The 2019 Ford F-250 Super Duty is available with two primary cargo box configurations: the 6.75-foot "standard" bed and the 8-foot "long" bed. The specific dimensions depend on the cab configuration, as the short bed is typically paired with SuperCab or Crew Cab models, while the long bed is commonly found on Regular Cab, SuperCab, or Crew Cab variants.
The Super Duty series represents the heavy-duty tier of Ford's truck lineup, and understanding the exact dimensions of the cargo box is essential for owners who need to transport specialized equipment, haul construction materials, or install aftermarket accessories like tonneau covers, fifth-wheel hitches, or slide-in campers. Because the F-250 is often used as a work vehicle, these measurements serve as the baseline for determining payload compatibility and logistical planning.
Understanding the 2019 F-250 Bed Configurations
Ford standardized the bed sizes for the 2019 model year across the Super Duty platform, including the F-250, F-350, and F-450. There are essentially two "lengths" in the eyes of the consumer, but the internal physical dimensions remain consistent regardless of the trim level (XL, XLT, Lariat, King Ranch, Platinum, or Limited).
The 6.75-Foot Bed (Standard Bed)
The 6.75-foot bed is the most common configuration for retail buyers, particularly those opting for the Crew Cab. It provides a balance between interior passenger comfort and exterior utility. While it is often called a "short bed," it remains significantly deeper and wider than the beds found on many light-duty trucks, making it highly capable for general hauling and recreational towing.
The 8-Foot Bed (Long Bed)
The 8-foot bed is the industry standard for professional-grade work. It is required for owners who frequently transport full-size sheets of plywood or drywall flat against the floor, as well as for those who need the extra length for large-scale livestock trailers or heavy industrial machinery. When paired with the Regular Cab, the truck achieves maximum maneuverability while retaining the longest possible cargo deck.
Technical Dimensions and Internal Measurements
To make informed decisions regarding cargo and accessories, you must rely on the precise measurements of the bed. The following data highlights the interior dimensions that dictate what you can actually fit inside the box.
| Feature | 6.75-Foot Bed (Short) | 8-Foot Bed (Long) |
|---|---|---|
| Length at Floor | 81.9 inches | 98.4 inches |
| Width at Floor | 66.9 inches | 66.9 inches |
| Width between Wheelhouses | 50.5 inches | 50.5 inches |
| Depth (Inside) | 21.1 inches | 21.1 inches |
| Tailgate Opening Width | 60.5 inches | 60.5 inches |
Note: All measurements are based on official specifications provided for the 2019 model year. Slight variations may exist based on optional bed liners or aftermarket modifications.
Key Architectural Constraints
The Wheelhouse Barrier
The "width between wheelhouses" is perhaps the most critical dimension for contractors and hobbyists. At 50.5 inches, this width allows for a standard 48-inch sheet of building material (such as plywood or drywall) to sit perfectly flat on the floor of the bed. This is a deliberate design choice by Ford to ensure the F-250 remains a functional tool for construction environments. If you are planning to load materials wider than 50 inches, you will need to rely on wheel-well covers or create a raised platform, which effectively reduces the depth of your usable space.
Depth and Volume
With an internal depth of 21.1 inches, the 2019 F-250 bed provides significant vertical volume. This depth is beneficial for securing large items using ratchet straps or load bars. However, it also means that accessing items near the cab from the side of the truck can be difficult for individuals of average height, necessitating the use of step-sides or the integrated tailgate step offered as an optional feature on many 2019 trims.
Practical Considerations for Owners
Compatibility with Tonneau Covers and Caps
When purchasing a tonneau cover or a camper shell for a 2019 F-250, you must know your specific bed length. Manufacturers categorize these accessories strictly by bed size. A cover designed for the 6.75-foot bed will not fit the 8-foot bed, and vice versa. Always verify the "model year" and "bed length" in your accessory manufacturer's fitment guide, as the 2019 body style aligns with the 2017–2022 Super Duty generation.
Fifth-Wheel and Gooseneck Towing
The F-250 is frequently used for towing. If you intend to use a fifth-wheel hitch, the bed length directly impacts your ability to turn. A long-bed truck (8-foot) generally allows for a standard fifth-wheel hitch because there is enough clearance to prevent the trailer from hitting the cab during tight turns. If you are using a short-bed (6.75-foot) truck, you will almost certainly require a sliding hitch or an extended pin box to prevent cab contact during maneuvering.
Payload and Center of Gravity
While the dimensions dictate volume, payload capacity dictates mass. Even if a specific item fits within the 8-foot bed's dimensions, you must ensure that the weight of that cargo does not exceed the truck’s GVWR (Gross Vehicle Weight Rating). Loading the bed heavily—especially with a slide-in camper—shifts the vehicle's center of gravity. Ensure your specific F-250 trim is rated for the load you intend to place in the bed.
Frequently Asked Questions
Does the 2019 F-250 bed width change based on the trim level? No. All 2019 F-250 models use the same structural box design regardless of trim. Whether you have an entry-level XL or a high-end Limited, the width between the wheelhouses and the overall bed depth remain identical.
Can I fit an ATV or UTV in the 6.75-foot bed? Many ATVs will fit into the 6.75-foot bed with the tailgate down. However, the length of your specific machine is the deciding factor. Always measure from the front tire to the rear tire and compare it to the 81.9-inch floor length. If the ATV is longer than the bed, you must leave the tailgate down and use appropriate safety flags and securement points.
Are the mounting points for accessories the same for all 2019 beds? Yes. Ford uses standardized mounting locations for the BoxLink system and factory tie-downs. If you are adding aftermarket lighting, bed extenders, or storage racks, these mounting points are consistent across both the 6.75-foot and 8-foot configurations.
Does a bed liner change the interior dimensions? A factory drop-in liner or an aftermarket plastic liner will slightly reduce the interior dimensions by approximately 0.5 to 1 inch. If you are measuring for a very tight fit, such as a custom-built box or specialized equipment, account for the thickness of the liner. Spray-in liners typically have a negligible impact on overall dimensions.
What is the most effective way to measure my bed? To get the most accurate reading, use a steel tape measure. Start from the inside of the tailgate and pull the tape to the bulkhead (the wall closest to the cab). Ensure you are measuring at the floor level, as the top rails may be slightly wider or narrower due to the bed's taper.
Recommendations for Success
If you are planning to use your 2019 Ford F-250 for heavy construction, farming, or full-time RV towing, the 8-foot bed is the superior choice for logistical flexibility. The ease of loading standard-sized materials and the additional clearance for heavy trailers provide a clear operational advantage. If your truck serves primarily as a personal vehicle that occasionally hauls recreational gear, the 6.75-foot bed provides a more manageable turning radius and easier parking without sacrificing the essential depth required for serious work. Always verify your specific VIN or door jamb sticker for exact payload capacities to ensure that your loading plan aligns with the truck's mechanical limits.
