Step-by-Step Guide: What Frame Size Do I Need for my Space
by Mae Osz on Oct 24, 2024
Getting the sizing right is one of the most common challenges when it comes to displaying wall art — pick a frame that's too small and the artwork gets lost; too large and it can overwhelm the room. The good news is that a few straightforward rules make the decision much easier, whether you're hanging a single print above a sofa or building out a full gallery wall. This guide walks you through everything you need to know, from measuring your wall to matching your artwork to the right size and style.

Key Takeaways:
- Your picture mount should be 2–4 inches larger than the print on each side — a 16×20 print typically looks best in an 18×24 opening.
- Hang wall art so the centre of the piece sits 57–60 inches from the floor, which aligns with average eye level in most rooms.
- Matting adds a visual buffer between the print and frame, allows a larger frame to be used, and gives the display a more polished, gallery-like finish.
- For gallery walls, place the largest frame at the centre or as the focal point and arrange smaller frames around it with 2–3 inches of spacing between each.
- In small spaces or narrow hallways, vertical frame arrangements make the most of limited wall area without the space feeling cluttered.
- Bespoke mounting is worth considering for unusually sized, valuable, or sentimental pieces where off-the-shelf sizing won't do the artwork justice.
Choosing the right frame size enhances wall art prints and overall decor. It helps showcase the artwork effectively and contributes to the room's aesthetic appeal. However, selecting the appropriate frame size can be challenging, leading to common mistakes that affect the presentation and harmony of the decor.

The Importance of Choosing the Right Frame Size
Understanding Frame Sizes: A Quick Primer
Before getting into the selection process, it's important to understand standard frame sizes and their common uses. These sizes range from small frames (4x6, 5x7 inches) for personal photos to larger frames (18x24, 24x36 inches) for posters and art prints. Custom frame options are also available for unique art pieces, offering flexibility in design and size.
It's worth knowing that frame sizes refer to the opening — the area that shows the artwork — not the outer dimensions of the frame itself. This distinction matters when you're measuring a print and trying to match it to a frame, as the outer frame will always be larger than the stated size. Keeping this in mind from the start saves a lot of frustration when shopping.

Assessing Your Space: Measuring Walls and Available Area
Measuring Wall Dimensions Accurately
Start by measuring the wall dimensions where you plan to hang the art. Use a tape measure to get the height and width and note any architectural features or obstructions.
It's also helpful to note the wall's relationship to the room — a wall behind a sofa, for example, has different framing needs than a standalone feature wall. Taking a photo of the space alongside your measurements gives you a useful reference when comparing frame sizes later.
Considering Furniture Placement and Wall Space Proportions
Consider the placement of furniture and the proportions of the wall space. Ensure that the frame size complements the furniture arrangement and doesn't overwhelm or underutilise the wall area.
A common rule of thumb is that wall art above a sofa or bed should span roughly two-thirds of the furniture's width. This proportion creates a natural visual connection between the art and the piece below it, making the arrangement feel intentional rather than accidental.
How to Choose the Right Size for Your Wall Art
Selecting Art Prints, Determining Print Sizes and Their Impact
Choosing the Right Size for Different Types of Art Prints
When selecting art prints, consider the type of artwork. Photography, paintings, and posters each have ideal sizes that enhance their visual impact.
Photography tends to work well in standard sizes like A3 or A2, which are easy to mount without cropping. Illustrated prints and posters often suit slightly larger formats where the detail can breathe — browse our wall art prints for living rooms to find options in a range of ready-to-hang sizes. If you're unsure, ordering a test print at a smaller size first lets you check the composition before committing to a larger version.
Considering the Visual Weight and Impact of Art Prints
Evaluate the visual weight of the art print. Larger prints make bold statements, while smaller prints can be part of a cohesive gallery wall. Balance the size to match the desired visual impact in the room.
A print with a lot of negative space or a minimal composition can carry a larger frame without feeling lost, whilst a busy, detailed print may actually read better at a smaller size where the eye can take it all in comfortably. Thinking about the artwork's visual density — not just its physical dimensions — helps you make a more confident sizing decision.

