Whenever you want to hang something on a wall with a screw or nail, there is always a chance that the object is going to be little heavy like a picture frame or shelf system. The weight of these objects can be more than the fastener was made to handle. Eventually, the wall will give up and the project will be lying on the floor. The only way to avoid such mishaps is to find a solid and safe attachment point such as a wall stud.

But finding a wall stud can be a cumbersome work, it is complicated and hard to determine the exact location of the metal or Wood stud behind the tiles, drywall or any other surfaces. Surely you can keep on guessing and guess for eternity, and maybe if you are lucky, you might as well find the stud. But that will be very frustrating and tiring. Eventually, you will end up with a lot of wasted time along with some couple of holes that needs to be patched, filled and painted. But fortunately to spare you from all that hassle, we have stud finders.

Stud finder aka stud sensor or stud detector is a small handheld device that is used to detect framing studs that are situated behind the walling surface such as dry walls, plasters or other surfaces. They are very handy for different types of DIY jobs and one can carry it easily around the house. So, how to find the best stud finder? Where to buy from? What are its features? This Best Stud finder guide will help you learn everything you need to know.

When attaching or hanging anything on the wall, it is very important to keep in mind that the nail or screw is fastened into a framing member or a stud. Detecting a stud is a tiring job without using the right equipment. And as stud finders are available in different types, it important to know each of them. Which stud finder is good for what purpose should be known beforehand. While buying a stud finder, there are some features to look out for, but the final decision completely depends on your type of DIY work.

How to choose a right stud finder:

There are mainly two types of stud finders:


Magnetic stud finders sense the location of nails or screws holding the surface to the stud. When you find these metal fasteners, you’ll get to know the approximate location of studs behind the wall. For finding the stud, you need to slide the magnet slowly on the wall until you feel the slight magnetic pull of the screw or nail. Once you find the nail, these stud finders will make a sound of “click” or their rotating magnet will point towards the fastener.

The only drawback of this type of stud finders is that they cannot detect a screw or nail that is deeply located beneath the wall. This results in wastage of time during project installation. Also, it is important to note that the magnetic stud finders can only detect the location of metal fasteners. They cannot detect wood studs and door framing.

The second type is the electronic stud finder. They are far more efficient and advanced than the magnetic stud finders. For finding the wall studs and other metal fasteners above or beneath the wall, these stud finders make use of modern electronic sensors. The electronic stud finders require batteries for their working. They provide an audible or visual alarm upon finding the stud.

Further, Magnetic stud detectors have two different types

  • Stationary magnetic locators:

Stationary magnet stud locators have a small stationary magnet inside them for locating screws or nails placed in studs during doing the walling material.

In order to detect the stud, the user is required to move the magnet back and forth on the wall until he doesn’t feel a strong pull of magnetic attraction, while still continuing to move in the direction of attraction.

As stationary magnet stud locators highly depend on the user for feeling the attraction, it can be sometimes erratic especially if the metal fasteners like nails or screws are situated more deeply beneath the wall, thus, decreasing the overall magnetic attraction.

The biggest drawback of a stationary magnet comes into picture when the fasteners are situated very deep inside a thick wall like concrete or plaster wall. This thickness considerably lowers the effectiveness of stationary magnets.

  •  Moving magnet stud locators:

Moving magnet stud locators have a little complex working that consists of a small but powerful neodymium magnet.

This neodymium magnet is suspended in a closed enclosure wherein it is free to move in the direction of metallic pull. The moving magnet stud locator can work on a wide range of constructed surfaces. This becomes possible because of the easy movement and strength of the neodymium.

The moving magnet is initially suspended in such a unique way that it is always stable on its resting place until it detects the metal studs or metal fasteners.

On the surfaces that have shallow placed nails or screws, it’s magnet moves with a great velocity towards the wall, such that it actually makes a unique sound of “thud” when it touches the wall.

Nails or screws that are buried deeply under the surfaces such as in tile or plasters can be easily detected by this type of stud finder since its moving magnet is independent of the user to feel the magnetic pull off metal.

But the “thud” sound is little softer in deeper fasteners as the velocity of movement is little slower.

