What Is a Stud Finder?

stud finder

Stud finders are handheld tools that you can use to detect framing studs that exist behind the surface of your house walls. These devices measure the electrostatic field that’s generated by a wall and determine small differences that occur in the electrons’ flow. In other words, stud finders show you the ideal spot to insert a nail by discovering relative changes in the wall’s density.

Some of these tools rely on magnetic fields to either scan the wires or find nail heads that are located in the studs. On one hand, you can hang photos or shelves on your walls anywhere you want without using a stud finder. On the other hand, if you don’t use a stud finder, those objects could come crashing down because there’s the risk of placing them on sheetrock.

How to Find the Best Stud Finders – Buying Tips

If you want to find the best stud finder that matches your needs and budget, there are certain things you should consider. First of all, decide what type of stud finder you want to purchase. Secondly, characteristics such as materials, design, ergonomics, and precision are also very important.

Stud finders aren’t normally expensive tools. Some people even consider this purchasing decision a lot easier than the one buying a new table saw. Nevertheless, you still need to find the right tool that’s worth both your time and money.

Things to Look for When Searching for the Perfect Stud Finder

Stud Material

The majority of homes are made with wooden studs. At the same time, commercial buildings are different because their structure might contain metal studs. In some cases, even plastic studs are used. Some stud finder models have a simple caliber that’s focused on finding one single type of studs.

Therefore, before buying a stud finder, do your homework and discover what types of studs your walls are made of.

Stud Location

Where are you searching for studs? Do you want to locate them in your house’s walls, floors, or ceiling? You need to know these details because stud finders that come with basic features might not be powerful enough to locate studs through thicker floors.

Another thing that’s linked to the location of the studs is the tool’s grip which must be good. A comfortable grip enables you to operate the device regardless of the angle.

Additional Features

Some people just want to buy a straightforward handheld machine that doesn’t do anything besides finding studs and that’s perfectly fine. Still, certain high-end tool models provide additional features that are extremely valuable because they will help you if you’re involved in more complex projects.

For example, some stud finder units are created to detect live wires as well. Others can register a virtual map of the wall or the surface you’re examining.


Although many stud finder models are pretty affordable, the best models that come with the most valuable features are quite expensive. A basic stud finder can cost as low as $20 while a top-notch model can have a price tag of $100 per unit.

Before establishing a final budget, think about how often you intend to use the device and the projects you are going to use it for. If you plan to complete numerous home improvement projects, you may want to opt for a better model that’s also more expensive.

Usually, electronic stud finders cost more than their magnetic counterparts.

Sensor Size

Besides the sensor type which can be electric or magnetic, there’s also its size that you must keep in mind. A bigger sensor might provide more advantages compared to a smaller sensor. A tool that features a wide sensor area will definitely cover a larger surface in less time. Some models can even detect multiple studs at the same time.

Visual Display

virtual display

This is a feature that you will find only on electronic stud finders. Magnetic models don’t have and don’t need one because they are built to stop in whichever place they encounter a stud. There are many versions of visual displays so it all comes down to the things you want to see.

Simpler electronic stud detectors have LED lights that start to blink when they come across studs while more complex alternatives also show the distance from the tool to the stud.

Design and Grip

The best stud finders are those that make it easy for you to hold and handle the tool. The grip must be strong yet comfortable because you will have to move the device across the wall or another surface while also performing smooth and continuous motions. If the design is bulky and it lacks ergonomic structure, you won’t be able to hold it properly and the reading will be less accurate.

Alert Systems

There are two main categories of stud finders and each of those types comes with its own alert system which relies on the sensor type. Electric stud finders offer a visual cue through a display screen every time they detect a stud. Magnetic stud finders don’t normally have additional alert systems.

To make sure you accurately locate where studs are, you should find tool models that feature audible warning noises or beeps. Certain devices have extra light displays that you can see reflected on the wall, right above the scanner.

Types of Stud Finders

There are many stud finder options out there but most of them can be included in the following two categories:

  • Magnetic stud finders;
  • Electric stud detectors.

Electronic Stud Detectors

Most people prefer to buy electronic stud finders rather than purchasing magnetic ones because they are easy to handle and have plenty of useful visual display options. Also, they seem to be a tad more accurate compared to magnetic tools.

Using an electronic device is quite intuitive due to the fact that there are only a couple of buttons you will have to manage to complete the job. Having a few buttons will maintain confusion at a minimum. On the other hand, the majority of electronic stud finders are powered by batteries. This can be pretty inconvenient because you must always verify the tool to see if the batteries are charged before starting a project.

The main advantage of this type of stud locator is the abundance of details you receive just by looking at a screen that will help you detect the exact place in which a stud can be found.

Magnetic Stud Finders

This is a common type of stud finder and many people use it due to its simplicity and straightforward design. It is also more affordable than its electronic alternative. These devices function with magnetic sensors that locate studs in your walls. They are highly accurate.

You don’t have to be an expert to use a magnetic stud finder because it isn’t complicated at all. This version of a stud detector is elegant in its simplicity. You won’t have to decipher any complex data on a screen. Moreover, these tools don’t need batteries to function. This is certainly a huge advantage because it means that you will be able to use the device for a really long time.

Another great perk of magnetic stud finders is their high level of portability. Although many stud locators aren’t very large, magnetic ones are easy to carry around. They fit inside many toolboxes or even storage chests where you can keep them for easy access.

