How to hang a picture perfectly straight
Updated July 3, 2026 · 15-minute job
A crooked frame is the kind of thing you stop seeing — until a guest tilts their head at it. Hanging pictures well is really two problems: the right height, and dead level. Your phone solves the second one outright, and helps with the first.

Step by step
- Pick the height — use the 57-inch rule. Galleries hang art with the center of the piece at about 57" (145 cm) from the floor: average eye level. Over a sofa or sideboard, go lower — bottom edge of the frame 6–10" above the furniture, so the two read as one unit.
- Find the true hanging point. The hook doesn't go where the top of the frame goes. Pull the hanging wire taut toward the top and measure the drop from the frame's top edge to the wire's peak. Your wall mark = desired top-of-frame height minus nothing, but the hook goes that drop-distance below it. For sawtooth and keyhole hangers, measure to the hanger itself.
- Wide frame? Use two hooks. This is the single best trick in this guide: a frame hanging on one point pivots forever; on two points it can't. Mark two hook positions, then check the line between the marks is level — hold a straightedge across them and rest your phone on it in edge mode, or measure both marks up from the floor.
- Tricky multi-hole frames: the tape template. Stick painter's tape across the back of the frame, mark the hole positions on it, then move the tape to the wall. Level the tape (phone on its edge along the tape line), then drill straight through the marks. Zero guesswork.
- Mount the hardware. Plain nails are fine for small frames; use drywall anchors above ~10 lbs and studs (or rated anchors, two points) for mirrors and anything heavy.
- Hang, then check like a pro. Rest your phone's long edge on top of the frame in edge mode. Nudge until it reads 0.0°. This beats eyeballing every time — walls, ceilings and furniture lines are often not straight, which is exactly what fools your eye.
- Make it stay straight. Stick small rubber or felt bumpers on the two bottom corners — they grip the wall and protect the paint. In high-traffic spots (hallways, near doors), a pea-sized blob of museum putty locks the frame in place.
Gallery walls: keep 2–3" between frames, everywhere. Align the tops of each row and check the row with the level. Consistent gaps read as intentional even when frame sizes vary wildly.
FAQ
What height should pictures be hung?
Center of the artwork at ~57" from the floor; lower over furniture (bottom edge 6–10" above it).
How do I stop a picture tilting sideways?
Two hooks instead of one, bumpers on the bottom corners, museum putty where there's vibration.
Can I do this without buying a spirit level?
Yes — this free level runs in your phone's browser. Edge mode is made for exactly this: stand the phone on the frame's top edge and zero it out.
How far apart should gallery-wall frames be?
2–3 inches, kept consistent across the whole arrangement.
What about heavy mirrors?
Studs or rated anchors, always two mounting points — for safety and so it can't rotate off level.
