Studs are wooden or metal beams behind your drywall that form the framing. When you’re hanging heavy items, like wall-mounted TVs, shelves, or artwork, drilling into a stud will give the item the support it needs.
To find studs, you can use a stud finder. A stud finder works via a magnet or electronic sensor, signaling when a stud is behind the wall.
Types of Stud Finders
Stud finders vary in price, ranging from less than $10 for a simple magnetic model to hundreds of dollars for professional models. The best stud finders for frequent DIYers cost around $50, but cheaper options are available.
The three main types of stud finders include:
- Magnetic – Magnetic stud finders are attracted to metal, so they cling to the wall when near a drywall fastener. In most cases, stud spacing is every 16 inches, and drywall screw spacing is 8-16 inches along a stud. If the magnetic stud finder clings to the wall in a pattern imitating drywall screws, you’ve likely found a stud.
- Electronic – Electronic stud finders scan the density in the wall and beep when the density changes, locating the studs. Some stud finders find the center of studs, while others locate the edges. It’s important to know which kind you have.
- Multi-purpose – Multi Purpose stud finders have multiple capabilities which vary by model. Some features include locating studs, metal, and AC wires.
