i would say 12" as a guess only if its 2 storeys ,if single storey mininmum 6" to accomadate door fittings to side and 12" middle pillar for ease and depends of building structure.
framed doors need 3" either side if fitted behind brick/blockwork.
ive fitted garage doors for 25 years and know the good the bad and ugly of them on the market .
two storeys get an architect to answer.
