Framing & StructuralQuestion 376 of 700
For a conventionally framed one-story dwelling using 2x4 studs, what is the MAXIMUM on-center spacing generally permitted for load-bearing wall studs supporting a roof and ceiling only?
a.12 inches
b.24 inches
c.32 inches
d.48 inches
Explanation
The residential code stud tables allow 2x4 bearing studs supporting roof and ceiling to be spaced up to 24 inches on center. 12 inches is more conservative than required and wastes material; 32 and 48 inches exceed the tabulated maximum for 2x4 bearing studs and would over-stress the wall.
