Which is bigger, the Toyota Sienna or the Toyota Highlander?
The Toyota Sienna is bigger overall than the Toyota Highlander, primarily in exterior length and cargo space. This article compares their dimensions and capacity to help you understand which model is larger and what that means for everyday use.
Exterior dimensions: length, width, height, and wheelbase
Below are the primary exterior measurements that determine overall size and how much space you’ll be dealing with outside the vehicle.
- Exterior length: Sienna ≈ 203.7 inches; Highlander ≈ 194.9 inches. The Sienna is about 8–9 inches longer.
- Exterior width: Sienna ≈ 78.7 inches; Highlander ≈ 76.0 inches. The Sienna is noticeably wider.
- Exterior height: Sienna ≈ 69.1 inches; Highlander ≈ 68.1 inches. The Sienna sits roughly an inch taller.
- Wheelbase: Sienna ≈ 120.5 inches; Highlander ≈ 113.8 inches. The Sienna has a longer wheelbase, contributing to more interior room.
In summary, the Sienna is longer, wider, and has a longer wheelbase than the Highlander, which translates into more overall exterior space and a roomier feel inside.
Interior space and cargo capacity
Interior space and cargo capacity translate exterior size into practical everyday usability. The figures below reflect passenger room and how much cargo you can carry with various seating configurations.
- Behind the third row cargo volume: Sienna ≈ 33 cubic feet; Highlander ≈ 16 cubic feet. The Sienna offers substantially more space with all seats in place.
- Behind the second row (third row folded down): Sienna ≈ 75–80 cubic feet; Highlander ≈ 48–50 cubic feet. The Sienna continues to lead in cargo versatility when more of the cabin is freed up.
- Maximum cargo space with all seats folded: Sienna ≈ 101 cubic feet; Highlander ≈ 84 cubic feet. The Sienna provides the larger maximum cargo capacity.
These interior figures reinforce the exterior size difference: the Sienna generally offers more room for passengers and cargo in most configurations, making it the larger option among these two Toyota models.
Bottom line for buyers
If your priority is maximum overall size and cargo flexibility, the Toyota Sienna is the bigger choice. It provides longer exterior dimensions, a longer wheelbase, and greater cargo capacity across configurations. The Toyota Highlander remains a more compact SUV option with strong practicality, easier maneuverability, and traditional SUV styling.
Notes on trim options and variations
Trim level, all-wheel drive, and publishable changes can nudge exact numbers slightly, but the overall size gap remains: the Sienna is larger than the Highlander in length, width, wheelbase, and cargo capacity.
Summary: The Toyota Sienna is larger overall than the Toyota Highlander, especially in exterior dimensions and cargo space. For maximum room and a true minivan footprint, the Sienna wins; for a smaller, more SUV-like package, the Highlander is the more compact option.
