Wall art size calculator: what size art do I need?

Art that is too small is one of the most common styling mistakes. Tell us what the art will hang above and how you want to arrange it, and we will work out the sizes, the spacing and the hanging height.

For a bare wall, enter the wall width.
Top of the sofa back or headboard.

The two thirds rule for wall art

Art above furniture looks best when it spans about two thirds to three quarters of the furniture's width. Above an 84 inch sofa, that means art between 56 and 63 inches wide, whether it is one large canvas, a pair or a gallery of smaller frames. Go much smaller and the art looks like it is floating; go wider than the furniture and the wall feels top heavy.

On a bare wall with nothing below, aim for about half to 60 percent of the wall width, and center the piece at eye level, which galleries set at 57 to 60 inches (145 to 152 cm) from the floor.

How high to hang art

AboveGap to the frameWhy
Sofa8 to 10 in (20 to 25 cm)Close enough to connect, high enough to avoid heads
Bed6 to 10 in (15 to 25 cm) above the headboardKeeps the art part of the bed wall
Console or sideboard6 to 12 in (15 to 30 cm)Leaves room for lamps and objects
Bare wallCenter at 57 to 60 in (145 to 152 cm)Average eye level, used by galleries
Use paper templates. Cut kraft paper to the size of each frame, mark where the hook sits, and tape them to the wall. You can shuffle them around for free before a single hole goes in.

Pairs, triptychs and gallery walls

When you hang more than one piece, treat the whole group as one unit. The total width follows the two thirds rule, and the gaps between frames stay consistent, usually 2 to 3 inches (5 to 8 cm). Tighter spacing makes a group feel like one statement, while wider gaps make each piece stand alone. Triptychs work beautifully above long sofas and beds, and gallery grids suit hallways and staircases.

Standard frame sizes include 11 x 14, 16 x 20, 18 x 24, 24 x 36 and 30 x 40 inches, or 30 x 40, 50 x 70 and 70 x 100 centimeters. The calculator suggests the standard size closest to your ideal so you can shop ready made frames.

Frequently asked questions

What size art should go above an 84 inch sofa?
Between about 56 and 63 inches wide in total. That could be one 40 x 60 inch canvas hung landscape, a pair of 24 x 30s or three 16 x 20s with 2 to 3 inch gaps.
How high should art be hung above a sofa?
Leave 8 to 10 inches between the top of the sofa back and the bottom of the frame.
What is the 57 inch rule?
Galleries hang art so its center sits 57 inches from the floor, roughly average eye level. It is a good starting point for any wall without furniture below.
How far apart should frames be in a gallery wall?
Keep 2 to 3 inches (5 to 8 cm) between frames, and keep the spacing the same throughout so the group reads as one piece.
