What size header do I need for a new garage service door

framingstructural

I am going to cut out the wall in my garage under my stairs to build a small room. When I put up the door I have to use a header because it's a load bearing wall. Do I need to make the header out of 2×10, or something else?

Best Answer

For door openings up to 36" (nominal) and for structures with no more than two floors above, it's a safe bet that doubled 2x10s are adequate as a load-bearing header.

Without more detailed information, that's as much as I can say.
