Gallery Wall Spacing Calculator
Turn a wall width and a handful of frames into an even, centered row — with the exact spot to mark each frame's center, so the whole line goes up straight the first time.
Even spacing is what makes it look intentional
A row of pictures reads as considered when the gaps are equal and the whole group is centered on the wall. The hard part is doing that arithmetic on a ladder. Enter your numbers here first and you walk to the wall with the row width, the side margins, and a center mark for every frame already worked out.
Once the row is placed, set every hook to the same height with the Picture Hanging Height Calculator, or size the art to the furniture below it with the Frame Size for Wall Calculator.
Frequently Asked Questions
How much space should be between framed pictures?
For frames meant to read as one arrangement, 2 to 5 inches between them works well — closer for smaller pieces, a little wider for large ones. Under about 2 inches they look cramped; much beyond 5 and the eye stops grouping them and starts seeing separate pictures. The tool lets you set the gap you want, then shows the total width and the even gap that would instead spread the frames across the whole wall.
How do I center a row of frames on the wall?
Add up the frame widths plus the gaps between them to get the row width, subtract that from the wall width, and split the leftover in two — that's the empty margin on each side. The tool does this for you and returns the side margin, then gives the exact center position of every frame measured from the left edge of the wall so you can mark hooks without re-measuring each one.
What's the difference between the fixed gap and the even gap?
The fixed gap is the space you choose to put between neighboring frames, keeping the row tight in the middle of the wall. The even gap instead divides all the leftover wall space into equal parts before, between, and after the frames, so the frames are distributed evenly edge to edge. Use the fixed gap for a centered cluster; use the even gap when you want the row to span the full wall.
Should every frame be the same size?
This calculator assumes a single row of equal-width frames, which is the easiest arrangement to get right and reads as clean and deliberate. For mixed sizes, keep the vertical centers on one line and treat the gap as the space between frame edges. If you want a rectangular block of identical frames instead, the salon-wall grid tool plans rows and columns together.
Estimates for planning only. Double-check frame widths and your wall measurement before marking hooks.
