A stud finder is sweet for, nicely, discovering studs you may’t see. Understanding the place your studs are is essential for hanging up heavy gadgets, like mirrors or mounts for flat-screen TVs.
Studs—the picket or steel beams that your drywall is connected to—are probably the most sturdy place to sink weight-bearing anchors into drywall to make sure your wall hangings don’t fall.
Some stud finders produce other options, too, like deep scanning and AC wire detection. This helps stop you from hitting a pipe or wire when hanging one thing up—a mistake that may rapidly turn into an costly one. That doesn’t imply that stud finders work like X-ray imaginative and prescient, although—there’s quite a bit happening in partitions, and it may be onerous, regardless of advances in tech, for any system to find out what’s a pipe and what’s a wire, for example.
To check all of the options, we put a choice of the stud finders via their paces on a wall of our personal making and partitions in actual properties. We examined a number of choices to search out the very best stud finders for dwelling and industrial use, whether or not you simply want a hand hanging up your new cabinets otherwise you’re hoping to keep away from harm when you work throughout the drywall.
Greatest Stud Finders
What to Take into account
Magnetic Versus Digital Stud Finders
Magnetic stud finders work by waving the magnet alongside the wall till it catches on the fasteners that connect drywall to the studs. Since fasteners could also be spaced over a foot aside on a single stud, it could take longer to find one with a magnetic stud finder, however that is an inexpensive and easy choice.
Magnetic stud finders aren’t at all times probably the most correct, although—they depend on the fastener truly being pushed into the stud. If the builder missed the stud, so will the magnetic stud finder. In industrial development, the place steel studs are commonplace, chances are you’ll discover magnetic stud finders extra helpful.
Most digital stud finders work by sending out a sign from a sensor inside, then studying the sign that bounces again. When the sign modifications, the stud finder beeps or flashes to let it’s discovered a stud.
Some additionally determine steel pipes or electrical wires. Probably the most superior stud finders use know-how like ground-penetrating radar, which makes use of radar pulses to create a subsurface picture.
For many occasional dwelling makes use of, like hanging footage or rest room mirrors, a magnetic stud finder does the trick. If you happen to plan on hanging heavier gadgets or something that’ll bear weight, like a shelf or a motorcycle rack, you would possibly need to get an digital stud finder to be sure to’re heading in the right direction.

Stud finders have their jobs reduce out for them, given the numerous variables in wall supplies and development. When you might get definitive leads to one case, you might be left scratching your head in one other. Take every part with a grain of salt, and use the stud finder together with the location {of electrical} and plumbing fixtures to determine issues out. Scroll to the underside for extra recommendation on methods to get probably the most out of your stud finder.
How We Evaluated
For our evaluations, we constructed a four-by-eight-foot wall from widespread supplies: wooden and steel studs; drywall; copper, black, pex, and PVC pipes; and nonmetallic sheathed cable. Then, we scanned the wall with every of the stud finders.
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.

Bosch’s GMS120 is far more than a stud finder (although it did find the facilities inside an eighth of an inch). It could actually additionally detect stay AC wiring, steel objects, plastic pipes crammed with water, and even rebar in concrete. This Bosch unit has audible tones, an illuminated ring across the sensor space, and an LCD display screen—and all three work in live performance, guiding you to what you’re scanning for.
The ring turns crimson when over a stud, whereas the display screen offers live-wire alerts and shows a bull’s-eye to point the stud’s middle. Although the GMS120 didn’t discover wiring in our wall, it did choose it up pretty precisely within the take a look at homes.
This Hart Skilled stud finder is without doubt one of the greatest values on this record, if not for its 9 sensors, then for no calibration required. This system can immediately discover wooden and steel studs, and a number of LEDs detect and observe the place objects are so customers could be cautious of wires, pipes, and stay wires. Every object is tracked with lights that transfer with the system as you glide it in opposition to a wall, with crimson indicating studs and yellow displaying stay wires.
The show reveals the total width of objects with a max depth of 1.5 inches, and a built-in pencil holder makes marking issues simple. Whereas we haven’t had the prospect to check this ourselves, numerous shoppers say this Hart system is without doubt one of the greatest stud finders they’ve used, rivaling premium choices with its 9 sensors. It could actually’t detect studs in plaster partitions, however at its worth, it’s a stable worth purchase with a lot to supply.
If you happen to solely must discover a stud, Craftsman’s Hello-Vis Stud Sensor does precisely that. It’s easy and efficient, designed to find the perimeters of wooden and steel studs. Urgent the button on the aspect, we slid it slowly alongside the wall, maintaining a tally of the indicator. When it lit up, we had been on the fringe of a stud. That indicator stayed on till we handed the opposite edge, then we slid the unit again over the stud to substantiate and mark the perimeters earlier than pinpointing the middle. The instrument constantly discovered studs below drywall as much as three-quarters of an inch thick in our testing.
For locating studs, issues don’t get a lot less complicated than the StudBuddy. Utilizing it, we effortlessly situated nails, screws, or steel studs by sliding it in an “S” sample, backwards and forwards on a wall. Two robust neodymium magnets brought on the StudBuddy to snap to ferrous fasteners or studs after we received inside about three-quarters of an inch of them.
Sliding it up or down rapidly confirmed extra hits, and the situation and path of studs. We discovered it labored even higher on steel studs as a result of fewer affirmation “hits” had been required. The StudBuddy might also find different ferrous metals within the wall, like ductwork or electrical packing containers—so scanning to substantiate stud orientation is essential.
DeWalt’s DW0150 constantly discovered stud facilities, finding each wooden and steel equally nicely via each 1⁄2- and three⁄4-inch drywall. An alert within the type of an LED arrow pointed towards the studs, and we discovered that touring over the stud after which again till the DW0150 picked up the middle was almost 100% correct.
(We give DeWalt kudos, too, for together with a window within the middle, which made marking stud facilities with a pencil simple.) The system additionally detects AC wiring—it was dependable via a 1⁄2 inch of drywall however solely intermittent below the three⁄4-inch selection.
Zircon’s A200 is a robust wall scanner with three scan modes. In our testing, it discovered the studs, iron and copper pipes, and stay AC electrical wires in our wall. It was additionally very dependable and correct, detecting studs and indicating their facilities by projecting a crimson arrow on the wall. After we handed over stay wires, the display screen displayed an icon indicating the wires had electrical energy operating via them.
Whereas utilizing it in devoted metal-scan mode, we discovered it simple to distinguish between steel plumbing pipes and wooden studs. It was a little bit trickier if steel studs had been current, however realizing the stud spacing helped us type issues out.
In deep-scan mode, the A200 didn’t choose up PVC pipes within the wall until that they had water in them. We had been in a position to differentiate between pipes and studs by toggling between stud scan and deep scan. And the A200 offered all this info on its illuminated display screen.
Craftsman’s center-finding unit has LEDs to point scan standing and information you to the middle of the stud—orange ones gentle up while you’re over the stud, and crimson ones point out while you hit the middle. Scanning slowly in a single path, previous the middle, after which again received us correct outcomes over 1⁄2- and three⁄4-inch drywall.
The AC-detection mode was imprecise, indicating an space three to 4 inches huge when it picked up the wiring. However repeated passes allowed us to find out the wiring’s path. In commonplace scan mode, the Craftsman situated some copper pipe, which was odd, however the pipe was too slender to be a stud and the system by no means registered a middle.
Equally, it detected black pipe in steel mode. (Observe that though it situated the pipes, the stud finder couldn’t, nor was it designed to, determine them as such.) Nonetheless, these readings can assist you determine different objects within the wall chances are you’ll need to watch out round.
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.
