What are the interior dimensions of the Ram 1500?
The Ram 1500's interior dimensions vary by cab style (Regular, Quad Cab, Crew Cab), bed length, year, and trim. In practice, the Crew Cab with a 5'7" bed is the most common configuration and offers the most cabin space. Exact figures should be checked in the official Ram brochure for your model year.
How Ram defines interior space
Ram reports interior room primarily in terms of headroom, legroom, shoulder room, and hip room for both the front and rear seating rows. The numbers vary modestly with seat position, trim, and option packages that affect seat cushions and cabin structure.
Crew Cab (most common, 5'7" bed)
Before listing the dimensions, note that these figures come from typical Ram 1500 specifications for Crew Cab models during recent years and may vary by year and trim.
- Front headroom: about 40.0 to 40.3 inches
- Front legroom: about 40.8 to 41.0 inches
- Front shoulder room: about 65.6 to 66.0 inches
- Front hip room: about 58.0 inches
- Rear headroom: about 39.5 to 40.0 inches
- Rear legroom: about 40.0 to 40.9 inches
- Rear shoulder room: about 63.5 to 65.0 inches
- Rear hip room: about 57.0 to 58.0 inches
Crews Cab configurations offer a spacious second row with ample shoulder and hip room, while maintaining generous front room for the driver and front passenger.
Quad Cab
Before listing the dimensions, note that Quad Cab is a four-door configuration with a smaller rear seating area compared to Crew Cab. The figures below reflect typical ranges for recent Quad Cabs with a 5'7" bed.
- Front headroom: about 40.0 to 40.3 inches
- Front legroom: about 40.0 to 40.6 inches
- Front shoulder room: about 65.0 to 66.0 inches
- Front hip room: about 58.0 inches
- Rear headroom: about 38.5 to 39.5 inches
- Rear legroom: about 38.0 to 39.3 inches
- Rear shoulder room: about 62.0 to 63.5 inches
- Rear hip room: about 55.5 to 57.0 inches
Quad Cab configurations strike a balance between rear-seat space and cargo-bed accessibility, often appealing to buyers who need occasional rear seating without sacrificing bed length.
Regular Cab
Before listing the dimensions, note that Regular Cab variants have two doors and a two-seat or basic seating arrangement with no rear seat in most cases. The interior dimensions below focus on the front cabin.
- Front headroom: about 40.0 to 40.5 inches
- Front legroom: about 40.0 to 41.0 inches
- Front shoulder room: about 63.0 to 66.0 inches
- Front hip room: about 55.0 to 58.0 inches
- Rear seating and rear interior dimensions are not applicable in a standard Regular Cab Ram 1500
Regular Cab variants prioritize cargo space and efficiency, with minimal rear seating options.
Where to find exact numbers for your model year
Because interior dimensions change with one-year updates, trims, and seat configurations, consult the official Ram 1500 brochure or the Ram Trucks website for your exact year. You can also measure the interior yourself or compare with dealership spec sheets for the precise figures relevant to your vehicle.
Summary
The Ram 1500 offers a range of interior dimensions that depend on cab style and bed length. Crew Cab configurations provide the most space, with generous front and rear headroom, legroom, shoulder, and hip room. Quad Cab sits between Crew and Regular Cab in rear space, while Regular Cab prioritizes cargo space and efficiency over rear-seat comfort. For the most accurate numbers, check the specific year’s Ram brochure or factory specs.
