How big is the bed of an Avalanche?
The Chevrolet Avalanche is a unique blend of SUV and pickup built from 2002 to 2013. Its cargo bed behind the cabin runs 5 feet 9 inches, and its standout Midgate feature lets you extend the bed to about 8 feet when you fold the rear wall into the cab and lower the tailgate.
Bed dimensions and extension
Two core measurements describe the Avalanche's cargo space: the standard bed length behind the cab, and the maximum length achievable with the Midgate system. The list below captures these figures for typical configurations.
- Standard cargo bed length behind the cab: 69 inches (5 feet 9 inches).
- Maximum extended bed length with Midgate and tailgate down: about 96 inches (8 feet).
In practical terms, this means you can carry longer items—such as lumber or appliances—by using the Midgate extension, something many pickups can't do without removing seats or reconfiguring cargo space.
Model-year notes
For most model years (2002–2013), the standard bed length remained the same, and the Midgate extension provided the same maximum length. The design and features are a defining trait of the Avalanche compared to conventional pickups.
How the Midgate extension works
Understanding what makes the Avalanche's bed so flexible hinges on the Midgate. This panel collapses the rear wall of the cab into the cargo area, effectively lengthening the bed. When paired with a lowered tailgate, the system allows a continuous floor from the cab to the tailgate for longer payloads.
- The Midgate folds the rear wall down into the cargo area to extend load length beyond the standard bed.
- The tailgate can be lowered to create a longer continuous cargo floor, enabling even longer items.
- The maximum extended length with both Midgate and tailgate down is about 96 inches (8 feet).
That combination of features was the Avalanche's distinctive answer to the need for both passenger space and cargo flexibility in a single vehicle.
Summary
The bed behind the Avalanche's cabin measures 69 inches long, and thanks to the Midgate system, you can extend it to about 96 inches for longer loads. The feature set, available during the model years from 2002 to 2013, remains its defining characteristic.
How big is the bed on a 2011 Avalanche?
One of the 2011 Chevrolet Avalanche's standout features is its versatile cargo space. The 5.3-foot truck bed offers ample room for smaller cargo, but the midgate system allows the rear seats to fold down, expanding the bed to 8.2 feet.
How big is the bed on a 2008 Avalanche?
The Avalanche's bed measures 5.3 feet long and has 45.5 cubic feet of volume — roughly equal to a four-door Dodge Dakota Club Cab. Second-row seats fold inward with the midgate to extend the cargo bed 35 inches, which puts total length on par with a long-bed Ford F-150.
How big is an Avalanche bed?
The Chevy Avalanche bed size is about 5.3 feet (or 63 inches) with the midgate up and rear seats in place. It can be extended to approximately 8.2 feet by lowering the midgate, which allows the rear window and seats to fold down to connect with the cabin.
- Standard size: Around 5.3 feet (63 inches) with the midgate in its upright position.
- Extended size: Approximately 8.2 feet (8.1 inches) when the midgate is lowered to connect with the cabin, which accommodates longer items.
- Key feature: The Avalanche's "Midgate" allows the rear seats and window to fold down, creating a much larger, open cargo area.
What size box is the Chevy Avalanche?
8.1 ft.
Avalanche has 8.1 ft. of cargo box length — enough to transport a small kayak. (Chevy Avalanche shown with rear window stowed, Midgate lowered and cargo cover removed.)
