The current Mercedes-Benz 300 is 187.4″ long, 68.5″ wide, on a 110.2″ wheelbase, weighing 3,373 lb. At 15.6 feet it fits a standard garage and fits a street parking space.
Every Mercedes-Benz 300 generation, measured
One row per generation. Watch the weight column — that is where most of the change happens, and it is the number that decides fuel use, tyre wear and how far the car takes to stop.
| Generation | Length | Width | Height | Wheelbase | Curb weight |
|---|---|---|---|---|---|
| 1971–1972 | 196.9″ | 71.3″ | 55.9″ | 112.2″ | 3,955 lb |
| 1975–1976 | 195.7″ | 69.7″ | 56.7″ | 108.3″ | 3,450 lb |
| 1977–1985 | 190.9″ | 70.5″ | 56.7″ | 109.8″ | 3,514 lb |
| 1986–1993 | 187.4″ | 68.5″ | 57.1″ | 110.2″ | 3,373 lb |
300 year by year
Measured every model year, not just at generation changes — 21 years on record. Small moves inside a generation are facelifts; the jumps are new platforms.

Will a 300 fit
The practical question behind every dimensions search. A single-car garage in the US is typically 20 feet deep; a street parking space is about 18. We allow a foot of clearance in both — nobody parks to the millimetre.
| Space | Typical size | This car | Verdict |
|---|---|---|---|
| Single garage | 20 ft deep | 15.6 ft | Fits, with room to open the door |
| Street parking space | 18 ft | 15.6 ft | Fits comfortably |
| Standard parking bay width | 8.5 ft wide | 5.7 ft | Room to open doors both sides |
Against cars of the same length
Compared with 1,034 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 | 68.5″ | 72.8″ | -4.3″ |
| Wheelbase | 110.2″ | 109.1″ | +1.1″ |
| Curb weight | 3,373 lb | 3,743 lb | -370 lb |
A longer wheelbase for the same overall length means shorter overhangs — usually more cabin space and a steadier ride. Lighter than typical for its size generally means better fuel economy and shorter stopping distances.

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.
One row per generation, not per model year: manufacturers rarely change the body between facelifts, and a table of forty near-identical rows helps nobody. Where a generation offered several body styles, the figures are the base measurements for that generation.
