Gallery walls look effortless when they’re done well — and that’s exactly why they’re hard. The secret is math: consistent spacing, a total width around two-thirds of the wall, and everything centered at 57″. Our free gallery wall calculator does that math for your wall, your frame size and your layout style — just enter your measurements and let the gallery wall calculator plan the arrangement.

What the Gallery Wall Calculator Tells You (Specifications)

• Inputs: wall width in inches, frame size (8×10, 11×14 or 16×20), and layout (grid or salon).
• Frame count and arrangement — e.g. 3 across x 2 down for a grid, more frames for a salon spread.
• Total span width — targeted at ~66% of your wall width, the designer’s proportion.
• Spacing — 2.5″ between frames for grids, 3.5″ for salon layouts.
• Hanging height — arrangement centered at 57″ from the floor (gallery standard), or 6–8″ above furniture.

How to Use It — Step by Step

1. Measure your wall width in inches.
2. Pick your frame size — or the size most of your frames are.
3. Choose grid or salon. Grid is formal and calm; salon (eclectic) is collected and personal.
4. Hit calculate and note the frame count, span and spacing.
5. Mock it on the floor first with painter’s tape outlines, then transfer to the wall — never nail blind.

Designer Tips for Gallery Walls

• Consistent gaps make it look professional. The spacing number the calculator gives you is the whole game — don’t eyeball it.
• 57″ center is museum standard — the average human eye level. Over a sofa, start 6–8″ above the back.
• Limit frame finishes to two. Mixed art is charming; mixed frame finishes in five finishes is chaos.
• Include one oversized anchor piece in salon layouts — it gives the eye a place to land.

FAQs

How far apart should gallery wall frames be?
2–3″ for tight grids, 3–4″ for salon layouts. Consistency matters more than the exact number.

How high should a gallery wall be hung?
Center the whole arrangement at 57″ from the floor — that’s gallery standard.

How many frames for a gallery wall?
It depends on wall width and frame size — a 10 ft wall with 11×14 frames typically takes 6–9. Run your wall through the calculator.
