Frame Sizes for Gallery Walls
Total width decides the frames, not the other way round. Here are the combinations that actually add up.
By Janet H. · Published
Work out the total width first — two-thirds to three-quarters of the furniture below — then pick the frame sizes that add up to it, gaps included. Doing it the other way round is how people end up with five frames that cover half the wall they were meant to fill.
An 84 inch sofa needs 56 to 63 inches of arrangement. That is three 16x20 frames at 3 inch gaps (54 in), or four 11x14 frames (53 in), or a 20x24 anchor with satellites.

The arithmetic
Total width = (frame width × number of frames) + (gap × number of gaps). There is always one fewer gap than there are frames.
Three 16x20 frames at 3 inch gaps: (16 × 3) + (3 × 2) = 48 + 6 = 54 inches.
Four 11x14 frames at 3 inch gaps: (11 × 4) + (3 × 3) = 44 + 9 = 53 inches.
Combinations by target width
| Target width | Furniture it suits | Combination | Actual total |
|---|---|---|---|
| 25-30 in | Narrow console, between doors | Two 11x14 portrait, 3 in gap | 25 in |
| 30-36 in | 48 in console | Three 8x10 portrait, 3 in gaps | 30 in |
| 36-40 in | Small sideboard | Two 16x20 portrait, 3 in gap | 35 in |
| 40-45 in | Queen headboard (60 in) | Three 11x14 landscape, 3 in gaps | 48 in |
| 50-57 in | King headboard (76 in) | Three 16x20 portrait, 3 in gaps | 54 in |
| 56-63 in | 84 in sofa | Three 16x20 portrait, 3 in gaps | 54 in |
| 56-63 in | 84 in sofa | 20x24 anchor + four 11x14, 3 in gaps | 48 in wide, 31 in tall |
| 64-81 in | 108 in sectional | Five 16x20 portrait, 3 in gaps | 92 in — too wide; use two rows |
| 64-81 in | 108 in sectional | 3x3 grid of 16x20, 3 in gaps | 54 in wide, 66 in tall |
All six standard layouts are drawn to scale with these numbers on the templates page.
What mats do to the arithmetic
Mats change the frame size, not the print size, so the arithmetic above is unaffected — you are always measuring frames. But it changes what you buy: four 8x10 prints matted into 11x14 frames come to 53 inches, where the same prints unmatted in 8x10 frames come to only 41.
That is the cheapest way to make an arrangement wider without buying larger artwork, and it is why matting keeps appearing as the answer in this section. The mat sizing chart has the step-downs.
Height matters too
An arrangement that is the right width but only 14 inches tall reads as a stripe across the wall. As a rough guide, keep the total height at least 40 percent of the total width — so a 54 inch wide arrangement wants to be at least 22 inches tall, which means portrait frames or two rows.
Then center the whole thing at 57 inches, or 6 to 8 inches above the furniture, whichever applies. The height guide and the spacing guide.
Buying to the plan
Once the combination is decided, buy the frames in one order in one finish. Frames bought months apart from different lines do not match, even when the color name is the same — and on a gallery wall that difference is visible.
The frame set roundup covers sets designed to hang together, and the general frame roundup covers lines consistent enough to reorder from.

Common questions
What size frames for a gallery wall above a sofa?
For an 84 inch sofa, target 56 to 63 inches of total width including gaps. Three 16x20 portrait frames at 3 inch gaps come to 54 inches; four 11x14 portrait frames come to 53. Where a single row overshoots, stack into two rows instead.
How do you calculate gallery wall width?
Frame width times the number of frames, plus the gap times the number of gaps — and there is always one fewer gap than there are frames. Three 16x20 frames at 3 inch gaps is 48 plus 6, which is 54 inches.
Should gallery wall frames be portrait or landscape?
Decide before doing the arithmetic, because it changes the total width by a third. An 11x14 frame is 11 inches wide portrait and 14 wide landscape. Portrait frames also give an arrangement more height, which stops it reading as a stripe.
How tall should a gallery wall be?
At least about 40 percent of its width, as a rough guide. A 54 inch wide arrangement wants to be at least 22 inches tall, which means portrait frames or two rows. Wide and shallow reads as a stripe across the wall.
Can you make a gallery wall wider without buying bigger frames?
Yes — mat the prints and step up a frame size. Four 8x10 prints in 11x14 matted frames total 53 inches, where the same prints in 8x10 frames total 41. It is the cheapest way to add scale to an arrangement.
