Which statement is the minimum grade for bearing studs?

• A. No. 2 standard or stud grade
• B. No. 4 standard or stud grade
• C. No. 1 standard or stud grade
• D. No. 3 standard or stud grade

Answer: (D)

Bearing studs must carry vertical loads from above, so they need enough strength and quality to resist bending and defects. The minimum grade that provides that level of structural reliability is No. 3 standard or stud grade. That means any lumber rated No. 3 or better is acceptable for bearing studs, while lumber graded No. 4 would be too weak for the required load-bearing function. Higher grades like No. 2 or No. 1 are permissible, but they exceed the minimum. Using No. 3 sets the baseline for ensuring the studs can reliably support the structure above doors, windows, and bearing walls.
