This post describes the building code rules around framing, which are the studs in your walls, the joists in your floors and ceilings, and that which supports them.
The Solera Group provides expert bathroom remodeling services in the greater San Jose metro area
- Beams hold up your house. They sit on the foundation perimeter and pier blocks. They are typically 6×8 lumber, sometimes larger.
- Joists sit on the beams. They are 2×6 lumber standing on end. The subfloor is attached to the top of the joists.
- Studs go up and down your walls. In fact the wall materials (almost always sheet rock) attaches to the studs.
Joists are installed 24 inches on center, which is to say the center of one joist is 24 inches from the center of the next.
Studs are installed 16 inches on center.
Why? Because we’ve standardized that sheets of building material (sheetrock, plywood, some forms of siding) come in 4×8 sheets. Since each sheet needs to install joist to joist or stud to stud, we’ve decided on 24 inches (1/2 the width of a sheet) and 16 inches (1/3 the width of a sheet) for separation.
How did this come to be? What does it matter? We live with these dimensions now. To pass inspection, you install your framing at those dimensions.
Is it ever different?
Yes. Door and windows have special framing requirements which are beyond the scope of this post, but you can easily find that information elsewhere.
