BMW 3 Series Saloon dimensions that matter for a garage
The mirror-to-mirror width is significant enough that a narrow garage door can be the limiting point even when the body fits easily inside. Length is also important: with a vehicle around 4.7 metres or more, door closure, shelving and access to the boot can consume the remaining depth quickly.
The reference width with mirrors extended is 2,068 mm. For the entrance check, use the narrowest clear width of the garage door at mirror height, not the nominal door size.
Illustrative garage-door clearance
These examples compare the reference vehicle width with three clear opening widths. They are examples only — use the width you physically measure at your own door.
| Clear door opening | Mirrors extended | Mirrors folded |
|---|---|---|
| 2,134 mm | 66 mm | Confirm folded width |
| 2,286 mm | 218 mm | Confirm folded width |
| 2,438 mm | 370 mm | Confirm folded width |
Clearance shown is total width, not clearance on each side. A positive number does not mean the opening will be comfortable to use.
What could stop it fitting even when the numbers look positive?
A garage rarely behaves like a perfect rectangular box. Door tracks, frame trim, masonry that narrows at one height, an up-and-over mechanism, pipework, shelving and stored equipment can all reduce the usable space. The car also needs to be positioned accurately as it enters. For daily use, the ability to open the driver's door may matter more than the final few centimetres of theoretical side clearance.
Measure the clear door width at mirror height, the lowest entrance obstruction, the usable internal width after shelving and pillars, and the usable depth with the door closed. Then use the full calculator rather than relying on a generic garage size.

BMW 3 Series Saloon garage-fit FAQs
Will a BMW 3 Series Saloon fit through a 7 ft garage door?
Using the 2,068 mm reference mirror width on this page, a 2,134 mm clear opening is wider by about 66 mm in total. That only answers the width question; height, alignment and exact vehicle specification still need checking.
How much internal garage width does a BMW 3 Series Saloon need?
The reference body width is 1,827 mm, but a usable garage needs additional space for door opening, positioning and any shelving or pillars. The calculator lets you enter the internal width and obstructions separately.
How long a garage does a BMW 3 Series Saloon need?
The reference overall length is 4,709 mm. The garage must be longer than that, but useful clearance also depends on the closed door, shelving, pipes and whether you need access to the boot or tailgate.
