People say modern cars are enormous and it usually gets treated as nostalgia. I averaged the dimensions in our specification data by era instead.
| Era | Average height | Average width |
|---|---|---|
| Before 2005 | 148 cm | 179 cm |
| 2015 and later | 158 cm | 190 cm |
Ten centimetres up, eleven across
Roughly four inches in each direction. That's not a handful of oversized models dragging an average — it's the whole fleet moving, because the mix moved. Sedans lost share to crossovers, and a crossover is a taller, wider car by definition.
But the individual models grew too. Nearly every nameplate that survived twenty years is larger now than the car that carried the name in 2004, because each generation adds a little for crash structure, for cabin space, for the styling of the moment. Nothing ever shrinks between generations.
Where the extra size comes from
Crash regulations. Side-impact protection means thicker doors and more structure in the pillars. Some of that width is beam and airbag, not interior space.
Ride height sells. Buyers report feeling safer sitting higher, and manufacturers sell what buyers ask for. The seating position is the product.
Wheels got bigger. Larger diameter wheels with lower-profile tyres need more arch clearance, pushing the body outward.
Batteries and hardware. Electrified powertrains need packaging space, usually under the floor, which pushes the roofline up.
What four inches costs you
Parking spaces didn't grow. Standard US spaces are a legacy of 1970s dimensions. A 190 cm car in a space designed for 179 cm cars is why door dings have become a permanent condition.
Visibility got worse, not better. Higher bonnets and thicker pillars create larger blind zones directly in front of and beside the car. This is precisely why reversing cameras became mandatory in 2018 — and why they immediately became one of the most recalled systems in the country, as we found in what cars get recalled for now.
Repairs cost more. More panel area, more sensors embedded in it, more calibration after replacement. Bigger cars are more expensive to fix even in identical collisions, which feeds directly into the insurance increases we tracked in the 20% rise in three years.
Garages became a real constraint. Older houses have garages sized for older cars. Plenty of modern vehicles technically fit and leave no room to open a door.
If you want a smaller car
The used market is where they live. A pre-2010 vehicle is on average four inches narrower, and the segments that have since disappeared — compact sedans, small wagons, genuinely small hatchbacks — are still available there in volume.
They're also cheaper to run, cheaper to insure and easier to park. What you give up is crash structure, and the mass that came with it: we tracked that in today's Honda Civic outweighs a 1981 Mustang. Whichever way you go, a VIN check confirms what the specific car actually is before you commit.
Frequently asked questions
How much bigger have cars got?
Average height rose from 148 cm on pre-2005 models to 158 cm on 2015-and-later ones, with width up from 179 cm to 190 cm — roughly four inches in each direction over two decades.
Why are modern cars so wide?
Side-impact regulations require thicker doors and more structure in the pillars, larger wheels need more arch clearance, and the market shift from sedans to crossovers moved the whole average upward and outward.
Do bigger cars cost more to repair?
Yes. More panel area, more embedded sensors and mandatory recalibration after replacement mean higher repair bills for identical collisions — one of the drivers behind rising comprehensive insurance premiums.
Where can I find a smaller car?
The used market. Pre-2010 vehicles average four inches narrower, and segments that have since disappeared — compact sedans, small wagons and genuinely small hatchbacks — are still widely available there.

The V8 Is Now Outnumbered Four to One
There was a time when a family saloon came with six cylinders and a truck came with eight. I counted what's actually in our catalogue by engine layout, and the middle of the market has quietly collapsed into one configuration.
The Feature Everyone Switches Off Is Now on 63% of New Cars
Start-stop is the most disliked feature in modern motoring — the first thing owners turn off every morning. It went from 4% of new models to 63% in twelve years, and there's a specific reason it spread despite everyone hating it.
Kia Has More American-Built VIN Codes Than Ford
The first digit of a VIN tells you where the car was assembled, not what the badge suggests. I went through the manufacturer code registry brand by brand, and the phrase "buy American" turns out to be much harder to act on than it sounds.
