Both the TX and LX have the same width – 78.3 inches. However, the LX offers more hip room – 59.6 inches in the front, 58.8 inches in the middle, and 49 inches in the third row.
Unlike its full-size sibling, which is consistently a six- or seven-seater, this model has two-row options. The Ultra seats four, forgoing a traditional second-row bench seat for dual captain's chairs.

What Are Your Lexus Midsize Options?
2025 Lexus GX
Full-size SUVs are incredible for cargo capacity, but you don't need the Lexus biggest SUV to feel comfortable or have room for your gear. Especially for people who drive in the city, having a little less length can help you to stay maneuverable.
The Lexus GX is a midsize option that is comparable to the largest Lexus SUV. With 37.89 inches of third-row legroom, adults will have more opportunity to stretch out than they would in the comparable seats in either the Lexus TX or Lexus LX. You can also choose to get this model as a two-row vehicle, which will expand your maximum cargo capacity from 76.9 cubic feet to 90.5 cubic feet behind the front row.
Some drivers also compare the Lexus GX to the Toyota 4Runner. See our Lexus GX vs. Toyota 4Runner comparison to learn why Lexus leads with luxury, technology, and comfort while still offering rugged capability.
