When outfitting a 2017 GMC Sierra for work or recreation, understanding the truck bed dimensions is essential for maximizing its capability. The exact length, width, and depth vary depending on the specific configuration, so precise measurements are necessary whether you are hauling lumber, installing a tonneau cover, or simply organizing gear for a weekend trip.
Standard Bed Lengths and Configurations The 2017 GMC Sierra offered three distinct bed lengths to suit different hauling needs, ranging from the maneuverable short box to the lengthy standard box. The standard configuration is the 6.5-foot box, which provides a balance of cargo space and ease of parking. For contractors and DIY enthusiasts requiring maximum capacity, the 8-foot bed was available, offering the longest flatbed area in the segment. Conversely, the 5.3-foot box was designed for drivers who prioritize tight cornering and urban navigation without sacrificing a respectable cargo area. Box Width and Side Rail Details
The 2017 GMC Sierra offered three distinct bed lengths to suit different hauling needs, ranging from the maneuverable short box to the lengthy standard box. The standard configuration is the 6.5-foot box, which provides a balance of cargo space and ease of parking.

Conversely, the 5.3-foot box was designed for drivers who prioritize tight cornering and urban navigation without sacrificing a respectable cargo area.
While the overall length often gets the most attention, the width of the bed walls, or side rails, plays a critical role in actual usability. The 2017 Sierra’s box width is consistent across most trims, measuring approximately 52.5 inches between the inner walls of the side rails. This dimension allows for the safe transport of standard sheets of plywood and building materials without overhanging dangerously. Additionally, the contour of the bed rails is designed to secure tie-downs, ensuring that cargo remains stable during highway transit.
Depth and Vertical Capacity
Vertical space is just as important as horizontal space when calculating volume. The bed depth measures roughly 20.8 inches from the top edge of the box to the lowest point of the floor. This depth is particularly useful for hauling bulky items like tires or large toolboxes, as it provides ample headroom while keeping the load contained. The raised sides also act as a protective barrier, reducing the risk of items shifting or being damaged by road debris.
Impact of Dually Configuration
Owners of the 2017 Sierra equipped with the Dualie configuration, featuring dual rear wheels, will notice a difference in the bed’s internal layout. The presence of the dual wheel wells reduces the available width in the center of the bed, which can affect the transport of wide objects. However, this setup significantly increases the truck’s towing and payload capacity, making it the ideal choice for those who routinely haul heavy trailers or equipment despite the slight compromise in flatbed uniformity.
Measuring for Accessories and Covers
Before purchasing a tonneau cover or side rail management system, accuracy is vital to ensure a proper fit. Generic measurements are often insufficient due to the specific angles and flares of the Sierra’s bed design. Carefully measuring the distance between the front of the bed and the leading edge of the tailgate, as well as the width between the inner rails, will prevent costly returns. Most manufacturers categorize the 2017 Sierra by its box length—5.3, 6.5, or 8 feet—so confirming your specific vehicle is the first step in the accessory buying process.
Payload and Practical Considerations
Ultimately, the dimensions of the bed dictate how you utilize the truck, but the payload capacity determines the limits of that usage. The 2017 Sierra’s engineering ensures that the bed dimensions translate directly into real-world capability, allowing for the transport of heavy machinery or simple household items. By understanding the specific height and length of your box, you can optimize the truck bed to function as a true workhorse, eliminating the guesswork from every haul.
