distance between track mounting brackets should be door width plus 3" at minimum but no more than door width plus 4". At 4" it'll be sloppy. 3-1/4 to 3-1/2 is the sweet spot.
For most standard doors, you'll need at least 10 to 12 inches of headroom. For a garage door opener, you might need additional space, generally around 14 inches. On the sides, you should have at least 3.75 inches of space on each side of the door opening for the vertical track.
There should be a 2mm or 3mm gap between the door and the frame on both sides and the top. If you do need to cut the door down to size, keep in mind that you need to cut all four sides of the door equally whenever possible to retain an accurate shape or pattern if the door is panelled.
To answer the question posed earlier, a garage door can't be wider than the opening. In fact, your garage door should be the same size as the opening, or maybe even a hair smaller. Also, the rough opening should be a few inches wider than the door to accommodate the frame to ensure a tight fit with a seal.

Other openings between the garage and residence shall be equipped with solid wood doors not less than 13/8 inches (35 mm) in thickness, solid or honeycombcore steel doors not less than 13/8 inches (35 mm) thick, or 20-minute fire-rated doors, equipped with a self-closing and self-latching device.
