The width of a car, specifically the most common Fortwo model, is 61.4 inches (5.12 feet or approximately 155.9 cm). This measurement is for the body itself, not including the side mirrors. When you include the mirrors, the total width increases to about 77.3 inches (6.44 feet or 196.3 cm). This compact width is the car's defining feature, making it exceptionally easy to park and maneuver in tight urban environments where space is at a premium.
To put this into perspective, the average mid-size sedan in the U.S., like a Toyota Camry, is over 72 inches wide without mirrors. The Smart Fortwo's narrow footprint allows it to fit into parking spots that are impossible for most other vehicles. You can often park it perpendicular to the curb in a standard parallel parking space.
| Smart Car Model & Generation | Width (Body) | Width (with Mirrors) | Key Contextual Comparison |
|---|---|---|---|
| Fortwo (451 generation, 2008-2015) | 61.4 inches / 155.9 cm | 77.3 inches / 196.3 cm | Narrower than a Honda Civic by over 11 inches. |
| Fortwo (453 generation, 2016-2019) | 65.5 inches / 166.3 cm | 80.9 inches / 205.5 cm | Newer model is wider but still significantly smaller than average. |
| Average U.S. Mid-Size Sedan | ~73 inches / 185 cm | ~82 inches / 208 cm | Highlights the Smart car's unique size advantage. |
| Standard Parking Space Width | ~96 inches / 244 cm (8 feet) | N/A | Shows how much space remains when parked. |
This design prioritizes city agility over highway stability or interior spaciousness. While the cabin is surprisingly tall, the narrow width means you sit very close to your passenger. The primary trade-off for its parking prowess is that it can feel buffeted by strong crosswinds on the highway and has a tighter cabin feel than a traditional car.

I drive a Fortwo in the city, and the width is the whole point. It’s just over five feet wide. You stop worrying about finding a "parking spot" and start just looking for any gap big enough to squeeze into. I’ve pulled into spaces between two cars where I had inches to spare on each side. It completely changes how you navigate crowded streets. The trade-off? It feels a bit tippy next to big trucks on the freeway.

From an standpoint, the Smart Fortwo's width of approximately 1.66 meters for the final generation was a deliberate packaging decision. The Tridion safety cell is designed to be exceptionally rigid within this narrow track. The main challenge with this architecture is managing dynamics; the short wheelbase and narrow stance require specific tuning of the suspension and electronic stability control to ensure safe handling, particularly during evasive maneuvers or in high winds.

Think of it this way: a standard parking space is about 8 feet wide. A car is only about 5 feet wide. That means when you park it, you have a solid 3 feet of space left over—that's like having an entire extra bicycle lane next to your car. It’s not just about fitting into a small spot; it’s about being able to open your doors fully without dinging the vehicle next to you. For city living, that’s a huge quality-of-life feature.

I remember when my daughter bought one. I was skeptical until I saw her park it. She just slid it right into a spot that looked more like an alleyway. I asked her how wide the thing was, and she said, "Narrower than your garden shed, Dad." She wasn't wrong. It’s that kind of car—it makes sense the moment you see it in a real-world situation. It’s designed for a specific purpose, and it excels at it. You buy it for the parking, plain and simple.
