Given its length of 5857 mm (19.2 feet), width including mirrors at 2032 mm (6.7 feet), and height at 1979 mm (6.5 feet), the Sierra 2500HD Extended Cab Standard Box is quite large. Most standard residential garages are about 6 meters (20 feet) deep and 2.4 to 3 meters (8 to 10 feet) wide, so fitting this truck depends on garage size. While width and height would usually fit comfortably, length could be tight or require a deeper garage space. Owners should measure their garage dimensions to be certain.
The 2011 GMC Sierra 2500HD facelift of the GMT900 generation retains the robust dimensions of the earlier Sierra 2500HD models but with some refined styling and improvements in aerodynamics and interior space. Length and width are similar to the predecessor, maintaining the large footprint necessary for heavy-duty performance. However, enhancements in ride height and ground clearance between 216 to 218 mm (about 8.5 inches) were optimized for better off-road capability compared to older models, alongside updates in curb weight ranging from 2734 to 3252 kg due to added features and structural improvements.
Compared to similar heavy-duty pickup trucks such as the Ford F-250 Super Duty and RAM 2500 of the same era, the 2011 GMC Sierra 2500HD Extended Cab Standard Box is competitively sized. Its length of 5857 mm (19.2 feet) and width of 2032 mm (6.7 feet) are on par, sometimes slightly longer or wider depending on the competitor's specific model and cab configuration. Ground clearance and curb weight also align with industry standards for 3/4 ton pickups, ensuring it performs well in payload, towing, and off-road scenarios. The Sierra's robust build and available equipment options give it strong appeal alongside its rivals.
The Extended Cab Standard Box configuration of the 2011 GMC Sierra 2500HD strikes a balance between passenger accommodation and cargo bed length. It features extra rear-seat space compared to a regular cab, allowing transport of additional passengers or tools securely inside the vehicle, while the standard box offers 6.5 feet (approximately 1981 mm) of bed length, suitable for hauling sizable loads. This setup is ideal for owners requiring a heavy-duty work truck capable of both personnel transport and substantial cargo hauling in a versatile package.

Exterior improvements included a refreshed front grille and lighting design aimed at improving aesthetics and aerodynamics. On the interior, enhancements to materials and ergonomics created a more driver-friendly and comfortable cabin environment.
