When it’s time to hang or mount anything that weighs more than a couple of pounds, it’s best to anchor it into a wall stud. Wall studs are the vertical framing lumber behind the drywall or plaster. Experienced carpenters simply knock on the wall and listen for the noise to go from hollow to firm. For everyone else, a stud finder is the tool of choice. Stud finders locate these hidden studs without drilling any unnecessary holes.
What is a stud finder?
“A stud finder is a handheld device used to locate wall studs and floor joists. A stud is a vertical beam that extends from the top to bottom of a wall that offers support and structure,” says Alanna Yee, Director of Global Communication Strategies at Zircon. “You’ll want to find a stud to secure heavy objects into the stud center, to install a window, door or electric box next to it or to avoid cutting into it. Not securing or anchoring objects to the stud can result in broken and ripped walls or falling objects,” she notes.
How does a stud finder work?
Yee says that a typical electronic stud finder works by sensing density changes. They determine the edge, center and direction of a stud as well as detect other objects behind the wall. However, electronic versions aren’t the only type of stud finder. There are also magnetic versions, which are less expensive by typically have fewer capabilities.
Consider these factors when choosing the best stud finder for you:
- Electronic or magnetic: Electronic stud finders use sensors to detect a change in density behind the wall and send an alert—usually an LED or audible beep—to indicate a stud. Magnetic stud finders use powerful magnets to detect the metal nails used to fasten the wall to the studs. Magnetic stud finders can be more challenging because they must locate the metal in the stud, but they don’t require any batteries so they’re always ready for use.
- Type of display: Electronic stud finders have a range of display options. Basic, inexpensive models use a single LED to show when a stud has been located. Others feature a large LCD screen to show exactly what exists behind the wall and where you should drill. Magnetic options offer display variations. Some simply stick to the wall when a stud is located, while others use a colored ball to “pop” up when it detects a stud.
- Cost: If you’re a DIYer with little experience locating and mounting things on studs, consider a higher-end electronic stud finder that does all the work for you. It can be tempting to save money on a cheaper tool, but if you’re not sure what you’re doing, you can end up damaging your wall and spending more money to patch it up. If you’re comfortable with stud finders, a simple, inexpensive magnetic stud finder is just fine for most experienced DIYers.
- Wall material: While most people deal with drywall, older homes may have plaster-and-lath walls. In our experience, magnetic stud finders are more effective on plaster-and-lath, because the line of nails that secure the lathe to the stud runs all the way up the wall.
- Sensors: The number of sensors can vary by model and brand. “More does not equate to better,” says Yee. “The accuracy in which the tool detects its intended target is the most important.”

The two-in-one line laser and stud sensor detects metal, live wires and studs while simultaneously offering a bright level line to ensure pictures and other wall hangings look and perform their best. At over $50 it’s a bit pricey, but considering it’s a two-in-one tool, we give it a pass.

What to Look For When Buying Stud Finders
Finding the type of stud finder is just as important as locating the correct model. It’s also important to consider the project. “Stud finders typically are not recommended for use on lath and plaster because of the inconsistent way the lath is applied and its varying density,” warns Yee. “The use of wire mesh and metallic surfaces can also interfere with the tool’s sensor capabilities. Dense surfaces like concrete, brick and some tiles are not recommended. Stud finders are designed and recommended for interior use only.”
For big projects, an electronic stud finder may be the right choice. “Electronic stud finders sense density changes and manufacture a wide range of models that can find the center, edge and direction of studs, as well as metal and live electricity,” says Yee.
This is especially important to consider when working around electricity lines and plumbing. “Magnetic stud finders can be less expensive but are limited to detecting the nails or screws attaching the drywall to studs and cannot discern other items the way electronic stud finders can. To find studs, magnets can be inaccurate because the nails and screws could be placed at the edge of the stud and can also detect other metals.”
In addition to electronic vs. magnetic stud finders, there are different types of screens to consider. “LED versions use light indicators to designate a mode or indication while LCD screens display images or text onscreen. Functionally, LEDs can work well for their simplicity,” says Yee. “Stud finders can range from $14 for a basic model to $100 for multifunctional models with exclusive features.”

Looking at the cost, quality and reviews, it quickly became our best overall winner.
FAQs
Do stud finders scratch walls?
While safe to use, stud finders may scratch or damage walls, so always operate them with care. Yee mentions that some stud finders use velcro or gliding pads that make for smoother scanning and do not damage walls. For delicate surfaces or specialized paint jobs, this type is your best bet.
What’s the difference between a center finder and an edge finder?
Stud finders will either be a center finder or edge finder model. An edge finder only finds the edges of studs in your wall, so you’ll need to determine the center. A center finder displays the center and edges of the studs. Center finders tend to be more expensive, but for many it’s worth the price to get more detailed information about what’s behind your walls.
How far apart are studs in a wall?
Studs are typically 16 inches apart. The distance can vary in older homes, but it’s rare that your studs would ever be more than 24 inches apart. To find the distance in your home, use your stud finder on a large wall and measure the distance between each stud.
Can a stud finder be wrong?
It’s fairly common for stud finders to go off when they detect a pipe or other object that isn’t a stud behind your wall. You’ll see less of this in higher-end models, but it’s always best to double-check the work of your stud finder by locating three or more studs in your wall. If they are equidistant apart, you know that you’ve found studs and not something else and can continue with your project.
