Whether you’re hauling a full carpool or packing for a weekend at the Delaware beaches, the Acadia is designed to fit your life. Explore the key dimensions below, then visit Kent County Motors in Dover to experience this spacious cabin in person.

The 2026 GMC Acadia interior is a sanctuary of space. Unlike many midsize competitors, the Acadia features a “true” adult-friendly third row, ensuring that even your tallest passengers stay comfortable on long trips past Middletown. Depending on your choice of second-row bench seating or captain’s chairs, the Acadia comfortably accommodates 7 to 8 passengers.

2026 GMC Acadia Exterior Dimensions: The “Garage Check”

While the Acadia has grown in size to maximize interior comfort, GMC engineers kept the footprint manageable for Dover drivers. At roughly 17 feet long, the Acadia is designed to fit into most standard residential garages around Smyrna while providing a commanding view of the road.

Exterior Dimension Measurement
Overall Length 204.0 inches
Width (Without Mirrors) 79.6 inches
Overall Height 71.0 – 72.0 inches
Wheelbase 120.9 inches
Ground Clearance (Min) 6.8 – 7.8 inches

*Note: Exterior height and ground clearance vary by trim level. The off-road-ready Acadia AT4 features a lifted ride height and a wider track for enhanced stability on rugged terrain.
