Studs are vertical wood members in {{w|Framing_(construction)|wood-framed construction}} common in North America, although steel framing has become a popular alternative. These supports reinforce a wall at regular intervals, typically 16 inches (about 40 cm), and at corners, windows, and doors. | Studs are vertical wood members in {{w|Framing_(construction)|wood-framed construction}} common in North America, although steel framing has become a popular alternative.

| β | Most stud finders use an electrostatic field that is affected by the densities and types of materials in the vicinity, identifying where studs and other significant framing elements are located. One might want to know the locations of studs within a wall for installing wiring, mounting shelves and heavy objects to walls, or in this comic, hanging a picture. Wiring can be inserted between studs behind the {{w|drywall}}, while shelves, pictures, etc. are better affixed to studs | + | Most stud finders use an electrostatic field that is affected by the densities and types of materials in the vicinity, identifying where studs and other significant framing elements are located.

Many stud finders have a light that turns on in conjunction with a beep when a higher density is detected, indicating the edge of a stud. But there are circumstances that can fool stud finders. Most are designed for the drywall-over-wood-framing construction, and can be fooled by older {{w|Lath_and_plaster|plaster and lath}} construction where the density is much more uniform throughout the length of the wall. Lower quality stud finders can also be fooled by things like moisture in the drywall or wiring within the wall cavity, and may thus beep when there is not a stud behind the scanned location. As a result, many people will try alternatives such as using a magnet to find the drywall screws or nails, or tapping a finishing nail through the wall to see if there is a stud underneath. | Many stud finders have a light that turns on in conjunction with a beep when a higher density is detected, indicating the edge of a stud.
