In conventional framing, which size range of solid lumber is typically used?

• A. 1x4
• B. 4x4
• C. 3x3
• D. 2x6 or larger

Answer: (D)

In conventional framing, the structural members are chosen for enough cross-sectional area to carry loads and resist bending. That typically means lumber in the range of at least 2 inches by 6 inches, or larger, since this size provides the necessary strength for studs, joists, and other framing members. Smaller options like 1x4 or 3x3 are not suitable for main framing tasks, and while a 4x4 can be used for posts, it isn’t representative of the common framing lumber used across the majority of the structure. So, the standard range you’ll see in practice is 2x6 or larger.
