Are you looking to hang something on the wall but need to know where the studs are? How to find metal studs in your walls can be a bit trickier than finding wooden studs, but it’s not impossible.

When embarking on a building or renovation project, locating metal studs within walls is a crucial step for effective planning and execution. Unlike their wooden counterparts, metal studs are commonly used in commercial construction due to their durability and resistance to fire, rot, and pests. However, identifying their exact location can pose a challenge because they are concealed behind drywall.

This guide will offer you the practical methods and tools needed to detect metal studs accurately. This will ensure that you can confidently hang heavy items or undertake other construction tasks without the risk of error. Adopting these techniques will streamline your construction process and avoid potential setbacks.

What Will You Need?

Before discussing how to find metal studs, gathering the necessary tools is essential. These include:

• A stud finder
• Magnetic compass
• Strong neodymium magnets
• Tape measure

Once you have these tools, you’re ready to search for metal studs.

10 Easy Steps on How to Find Metal Studs

Step 1. Use a Stud Finder:

A stud finder is an essential tool for detecting studs in the wall, and many modern stud finders are equipped to locate metal and wooden studs. Begin by turning on the stud finder and selecting the metal setting, if applicable. Place it flat against the wall where you believe a stud may be. Glide the device slowly along the wall, keeping it steady to prevent false readings. Stud finders usually indicate the presence of a stud with a series of lights, beeps, or digital readings. When you identify the edge of a stud,

mark it lightly on the wall with a pencil. Continue across the wall to find both sides of the metal stud, making marks each time the stud finder signals. This method ensures you can accurately gauge the center of the stud, which is vital for proper support when hanging objects.

Step 2. Use a Magnetic Compass: 

If a stud finder is unavailable or you’re seeking an alternative method, a magnetic compass can be a suitable substitute. Metal studs can slightly alter a compass needle’s direction due to their magnetic properties. To employ this method, hold the compass flat against the wall and slowly move it along the surface. Watch closely for any deviations in the needle, which could indicate the presence of metal behind the drywall. While this method may not provide pinpoint accuracy, it can help identify the general vicinity of a metal stud, allowing you to search more effectively with other tools.

Step 3. Use Strong Neodymium Magnets: 

Neodymium magnets, known for their strength, can be highly effective in locating metal studs. Slide the magnet slowly across the wall, and pay attention to any areas where it sticks. These magnets are drawn to the screws or nails that hold the drywall to the metal stud, providing a clear indication of a stud’s presence. Once the magnet attaches, mark the spot with a pencil. Move horizontally and vertically across the wall to pinpoint multiple attachment points, helping map out the metal stud’s line. This non-invasive method can be a fun way for kids to get involved in the home improvement process!

Step 4. Use a Tape Measure: 

Using a tape measure can also assist in locating metal studs, especially if you’ve already identified one. Typically, metal studs are spaced 16 or 24 inches apart from each other, center to center. Once you’ve found a starting stud using a previous method, measure 16 or 24 inches from that point and check for another stud using your stud finder, compass, or magnet. Repeat this process to map out the entire wall. This method relies on the standard spacing regulations in construction, providing a logical way to predict stud placement throughout a wall.

Step 5. Knock and Listen: 

Though a more traditional approach, knocking on the wall can offer clues about the presence of metal studs. Begin by knocking gently on the wall in a horizontal line where you suspect studs may be located. A solid, less hollow sound might indicate the presence of a stud behind the drywall. In contrast, the areas between studs often produce a more echo-like or hollow sound.

Use this method with other techniques like the stud finder or magnets to confirm your findings. It’s important to remember that while this method can be helpful, its accuracy is not as reliable as tools explicitly designed for stud detection. Nevertheless, this tried-and-true technique can serve as a quick and easy initial assessment before proceeding with further investigation.

Step 6. Look for Outlets and Light Switches: 

Electrical outlets and light switches are typically mounted on the side of metal studs, offering a useful clue for locating them. Because these fixtures need stable support, their placement on studs is quite common. Carefully observe the position of outlets and switches, then measure from the edge of the fixture outwards,

either 16 or 24 inches, to predict the center of nearby studs. Although this method could be more flawless due to possible installation variations, it provides a practical starting point for identifying adjacent stud locations. Use this approach alongside tools like stud finders or magnets for increased accuracy.

Step 7. Use a Flashlight and Look for Wall Indentations:

Shining a flashlight parallel to the wall’s surface can help reveal subtle indentations or imperfections that signal the presence of a stud behind the drywall. These indentations often occur where the drywall is attached to the stud with screws or nails. Hold the flashlight close to the wall and move it along horizontally. Look for any slight dimples or shadow variances that may indicate a screw or nail, betraying the location of a metal stud. While this method requires a discerning eye and good lighting conditions, it can provide visual cues to complement other techniques you’re using.

Step 8. Use a Metal Detector: 

A metal detector, typically used for finding buried objects, can be an effective tool for locating metal studs in walls. These devices detect the electromagnetic field emitted by metal objects, making them suitable for locating metal studs. To use a metal detector, sweep it slowly across the wall surface while keeping it steady and close to the wall. When the sensor signals the presence of metal, mark that spot. It’s an excellent way to double-check findings from previous methods and is especially useful in areas where stud finders might give inconsistent results.

Step 9. Check Ceiling and Floor Connections: 

In some buildings, especially those with metal frame construction, studs can often be traced by examining connections in the ceiling or baseboards. Studs are usually interconnected from floor to ceiling. By carefully inspecting the areas where walls meet floors and ceilings, you might notice screws or nails revealing stud positions. Once these are located, you can extrapolate the stud positions vertically along the wall. This method is another visual clue that, when combined with techniques like the flashlight or metal detector, can provide more comprehensive results.

Step 10. Consult Building Plans or Blueprints: 

When other methods are inconclusive, resorting to building plans or blueprints can provide precise information about stud placement. These documents detail the construction layout of the building, including the framework and spacing of metal studs. If you have access to blueprints, cross-reference them with findings from practical methods to ensure accuracy. Not only does this provide you with concrete data, but it can also save time and eliminate guesswork when searching for studs behind walls.

By following these tips and techniques, you can become proficient at locating metal studs in walls.

5 Things You Should Avoid

1. Using a Regular Stud Finder: Most stud finders are designed for wooden studs and may need to be more effective for locating metal studs. Ensure you are using a device specifically made for metal detection.
2. Relying Solely on Knocking: While knocking on the wall might help identify space between studs, metal studs can produce misleading sounds. Proper detection tools are best for accurate results.
3. Ignoring Wall Outlets and Fixtures: Wall outlets and light switches are often attached to studs. Failing to consider their placement can lead to inaccurate assumptions about stud locations.
4. Overlooking the Correct Tool Settings: When using a stud finder, ensure it’s set to the correct setting for metal detection. Incorrect settings can result in false readings.
5. Disregarding Building Plans: If available, review the building plans or blueprints. Ignoring these documents can lead to unnecessary hassle and inaccurate estimations of stud placement.

Avoiding these common mistakes can save time and ensure accurate results when locating metal studs.

Conclusion

To locate metal studs successfully, it’s essential to combine various methods for the most reliable outcome. Start by using an appropriate stud finder designed specifically for metal detection, ensuring the device is calibrated correctly.
