Learn how to confidently locate studs in your walls using a variety of techniques and tools, from simple methods like tapping on the wall to more advanced options like stud-finding apps and inspection cameras. This comprehensive guide is designed for beginner and experienced DIYers alike.


If you’re a DIYer who wants to hang a heavy mirror, a television, or some shelves, one of the most important things you need to know is how to find studs in your walls. Studs are the vertical framing members that support your walls and hold up heavy objects. Without them, your wall hanging could come crashing down! In this article, we’ll explore several methods for locating studs, from the super simple to the more advanced. No matter your skill level, we promise you’ll be able to find studs with confidence after reading this guide.

5 Simple Methods for Locating Studs in Your Walls:

Let’s start with some easy methods that don’t require any special tools.

Method 1: Measuring from an outlet or switch

In most homes, electrical outlets and light switches are attached to studs. So, you can measure horizontally from an outlet or switch to find studs along the same wall. In general, studs are spaced either 16 or 24 inches apart, center to center. Use a tape measure or ruler to make your measurements. This method works best when the outlet or switch is installed properly and centered on the stud.

Method 2: Tapping the wall to listen for changes in sound

Studs sound different than hollow wall cavities when you tap on them. To use this method, start by tapping lightly on the wall with your knuckles. You should hear a hollow sound. Move your hand over a few inches and tap again. You should hear a solid sound. That’s the stud! This method works better on walls with wood paneling or older plaster and lath walls.

Method 3: Spotting clues on the wall (e.g. nailheads, paint lines)

Over time, wall coverings and paint may reveal where studs are located. Look for small bumps or dots in the paint that might indicate a nail or screw head below. You may also see visible lines where paint or wallpaper has been applied over a stud seam. While these clues aren’t always reliable, they can be helpful in combination with other methods.

Method 4: Using a flashlight to look for changes in surface texture

If you shine a flashlight across the wall at a low angle, you may be able to detect subtle differences in surface texture where studs are located. The light will cast shadows across the surface that can make the texture changes more visible.

Method 5: Checking the baseboard or crown molding for nails or screws

In many homes, baseboards and crown moldings are nailed or screwed into studs. Use a pry bar or putty knife to gently remove a small section of molding or baseboard and look for nail or screw holes. You may even be able to detect the location of studs by the spacing of the holes.

DIY Guide: How to Find Studs Without a Stud Finder:

Stud finders are handy tools, but they aren’t always necessary or accurate. Here are a few DIY methods you can try instead.

Method 1: Using a strong magnet to detect metal screws or nails

Slide a strong magnet over the wall surface, and pay attention to where it sticks. It will likely be attracted to metal fasteners, which are often used to attach drywall to studs. If you find a fastener, move the magnet in a circular motion to determine the width of the stud. This method isn’t foolproof, but it’s another simple test to try.

Method 2: Using a thin wire or coat hanger to poke through the drywall and feel for resistance

You can use a piece of wire or a coat hanger to poke through the drywall and feel for resistance. When you hit a stud, you’ll feel more resistance than when you’re only poking through the drywall. Use a marker to make a small dot where you feel the resistance. Be careful not to poke too hard or make a hole in the wall!

Method 3: Using a piece of hardwood or metal to tap the wall and locate studs by sound

Similar to tapping the wall with your hand, you can use a piece of hardwood or metal to tap on the wall. Look for areas where the sound is solid rather than hollow. This method may take some practice to distinguish between sounds, but it can be an effective way to locate studs.

7 Foolproof Ways to Find Studs Every Time:

If you’re serious about DIY home improvement projects, you may want to invest in a dedicated stud-finding tool. Here are some of the best options available.

Method 1: Using a specialized stud-finding tool (explain different types)

Stud finders come in several forms, including magnetic, electronic, and ultrasonic. Each type operates differently but is designed to locate studs behind drywall quickly. Magnetic stud finders detect metal fasteners, while electronic and ultrasonic models use sensors to determine the density of the wall material and locate the stud accordingly. Some models feature LEDs or audible alerts to indicate stud locations.

Method 2: Measuring from a corner or doorway

Studs are usually positioned around doorways, windows, and corners. You can use a tape measure or ruler to measure 16 or 24 inches on either side of a doorway or corner to locate the studs. This works best when the room is laid out evenly.

Method 3: Using a laser level or plumb line

You can use a laser level or plumb line to create a straight vertical line on the wall. When the line intersects with a stud, you’ll know where it’s located. The downside to this method is that you need a clear path between two walls so that you can create the line.

Method 4: Drilling a small test hole to confirm the presence and location of a stud

If you’re not concerned about making small holes in your walls, you can drill a small test hole to determine whether a stud is behind the wall. Drill a hole slightly larger than the diameter of a coat hanger wire. Use a flashlight to look inside the hole and see if you can spot the edge of a stud. If you do, mark the spot and fill the hole with spackle.

Method 5: Using a borescope or inspection camera to see inside the wall

A borescope or inspection camera is a flexible tube with a camera on the end that you can snake into small spaces. You can snake the borescope through a small hole to see inside the wall and locate the stud. This method may not be practical if you don’t own a borescope.

Method 6: Using a stud-finding app on your smartphone

There are several stud-finding apps available for smartphones. These apps use the phone’s internal sensors to detect metal or changes in wall density and can help you find studs in your walls. Not all apps are created equal, so be sure to read reviews before you download.

Method 7: Consulting a blueprint or building plan to locate studs in advance

If you’re building a new home or gutting an existing one, you can consult a blueprint or building plan to locate studs in advance. Building plans typically specify the location of studs, and knowing this information can save you time when you’re hanging wall hangings or shelving later on.