General Sizing Guidelines and Proportions
Guidelines for Selecting Frame Sizes Relative to Art Prints
As a rule of thumb, the frame should complement the art print without overshadowing it. For instance, a 16x20 print typically looks best in an 18x24 frame.
If you're working with metric sizes, an A4 print (21x29.7cm) suits an A3 frame with a mat, whilst an A3 print works well in an A2 frame. The extra space created by the larger frame gives the artwork room to breathe and makes the overall display feel more considered and gallery-like.
Using Matting to Adjust the Overall Size and Visual Impact
Matting can enhance the artwork's presentation and allow for a larger frame size. It creates a visual buffer and adds sophistication to the display.
White or off-white mats are the most versatile choice and work with almost any print. A wider mat border — around 3–4 inches — gives a more premium, museum-quality feel, whilst a narrower mat keeps things clean and modern. The mat colour can also be used to pick out a tone from within the artwork itself, subtly tying the whole display together.

Creating a Gallery Wall: Mixing and Matching Frame Sizes
Planning a Cohesive Layout with Various Frame Sizes
When creating a gallery wall, plan a layout that harmoniously mixes and matches different frame sizes. Sketch the arrangement on paper or use templates to visualise the layout.
A good starting point is to lay all your frames on the floor first and experiment with arrangements before committing to the wall. This lets you see how the sizes interact and spot any imbalances before you pick up a hammer. Taking a photo of the floor layout also gives you a reference to work from when hanging.
Tips for Balancing Different Sizes and Shapes
Balance is key in a gallery wall. Arrange larger frames at the centre or as focal points and surround them with smaller frames to create a balanced composition.
Mixing portrait and landscape orientations adds visual rhythm and prevents the wall from feeling too rigid. If you're using frames in different finishes — black, wood, and white, for example — keeping one consistent element like frame width or mat colour helps the arrangement feel cohesive rather than chaotic.

Testing and Visualization: Tools and Techniques
Using Paper Templates to Visualise Frame Placement
Cut out paper templates in the sizes of your frames and tape them to the wall. This helps visualise the placement and spacing before hanging the actual frames.
Use painter's tape rather than regular tape so you don't mark the wall. Leave the templates up for a day or two and observe how they look in different lighting conditions — morning light and evening light can make the same arrangement feel very different, and it's worth checking both before committing.
Digital Tools and Apps for Visualising Frame Sizes on Your Wall
Several digital tools and apps allow you to upload photos of your wall and overlay different frame sizes. This technology aids in making informed decisions about frame placement and size.
Apps like IKEA Place or Houzz use augmented reality to show how frames will look in your actual space. Even a simple photo editing tool where you paste in frame outlines to scale can save a lot of time and second-guessing before you start putting holes in the wall.

Considering Frame Style and Width: Enhancing the Art and Space
Selecting Frame Styles That Complement Your Decor
Choose frame styles that align with your room's decor. Modern spaces might benefit from sleek, minimalistic frames, while traditional rooms might look better with ornate, classic frames.
Natural wood frames are one of the most versatile options — they work equally well in Scandi, rustic, and contemporary interiors. Black frames are a reliable choice for a clean, graphic look, whilst white frames keep things light and airy. When in doubt, matching the frame finish to another element already in the room — a lamp base, a furniture leg — creates an easy sense of cohesion.
Choosing Frame Widths Based on Art Size and Type
The width of the frame should also be considered. Thicker frames can provide a bold outline for large pieces, while thinner frames are suitable for smaller or more delicate artworks.
As a general guide, frames under 1 inch wide suit small prints and photographs, whilst frames of 2–3 inches work well for medium to large canvases. Very wide frames — 4 inches or more — can make a statement on their own and work best when the artwork inside is bold enough to hold its own against the frame's presence.

Placement and Spacing: Ensuring Proper Arrangement
Ideal Heights for Hanging Art Based on Room Function
The ideal height for hanging art is typically at eye level, about 57–60 inches from the floor to the artwork's centre. Adjust based on room function and viewer's height.
In dining rooms and other spaces where people are usually seated, drop the hanging height slightly — around 54–57 inches — so the art reads well from a seated position. In hallways where people are always standing and moving, the standard 57–60 inch rule works well and keeps the display feeling consistent as you walk through.
Spacing Between Frames for a Balanced Look
Maintain consistent spacing between frames for a cohesive look. A gap of 2–3 inches between each frame is generally recommended.
For a tighter, more editorial feel — similar to a professional gallery — reduce the gap to 1.5 inches. For a more relaxed, eclectic arrangement, slightly wider gaps of 3–4 inches give each piece more breathing room. The key is consistency: whatever spacing you choose, keeping it uniform across the arrangement makes the whole display look deliberate.

