How big is the Lexus RX 300?

In brief, the Lexus RX 300 is a compact-to-mid-size luxury SUV whose footprint sits in the low-to-mid 180s inches in length, with a wheelbase around 105 inches, and a width in the low 70s inches. Interior space and cargo capacity are flexible enough for five passengers and varying amounts of luggage, with exact numbers changing by year and market.

What counts as “size” for the RX 300

To understand how big the RX 300 is, it helps to break size into exterior dimensions and interior/cargo space. The figures below reflect typical ranges for the model years when the RX 300 was sold in the United States (roughly 1999–2003) and account for minor variations by year, trim, and drivetrain.

• Exterior length: roughly 183–187 inches (4.65–4.75 m)


• Exterior width: about 71–74 inches (1.80–1.88 m)


• Exterior height: roughly 63–66 inches (1.60–1.68 m)


• Wheelbase: around 104–106 inches (2.64–2.69 m)


• Curb weight: approximately 3,700–4,100 pounds (1,680–1,860 kg)


• Ground clearance: typically 6.5–8 inches (16–20 cm)

These exterior dimensions describe a vehicle that is easy to maneuver in urban settings while still offering a tall ride height and a roomy cabin for its class. Variations across model years account for minor changes in bumpers, tires, and equipment.

Interior space and cargo capacity

The RX 300 is designed to seat five with a practical balance of headroom and legroom, especially for a compact-to-mid-size luxury SUV. Interior space is influenced by option packages and seating configurations, but the numbers below capture typical capacity ranges.

• Passenger volume: roughly 95–100 cubic feet (2.69–2.83 m³)


• Cargo behind the rear seats: about 29–34 cubic feet (0.82–0.96 m³)


• Maximum cargo with rear seats folded: roughly 60–75 cubic feet (1.70–2.13 m³)

Interior space figures reflect the RX 300’s mission as a versatile luxury SUV—capable of carrying a family and their belongings, while maintaining a comfortable, shop-friendly overall footprint. Exact cargo and passenger space depend on year, trim, and whether the rear seats are in use.

Model-year and market variations

Because the RX 300 spanned a transitional period for Lexus’ SUV lineup, exact measurements can vary by year and market. The model commonly identified as the RX 300 in the United States covers late 1990s into the early 2000s, with later generations shifting to the RX 330 and RX 350 family names, which brought changes in dimensions and packaging.

Why the numbers vary

Differences arise from incremental design updates, safety equipment, wheel/tire sizes, and optional interior features. Even within a single model year, regional variations (such as different trim levels or AWD vs. 2WD configurations) can yield small dimensional changes.

How to get exact figures

For precise measurements for a specific vehicle, consult the door jamb placard on the RX 300 you’re considering or the official Lexus brochure for that model year. Vehicle databases and the VIN-specific specification sheets from Lexus can also provide exact exterior and interior dimensions for a given car.

Bottom line

Overall, the RX 300 offers a compact-to-mid-size SUV footprint with a substantial interior for passengers and a flexible cargo area. While the exact numbers shift by year and market, buyers can generally expect an exterior length in the low-to-mid 180s inches, a wheelbase around 105 inches, and cargo capacity that scales from about 30 cubic feet behind the rear seats to roughly 60–75 cubic feet with seats folded.

Summary

The Lexus RX 300 blends ease of urban handling with practical interior space, delivering a manageable exterior size for a family-oriented luxury SUV of its era. If you need the precise dimensions for a specific model year or region, check the official Lexus materials for that year or consult the vehicle’s door placard and VIN-based specifications.
