RAM Bed Dimensions(Length, Width, Depth & Cargo Specs)

RAM bed dimensions across all models, cab styles, and configurations.Learn precise measurements, cargo capacity details, and how these dimensions affect real-world hauling needs.

Quick Overview

Standard RAM Bed Width Across All Models

All RAM 1500, 2500, and 3500 models share similar bed width measurements. The interior sidewall-to-sidewall width measures approximately 66.4 inches across the entire lineup.

The critical measurement for cargo is the width between wheel wells, which sits around 51 inches. This narrower floor space determines whether items like plywood sheets or ATVs fit flat on the bed floor.

RAM Bed Length Options Explained

RAM trucks offer three primary bed length configurations: the short bed at 5 feet 7 inches, the standard bed at 6 feet 4 inches, and the long bed at 8 feet.

Crew Cab models pair with either 5’7″ or 6’4″ beds. Quad Cab configurations typically come with the 6’4″ bed only. Regular Cab models (found on RAM Classic and heavy-duty variants) offer 6’4″ and 8-foot bed options.

RAM 1500 Bed Dimensions (All Configurations)

RAM 1500 Short Bed (5’7″) Dimensions

The 5’7″ short bed delivers 67.4 inches of interior length from the cab wall to the tailgate. This compact configuration works perfectly for daily driving while maintaining solid cargo capacity.

Total cargo volume reaches 53.9 cubic feet in the short bed setup. The bed depth measures 21.5 inches from floor to top rail, providing plenty of vertical space for gear and equipment.

RAM 1500 Standard Bed (6’4″) Dimensions

The 6’4″ standard bed offers 76.3 inches of interior length, giving you nearly 9 extra inches compared to the short bed. This popular configuration balances maneuverability with hauling capability.

Cargo volume increases to 61.5 cubic feet with the standard bed.

RAM 1500 Long Bed (8′) Dimensions (Classic Models)

The 8-foot long bed provides 96 inches of interior length, offering maximum cargo space for serious hauling needs. This configuration appears primarily on RAM 1500 Classic models and certain fleet variants.

Total cargo volume reaches approximately 77.8 cubic feet in the long bed.

RAM 2500 and 3500 Heavy Duty Bed Dimensions

How RAM HD Bed Sizes Compare to RAM 1500

RAM heavy-duty models maintain similar bed width to the RAM 1500, measuring approximately 66 inches between interior walls. The wheel well spacing also stays consistent at roughly 51 inches.

The key differences appear in frame height and payload capacity, not bed dimensions.

RAM 2500/3500 Bed Length and Width Specifications

RAM 2500 and 3500 models offer 6’4″ and 8-foot bed options. The standard 6’4″ bed provides 76.3 inches of length, while the long bed delivers of cargo space.

Interior width remains at 66.4 inches across both HD bed lengths. Cargo volume matches RAM 1500 specifications, with the 6’4″ bed holding 61.5 cubic feet and the 8-foot bed containing 77.8 cubic feet.

RAM Bed Dimensions by Cab Configuration

Quad Cab Bed Size Options

Quad Cab models pair exclusively with the 6’4″ standard bed on current RAM 1500 trucks.

You get 76.3 inches of bed length with moderate rear seating room. The Quad Cab setup suits buyers who occasionally carry passengers but prioritize hauling capacity.

Crew Cab Bed Pairing and Dimensions

Crew Cab offers the most flexibility with both 5’7″ and 6’4″ bed options.

Choosing the shorter 5’7″ bed keeps overall truck length manageable while maintaining practical cargo space. The 6’4″ bed option with Crew Cab creates a longer vehicle but maximizes both passenger comfort and hauling capability.

Regular Cab Bed Configurations (Classic Models)

Regular Cab models feature the largest bed options at 6’4″ and 8 feet. These configurations appear on RAM 1500 Classic and heavy-duty models, prioritizing cargo space over passenger room.

The 8-foot bed with Regular Cab creates the longest cargo area available in the RAM lineup. Commercial buyers and contractors often choose this setup for maximum material-hauling capacity.

How RAM Bed Dimensions Affect Cargo Capacity

Fitting Standard 4×8 Plywood Sheets

Standard plywood sheets measure 48 inches wide, fitting comfortably between the 51-inch wheel well spacing. You can lay full sheets flat on the bed floor without angling or propping.

For length, you’ll need the tailgate down to accommodate 8-foot sheets. Even the short 5’7″ bed handles full plywood sheets when you secure the front end on the bed floor and let the rear extend over the lowered tailgate.

Loading ATVs and Side-by-Sides

Most standard ATVs range from 42 to 48 inches wide, fitting perfectly between the wheel wells. These recreational vehicles load easily and sit stable on the bed floor.

Larger side-by-sides can exceed 60 inches in width, meaning they must ride on top of the wheel housings rather than between them. Always measure your specific vehicle’s track width before assuming it fits.

Toolbox and Equipment Storage Fit Guide

Crossover toolboxes for full-size RAM trucks are engineered to fit the 66.4-inch bed width, which most aftermarket manufacturers follow as a standard.

Bed-mounted storage systems and cargo slides are compatible across all RAM bed lengths, thanks to the consistent 51-inch wheel well spacing that supports standard and commercial equipment.

Measuring Your RAM Bed Accurately

How to Measure Interior Bed Length

Start at the inside of the tailgate and measure to the front bed wall, keeping your tape measure along the bed floor centerline for accurate length measurement.

Don’t measure from the bumper or exterior body panels; interior cargo space determines if your equipment and materials fit properly.

Measuring Bed Width (Sidewall vs. Wheel Wells)

Measure sidewall width at the top of the bed rails for the full 66.4-inch dimension. This measurement helps when selecting tonneau covers, camper shells, and bed caps.

Drop down to floor level and measure between the wheel housings to find your usable flat cargo width. This narrower measurement (around 51 inches) determines what fits on the bed floor.

Factors That Reduce Usable Bed Space

Spray-in bed liners add approximately 0.25 to 0.5 inches per side, slightly reducing interior width. Drop-in liners can reduce usable space even more due to their formed ribs and raised edges.

RamBox side storage transforms the bed walls into lockable compartments but narrows the main cargo area. Bed racks and rail caps may also affect how items sit on top of the wheel housings.
