Final answer:
A standard interior door jamb width usually accommodates a 3-1/2 inch stud wall with 1/2 inch drywall on both sides, totaling approximately 4-9/16 inches.
Step-by-step explanation:
The width of a standard interior door jamb depends on the wall thickness and is typically about 4-9/16 inches, which allows for 1/2-inch drywall on both sides of a 3-1/2 inch stud wall. In some cases, such as when the walls are thicker due to double drywall or other finishes, the jamb can be wider. It is essential to measure the actual wall thickness for a precise fit.
