A comparison of the crew cab vs. double cab, including key differences between both models, as well as which body style may be better for you.

Crew Cab Vs Double Cab

If you are thinking about getting behind the wheel of a truck, you have a lot of decisions to make. Do you want a gas-powered, diesel or electric truck? Do you know what truck bed size you want? How about the cab configuration – have you considered the differences between the Crew Cab vs. Double Cab designs?

In our guide, we cover all of the top differences between the two cab styles. We also show you what four cab sizes are available with today’s trucks and we help you figure out which one might be best for your needs. At the end of our article, your top cab style questions are answered. 

Crew Cab vs. Double Cab: What are the Differences?

The biggest difference between the crew cab vs. double cab is the interior dimensions, but so is the door configuration. Additionally, the cab style can affect the performance and what bed sizes are available. Finally, you are looking at a minimal difference in price between the two. 

Here is more detailed information on the differences between the Crew Cab and Double Cab:

1. Interior Dimensions

Pickup Truck Rear Interior

The biggest difference between the two truck types is the interior dimensions. Double Cabs are also called Extended Cabs, but they are smaller inside than the Crew Cab. 

As an example, let’s look at the interior dimensions of a Chevy Silverado. Here’s what you find with a 2020 Double Cab truck. 

  • 2nd-row headroom: 39.88 inches
  • 2nd-row legroom: 35.24 inches

Here are the dimensions of a Crew Cab model.

  • 2nd-row headroom: 40.12 inches
  • 2nd-row legroom: 43.40 inches

With that said, the front headroom and legroom remain the same among both truck configurations. 

2. Door Configuration

The other big difference is how the doors are set up. Both trucks technically come with a four-door design, but one looks starkly different than the other.

The Crew Cab model will have four full-size doors, so rear passengers can get into the truck without opening other doors. On the other hand, the Double Cab may have rear doors that require the front doors to be opened first. The handle may be hidden inside, but not always. It can also have four normal doors, but the rear doors will be much smaller than on the Crew cab.

Additionally, they aren’t always full-size. Otherwise, there are some Extended Cab trucks with a two-door design that leads into a larger cabin than the Regular Cab. 

3. Performance

Typically, you aren’t going to notice any performance difference between the two trucks. Most manufacturers offer the same powertrain options between the Double and Crew Cab configurations.

You should be able to choose from a multitude of gas- and diesel-powered motors, depending on what’s available with that model. For this reason, most people choose the configuration before deciding on the powertrain. 

4. Bed Size

Pickup Truck Bed

What manufacturers will dictate based on the cab configuration is the truck bed that goes with it. The longer the cab, the less likely you are to get a big truck bed to match. 

Because the truck still needs to be maneuverable, you can’t normally get big on both fronts. Either you will have a larger cabin and a smaller bed or vice versa. 

5. Price 

In general, the Crew Cab costs more than the Double Cab when comparing everything else apples-to-apples. If you want the same powertrain, features and style, the Crew Cab will cost you minimally more money.

With that said, it’s also going to have a higher resale value. When you go to sell your truck, you can get more for it with a Crew Cab configuration. 

4 Truck Cab Styles

1. Regular Cab

The Regular Cab truck contains a two-door design that usually has one row of seats. Because the cab is smaller, the truck can normally accommodate the largest bed size from the manufacturer. That’s why they are a good option for anyone using the truck to work. 

Here is what some of the top manufacturers call their Regular Cab trucks.

  • Chevrolet: Regular Cab
  • Ford: Regular Cab
  • GMC: Regular Cab
  • RAM: Classic/Regular Cab
  • Nissan: Single Cab
  • Toyota: Regular Cab

Most major manufacturers offer a single cab design in their lineup. However, these are becoming less popular over time. 

2. Extended Cab

The Extended Cab can have a two- or four-door design. Still, there will be some sort of back row, although it could be smaller than what’s found in a Crew Cab truck. 

Here is what some of the top manufacturers call their Extended Cab trucks.

  • Chevrolet: Double Cab
  • Ford: SuperCab
  • GMC: Double Cab
  • RAM: Quad Cab
  • Nissan: King Cab
  • Toyota: Access Cab

With these trucks, you normally have the option to choose a larger or smaller truck bed size. For this reason, the Extended Cab can offer a nice balance between interior comfort and practicality.

3. Crew Cab

This is a truck that features four full-size doors. They offer the largest cabin in the standard truck configuration. Most of the trucks provide seating for up to six in these cabins.

Here is what some of the top manufacturers call their Crew Cab trucks.

  • Chevrolet: Crew Cab
  • Ford: SuperCrew
  • GMC: Crew Cab
  • RAM: Crew Cab
  • Nissan: Crew Cab
  • Toyota: Double Cab

Because the cabin takes up more space, it’s difficult to find larger truck beds with these options. You must sacrifice cargo carrying capacity to increase the second-row accommodations. 

4. Extended Crew Cab

Most people don’t know that there’s another size for the standard Crew Cab truck. Some manufacturers now offer something a little larger than your regular four-door truck. If you want a little extra room to stretch out, you might prefer these options.

Here is what some of the top manufacturers call their Extended Crew Cab trucks.

  • RAM: Mega Cab
  • Toyota: CrewMax

However, you aren’t going to get the biggest bed size with any of these. Still, if comfort is a top priority, it could be worth paying more for these models. 

Which is Best for You? Crew Cab or Double Cab

Picking the right truck cab depends solely on what your needs are. For example, the Regular or Single Cab design is going to be best for drivers that need a work truck with the biggest bed length possible. For these drivers, interior comfort and features aren’t high on the priority list. 

On the flip side, the Crew Cab truck is ideal for anyone that wants to offer superior comfort to passengers who might be along for the ride. The interior is going to be spacious and it’s easy to get all of the features you desire. However, the bed length will be smaller, so cargo space is compromised.

In the middle of these two options is a nice balance with the Extended or Double Cab truck. It offers more passenger space than the Regular Cab but can also be equipped with a longer truck bed because it’s not a full-size cabin. 

FAQs

Is My Truck a Quad or Crew Cab?

How Do I Know What Kind of Cab My Truck Is?

Are Crew Cab and Double Cab Seats the Same?

In a Crew Cab and Double Cab truck comparison, you will find that both offer a back seat. The difference is that there is slightly more space in the Crew Cab than in the Double Cab.

Why are Crew Cab Trucks So Popular?
