All functioned as anticipated when it got here to detecting the studs, however we rapidly discovered that a few of them didn’t work as marketed. We additionally took the stud finders to 2 properties—one, a mid-1800s home with lath and plaster, and the opposite, a Nineteen Seventies tract home—for real-world testing.
We discovered a number of stud finders that labored nice, and used our DIY and carpentry experience right here at Standard Mechanics to find out which stud finders had been greatest for numerous makes use of. We additionally advocate a couple of that we haven’t had an opportunity to check out but, however that we predict are promising based mostly on product specs and person critiques.

Stud-Discovering Ideas from Our Professional, Bradley Ford
Most studs are spaced at 16-inch intervals—discover one, and the subsequent stud ought to be about that very same distance in both path. Adjustments in spacing often occur close to the ends of partitions or doorways and home windows.
In case your stud finder appears to be selecting issues up between the studs, it could possibly be detecting steel or plastic plumbing parts, electrical packing containers or wiring, or steel ductwork. To fight this, scan above and under the purpose to make sure it continues to the ground or ceiling. If it doesn’t, it could possibly be one thing apart from a stud.
Electrical wires often run vertically on the aspect of a stud and typically horizontally between shops. If there are lighting fixtures, switches, and shops on a wall, you can also make an informed guess as to the place the wires is perhaps.
Take note of the place the kitchen and loos are, too—water provide and waste pipes for the second ground are sometimes present in partitions on the primary ground, under sinks, tubs, or showers. (Professional tip: In case your basement is unfinished, you may go down there to see the place the pipes go up on the ceiling.)
Listed below are a couple of different suggestions for locating studs each single time.
- Don’t contact the wall with both hand whereas utilizing a stud finder—this may alter its readings.
- Some stud finders must calibrate earlier than scanning, so begin away from switches, shops, or lighting fixtures.
- Apply some painter’s tape over the world you need to scan. It’ll provide you with a floor on which to mark your findings with out having to jot down on the wall.
- If you detect studs, objects, or stay wires, mark them with a pencil or tape.
- Freshly painted partitions could also be troublesome to scan for a couple of weeks because of the moisture within the paint.
