Ever heard someone say “That’s a C-segment hatch” and pretended to nod along? You’re not alone. Car size segments like A-segment, B-segment and beyond can sound like car expert code, but they actually tell you a lot about what a car’s like to drive and own.

I've written this guide to explain each category in plain English, with real-world examples.

A‑Segment: City Cars

A-segment cars are the smallest vehicles on the road, typically under 3.7 metres in length. Designed for dense urban driving, they’re ideal for tight parking, low running costs, and short trips. Popular models include the Fiat 500, Volkswagen Up!, and Hyundai i10. They won’t carry a family of five in comfort, but for solo drivers or city couples, they’re ideal.

B‑Segment: Superminis / Subcompact Cars

The B-segment includes slightly larger hatchbacks and small saloons. These cars generally measure between 3.8 and 4.1 metres. They offer more practicality without sacrificing a city-friendly size. The Ford Fiesta, Volkswagen Polo, and Peugeot 208 are typical examples. This is one of the most popular segments in the UK thanks to its affordability and flexibility.

C‑Segment: Compact Cars

Often referred to simply as “family hatchbacks”, C-segment cars typically measure between 4.2 and 4.5 metres. This size is considered the most versatile for a broad range of buyers—spacious enough for families, small enough for most driveways. The Volkswagen Golf, Honda Civic, and Toyota Corolla define this class across global markets.

D‑Segment: Midsize or Large Family Cars

Moving up a notch, D-segment cars range from around 4.6 to 4.9 metres in length. These are your larger saloons and estate cars—offering more rear legroom, boot space, and comfort for long-distance driving. Think BMW 3 Series, Toyota Camry, and Volkswagen Passat. Though less dominant now than SUVs, they remain a go-to for drivers who value refinement and space.

E‑Segment: Executive Cars

This is where luxury kicks in. E-segment models stretch between 4.9 and 5.2 metres, providing high levels of passenger comfort, upmarket materials, and often powerful engines. Popular models include the BMW 5 Series, Mercedes-Benz E-Class, and Audi A6. These are the cars of choice for long motorway journeys and business-class commuters.

F‑Segment: Full‑Size Luxury

F-segment cars are flagship luxury saloons, usually over 5.2 metres long. These models prioritise rear-seat space, smoothness, and features you’d expect in a private jet—massaging seats, reclining rear benches, and ultra-quiet cabins. Examples include the Mercedes-Benz S-Class, BMW 7 Series, and Audi A8. They're less common on UK roads but still represent the pinnacle of traditional luxury.

How SUVs Fit Into These Segments

SUVs and crossovers align loosely with these categories, but instead of ‘LETTER-Segment’, they’re often grouped by size labels. Subcompact SUVs like the Ford Puma and Hyundai Kona fall under the B-segment umbrella. Compact crossovers such as the Toyota RAV4 or Honda CR-V line up with the C-segment. Mid-size SUVs like the Ford Edge or Volkswagen Tiguan Allspace equate to the D-segment, while larger models such as the Chevrolet Tahoe or Land Rover Discovery enter F‑Segment territory.

Why Size Segments Matter

Understanding size segments helps you quickly judge whether a car suits your space, your budget, and your lifestyle. Smaller segments mean better manoeuvrability and lower costs, while moving up the range brings comfort, tech, and prestige—but also larger footprints and higher prices.
