Which is bigger, the Honda Odyssey or the Toyota Sienna?
The Honda Odyssey is slightly longer than the Toyota Sienna, making it the bigger minivan by exterior length. The gap is modest and varies by model year and trim.
Both vehicles sit in the same class and offer similar overall footprints, with comparable width and height. This article compares their exterior dimensions to show where the size difference shows up and where it doesn’t, using figures typical of recent generations.
Exterior size snapshot
Here are typical exterior dimension figures for recent generations of each model to illustrate the size difference. Note that exact numbers vary by model year and trim.
- Honda Odyssey: Exterior length around 205 inches; wheelbase about 118 inches; width near 78 inches; height close to 68 inches.
- Toyota Sienna: Exterior length around 203–204 inches; wheelbase about 120 inches; width near 78 inches; height around 68–69 inches.
Overall, the Odyssey tends to be the longer vehicle, while the Sienna’s wheelbase is comparable or slightly longer depending on the year. These small differences can affect cargo access and ride feel, but the two vans remain closely matched in size.
Practical implications of size
Because the size gap is narrow, parking, garage fit, and maneuverability are broadly similar for most drivers. The slightly longer Odyssey may provide a touch more cargo space in some configurations, while the Sienna’s longer wheelbase can influence ride quality and interior legroom in certain trims. Always verify current official specs for the exact figures by model year and trim.
Summary
In recent model years, the Honda Odyssey is typically the bigger minivan by exterior length, with the difference usually about 1–2 inches compared with the Toyota Sienna. Both offer nearly identical footprints overall, so internal space and practical usage depend more on configuration and features than on raw size. If you need precise numbers for a specific year and trim, consult the official spec sheet from Honda or Toyota.
