When installing a garage door what leg height is needed?

If you’re installing a garage door centered on the front or back end (width of building) then the leg height (side height of the building) can be the same height as the garage door installed on the center end (width of the building).

If you’re installing two garage doors on the front or back side of the building then depending on width of building the legs need to be at least 1 foot taller than the doors. If you’re installing a garage door on the side (length of building) then the legs need to be at least I foot taller than the garage doors.
