Exterior and overall size

Understanding the size difference starts with the exterior footprint. The LX is designed to be noticeably longer and taller, with a longer wheelbase that translates to more interior space and a more commanding road presence.

Dimensions at a glance

These figures illustrate the size difference in basic terms. Note that exact numbers vary slightly by model year and trim, but the LX generally measures longer and rides on a longer wheelbase than the GX.

What to expect in everyday use

For families or buyers who need maximum passenger room and cargo flexibility, the LX's larger footprint tends to matter more than in the GX, which remains a capable but smaller three-row option in the Lexus lineup.

Cargo behind third row: LX generally offers more usable space behind the third row than the GX.

Typical use case: LX is favored for full-size SUV duties, including towing and long trips; GX suits mid-size SUV needs with strong off-road chops and luxury features.

Bottom line: If overall size and maximum interior space are your priorities, the Lexus LX is the bigger model.

Bottom line and takeaway

Across exterior dimensions and practical interior space, the Lexus LX outpaces the GX. The LX’s bigger footprint translates into more cargo capacity and passenger comfort, while the GX remains a solid, smaller alternative within Lexus’s SUV range.

Summary: The Lexus LX is larger than the GX in exterior footprint, wheelbase, and interior space. For buyers who prioritize maximum room and a full-size SUV experience, the LX is the bigger option; the GX offers a more compact, still-capable choice with many luxury features.
