The current Honda Civic Si is 165.7″ long, 66.5″ wide, on a 101.6″ wheelbase, weighing 2,760 lb. Since 1989 it has grown 6% in length and gained 28% in weight. At 13.8 feet it fits a standard garage and fits a street parking space.
Every Honda Civic Si 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 |
|---|---|---|---|---|---|
| 1989–1991 | 156.3″ | 65.7″ | 52.4″ | 98.4″ | 2,161 lb |
| 1992–1993 | 160.2″ | 66.9″ | 53.1″ | 101.2″ | 2,313 lb |
| 2002–2004 | 165.7″ | 66.5″ | 56.7″ | 101.6″ | 2,760 lb |
From 1989 to today the Civic Si gained 9.4″ of length (6%) and 600 lb of weight (28%). A modern compact often outweighs the mid-size car of a generation before.
Civic Si year by year
Measured every model year, not just at generation changes — 8 years on record. Small moves inside a generation are facelifts; the jumps are new platforms.
| Model year | Length | Width | Wheelbase | Curb weight | Body styles |
|---|---|---|---|---|---|
| 2004 | 165.7″ | 66.5″ | 101.6″ | 1 | |
| 2003 | 165.7″ | 66.5″ | 101.6″ | 1 | |
| 2002 | 165.7″ | 66.5″ | 101.6″ | 1 | |
| 1993 | 160.2″ | 66.9″ | 101.2″ | 1 | |
| 1992 | 160.2″ | 66.9″ | 101.2″ | 1 | |
| 1991 | 157.1″ | 66.5″ | 98.4″ | 1 | |
| 1990 | 156.3″ | 65.7″ | 98.4″ | 1 | |
| 1989 | 156.3″ | 65.7″ | 98.4″ | 1 |
Will a Civic Si 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 | 13.8 ft | Fits, with room to open the door |
| Street parking space | 18 ft | 13.8 ft | Fits comfortably |
| Standard parking bay width | 8.5 ft wide | 5.5 ft | Room to open doors both sides |
Against cars of the same length
Compared with 464 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 | 66.5″ | 68.1″ | -1.6″ |
| Wheelbase | 101.6″ | 99.2″ | +2.4″ |
| Curb weight | 2,760 lb | 2,840 lb | -80 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.
