Lexus RX 350 Dimensions: Length, Width, Height & Ground Clearance

The Lexus RX 350 is a midsize luxury SUV, but its size has changed noticeably across generations. Newer models are wider and have a longer wheelbase than earlier RX 350s, which affects parking, garage fit, passenger space, and everyday practicality.

For 2026, the Lexus RX 350 measures approximately 192.5 inches (4,890 mm) long, 75.6 inches (1,920 mm) wide, and 67.3 inches (1,710 mm) high. Its wheelbase measures 112.2 inches (2,850 mm).

The current RX 350 also provides about 29.6 cubic feet of cargo space behind the rear seats and up to 46.2 cubic feet with the rear seating area configured for maximum cargo capacity, according to Lexus specifications.

This guide breaks down the Lexus RX 350 dimensions by generation and explains what those numbers actually mean for parking, passengers, luggage, and garage space.

Lexus RX 350 Dimensions at a Glance

Here is a quick comparison of representative RX 350 model years.

For shoppers comparing the Lexus RX 350 length and width, the 2026 model measures 192.5 inches long and 75.6 inches wide. That equals approximately 16 feet long and 6.3 feet wide, excluding the side mirrors. These measurements are useful when checking garage space, parking clearance, or comparing the RX 350 with another midsize SUV.

2026 Lexus RX 350 Dimensions in Inches

The 2026 Lexus RX 350 measures 192.5 inches long, 75.6 inches wide with the mirrors folded, and 67.3 inches high, with a 112.2-inch wheelbase.

• Length: 192.5 inches

• Width: 75.6 inches

• Height: 67.3 inches

• Wheelbase: 112.2 inches

How Long Is the Lexus RX 350 in Feet and Inches?

The 2026 Lexus RX 350 is 192.5 inches long, or approximately 16.04 feet.

Earlier RX 350 models were shorter, with the 2008 model measuring about 186.2 inches. The RX grew significantly with later generations, reaching roughly its current overall length by 2016.

How Wide Is the Lexus RX 350?

The 2026 Lexus RX 350 is approximately 75.6 inches (1,920 mm) wide.

Width has also increased over time. Compared with the 2008 RX 350, which measured about 72.6 inches wide, the current model is roughly 3 inches wider.

Lexus RX 350 Height

The 2026 Lexus RX 350 is approximately 67.3 inches (1,710 mm) high.

Height has remained relatively consistent compared with length and width.

This is important because published height can vary depending on equipment. Roof rails, wheel-and-tire combinations, suspension setup, and measurement methods can create small differences.

If you have low garage-door hardware or another height restriction, measure the exact vehicle rather than relying only on a general RX 350 figure.

Lexus RX 350 Seat Height From the Ground

Lexus does not publish a fixed RX 350 seat height from the ground as a standard vehicle dimension. The driver's seat is adjustable, so the exact ground-to-seat distance changes according to the selected seat position.

For buyers researching seat height because of entry and exit comfort, the RX 350 provides an SUV-style seating position rather than the lower seating position found in a sedan. Lexus specifically designs the current RX front seats with accessibility and ergonomic comfort in mind.

If an exact seat-to-ground measurement is important for mobility or accessibility, measure the specific RX 350 with the driver's seat adjusted to the preferred driving position.

Lexus RX 350 Wheelbase

Wheelbase is the distance between the front and rear axles. It is one of the most useful measurements for understanding how a vehicle's exterior size relates to its interior.

The current RX therefore has a wheelbase more than 5 inches longer than the 2008 model.

The interesting comparison is between 2016 and 2026. Both vehicles are roughly 192.5 inches long, but the newer RX has about 2.4 inches more wheelbase.

That allows Lexus to change cabin proportions without making the SUV substantially longer from bumper to bumper.

The change is easier to see when comparing the third-generation RX, fourth-generation RX, and fifth-generation RX side by side.

Lexus RX 350 Interior Dimensions

The current RX 350 is designed as a five-seat, two-row SUV.

For 2026, Lexus lists front legroom at approximately 41.1 inches (1,043 mm) and rear legroom at about 37.4 inches (949 mm). Published shoulder-room figures are approximately 58.1 inches in front and 56.5 inches in the rear.

These figures help explain why exterior length alone is not enough when comparing different RX generations.

Two SUVs can have nearly identical overall lengths but different wheelbases and cabin layouts. If passenger comfort matters more than exterior size, front and rear legroom, shoulder room, seating position, wheelbase, and door-opening space are more useful measurements than total vehicle length alone.

Does the Lexus RX 350 Have Third-Row Seating?

The current Lexus RX 350 is a five-seat, two-row SUV and does not offer third-row seating. If you need three rows, it is important to distinguish the current RX 350 from the earlier RX 350L, which featured a longer body and three-row seating.

The earlier RX 350L measured 196.9 inches in length and was available with six- or seven-passenger seating, depending on configuration. Its three-row configuration could accommodate up to seven passengers.

Lexus RX 350 Cargo Space Dimensions and Capacity

The 2026 Lexus RX 350 provides approximately 29.6 cubic feet of cargo space with the rear seats in normal passenger use.

Maximum published cargo capacity is approximately 46.2 cubic feet when the rear seating area is configured to provide additional luggage room.

For most buyers, the first number is more useful because it represents the space available while carrying passengers normally.

Buyers searching for Lexus RX 350 cargo space dimensions may be looking for physical measurements rather than cargo volume. Cargo capacity in cubic feet measures total available storage volume, while dimensions such as cargo-floor length, width, opening height, and width between the wheel wells determine whether a specific large item will fit. Lexus primarily publishes cargo capacity for the current RX, so owners carrying oversized items should measure the actual cargo area before loading.

Why Older RX Cargo Numbers Can Look Much Larger

You may see much larger cargo figures for older RX 350 models, but these may use different measurement standards. For a fair comparison, check vehicles measured under the same standard and consider cargo-floor dimensions and seat-folding layout, not just cubic-foot capacity.

2026 Lexus RX 350 Ground Clearance

The 2026 Lexus RX 350 has approximately 8.1 inches (205 mm) of ground clearance. This measurement gives the RX more clearance from the road surface than a typical passenger sedan and helps when driving over steep driveway entrances, speed bumps, uneven roads, snow-covered surfaces, and rough parking areas.

Different RX powertrains can have slightly different published ground-clearance figures, so check the exact model if a small difference matters to you.

Will a Lexus RX 350 Fit in a Garage?

For the current RX 350, start with these measurements:

• Length: 192.5 in / 4,890 mm

• Width: 75.6 in / 1,920 mm

• Height: 67.3 in / 1,710 mm

Then measure your actual garage.

Check the garage-door opening, door tracks, wall shelving, steps, cabinets, rear clearance, mirror clearance, and the space needed to open the driver's door.

A 16-foot-long SUV may technically fit inside a garage that is slightly longer, but that does not mean it will be comfortable to use every day.

Allow extra space around the vehicle whenever possible.

Are the RX 350 and RX 350h the Same Size?

For the current generation, the RX 350 and RX 350h share essentially the same basic exterior footprint.

Lexus lists the same general overall length, width, height, and wheelbase across current RX variants, although weight and some other specifications differ by powertrain.

That means garage and parking-space requirements are broadly similar.

If you are comparing an RX 350 with an RX 350h mainly because of exterior size, there is little difference in their overall footprint.
