What are different cab sizes?
Pickup trucks come in several cab sizes that affect seating, doors, and cargo space. The main options are Regular Cab, Extended Cab, and Crew Cab, with a few brands offering larger or specially named variants.
Common cab-size categories
Below is a quick guide to the three core cab configurations you’ll encounter, along with notes on what each means for passenger space and cargo access.
- Regular Cab – Typically two doors and two or three seats; the smallest cabin and the longest available cargo bed behind the cab. Best for work crews who need maximum cargo space behind the cab and do not require rear-seat access.
- Extended Cab – Also called Quad Cab or Double Cab on some models; four doors, but rear doors are smaller or half-height, with more rear seating than a regular cab. A compromise between cargo length and passenger space.
- Crew Cab – Also called Crew or CrewMax depending on brand; four full-size doors and abundant rear-seat space; more convenient for families or crews who need frequent passenger access.
- Large/extra variant families (rare) – Some models offer even more rear-seat space with names like Mega Cab or Max Cab, though these are not widely available and are model-specific. They provide the most rear legroom at the expense of some cargo length behind the cab.
Understanding these categories helps when comparing models, because the cab size directly affects passenger comfort, rear-seat accessibility, and the amount of space available behind the cab for cargo.
Brand naming and how to compare
Because automakers use different terms for the same concepts, it helps to know the general naming patterns rather than rely on a single label. Here are the core ideas:
- Regular Cab: two doors, minimal rear seating; typically offers the longest bed length.
- Extended Cab (Quad/Double Cab): four doors with reduced rear-door size or access; more seating than a Regular Cab.
- Crew Cab (Crew/CrewMax): four full doors; best rear-seat comfort and access.
- Specialized large variants (Mega/Max/King Crew, etc.): high-end or model-specific options that push rear-seat space further; availability varies by model and year.
When shopping, verify the actual door count, seating capacity, rear legroom, and the cargo length behind the cab to match your needs.
Summary
Across pickups, the cab choices you’ll encounter most often are Regular Cab, Extended Cab, and Crew Cab. Some models add extra-large variants for maximum rear-seat space. Always check door configuration and measurements for seating and cargo to ensure the configuration fits your daily use.
