These positions are measured from the left wall. Use a tape measure from the left edge of your available wall space. Mark each frame's centre position, then use the single-frame calculator to find nail heights.

How to Use This Calculator

  1. 1

    Measure your wall space

    Measure the available width of your wall section. For grid layouts, also measure the available height.

  2. 2

    Enter frame details

    Input the frame width (and height for grids) plus the number of frames you want to hang.

  3. 3

    Set spacing (optional)

    Enter a custom gap between frames, or leave it empty and the calculator will find the optimal even spacing automatically.

  4. 4

    Read the positions table

    Each frame’s left edge and centre position is measured from the left wall. The centre position is where your nail goes.

  5. 5

    Mark and hang

    Transfer the measurements to your wall with a tape measure, then use the single-frame calculator to find the nail height for each frame.

Frequently Asked Questions

What's the ideal spacing between gallery wall frames?

For most gallery walls, 50-75mm (2-3 inches) between frames works well. Tighter spacing (25-50mm) creates a cohesive, modern look, while wider spacing (75-100mm) gives each piece more visual breathing room. This calculator automatically finds the optimal spacing based on your wall and frame sizes.

Should spacing be equal all around?

For grid layouts, yes - consistent spacing creates visual harmony. This calculator ensures equal horizontal spacing between frames and equal margins on the sides. For salon-style arrangements, you can vary the spacing slightly, but keep it within a range (e.g., 40-60mm) for coherence.

How much wall space should I leave as margin?

Leave at least 100-200mm (4-8 inches) from edges like corners, doors, or furniture. The wall margins calculated by this tool ensure your gallery is centred with appropriate breathing room. If the calculated margin seems too small, consider using fewer frames or a narrower wall section.
