The 2021 Ram 1500 is one incredible vehicle. This model offers some class-leading capabilities and power output, making it a go-to one for those who like to partake in all kinds of adventures. To make your journeys possible, the Ram 1500 was designed with meticulous interior and exterior dimensions.

In this Ram 1500 dimensions guide, we at Rockwall CDJR will give you a detailed breakdown of this model’s interior and exterior dimensions. Shoppers in Rockwall, Terrell, Rowlett, and Wylie, TX, should read on to learn more about the Ram 1500’s size and shape!

Interior Dimensions

Expansive Interior Dimensions

The 2021 Ram 1500 gives you a choice between two different cab options, including a Quad Cab and a larger Crew Cab. No matter which one you choose, you’ll have five standard seats.

However, both cabs also offer available seating for up to six passengers, giving each passenger plenty of room with the following interior dimensions:

Quad Cab Crew Cab
Front / Rear Headroom 40.9 inches / 39.2 inches 40.9 inches / 39.8 inches
Front / Rear Hip Room 63.4 inches / 63.4 inches 63.4 inches / 63.4 inches
Front / Rear Legroom 40.9 inches / 35.6 inches 40.9 inches / 45.2 inches
Front / Rear Shoulder Room 66.0 inches / 65.7 inches 66.0 inches / 65.7 inches

As you can see, both models are impressively spacious. With its 45.2 inches of best-in-class rear legroom, the available Crew Cab is the ideal choice for those who plan to spend time with their Ram 1500 at the worksite. The whole crew will be begging to climb inside your high-end pickup truck.

This isn’t to say that the standard Quad Cab is a less-than-worthy option for DIYers and worksite-to-weekenders. However, its slightly smaller cab design may be better suited for your growing and adventurous family. The kids will have plenty of room to make memories in the backseat on the way to the campground or the lake during fishing season.

For more room, you’ll be able to opt for several class-exclusive adjustment features for the rear row of seats. Opt for available reclining rear seats and under-seat storage.

Various Cargo Options

The cabin of the 2021 Ram 1500 isn’t just designed with passenger dimensions in mind—it also offers a wide range of in-cabin cargo storage options. In total, the Ram 1500 offers more than 151 liters of cargo space inside the vehicle along with various available cargo options.

Rather than giving up your legroom in the rear row, opt for available in-floor storage. This option provides you with the storage you need for smaller cargo items, like backpacks, lunch boxes, and overnight bags.

The Ram 1500 doesn’t stop there, though. In addition to being able to recline the rear seats up to eight degrees and store items under the seat, you’ll also be able to store smaller items in the available in-floor covered storage bins.

The first row of seats also offers an available reconfigurable center console. This massive and customizable console provides enough space to safely and securely store a 15-inch laptop as well as a bin for hanging file folders. Turn the cabin of the Ram 1500 into a mobile office.

Additionally, this console offers storage and charging capabilities for up to five devices. Keep everyone’s phone juiced up for when you arrive at your destination. Long gone are the days of kids fighting over who can charge their phone and for how long.

Spacious Bed Options

Spacious Bed Options & Dimensions

On top of giving you two cab options to choose from, the 2021 Ram 1500 also gives you two bed options to choose from: a 5-foot, 7-inch box and a 6-foot, 4-inch box.

Opting for the 6-foot, 4-inch box will get you a total of 61.5 cubic feet of cargo space to take advantage of in addition to the available RamBox® Cargo Management System.

With this system, you can store all kinds of things in the cargo areas, including tools, athletic equipment, and even ice for cold drinks and food. If your Ram 1500 comes with you to the worksite, securely store your tools with this system, so you have what you need when you need it.

Depending on which bed you decide to go with, the dimensions of the RamBox® on your vehicle will vary slightly. With the 5-foot, 7-inch box, you’ll have around 7.3 cubic feet of cargo space. The RamBox® fitted to a 6-foot, 4-inch box will get you more than 8.6 cubic feet of space.

You’ll be able to stow all kinds of cargo items inside either bed option that the Ram 1500 has to offer. This is thanks to its spacious bed dimensions and 2,320 pounds of maximum payload capacity when properly equipped. The Ram 1500 can haul everything—from 4-wheelers to mounds of fresh mulch for your next DIY landscaping project.

Additionally, the Ram 1500 can be equipped with a multifunction tailgate with re-engineered 60/40 split swing-away doors. Open them up 88 degrees to the left and right for easy access to the bed. This also makes it easy to accommodate extra-long items in the bed, like plywood, for your next home improvement project.

Capable Exterior Dimensions

The exterior size and shape of the 2021 Ram 1500 depends largely on the cab and bed you choose. However, the different options don’t change this model’s commanding and rugged style much. Check out the general exterior dimensions of this model below:

Front / Rear Track Width 68.5 inches / 68.1 inches
Overall Body Height 77.4 inches – 77.6 inches
Overall Body Length 228.9 inches – 241.80 inches
Overall Body Width 82.1 inches
Running Ground Clearance 8.3 inches – 8.4 inches
Wheelbase 140.5 inches – 153.5 inches

The Ram 1500’s impressive design makes it possible for this model to accommodate a large and powerful engine, maximizing your capabilities on and off the worksite.

This model offers an available 5.7L HEMI® V8 engine with eTorque that generates a whopping 395 horsepower and 410 lb-ft of torque. With this kind of power and other optional equipment features, the 2021 Ram 1500 can tow up to 12,750 pounds of trailer weight.

With this kind of towing capacity, you’ll have all kinds of capability at your fingertips. Move the company excavator from one worksite to another or trailer the family fishing boat or camper to the lake for a weekend of solitude. Whatever you choose, you won’t have to worry about making too many stops along the way.

The expansive frame of the Ram 1500 was also designed to accommodate a large 26-gallon fuel tank on the Crew Cab models and a considerable 23-gallon one on the Quad Cab models. With this kind of fuel-carrying capability, you won’t have to interrupt a project or a family road trip with frequent stops at the pump.

Ram 1500 Wheel & Tire Dimensions

The running ground clearance of the 2021 Ram 1500 is approximately 8.3 inches, but this dimension varies drastically, depending on what wheels and tires you choose. Essentially, the larger the wheels and tires, the higher your ground clearance is going to be.

The Ram 1500 provides you with 16 different wheel options in three different sizes: 18 inches, 20 inches, and 22 inches. Standardly, you’ll get 18-inch steel-painted wheels, while the largest option tops out at 22-inch black-painted aluminum wheels.

If you plan to use your Ram 1500 for small jobs and routine commuting to and from work, you’ll want to opt for smaller wheels. You’ll still get nearly 8.3 inches of ground clearance while maintaining good fuel economy—smaller wheels are a bit easier on your fuel consumption.

Those who plan to use the Ram 1500 frequently for off-roading and worksite jobs will want to size up, though. This goes for the tires you choose as well.

You’ll have a variety of tire choices with the Ram 1500. Standardly, the Ram 1500 is equipped with the 275/65R18 BSW All-Season tires, which will get you the standard running ground clearance.

Moving up the tire option rankings, you’ll be greeted by larger, more robust options, like 20-inch OWL All-Season tires, which come with the available Sport Appearance Package of the Laramie trim level.
