A Gallery Wall Calculator helps you plan an evenly spaced row of frames on a wall. Enter the wall width, the width of each frame, and the number of frames to calculate the total available spacing and the space between each frame.
This tool is useful for arranging artwork, photographs, posters, certificates, and decorative frames in a clean, balanced layout.
What Does the Gallery Wall Calculator Calculate?
The calculator uses:
- Wall width
- Frame width
- Number of frames
It returns:
- Total spacing available
- Spacing between each frame
For accurate results, use the same measurement unit for the wall width and frame width.
How to Calculate Gallery Wall Spacing
Step 1: Measure the Wall Width
Measure the width of the wall section where you plan to hang the frames.
Step 2: Measure the Frame Width
Measure the width of one frame, including its outer edge.
Step 3: Enter the Number of Frames
Enter the total number of equally sized frames you want to arrange in one row.
Step 4: Calculate Total Frame Width
Multiply the width of one frame by the number of frames.
Total Frame Width=Frame Width×Number of Frames
Step 5: Calculate Total Spacing
Subtract the total frame width from the wall width.
Total Spacing=Wall Width−Total Frame Width
Step 6: Calculate Spacing Between Each Frame
Divide the total spacing by the number of gaps between frames. The number of gaps is one less than the number of frames.
Spacing Between Each Frame=Number of Frames−1Total Spacing
This calculation is designed for frames arranged in one horizontal row without outside margins.
Example Calculation
Suppose you have the following measurements:
- Wall width: 120 inches
- Frame width: 10 inches
- Number of frames: 5
Calculate Total Frame Width
Total Frame Width=10 in×5=50 in
Calculate Total Spacing
Total Spacing=120 in−50 in=70 in
Calculate Spacing Between Each Frame
Spacing Between Each Frame=5−170 in=17.5 in
Each frame should be spaced 17.5 inches apart.
Gallery Wall Planning Tips
- Use the same unit for wall and frame measurements.
- Measure the outside width of each frame.
- Keep the spacing consistent for a balanced appearance.
- Use painter’s tape or paper templates to preview the arrangement before hanging frames.
- Consider the centre point of the wall when positioning the layout.
- Leave extra room at the sides if you want visible outside margins.
Frequently Asked Questions
How much space should I leave between gallery wall frames?
The ideal gap depends on your style and the frame size. Many gallery walls use a smaller, consistent gap, but this calculator shows the spacing required to distribute the frames evenly across the entered wall width.
Does this calculator include outside wall margins?
No. The spacing-between-frames result uses the space between frames only. If you want equal margins at both ends of the wall, plan those margins separately.
Can I use different-sized frames?
This calculator is best for frames with the same width. For different-sized frames, add the widths of all frames together, subtract that total from the wall width, and divide the remaining space by the number of gaps.
What happens if the frames are wider than the wall?
If the combined frame width is greater than the wall width, the frames will not fit in one row. Use fewer frames, choose narrower frames, or arrange them in multiple rows.
Can I use feet, metres, inches, or centimetres?
Yes. Use any supported measurement unit, but make sure the wall width and frame width are entered in the same unit.
Can I use this calculator for one frame?
Yes. The calculator can show the remaining wall space, but there is no spacing between frames when only one frame is used.
