Which is bigger, the Lexus UX or the NX?

The Lexus NX is larger than the Lexus UX. In short, the NX boasts a bigger exterior footprint and more interior space, while the UX remains the smaller, more city-friendly option.


The question compares which model is bigger in terms of exterior size and inside volume. It’s a comparison that typically covers exterior dimensions (length, width, height, wheelbase) as well as cabin and cargo space for the two crossovers. Here is a clear rundown based on current 2024–2025 model details.


Exterior footprint


Key exterior measurements you should compare include length, width, height, and wheelbase. The numbers below reflect typical figures for standard trims with common wheel options.



  • Length: UX is around 177–178 inches; NX is around 182–183 inches.

  • Width (excluding mirrors): UX about 72.4 inches; NX about 74–75 inches.

  • Height: UX around 60.5–60.6 inches; NX around 64–65 inches.

  • Wheelbase: UX about 103.9 inches; NX about 104.7 inches.


Taken together, these exterior measurements show the NX is longer, wider and taller than the UX, giving it a noticeably larger footprint on the road.


Interior space and cargo


Inside, the NX generally offers more passenger room and a larger cargo area, while the UX cabin emphasizes compactness and ease of maneuvering. The following points highlight where the NX wins on space.



  • Passenger space: NX tends to provide more rear legroom and overall cabin width; the UX cabin is tighter, especially for adults in the back seat.

  • Cargo space: UX typically offers mid-teens to low-20s cubic feet behind the rear seats, while NX provides more behind-rear-seat cargo capacity and greater total cargo flexibility, depending on trim and seating configuration.


In practical terms, the NX delivers more interior space and cargo capacity on average, while the UX prioritizes a smaller footprint with efficient packaging and city-friendly proportions.


Summary: When deciding between the two, the NX is the bigger option overall. It has a larger exterior footprint and more interior/cargo space. The UX remains appealing for buyers who value a more compact, nimble crossover with efficient use of interior space.
