Studs are boards that function as framing elements in a buildings wall, supporting the walls. They are vertical repetitive framing members in a wall of smaller cross-section than a post. Studs are usually made of wood and are spaced equally to suit the dimensions of the covering sheet materials, usually 16 or 24 inches on center (measured from center to center) along the wall and run between the floor and ceiling. Drywall or lath (for plaster walls) attaches to the edge of the studs. Studs hold in place the windows, doors, interior finish, exterior sheathing or siding, insulation, and utilities and help give shape to a building. Many fasteners and hangers used to hang heavy objects, such as large pictures, mirrors, shelves, and television mounting systems, need to be anchored in studs because the wall alone isn’t strong enough to support the weight. Studs provide the best support for the fasteners, and the center of a stud provides the best support for the fasteners. To find studs in a wall, one can use an electronic stud finder or try to find them manually.
