Finding wall studs. Wall studs in modern homes are spaced 16 inches on center -- that is thedistance from the center of one wall stud to the center of the next is 16inches. In older homes, studs may be 24 inches apart, or spaced irregularly.
The common wall stud length is 92-5/8. That comes from the desire to use full 96 height dry wall sheets. With ceiling drywall being 5/8 thick and a 96 height full dry wall sheet butted up against it, and 1/2 clearance at the floor to allow for slight variations, you have 97-1/8 wall height.tep 7Install studs along the wall frame. The standard stud spacing is 16 inches. The first stud is placed 16 inches in from the outside edge of the end of the wall. You measure from the outside of the end board 16 inches and the point at which the tape reads 16 inches will be the center of the next stud.
