How do you frame a 9x7 garage door?

To frame a 9x7 garage door, you'll need a header. For a 9-foot opening, a common header size is two 2x10s with a 1/2-inch plywood spacer, or a single LVL beam. Ensure cripple studs support the header, and king studs extend from the bottom plate to the top plate, with jack studs supporting the header.
