The best stud finder can make the difference between a successful and a disastrous DIY house project. When pounding or screwing objects into walls, ceilings, and floors, you need to know what's on the other side. After all, you don't want your large television to fall over because it isn't properly secured to a stud.

The best stud finders are useful to find studs that aren't visible. Knowing where they are is important so you can screw into them instead of the walls when hanging pictures, paintings, mirrors or flat-screen TV mounts.

Precision detection, rapid calibration, and an alert system are all features of the best stud finder. Many stud finders do the same thing. They detect support regions such as studs and joists. All stud finders detect wood, metal for the majority, and active electrical wire for many.

Other stud finders only have rudimentary detection capabilities and are only useful for detecting wall studs. Others can be applied to the walls, floors, and ceilings. Finally, the best stud finders allow you to vary the depth to which the sensors penetrate the wall. Thus, they increase your chances of finding studs and everything that matters.

What Types of Stud Finders are Available?

1. Electronic Stud Finders

Electronic stud finders detect minute changes in the electric field within the wall. The devices can read the density of the wall using these scans. There's a stud if the density reading is high. There is nothing but space if it is low. Advanced settings on specific models allow you to scan for other things in the wall, such as copper piping and wires.

2. Magnetic Stud Finders

Magnetic stud finders work in a more indirect manner. Magnetic finders employ magnets to identify the nails or screws that hold the drywall to the studs rather than sensing the stud itself. A magnetic finder hangs on the wall in the exact location of drywall screws. It allows you to mark it with a pencil without having to use your hands.

This type of metal detector should be used with caution, especially if you are drilling or cutting into the wall. This type of sensor can sometimes misread a pipe or other metal objects inside the wall as a stud. This method requires that the drywall be screwed down in the exact middle of the studs by the constructor. That isn't always the case!

3. Smartphone Stud Finders

There's a third form of stud finder that you're probably already familiar with! Most cellphones feature built-in magnetometers, allowing them to be used as magnetic stud finders. In addition, there are numerous free stud finder apps available for both Apple and Android. Unfortunately, they have the same issues as any magnetic stud detector and are significantly less accurate than electronic stud finders.

Which Type of Stud Finder Should I Buy?

Because there are no electrical parts or batteries to replace, a magnetic detector is less expensive or free if you use a smartphone app. It has a smaller likelihood of breaking. A basic electronic stud finder, on the other hand, is the way to go for the average homeowner. One can cost around $25 and is far more accurate than the magnetic type.

If you settle on an electronic finder, one thing to look for is its depth capacity. It may have a switch that allows you to choose between standard drywall depth and a deep scan of up to 1 1/2" for locating studs through a firewall or two layers of drywall. We have compiled the best stud finders on Amazon for this review to help you find the best stud finder for your home.

How to Choose the Best Stud Finder

1. Number of Sensors

Electronic stud finders have advanced significantly since their introduction to the construction market in the 1990s. An electronic stud finder employs sensors to detect a mass behind the wall to determine the placement of a stud.

They may have a single sensor, allowing them to detect simply the edge of a stud. However, several sensors allow them to detect both the edges and the center of the stud. Stud finders with a single sensor and many sensors both work well on average.

2. Sensor Size

Sensors come in a variety of sizes. Stud finders with larger sensors provide the ability to cover a greater area and penetrate more substantial or thicker walls, such as plaster or concrete.

Smaller sensors have the potential to be extremely accurate. Sensor size isn't an issue for most house DIYers. A standard stud finder with smaller or larger sensors will be able to locate studs under the drywall.

3. Built-in Bubble Level

Built-in bubble levels can be found on either an electronic or a magnetic stud finder. It helps you level shelves or whatever else you're mounting on the wall. However, it only records levels over a relatively limited distance. As a result, small bubble levels are less precise than longer, carpenter-type levels.

4. Built-in Laser Level

A built-in laser is only available on electronic finders. A laser level is an upgrade from a bubble level. You may shine a laser in a straight line from the stud you've located, either vertically or horizontally.

At the touch of a button, the laser level will assist you in aligning additional fasteners. Hanging a picture frame or painting on a wall at the same height is a breeze with a laser level.

5. Depth Adjustment 

With depth adjustment, you can go from detecting studs 3/4-inch deep behind drywall to locating any number of objects up to 1-1/2 inches beneath the surface. It is available on electronic models only. Increasing the depth adjustment consumes more energy and depletes the batteries faster.

6. Multipurpose

Electronic "multipurpose" stud finders work by detecting extra elements within the walls. For example, they detect live wires and plastic pipes, so you don't nail or cut into something dangerous.

7. Visual Display

Various visual displays are only available on electronic models. They allow you the option of how you want to see the stud. Some electronic stud finders include an LED screen that displays a digital map of the stud beneath the wall.

Others have LED lights across the top that flash when the finder is passed over a stud. They provide a dependable means to locate a stud.

8. Battery Indicator

A battery indicator will alert you on some electrical models when it's time to replace the batteries. Some electronic models work with AAA or two AA batteries. Others require the use of a small 9-volt battery to power several functions.

Frequently Asked Questions(FAQs)

1. How Do I Use an Electric Stud Finder?

When the stud finder is off, hold it to the wall. You could believe that you need to hit the button before starting, but when you switch it on, the unit calibrates to the wall. Simply attach the gadget to the test wall and switch it on with the button on the side.

If you start your scan on a stud, an error warning will appear. Simply turn it off, move it a few inches to the side, and try again. Move the stud finder in a linear line until it beeps. Once the screen has turned on and been calibrated, slowly slide the stud finder in one direction while keeping the button pressed.

When a stud is identified, it will beep and display an image on the screen. A series of escalating bars are displayed on the screen. The more bars emerge, the closer you are to the stud. The display will fill in once you reach the stud's edge.

Keep in mind that most stud finders only display the stud's perimeter, not the center. Therefore, it is critical that you locate the stud's center. To find the center of the stud, mark the edges of the stud.

First, mark the stud's edge point on the wall with a pencil, then slide the stud finder to the opposite side of the stud. Then, repeat the procedure in the other direction. You've found the other edge of the stud when the stud finder beeps again.

Between those two spots is the center. A stud is typically 1 1/2" wide. Thus, the center will be 3/4". If you don't want to write on your walls, attach a strip of painter's tape to the wall and make your marks there.

Depending on the sort of building you're working on, studs must be 16 or 24 inches apart, according to the building code. Mark the centers of two studs after you've located them, and then measure the distance between them.

You now know the exact distance between each stud in the structure. Simply pick a stud and measure in either direction to discover the additional studs in the wall for the rest of your project.

Builders may set unusual stud locations or use irregular spacing on a short wall. Although this method provides a decent estimate of where the stud should be, you should always double-check using the stud finder.

2. Are Outlets Always Mounted on Studs?

The majority, but not all. Some outlets include boxes that are meant to fit into a hole in the drywall. If this type of outlet box is used, the best stud finder that detects both studs and live wires can alert the user.

3. How Widely Apart are Studs?

The average distance between studs is 16–24 inches, but this isn't always the case. Measure the wall for all studs before hanging picture frames or other objects that require more than one stud.
