Lexus SUV size guide

Lexus SUV sizes

The arrival of the all-new Lexus LBX in March 2024 means that Lexus will have expanded its range of petrol-electric hybrid and battery electric SUVs to five distinct models: LBX, UX, NX, RX and RZ. Read on below for our Lexus SUV size guide.

Each model is identified by a descriptive, two- or three-letter acronym – for example, UX is a stylised contraction of Urban Crossover. However, these acronyms do not necessarily offer an immediate indication of the relative size of each model. But we realise that understanding their proportions is vital in determining which Lexus SUV is the best possible fit for your needs and lifestyle… or even your garage.

We therefore hope that the following Lexus SUV sizes table is helpful in illustrating the comparative dimensions of each model.

Lexus SUV sizes:

LBX 4190mm 1825mm 1560mm 2580mm 317 to 994 litres
UX 4495mm 1840mm 1540mm 2640mm 283 to 1231 litres
NX 4660mm 1865mm 1670mm 2690mm 521 to 1436 litres 
RZ 4805mm 1895mm 1635mm 2850mm 522 to 1451 litres 
RX4890mm 1920mm 1695mm 2850mm 461 to 612 litres 

The Lexus LBX is positioned as the smallest model in our crossover range. It is more compact than the UX, which in turn is smaller than the mid-size NX. Our largest SUV is the full-size RX, while straddling the space between mid-size and full-size is the RZ. Thanks to this model’s EV-specific architecture, it has the same wheelbase as the RX and a lower height than both the NX and RX.

The hierarchy of self-charging hybrid powertrains is reflective of each model’s relative size. The Lexus LBX is equipped with a 1.5-litre three-cylinder petrol engine, while the UX is equipped with a 2.0-litre four-cylinder petrol engine. All Lexus NX models and the majority of RX models are equipped with a 2.5-litre four-cylinder petrol engine (2.4-litre turbo in the RX 500h).

Similarly, the all-electric UX 300e is equipped with a 54.35 kWh battery and 201bhp motor, while the larger RZ 450e is equipped with a 71 kWh battery and motors that can deliver 309bhp combined.


  1. Really hoping the RZ has interior room equal to or greater than the RX as I plan to trade my LS 460 for the electric RZ in 2024

  2. When is the new RX being launched in the UK and do you have any information on its specification

    1. Hello David,
      We do not have any information on this at the moment.
      Please keep an eye on our blog and social media channels for the latest information.

  3. How does the UX compare in dimensions to the CT200H especially the boot size? When are prices due?

    1. Hello Bryan,
      Thanks for your comment.
      The UX 250h has approximately a 25l larger boot than the CT.

    1. Hello Tim,
      Thanks for your comment. The estimated ETAs are as follows:
      NX Hybrid – Q3 2023.
      NX Plug-in – January 2023.
      RX – October 2022.
      RZ – Not available at this time.
      We hope this helps.

  4. Are the widths above excluding wing mirrors? If so, do you have the widths including them, as that makes it much easier to compare to my current car.

    1. Hello Andrew, thanks for your comment.

      This size guide includes the wing mirrors in the measurements.
