Is the Lexus NX or RX bigger?

Yes—the Lexus RX is bigger overall than the NX, especially in exterior length and wheelbase, which typically yields more interior space. This article compares current-generation NX and RX models to give a practical sense of how much bigger the RX is and what it means for daily use.

Exterior dimensions

Length and wheelbase

Length and wheelbase are the most noticeable indicators of size on the road, affecting garage fit, highway stability, and rear-seat space.

NX length: about 183 inches; RX length: roughly 193 inches (RX typically around 10 inches longer).

NX wheelbase: around 104–105 inches; RX wheelbase: about 109–110 inches.

Overall, the RX presents a noticeably longer footprint and a longer wheelbase, which contributes to more interior stretch and a more settled highway ride.

Interior space and practicality

Passenger space

Interior room tends to reflect the exterior footprint. The RX’s larger exterior translates to more rear-seat space and a more accommodating feel for adult passengers, especially on longer trips. The NX remains comfortable in its compact class, but offers less rear legroom and headroom by comparison.

Rear-seat space: RX generally more generous, especially for taller passengers.

Front-seat comfort: both models are comfortable; RX often feels roomier overall due to its size.

For families or frequent rear-seat passengers, the RX's extra length can translate into a more comfortable ride, while the NX remains a strong choice for those prioritizing a smaller footprint and easier urban maneuvering.

Cargo space and versatility

Cargo capacity and loading ease matter for daily use and trips. The RX’s larger body usually affords more flexible storage, though exact figures vary by trim and option packages. Both models offer practical layouts for a compact/midsize crossover, with the RX typically edging out the NX on total cargo volume when seats are down.

Load width and access: RX benefits from a longer rear opening and deeper cargo well, aiding larger items.

Configuration: both offer split-fold seating; RX’s extended footprint provides more usable space in many configurations.

In everyday terms, the RX tends to deliver more usable cargo space and a roomier feel, while the NX shines with its easier-to-park size and adequate cargo for its class.

Which should you consider?

Choosing between the NX and RX comes down to where you place the emphasis—compact footprint and city agility (NX) versus interior comfort and cargo versatility (RX). If you regularly carry adults in the back or need maximum cargo capacity, the RX’s larger dimensions are a clear advantage. If you prioritize nimble city driving and tighter garage spaces, the NX offers strong practicality in a smaller package. Remember that exact measurements can vary slightly by model year, trim, and optional equipment.

Bottom line

Across current-generation models, the Lexus RX is bigger than the NX in exterior dimensions and interior space. The difference is most evident in length and wheelbase, which generally translates to more rear-seat room and greater cargo versatility in the RX. For buyers weighing a compact crossover versus a midsize SUV, size is the primary factor—alongside other considerations like features, price, and driving feel.

Summary

In short, the RX is the larger vehicle compared with the NX. The RX’s longer length and wheelbase offer more interior space and cargo flexibility, while the NX remains a strong, easier-to-maneuver option in the compact crossover segment. Always verify exact figures for the specific model year and trim you’re considering, as small variations can occur.
