Gallery Wall Generator

Design a gallery wall layout with real frame sizes and spacing.

Use the Gallery Wall Generator

Use the gallery wall calculator to organize frame sizes and gaps inside a defined wall area. Planning the overall composition first makes it easier to maintain consistent visual spacing while accommodating different frames.

Open the interactive calculator to enter your measurements and generate a project plan.

Start with an outer boundary

Measure the wall area the arrangement should occupy, taking nearby furniture, switches, sconces, and door swings into account. Treat that rectangle as the composition boundary.

Record each frame's outside dimensions, including the frame itself. Artwork dimensions alone will produce incorrect gaps.

Plan visual spacing

Keep the visible gaps between frame edges consistent where possible. Mixed sizes can still feel orderly when rows, columns, or centerlines align.

Arrange templates on the floor or tape paper rectangles to the wall. View the group from the primary seating or entry position before making holes.

Convert frame positions to hook positions

The top of a frame is not the hanging point. Measure the tightened wire rise or hardware offset on every frame, then transfer that distance from the planned frame edge.

Use anchors suitable for the wall and frame weight. Mark each hook from shared horizontal and vertical references rather than from the previously hung frame.

Group width

sum of frame widths in a row + sum of gaps between them

Center the completed group width in the available wall area, then locate each frame within it.

Frequently asked questions

Should I round gallery wall measurements?

Enter the measurements you can verify, then keep the calculator's more precise result while laying out the project. Marking from one reference edge prevents small rounding differences from accumulating.

Should I measure in more than one place?

Yes. Walls, ceilings, and cabinets are rarely perfectly square. Measure at both ends and near the center, then plan around the tightest usable dimension.

What is the best gap between frames?

There is no single required gap. Pick a gap that is clearly intentional, test it with the real frame profiles, and apply it consistently across the composition.