Whole Stud Detectors

It’s true that the most common types of stud finders are magnetic and electronic ones. However, there’s also the whole stud detector which is a very interesting model because it has a different operation method.

While the other devices determined a stud’s edges and then locate its center, a whole stud finder discovers the entire stud. So, you can understand the stud’s full depth and find out more information about it.

These types of stud finders are mostly used by construction workers and building service professionals but you can easily use them for your home projects. You’ll need both hands to maneuver this tool around a surface.

One of the most convenient features that a whole stud detector comes with is an auto-depth scan which enables users to find out how thick drywall is. When you get hold of this information, you will know exactly what to expect.

Styles of Stud Finders

In terms of styles, there are five different available stud finders that you should know about before making a purchasing decision.

Stationary Magnetic Stud Detectors

These devices function with a stationary magnet to locate where studs are inside a wall. The magnet will quickly determine the exact location of screws and nails within a surface. All you have to do is move the tool around the wall until you feel its magnetic power pulling in. This item is less accurate than other categories of stud finders.

These products are very affordable but, if the stud was placed too deeply into a surface, it will be very hard for you to detect its exact location with a stationary magnetic device.

Moving Magnetic Stud Locators

Another sub-category of the magnetic stud finder group is the moving magnetic alternative. Instead of using a stationary magnet, this product features one that’s moving. This helps you find the stud a lot quicker and more accurately. It is also more powerful than the previous version and it can locate even those studs that are deep inside the wall.

As soon as it locates a stud, the magnet will start moving while also making an audible noise. It is a highly effective gadget and many professionals like to use it due to its reliability.

Electronic Edge Finders

These are the most frequently-met types of electronic stud detectors. They work great when you want to drill into the wall for a TV mount or hang up a framed photo or a painting. Just like the name suggests, these devices locate the edges of studs so that you know the proper place to hammer or drill in order to reach the stud.

As a possible downside, this tool won’t tell you where the stud’s center is. Therefore, you will have to establish or estimate that on your own.

Electronic Center Finders

These gadgets will accurately detect where the stud’s center is within your wall. They rely on two sensors to complete a proper reading of a certain surface. You must keep moving the tool over a wall until both sensors show the same information. This product works on batteries and it is marketed at a reasonable price.

Instant Stud Finders

This type of stud locator was recently launched on the market and, when it was first presented to the public, it was considered pretty innovative. It functions with a multitude of different sensors that work together to locate studs behind any wall. The best part about this option is that users aren’t required to move the product around the wall.

It is very easy to use but there’s a drawback: its price which is higher compared to one of the other similar stud detectors.

Radar Stud Finders

These are the newest models of stud locators and they use radar technology. These tools release radio energy pulses that bounce right back to the stud finder as soon as they reach items such as nails, electric wires, wood, and pipes. All these elements reflect those radio waves.

Although these stud locator models are very effective, they are also more expensive than previous versions like magnetic or electronic ones.

Speaking of wall finders, here are also the Best Drywall Sanders you might need in case you do wall work soon.

The Most Important Features to Look for in a Stud Finder

There are many features that you must consider when buying an efficient stud finder. Let’s detail some of the most important characteristics.

Automatic Shut-Off Function

This particular feature will help the tool last longer because it prolongs the life of the batteries. Some stud detector models have an energy-saving option and if you purchase an electronic model, you might even enjoy its automatic shut-off trait.

Auto-Depth Detection

This feature enables users to establish the drywall’s thickness, providing them with plenty of useful information to work with. This will further lead to a more effective plan and a better result. These types of stud finders are very convenient because many of them are sold at reasonable prices.

LED Display

LED displays are another convenient feature that a good stud finder has. This characteristic shows both the center and the edges of any stud it may encounter. Therefore, you will receive accurate information regarding the things you find under a surface.

Multi-Mode Detection

This feature allows you to find out exactly the type of studs you’re dealing with, whether they are made of metal, wood, or plastic. Also, it can determine a stud’s depth and detect any AC wire that could be present.

Two-Way Level

To make the work even easier for you, some stud locators will feature two levels to help you mark the exact spot of a stud. It is highly convenient and comes in handy all the time, regardless of the type of stud you’re trying to find or the type of project you’re initiating.

Hands-Free Use

This is a characteristic that can be found in magnetic studs. Some products have so powerful magnets that they enable hands-free use. These devices attach themselves to a wall due to their strong magnetic force. It allows you to let go of the tool and mark off the place where you find the studs.

How to Properly Use Stud Finders – Main Tips

Here are some easy-to-follow guidelines on how to correctly use these tools to locate studs in your walls:

  • While the stud finder is in use, avoid touching the wall with your hands because it can alter the reading;
  • You may have to calibrate the tool before starting the scan which is why it is best to begin the search away from things like outlets, switches, and light fixtures;
  • Applying a layer of painter’s tape right over the surface you want to scan is good because you can then mark the locations of the studs on it without writing directly on the wall;
  • Once the device locates a stud, scan around it to make sure the item continues up and down the wall to either the ceiling or the floor. These could be plumbing or wiring;
  • If your wall is freshly painted, you might want to wait a couple of weeks before scanning. Errors might occur because of the wall’s paint moisture.
