How to make and install shelves
Page 3: Find the studs
Determine the desired shelf position and then seek the possible fixing members. Although fixing uprights or shelf brackets through the wallboard into the wall studs is preferred, it is not always possible and in some instances the uprights or shelf brackets may have to be fixed to the wallboard using appropriate fasteners.
What is a stud?
A stud is a vertical framing member used to construct walls to which exterior or interior covering material may be attached. A standard house wall stud is approx 45mm (1-1/2") thick.
Where are the studs in a wall?
Studs are placed for required strength and also for the fixing of 1200mm (4ft) wallboards. Where possible, studs are usually spaced apart 400mm (16") or 600mm (24") from center to center. There is also usually a double stud thickness at the side of a window, door or opening, and also a stud at the corner of any room.
How are the studs found?
Studs can be found by tapping along the wall and listening for a change in sound.
Do the uprights or brackets have to be fixed to the wall studs?
Uprights or brackets can also be fixed to horizontal blocking or even to the wallboard using the appropriate fasteners. However fixing uprights or brackets directly to the center of the wall studs (through the wallboard) will ensure maximum strength.
