What is the minimum end bearing required for headers in wood frame walls?

1. One inch

2. One and one-quarter inches

3. One and one-half inches

4. Two inches

The correct answer is: One and one-half inches

The minimum end bearing required for headers in wood frame walls is one and one-half inches. This standard is established to ensure adequate support for the structural loads transferred from the header to the supporting elements, typically the top plate or studs of the wall. Having a minimum bearing requirement helps to prevent potential structural failure or sagging over time. In wood frame construction, proper bearing ensures that the load is distributed evenly and effectively throughout the structure. Therefore, headers must rest adequately on the supporting members to maintain overall integrity. While other options represent potential bearing measurements, they do not meet the established minimum standards set by building codes and construction best practices for headers, which prioritize safety and structural performance.
