What is bigger, Lexus RX or UX?
The Lexus RX is bigger than the Lexus UX in most dimensions, including exterior length and wheelbase, with more interior space overall. The UX remains the smaller, city-friendly crossover.
Both models come from Lexus’ SUV lineup but target different buyers: the RX sits in the mid-size category and offers more room, while the UX is a subcompact crossover designed for maneuverability and efficiency. The comparison below focuses on current-generation models (as of 2024–2025) to illustrate how size differentiates the two.
Size and dimensions
The following figures summarize key exterior measurements for the latest UX and RX models. Where applicable, note that the RX L is the extended-length variant offering extra interior space.
- Length: UX is about 178 inches; RX is about 192–196 inches. The RX L adds even more length beyond the standard RX.
- Wheelbase: UX sits around 104 inches; RX runs roughly 110 inches, with the RX L sharing a longer stance similar to its length.
- Width: UX is about 72.4 inches wide; RX is roughly 74.6 inches wide, contributing to a larger overall footprint.
Overall, the RX lineup presents a noticeably larger exterior footprint than the UX, with the extended RX L variant further amplifying interior opportunities and presence on the road.
What drives the size difference
The RX’s longer length and wheelbase translate to more rear-seat space and cargo-carrying ability, while the UX emphasizes a compact, nimble feel suitable for urban driving. The RX L variant adds even more interior volume, including an optional third row in some configurations.
Interior space and seating
The two vehicles differ in seating configurations and cabin practicality. The UX and RX both offer five-seat layouts by default, but the RX family adds a larger option set with the RX L’s seven-passenger potential.
Below is a quick look at seating and cabin practicality to help compare everyday usability.
- Seating capacity: UX standard 5; RX standard 5; RX L offers up to 7 passengers with an optional third row.
- Rear passenger space: The RX generally provides more rear-seat legroom and overall cabin volume due to its longer body; the UX remains comfortable for city trips but is more compact behind the second row.
- Cargo and storage: With typical seating for five, the RX’s larger footprint yields more overall cargo capacity in many configurations, while the UX prioritizes compact practicality and easier loading in tighter spaces.
Conclusion: If you need extra passenger capacity or more cargo flexibility, especially with occasional seven-passenger seating, the RX (and RX L) is the stronger option. If you value a smaller footprint with easier parking and urban maneuverability, the UX is the more practical pick.
Bottom line for buyers
The size gap between the RX and UX is substantial in terms of exterior dimensions and interior potential. Choose the RX if you want more space, comfort on longer trips, and, in the RX L, the option of seven seats. Choose the UX if you prioritize a smaller footprint, tighter turning radius, and efficiency for city driving.
Summary
In short, the Lexus RX is bigger than the UX across key measurements, with longer length, a longer wheelbase, and more interior space—especially in the extended RX L variant. The UX remains the compact option, better suited for urban driving and tighter spaces. For those weighing space versus nimbleness, size largely tips in favor of the RX for most practical uses.

Is the Lexus UX being discontinued?
Yes, the Lexus UX is being discontinued, with production for the hybrid and electric versions scheduled to end in late 2025. This is part of a broader phase-out of the UX line, with various models being retired over the next year or so.
- Production end: Production for both the gas/hybrid and fully electric (UX 300e) models is scheduled to end by November 2025.
- Replacement: In some markets, the smaller Lexus LBX is being introduced to replace the UX, while the larger RZ450e is expected to take over as the primary all-electric option in others.
- Reasoning: Reports suggest the decision is due to lower-than-expected sales and the introduction of the new, smaller LBX model.
