Every Buick Roadmaster generation, measured
One row per generation. Watch the weight column — that is where most of the change happens for the Buick Roadmaster, 0 lb of it since 1991, and it is the number that decides fuel use, tyre wear and how far the car takes to stop.

|---|---|---|---|---|---|
| 1991–1996 | 216.9″ | 79.1″ | 57.5″ | 115.7″ | 4,239 lb |

Will a Roadmaster fit
The practical question behind every dimensions search, and for a 18.1-foot Buick Roadmaster it has a straight answer. A single-car garage in the US is typically 20 feet deep and a street parking space about 18, so the Roadmaster clears the garage by 0.9 ft. We allow a foot of clearance in both — nobody parks to the millimetre.
| Space | Typical size | This car | Verdict |
|---|---|---|---|
| Single garage | 20 ft deep | 18.1 ft | Fits, with room to open the door |
| Street parking space | 18 ft | 18.1 ft | Overhangs — expect a tight squeeze |
| Standard parking bay width | 8.5 ft wide | 6.6 ft | Room to open doors both sides |
Against cars of the same length
Compared with 242 vehicles within ten inches of the same length — a fair proxy for «cars of this size», regardless of what the marketing calls them.
| Measure | This car | Typical car of this length | Difference |
|---|---|---|---|
| Width | 79.1″ | 77.6″ | +1.5″ |
| Wheelbase | 115.7″ | 126″ | -10.3″ |
| Curb weight | 4,239 lb | 4,733 lb | -494 lb |
A longer wheelbase for the same overall length means shorter overhangs — usually more cabin space and a steadier ride. At 4,239 lb the Buick Roadmaster is 494 lb lighter than typical for its size, which generally shows up as fuel economy and stopping distance.

How we measure
Dimensions come from NHTSA vPIC and Transport Canada vehicle records — manufacturer-declared figures, held in metric and converted to inches and pounds for display, 6 measured model years for the Buick Roadmaster between 1991 and 1996.
One row per generation, not per model year: manufacturers rarely change the body between facelifts, and the Buick Roadmaster fits into 1 rows instead of 6. Where a generation offered several body styles, the figures are the base measurements for that generation of the Buick Roadmaster.
