Crew cab vs. extended vs. regular cab: understand truck cab sizes
July 06 2026,
When comparing different types of truck cabs, we’re usually looking to figure out which cab size is best suited to our everyday life. In the Canadian market, cab names vary by brand. At Chevrolet and GMC, you will mostly see regular or standard cab, double cab and crew cab. Whatever the name, the idea remains simple: the larger the cab, the more passenger room you get. What gets tricky is that not all cabs are available with the same cargo bed lengths.
The cab you choose is not only about seating more people. It also affects how easily you can install a car seat for your child, the amount of space for your tools behind the front seats, the length of materials you can load in the cargo bed, and overall comfort on the way to the jobsite, the cottage or the campground. With Chevrolet and GMC, cab formats are well divided across the truck families: 1500 and HD models still offer a real range of options, while modern midsize trucks lean more toward the crew cab, given their frequent use as a primary and family vehicle.
If you are unsure, you can always come discuss it with our experts at GM Paillé in Lanaudière, at GM Paillé Berthierville or GM Paillé Sorel‐Tracy. We will gladly answer your questions and guide you toward the truck configuration perfectly suited to your needs.

The regular cab
The regular cab, sometimes also referred to as the classic cab, is the smallest cab size. On the 2026 Chevrolet Silverado 1500 and 2026 GMC Sierra 1500, it seats 3 passengers, giving you a 2-door truck. It can be paired with a standard cargo bed measuring 79.44 inches or a long cargo bed of 98.18 inches, depending on the model. In HD trucks, such as the Chevrolet Silverado 2500 HD and the GMC Sierra 2500 HD, the regular cab is also offered with 3-passenger capacity, and with the long cargo bed.
If the exact configuration seems complicated, contact us at GM Paillé. We know trucks inside and out. We will help you identify your needs quickly and find the best cab to meet them.
Practically speaking, the regular cab will suit you if you want to maximize cargo bed space and keep a work-focused truck. For a contractor, work on a construction site, hauling materials, utility towing or those of you who often drive solo or as a pair, it is a logical configuration. You sacrifice rear space, but you get a simple and robust formula that works very well for tools, long materials and repetitive tasks.
The extended cab (or double cab)
The extended cab is the perfect compromise between work and versatility. With Chevrolet and GMC, this format generally corresponds to the double cab. On the 2026 Chevrolet Silverado 1500 and 2026 GMC Sierra 1500, it is rated for 6 passengers and pairs with a standard cargo bed of about 79.4 inches. In HD models, you can even get it with a long or a standard cargo bed depending on the model.
You will generally prefer this cab size if you want a true 4-door truck, but you don’t always need the second row.
Pro advice
For fishing, camping, weekends at the cottage or work-leisure dual-purpose use, it allows you to opt for a longer bed while also adding a covered rear area that is useful for your bags, coats, tools or occasional passengers.

The crew cab
The crew cab is the most sought-after by families and by shoppers who use their truck as their primary vehicle. On the 2026 Chevrolet Silverado 1500 and 2026 GMC Sierra 1500, it seats 6 passengers and can be paired with a short cargo bed or a standard cargo bed. It offers generous headroom and legroom, which helps explain why this cab size has become the reference for long drives, kids and year-round daily life.
It is also the format that dominates modern midsize trucks, such as the 2026 Chevrolet Colorado and 2026 GMC Canyon. It gives you all the space you need, and everyone will be comfortable, even rear passengers.
Pro advice
Alexandre Rivest, your sales consultant, explains how the crew cab is the ideal choice for your family:
If you have a family, if your pickup is your main vehicle and you want everyone to be comfortable, it’s a no-brainer: the crew cab is the cab you need.
Extended cab (double cab) vs. crew cab compared
Which should you choose between a crew cab and a double cab? In practice, the most important difference concerns rear space and the truck's overall flexibility. The double cab often keeps a more utilitarian approach: it offers a practical though less spacious second row, but it often allows you to choose a longer cargo bed in several model configurations. The crew cab’s primary focus, on the other hand, is interior space, clearly aimed at rear-passenger comfort and family-oriented versatility.
Which cab to choose for your use?
If you mainly work on job sites, with construction materials, toolboxes, utility towing and few passengers, the choice between a regular cab vs. double cab becomes easier, since the regular cab remains a great solution for professionals. It is still relevant on 1500s and especially on HDs, where cargo bed length and a work-focused purpose often matter more than the comfort of a second row.
If your use is mixed, with work during the week and fishing, camping or the cottage on weekends, the double cab is often the best middle ground. You keep a longer cargo bed, you can still seat rear passengers or store gear behind the first row, but you are not moving into as family-focused a format as the crew cab. If you only need a second row occasionally, it is often a very sensible solution.
If your truck is also your family vehicle, if you have kids or often install a car seat, the crew cab is almost always the best answer. Even without kids, you will choose the crew vs. double cab if you often travel with several people or if your truck serves as your primary vehicle. It is also the easiest format to live with day to day, the most welcoming for the second row and well adapted to an active lifestyle. That is also why it now dominates modern midsize trucks, such as the Colorado and the Canyon.
The configurations offered at Chevrolet and GMC
At Chevrolet and GMC, not all cabs are available on every model. In midsize trucks, your Canyon or your Silverado will automatically come with a crew cab.
In full-size trucks, the choice is much broader. The 2026 Chevrolet Silverado 1500 and 2026 GMC Sierra 1500 offer a regular cab, a double cab and a crew cab, with various cargo bed lengths depending on the chosen combination.
If you move up to HD models, the offering expands even further. Your Silverado 2500HD or 3500HD, or your Sierra 2500HD or 3500HD, will give you a choice among the three cabs, with standard or long cargo beds depending on the cab and the trim. As you can see, the higher you climb in the Chevy and GM truck hierarchy, the more freedom you gain in choosing the cab and cargo bed configuration.
We promise that, even if it may seem complicated, having a quick chat with one of our truck experts at GM Paillé can help you sort it out quickly.
Frequently asked questions about cab types
Does a larger cab reduce cargo bed length?
Often yes, but not automatically. On the 2026 Chevrolet Silverado 1500 and 2026 GMC Sierra 1500, the crew cab is available with a short or a standard cargo bed, while the regular cab keeps combinations more oriented toward longer cargo beds. In HD models, the crew cab can even still be paired with a long cargo bed. You should look at the exact combination, not just the cab name.
Are all cabs available on every model?
No. The 2026 Chevrolet Colorado and 2026 GMC Canyon are offered in crew cab only. In contrast, the Chevrolet Silverado and GMC Sierra 1500, and the Chevrolet Silverado and GMC Sierra HD offer several configurations.
Which cab type to choose with kids?
The crew cab is the best option. It provides the most rear comfort and is the easiest to use when you often drive with kids or teens.
Which cab type to choose for installing a car seat?
Again, the crew cab is the simplest choice. You benefit from a more generous second row and more natural access to install or remove a car seat for your child. A double cab can work, but it is less ideal if this is a frequent need.
Which cargo bed size suits a jobsite best?
For a jobsite, a standard or long cargo bed is often the best solution. That is where regular cabs and some double cabs keep an advantage, especially on 1500 and HD models. If you carry a lot of materials, long tools or bulky equipment, the cargo bed matters as much as the cab size.
Long or short cargo bed for towing?
For towing, the answer always depends on the full configuration, but a longer cargo bed and a longer wheelbase can help with stability with certain trailers. That said, do not choose based on cargo bed alone. The trim, powertrain, towing package and the trailer's actual weight remain decisive factors.
