Gallery Wall Spacing Calculator
A row of frames lives or dies by its spacing, and eyeballing it is how walls end up with extra nail holes. This calculator takes your wall width, frame size, and frame count, and returns the exact center position of every frame, measured from the left edge of the wall. Tape, mark, hang, done.
How to use the positions
Each result is the distance from the LEFT edge of your wall to the CENTER of a frame. Mark those points with painter's tape at your chosen height, check the row with a level, and hang. For the vertical position, keep every frame's center at 57 inches on an open wall, or use the hanging height calculator for the exact nail height with your hardware. Planning a full arrangement rather than one row? Start with the free gallery wall templates and use this calculator to adapt a layout to your wall's width.
Frequently asked questions
How much space should be between frames on a gallery wall?
Two to three inches (5 to 8 cm), kept identical between every pair of frames. Tighter reads as one artwork; wider than four inches starts to read as separate pieces.
Fixed gap or evenly spread: which should I use?
Fixed gap (2 to 3 inches) is the gallery look and works over furniture. Evenly spread suits long empty walls and hallways, where equal margins at both ends make the row feel architectural, like a museum corridor.
What if my frames are different widths?
Run the calculator with the average width to rough in positions, then adjust so the GAPS stay equal rather than the centers. Equal gaps are what the eye reads; the centers can drift.
