Is a Lexus LX bigger than a GX?

The Lexus LX is bigger than the GX in most dimensions, reflecting its place in the lineup as a full-size luxury SUV versus the GX’s mid-size footprint. This article compares the current LX 600 and GX models, focusing on exterior measurements and interior space to show how they differ in size and practicality.

Model overview

Both vehicles are three-row, luxury SUVs, but they occupy different segments. The LX is built on a full-size platform and prioritizes expansive interior space and a commanding road presence. The GX sits a notch smaller, offering strong capability in a more compact footprint. Specifications can vary by year and trim, but the general size gap remains consistent.

Exterior dimensions

The following measurements illustrate how the LX generally sits larger than the GX across the key external dimensions.

• Length: LX is typically around 203 inches; GX is around 195 inches. Difference: about 8 inches.


• Wheelbase: LX about 120 inches; GX about 112 inches. Difference: about 8 inches.


• Width: LX roughly 78–79 inches; GX roughly 74–75 inches. Difference: about 4–5 inches.


• Height: LX about 74–75 inches; GX about 72–74 inches. Difference: about 1–2 inches.

Taken together, the LX presents a noticeably larger footprint on the road, with a longer wheelbase and greater overall width and height compared with the GX.

Practical implications of size

The larger exterior translates into more interior space, easier ingress/egress for rear-seat passengers, and greater cargo capacity in most configurations. The GX remains a capable, still-tairy mid-size option for buyers who value a smaller footprint and potentially lower running costs, but it cannot match the LX for maximum space and presence.

Interior space and practicality

Inside, size differences manifest most clearly in passenger comfort and cargo versatility. The LX’s cabin is generally more spacious across all three rows, with more headroom and legroom for rear passengers, and a larger cargo area when the third row is folded or removed. The GX, while still accommodating seven passengers in many trims, offers a tighter third row and comparatively less cargo capacity behind the third row.

• Seating and comfort: LX often provides more generous space in the second and third rows, making it better suited for adult passengers on longer trips. GX remains comfortable but is typically tighter in the third row.


• Cargo capacity: LX usually delivers more storage behind the third row and more overall with the second row folded, whereas GX offers a smaller but practical cargo area for a mid-size luxury SUV.


• Overall cabin feel: Both vehicles deliver premium materials and passenger-focused design, but the LX’s size gives it a roomier, more lounge-like feel in the back rows.

In practical terms, if maximum interior space and cargo flexibility are priorities, the LX is the stronger choice. If a more compact, maneuverable, yet still capable luxury SUV is preferred, the GX remains appealing.

Bottom line: which should you choose?

The decision comes down to space needs versus footprint and everyday usability. For buyers who want the most interior room, a larger sense of luxury, and more cargo ability, the LX is the bigger vehicle. For those who prefer a smaller, more agile daily driver with strong capability and a more compact footprint, the GX offers a solid balance of luxury and practicality.

Summary

In summary, the Lexus LX is bigger than the GX in exterior dimensions and interior space. The LX’s longer length and wheelbase, plus greater width and height, translate to more cabin room and cargo capacity. The GX remains a viable mid-size alternative with a smaller footprint and still-strong luxury features. Your choice depends on whether you prioritize maximum space and presence (LX) or a more compact, nimble luxury SUV (GX).
