Is the Lexus RX 350 big?

Yes. The RX 350 sits squarely in the midsize luxury SUV segment—larger than most compact crossovers but not as big as full-size or three-row giants. For those who want extra seating, the RX 350L adds a third row, but at the cost of some cargo space.


Size and exterior dimensions


Exterior measurements


The current RX 350 is designed to balance urban maneuverability with interior room. Typical figures for the latest model year place its size in the midsize range:



  • Length: roughly 192–195 inches

  • Wheelbase: about 109–110 inches

  • Width: around 74–75 inches

  • Height: about 66–67 inches


These proportions give the RX 350 a substantial road presence while remaining easy to park in city settings. They also help it feel roomy inside without veering into bulky-SUV territory.


Interior space and seating


Seating options


The standard RX 350 is a five-seater, prioritizing comfort and cabin ambiance. A longer-wheelbase variant, the RX 350L, adds a third row for up to seven passengers, expanding versatility but altering rear storage.



  • Five-seat configuration on the standard RX 350

  • RX 350L offers a third row for additional seating capacity

  • Interior materials and refinement are a standout, with generous front-seat comfort


In everyday use, the RX 350 provides ample space for two adults in the back and a comfortable front cockpit. The RX 350L’s third row is best suited for kids or occasional adult travel, with a trade-off in available cargo behind the third row.


Cargo and practicality


Cargo capacity and usability




  • Rear cargo is practical for daily groceries and luggage

  • Folding rear seats expands cargo significantly

  • RX 350L’s third-row setup reduces behind-third-row cargo compared with the standard RX 350


For many families, the standard RX 350 provides a solid balance of passenger space and cargo room. If seven-seat capability is a priority, the RX 350L offers that option, with the understanding that cargo flexibility behind the third row is limited compared with two-row configurations.


RX 350 vs RX 350L: which should you choose?


Assessing the trade-offs


Choosing between the RX 350 and RX 350L comes down to how you value seating versus cargo. The RX 350 is typically more cargo- and comfort-oriented for five passengers, while the RX 350L adds a usable third row for occasional seven-passenger scenarios, at the cost of some trunk space and rear-seat comfort for adults on longer trips.



  • RX 350: excellent five-seat practicality with ample interior space

  • RX 350L: added seating versatility for families that need a 7-seat option

  • Both share Lexus craftsmanship, refined ride, and solid reliability


In short, if you regularly shuttle a full house, the RX 350L is worth considering; if you mostly carry five passengers or want maximum cargo, the standard RX 350 is likely the better fit.


Bottom line


The Lexus RX 350 is a solid, well-rounded midsize luxury SUV that offers a comfortable, upscale experience with a balance of space and maneuverability. It’s big enough for most families and daily use, but not as large as true three-row or full-size SUVs. If you need a third row or more cargo capacity on a regular basis, evaluate the RX 350L alongside its rivals to see which configuration best matches your priorities.


Summary



  • Category: Midsize luxury SUV

  • Standard seating: 5 (RX 350); 7 with RX 350L

  • Key strengths: Ride comfort, refined interior, Lexus reliability

  • Trade-offs: RX 350L adds seating at the expense of rear cargo space

  • Bottom line: A solid, comfortable choice for most families; consider the RX 350L if you need a third row
