secure fixings suitable for the wall.
- Avoid unsafe placement above a cot or sleeping area.
Frequently asked questions
Is A4 or A3 better for bedroom wall art?
A4 is a versatile option for sets and medium-sized walls. A3 creates more impact and is usually better for a single statement print or a larger room. Testing both sizes with paper templates is the easiest way to decide.
What size prints work best in a set of three?
Three A4 prints are a useful starting point above a typical single bed. Three A5 prints suit smaller spaces, while three A3 prints require a considerably wider wall.
Should every print in a gallery wall be the same size?
No. Matching sizes create a structured display, but mixed sizes can also work well. Use consistent frames, colours or artwork styles to connect the different pieces.
Do I measure the print or the frame?
Measure the complete outside dimensions of the frame when planning the wall. The frame and mount can make the finished piece significantly larger than the print.
How do I calculate the width of three framed prints?
Add the outside width of all three frames and two gaps. For example, if each frame is 25 cm wide and each gap is 6 cm, the complete row will be 87 cm wide.
Choose a size that suits your room
The best wall-art size is not simply the largest option that fits. It is the size that feels balanced with the furniture, leaves enough open space and allows the artwork to be enjoyed clearly.
Measure first, test the arrangement with paper templates and consider the complete framed size before ordering. A little planning will help you create a children's gallery wall that feels considered, personal and easy to update.
