With a width of 1880 mm (74.0 inches), the Acura RDX III offers a spacious interior but remains reasonably sized for maneuverability. The width allows for comfortable seating and shoulder room inside, while also being narrow enough to navigate most urban parking spaces and street lanes without excessive difficulty.

The Acura RDX III, measuring 4747 mm (187 inches) long, 1880 mm (74.0 inches) wide, and 1669 mm (65.7 inches) tall, generally fits well in a standard residential garage. Most single-car garages are typically 2.4 to 2.7 meters wide (about 8 to 9 feet) and over 5 meters (16.5 feet) deep, so this SUV’s dimensions should allow for comfortable parking with some room for door opening.

The third-generation Acura RDX (2019-2021) is notably larger than the second-generation model. It grew in length and width to provide increased passenger room and cargo capacity. Specifically, the RDX III’s length of 4747 mm (187 inches) and width of 1880 mm (74 inches) represent an increase over the prior generation, translating to a more spacious and comfortable cabin environment, better accommodating families and gear.

Compared to other mid-size luxury SUVs like the BMW X3 or Audi Q5, the Acura RDX III exhibits a competitive size profile. Its 4747 mm (187 inches) length and 1880 mm (74 inches) width place it slightly on the larger side in this segment, offering more interior cargo space with its 835 liters (29.5 cubic feet) luggage capacity. While similar in footprint, the RDX often optimizes space efficiently to stand out in family-friendly usability and cabin room.

The Acura RDX III’s height is 1669 mm (65.7 inches), which provides an elevated driving position typical of SUVs, enhancing visibility on the road.

Classified as a compact luxury SUV, the Acura RDX III balances size and functionality. Its dimensions support agile handling in city environments, while the SUV body style ensures higher ride height and more cargo space than typical sedans. This classification favors consumers seeking a blend of everyday usability, passenger comfort, and occasional off-road or rough weather capability.