Special Considerations: Large Walls, Small Spaces, and Unique Areas
Tips for Framing Art on Large, Blank Walls
For large walls, consider using oversized frames or creating a gallery wall to fill the space without it looking sparse.
A single oversized print — anything above 24x36 inches — can anchor a large wall confidently on its own. If you prefer a gallery arrangement, aim for a total grouping width that covers at least half the wall's width, otherwise the display can look lost in the space.
Strategies for Small Spaces and Narrow Walls
Opt for smaller frames or vertical arrangements in small spaces or narrow walls to make the most of the limited area.
In a narrow hallway, a single column of vertically stacked frames draws the eye upward and makes the ceiling feel higher. Keeping all frames the same width in this arrangement creates a clean, intentional look that works particularly well in modern or minimalist interiors.
Framing Solutions for Unique Spaces Like Staircases and Hallways
For staircases and hallways, follow the angle of the stairs for frame placement or use a linear arrangement to guide the eye along the space.
When following the staircase angle, keep the bottom edges of the frames parallel to the stair line rather than the floor — this creates a flowing, intentional diagonal that feels designed rather than accidental. Spacing frames about 6–8 inches apart vertically gives enough breathing room whilst maintaining the sense of movement up the stairs.

Custom Sizing: When Standard Options Won't Do
Benefits of Custom Framing for Special Art Pieces
Custom framing allows for precise sizing and unique frame choices that standard sizes can't provide. This is ideal for valuable or unusually sized art pieces.
It's also worth considering custom framing for sentimental pieces — a child's drawing, a vintage map, or a print from a meaningful trip — where the framing itself becomes part of the story. A professional framer can advise on archival materials that protect the artwork from UV light and humidity, which matters more for pieces you intend to keep for decades.
Working with Professional Framers
Consult with professional framers to explore options and ensure the best framing solutions for your artwork.
Most professional framers will let you bring in the artwork and hold different frame samples against it before committing. This hands-on process is far more reliable than choosing online, where colours and finishes can look very different on screen. It's worth the extra step, especially for pieces you plan to display prominently.

Maintenance and Care: Preserving Your Framed Art
Tips for Cleaning and Protecting Frames and Art Prints
Regularly dust frames and clean glass with appropriate cleaners. Avoid direct sunlight to prevent fading.
For wooden frames, a dry microfibre cloth is usually sufficient — avoid damp cloths which can warp the wood over time. For glass, use a specialist glass cleaner sprayed onto the cloth rather than directly onto the frame, which prevents liquid from seeping behind the glass and damaging the print.
Ensuring the Longevity and Quality of Framed Pieces
Rotate art prints to prevent prolonged exposure to light and moisture. Use archival materials for long-lasting preservation.
If you notice any yellowing of the mat or print over time, it's likely the materials weren't acid-free. Replacing the mat with an archival-quality version is a straightforward fix that can significantly extend the life of the artwork without needing to reframe the whole piece.
Selecting the Perfect Frame Size for Your Space
Choosing the right frame size enhances the visual appeal of your art and complements your decor. Following these steps and tips, you can create a balanced, personalised display highlighting your unique style. Embrace experimentation and let your creativity guide you in achieving the perfect framing solutions for your space.

Why Getting Your Frame Size Right Matters
The sizing of a picture mount affects far more than aesthetics — it shapes how a room feels. An undersized display on a large wall creates dead space and makes the art look like an afterthought, while an oversized piece in a compact room can feel oppressive rather than impactful.
Research into interior design consistently shows that proportionally matched artwork increases the perceived value of a room. When your wall art sits in the right-sized mount, hung at the correct height, it anchors the space and gives it a finished, intentional quality. That is the difference between a room that looks styled and one that looks decorated.
Understanding the basic principles before you shop also saves money — returns and re-orders from getting the sizing wrong are one of the most common frustrations buyers report. A few minutes of measuring and calculation upfront means you get it right first time.
Standard Frame Sizes at a Glance
Most off-the-shelf mounts follow standard sizing conventions that align with common print dimensions. Knowing these before you buy makes it much easier to match artwork to housing without needing custom work.
Small formats (4×6, 5×7, 6×8 inches): Best suited to personal photographs, postcards, and small illustrative prints. Often used in grouped or shelf displays rather than as standalone wall pieces.
Medium formats (8×10, 11×14, A3): The most versatile range for art prints, photography, and typographic pieces. Works well in most room sizes as a single hanging or as part of a paired arrangement.
Large formats (16×20, 18×24, A2): Ideal as statement pieces above sofas, beds, or on feature walls. At this size, matting becomes particularly important to prevent the print from feeling cramped inside the mount.
Oversized formats (24×36 inches and above): Best used on large uninterrupted walls where the piece can serve as a true focal point. Requires careful hanging — use two wall fixings rather than one to distribute the weight safely.
