For a 2x4 stud (width 3.5 inches), the maximum notch depth is approximately how many inches?

Explanation:
Notching a stud reduces its load-carrying capacity, so depth is limited. For a standard 2x4 stud, the width is 3.5 inches, and the typical limit for a notch in a load-bearing stud is 25% of that width. So 25% of 3.5 inches is 0.875 inches, meaning the maximum notch depth is about 7/8 of an inch. The other options are either shallower than the limit or exceed it, with depths of 1.0 or 1.25 inches going beyond what’s allowed without reinforcement.
