Gallery Wall Layout & Hanging Height Calculator

Enter your frames, spacing, and the furniture the arrangement sits above. You get a to-scale diagram and the exact measurements to hang everything right the first time — no extra nail holes. All math runs in your browser; nothing is sent anywhere.

Your arrangement

Most gallery walls use 3–9 pieces (max 12 here).

Designers keep this at 2–3 in.


Furniture below (optional)

Height of the top of the sofa back, console, headboard, or table from the floor. Leave both blank to plan against a bare wall.

To-scale layout

Drawn to scale from your numbers. Dashed line = the center height of every frame.

Your hanging plan

    Where these numbers come from

    Every output is plain geometry and arithmetic applied to the dimensions you enter, using four long-established interior-design conventions — not opinions or invented data:

    • 57 in eye-level height — the "museum height" standard for centering art at average eye level.
    • 2–3 in spacing between frames so the pieces read as one group.
    • 60–75% of the furniture width for a balanced, proportional arrangement.
    • 6–8 in clearance between the bottom frame and the furniture top.

    These are the same guidelines detailed in our Gallery Wall Layout Ideas guide. When you add a furniture height, the tool keeps the arrangement as close to 57 in as possible while still meeting the 6–8 in clearance rule, and tells you whenever it adjusts.
