What is the difference between a GMC short box and a standard box?

In short, the GMC short box is a shorter cargo bed configuration (roughly 5 ft 8 in) that yields a shorter overall vehicle length, while the standard box uses a longer bed (roughly 6 ft 6 in). Exact numbers vary by model and year.

The difference matters for cargo length, daily maneuverability, and which GMC model offers each bed size. This article breaks down the distinctions and how they affect real-world use for GMC trucks such as the Sierra 1500 and Canyon.

Bed lengths and configurations

Before listing typical lengths, note that GMC offers several bed options and availability varies by model and cab setup. Use these figures as a guide and verify current specs with a dealer.

• Short box: about 5 feet 8 inches (68 inches) of cargo bed space.


• Standard box: about 6 feet 6 inches (78 inches) of cargo bed space.


• Long box: about 8 feet (96 inches) for certain configurations; not all trims offer this option.

In practice, most Crew Cab versions pair with either the short box or the standard box, while the long box is typically found on specific configurations and some Regular Cab layouts. The bed length chosen can influence overall vehicle length and wheelbase.

Practical differences for daily use

How the bed length translates to everyday use includes cargo capacity, payload handling, towing dynamics, and parking/manoeuvrability. Here are the core effects to consider before choosing a GMC box length.

• Cargo space and item fit: Short boxes limit the length of long items (lumber, pipes, furniture), but still offer close to full truck-bed utility for most daily tasks.


• Overall size and turning/maneuverability: Short boxes yield a shorter overall vehicle length, making parking and city driving easier; standard/long boxes make the truck longer to park and maneuver.


• Payload and weight distribution: Box length does not dramatically change the Gross Vehicle Weight Rating, but wheelbase and weight distribution can influence handling when loaded.


• Availability by model: Not every Sierra 1500 or Canyon trim offers every bed length; check the current lineup to see which bed lengths are compatible with your preferred cab configuration.

Bottom line: The choice comes down to how you intend to use the truck—whether cargo length or daily drivability is your priority—and which GMC model and cab configuration you prefer.

Choosing between short box and standard box

For buyers who frequently haul long items or need more bed space for tools, a standard box is typically the better fit. If you value a tighter turning radius, easier parking, and a lighter overall footprint for city driving, the short box is often more convenient. Consider your typical loads, the cab style you want, and consult current GMC specs to confirm availability on the model you’re eyeing.

Summary

The difference between a GMC short box and a standard box is primarily bed length: roughly 5'8" for the short box versus about 6'6" for the standard box, with longer 8' options available on select configurations. This distinction affects cargo capabilities, overall vehicle length, and ease of maneuvering. Your choice should align with your cargo needs, daily driving context, and the GMC model lineup you’re considering.

What is the difference between GMC standard box and short box?

The main differences are bed length, maneuverability, and cargo volume: a short box is more maneuverable, while a standard box offers more cargo space and stability for towing. GMC short boxes are 69.9 inches, providing 62.9 cubic feet of cargo volume and making them easier to park. GMC standard boxes are 79.4 inches, offering 71.7 cubic feet of volume and better stability for towing due to the longer wheelbase.

Short Box

• Length: 69.9 inches (approximately 5.8 feet) 
• Cargo Volume: 62.9 cubic feet 
• Pros: Better for city driving and navigating tight spaces due to the shorter overall length and smaller turning radius. 
• Cons: Less cargo space and less stability for towing larger loads or fifth-wheel trailers. 

Standard Box

• Length: 79.4 inches (approximately 6.6 feet)
• Cargo Volume: 71.7 cubic feet
• Pros: More space for hauling gear and greater stability when towing due to the longer wheelbase.
• Cons: More difficult to maneuver and park, especially in tight spots.

Which should you choose?

• Choose a short box if you prioritize parking and maneuverability, and don't frequently carry large or heavy loads. 
• Choose a standard box if you need the extra cargo space for work or hauling and are looking for improved stability when towing. 

What is a GMC standard box?

The GMC Sierra bed sizes (AKA “box” sizes) are as follows for the 1500 model for the 2022 model year: GMC Sierra 1500 Crew Cab – Available on SLE, Elevation, SLT, AT4, and Denali Models. Short Box: 69.9 inches. Standard Box: 79.4 inches.

What is the difference between a short bed and a standard bed truck?

The standard bed of a pickup truck is typically 6'5" long, nine inches longer than the conventional short bed. Even though it might not seem like much at first, it can make a significant difference if you need to move large objects like furniture.

What are the advantages of a short bed truck?

Short beds are great for truck owners who live in urban areas. Their smaller size means they're easier to navigate through narrow city streets with lots of traffic. Short beds are also a good choice for pickup drivers who don't need a ton of cargo space, as they offer less capacity than other styles.
