What Is The Distance Between Wall Studs?

Stud spacing varies depending on the height of the wall and what the wall is supporting. Spacing on the center is calculated from the center of the width of one stud to the center of the width of the next stud.

• Interior non-bearing wall

An interior non-bearing wall requires a minimum stud size of two inches by three inches that is spaced 24 inches maximum on center. This will apply to any interior wall that is not supporting the roof or the floor.

• Exterior wall supporting a roof

An exterior wall that only supports the roof of the house requires a minimum stud size of two inches by four inches that is spaced 16 inches maximum on center. This will apply to one-story home walls or the walls of a top floor in a two-story home.

• Walls that support a floor

A wall that supports a roof and one floor requires a minimum stud size of two inches by four inches that is spaced 16 inches maximum on center. This will apply to exterior or interior load bearing walls on a first floor of two-story homes.

• Walls that are more than ten feet tall

To prevent frame distortion or racking, a wall that is more than ten feet tall requires a stud size of two inches by six inches minimum. This will apply to any exterior or interior walls that are higher than ten feet. The stud spacing will remain at 24 inches minimum for an exterior wall that supports a roof and an interior non-bearing wall, and 16 inches for a wall that supports a roof and a floor.

As to structural regulations with regards distance between the studs, local energy codes will regulate insulation requirements that can alter the ideal depth of a wall. Larger studs could allow for stud spacing that is wider and for thicker insulation. This could result in sturdier walls and possible future savings with the energy costs.

Center to center 16 inches. Between the studs, approx. 14 1/2 inches.