Internal Capacitor or electronic stud detector:

This is the second major type of stud detector that works by making use of a plate that can sense the changes in the electromagnetic composition of the surface.

The varied density indicates that the framing stud has been detected. Electronic Stud Finder is the most common type of stud detector used by the users and furthermore, it comes in 3 different types. These 3 three sub-types are edge finder, center finder, and instant stud finder.

  •     Edge finders – Edge finders are the most basic electronic stud detectors. They consist of internal capacitors. Edge detectors find the edges of a metal stud or other materials beneath the surface. In order to work with this type of stud finders, you must first calibrate it on an empty portion of the surface, and then it can be slid back and forth on the surface until it detects a density change, such as at the edge of any studs.

For drilling the hole accurately at the center of the edges, you must first find both the edges of the stud and for finding both the edges, you need to move the edge finder from both the directions on the surface. Some of the Edge finders having single sensor are error prone. They indicate the location an inch or two from the edge of studs. Once the edges of the stud are determined, the user must mark the center spot of the stud.

  •     Center finders – Center finders work more efficiently than the edge finders but that doesn’t mean you should forget the edge finders. The major performance of the stud finders depends on upon the manufacturer’s quality and not the technique. Well, coming back to the working of center stud detectors, the center detector detects the center of the stud with the help of using two separate sensors. These separate sensors register two different readings of the di-electric constant of the wall.

Once these two readings are matched, the center stud detector indicates that it is placed in the center of a stud. For determining the target center, several readings are taken into consideration. Unlike the edge finders that require being moved from both the direction on the surface, center stud finders require being moved from only one direction.

For proper working, Center stud finders also require calibration on an empty surface of the wall. If the calibration readings are not proper such as in a case of bumpy movement due to wall texturing, then the overall preciseness of the stud finder takes the toll.

  •     Instant Stud Finders or Scan Tools – This type of stud finders are the most advanced and accurate stud scanners. They can locate the metal or wood studs in concrete and dry walls consisting steel and copper pipes along with live wires. This type of stud scanner does not have the requirement to move them across the wall like other types of stud finders. They need to be simply placed on the wall.


Their multiple sensors detect the exact place of studs along with their thickness and the location of their center. Instant stud finders can also help us find the stud fewer areas just to avoid the support beam, in cases like installation of dryer vents or other electrical outlets.

How do stud finders work?

Well, the working is actually quite simple. Wood or other such materials are poor conductors of electricity. The poor conductors of electric current are also known as insulators. These types of insulators are excellent in supporting the electrostatic field. The electrostatic field produces an electrical or static energy which is then detected by the stud finders with the help of capacitor plate.

The detection of changes of electrostatic field gives the density difference between the dense wood (the stud) and dry wall. This, along with the clever circuitry of the scanner allows the stud finders to find the edge of the stud and the center of the stud with greater accuracy.

In the more advanced stud finders, the circuitry is so complex, that with a combination of a couple of different scanning methods, it can even detect the type of material depending on its density.

The more costly stud finders can locate the hidden electrical wires, metal pipes and nails/screws and can even scan 3-4 inch deep. This kind of advanced stud finders is called as a multi-purpose or multi-scanner stud finders.

They are not just used for finding the studs in the wall, but can also be used for finding the beams in the floor, ceiling, locating metal beneath the wall and other surfaces or even for locating metal fasteners beneath the tiles.

These stud finders as mentioned earlier, use a mixed working of density sensors, small scale radar, magnets and metal detecting hardware.

A combined use of all these scanning techniques allows the advanced stud finders to provide an accurate picture of what’s hidden beneath the wall or other such surfaces.

Also, while purchasing the right stud finders, the cost should be taken into consideration. You don’t want your DIY project to cost more than hiring a professional. The cost of stud finder changes depending upon the complexity of the machine, condition, and brand. A careful evaluation of your needs along with a proper research of price range and different available options should be done.

The brand of the product also plays an important role in buying quality stud finders. Some of the major brands are Zircon, Stanley, and Bosch. But again, the final decision depends on your personal needs and budget.

Another aspect to consider is to understand your purpose. Whether you want a basic metal stud finder or you want an advanced electronic Wood stud finders, whether you just want to locate the stud or you want any extra information about the center or its depth, it all solely depends on you.
