Sawtooth Hanger vs Picture Wire
The fitting on the back of the frame decides whether you can straighten the picture after it is up. That is the whole comparison, and almost nobody checks it before buying.
By Janet H. · Published
Use a sawtooth for anything small and light that you want sitting flat against the wall. Use a wire for anything heavy, wide, or hung where you will want to nudge it level later — a wire slides on the hook, and a sawtooth does not.
The adhesive versions of both exist and carry published ratings: 3M rates the Command Sawtooth Sticky Nail Hanger at 5 lb and the Sticky Nail Wire-Back Hanger at 8 lb, neither of which puts a nail into the wall.

What each fitting actually does
All three fittings put the frame on a hook. The difference is where the load point sits and whether it can move once it is there.
| Fitting | Load point | Sits flush? | Can you slide it level? |
|---|---|---|---|
| Single sawtooth | One fixed point at the top rail | Yes — the frame lies flat | No, only within the width of the teeth |
| Two sawtooth hangers | Two fixed points near the top corners | Yes | No — the hook spacing has to be right first time |
| Wire across D-rings | Wherever the hook catches the wire | No — the top tilts away slightly | Yes, freely along the wire |
| Two hooks under one wire | Two points, wire spread between them | Closer to flush than a single hook | Partly — and it resists rotating |
| Keyhole slots | Two fixed points, recessed into the frame | Yes, the flattest of all | No — spacing must be exact |
When to use a sawtooth
Small, light frames hung on their own. Anything up to around 11x14 with plexiglass glazing is squarely in sawtooth territory, and most frames that size ship with one already fitted.
The sawtooth also wins anywhere the frame has to sit truly flat: beside a door frame, on a narrow wall, or in a tight grid where a tilted frame is visible against its neighbors. A gallery wall of sawtooth-hung frames looks tidier than the same wall on wires, for exactly this reason — gallery wall layouts and spacing covers the geometry.
Its limit is weight and width. A single centered load point on a wide frame puts all the stress on the middle of the top rail, which is the weakest part of a mitered frame. Above a few pounds, or past about 20 inches wide, move to two fixings.
When to use a wire
Heavy frames, wide frames, and anything you expect to straighten. A wire spreads the load into two D-rings mounted on the side rails rather than the top rail, which is structurally the right place for it, and it lets the frame slide horizontally on the hook for as long as it hangs there.
Fit the D-rings about a third of the way down from the top of the frame, and set the wire tension so that when pulled up it stops two to three inches below the top edge. Too slack and the frame leans badly; too taut and the wire pulls the side rails inward.
The two-hook measurement, step by step
Two fixings is the right answer for most frames and the reason people avoid it is the arithmetic. It is four steps.
One. Decide the height of the center of the picture. The convention is 57 inches from the floor — how high to hang art covers the exceptions for sofas, beds and stairs.
Two. Add half the frame height to that number. That is where the top of the frame will sit. On a frame wider than about 16 inches, do this for two fixings rather than one — hanging a picture with two hooks has the spacing table and the tape-transfer trick.
Three. Pull the wire taut toward the top of the frame and measure from the top edge down to the wire. Subtract that from the top-of-frame number. That is the hook height.
Four. Mark the two hook positions at that height, each about a quarter to a third of the frame's width in from its edges, and check them against each other with a level.
For a sawtooth frame, steps three and four become: measure down from the top edge to the sawtooth, and that is the hook height. Two sawtooth hangers need their spacing transferred to the wall exactly, which is why a strip of masking tape pressed across both hangers and then stuck to the wall is the standard trick.
Doing all of this without a nail
Both fittings have an adhesive equivalent, and the ratings are published. The Command Sawtooth Sticky Nail Hanger is rated 5 lb and suits frames with a sawtooth on the back. The Sticky Nail Wire-Back Hanger is rated 8 lb and suits wire-back frames. Both use an adhesive base with no nail driven into the wall, and both remove with a stretch-release tab.
The third route bypasses the frame fitting entirely. Adhesive picture-hanging strips bond directly to the back of the frame and hold it flat against the wall with no hook at all — which also means no fitting to match and no rotation. 3M rates the Large size at 4 lb per set and up to 16 lb using four pairs. Adhesive hooks versus adhesive strips compares the two approaches, and best picture hanging strips maps the sizes to frames.
Above adhesive weight, the lowest-damage option with a real hook is a drywall hook — see hanging pictures without studs.

Common questions
Is a sawtooth hanger better than picture wire?
They fail in opposite directions. A sawtooth holds the frame flat against the wall but fixes its position, so it cannot be slid level after the hook is in. A wire lets the frame slide and spreads the load into the side rails, but the hook passing under the wire tilts the top of the frame away from the wall.
How do you hang a picture with two sawtooth hangers?
Transfer the spacing rather than measuring it. Press a strip of masking tape across both hangers so their positions are marked on the tape, stick the tape to the wall at the right height, check it with a level, and put the hooks in through the marks. Measuring each one separately is where the errors come from.
How far down should picture wire be?
Fit the D-rings about a third of the way down from the top of the frame, and set the wire so that when pulled taut toward the top it stops two to three inches below the top edge. Too slack and the frame leans badly off the wall; too taut and the wire pulls the side rails inward over time.
Should you hang a picture on one hook or two?
Two, almost always. A single hook lets the frame rotate out of level every time the wall is knocked, and it puts the whole load on one fixing. Two hooks spaced about a third of the frame's width apart stop the rotation and halve the load each one carries.
Can you hang a sawtooth or wire frame without nails?
Yes, and both have rated adhesive equivalents. 3M rates the Command Sawtooth Sticky Nail Hanger at 5 lb and the Sticky Nail Wire-Back Hanger at 8 lb, each with an adhesive base rather than a nail. Alternatively, adhesive picture-hanging strips bond to the frame back and bypass the fitting entirely.
