Is the Lexus GX or LX bigger?

The Lexus LX is larger than the GX.

The LX is a full-size luxury SUV, while the GX is a mid-size three-row model. That difference shows up in exterior dimensions and interior space, with the LX offering a bigger footprint and more cargo room in most configurations.

Exterior dimensions

To compare exterior size at a glance, these measurements highlight how the two models differ in footprint.

• Overall length: GX ≈ 195–196 inches; LX ≈ 203–207 inches


• Wheelbase: GX ≈ 109.8 inches; LX ≈ 112–114 inches


• Overall height: GX ≈ 68–70 inches; LX ≈ 72–75 inches

In short, the LX sits longer and taller on the road, with a longer wheelbase that contributes to its more spacious stance.

Interior space and cargo

Interior space and cargo capacity reflect the exterior size, affecting seating comfort and practicality.

• Seating configurations: Both models typically offer 7- or 8-seat layouts depending on trim, but the LX often emphasizes a more premium, roomier feel in the second row, while the GX emphasizes versatile seating with robust second-row options


• Cargo behind the third row: LX generally provides more rear cargo space when the third row is in use than the GX


• Maximum cargo with all rows folded: LX offers noticeably more cargo capacity overall, giving it an edge for hauls and gear

Based on these interior metrics, the LX provides more interior volume and practical cargo space, particularly when all rows are folded or when third-row access is in frequent use.

Model-year notes and trim considerations

Model-year changes and trim choices can nudge individual numbers slightly, but the overall order remains the same: LX is the larger vehicle.

• LX generations (notably the 2022–present LX 600) maintain a substantial size advantage over the GX across trims


• GX dimensions have remained relatively stable across recent generations, preserving its mid-size footprint


• Trim packages and seating configurations can affect perceived interior space and seat comfort, but not the broad size hierarchy

For buyers who prioritize maximum interior room or cargo capacity, the LX holds its size advantage across model years and trims.

Bottom line

Overall, the Lexus LX is the bigger vehicle. It is longer, taller, and generally offers more interior and cargo space than the GX, which remains a capable mid-size three-row SUV with strong practicality but a smaller footprint.

Summary

In summary, when choosing between the two, the LX is the larger option with a more expansive exterior and interior footprint, while the GX provides solid three-row utility in a more compact form. For buyers who need maximum cargo and passenger space, the LX is the clear size leader; for those who want a more compact, agile luxury SUV with three rows, the GX remains a compelling choice.
