Which is bigger, Toyota Sienna or Honda Odyssey?
Historically, the Honda Odyssey has been the longer minivan, offering more cargo space behind the third row. As of 2024-2025, however, the Odyssey is no longer sold in the United States, making the Toyota Sienna the current option in new minivan shopping. In practical terms, the size gap between the two is small and depends on model year and trim level.
What counts as “bigger” in a minivan?
When people ask which model is bigger, they usually mean overall length, wheelbase (which affects interior space), passenger volume, and cargo capacity. Each of these metrics can shift a few inches or cubic feet from year to year, so it helps to compare the latest available specs for the exact model years you’re considering.
Key size factors to compare
Below are the main metrics buyers typically review. The following figures are based on the latest available model-year data for each vehicle, with minor variations by trim and year.
- Overall length
- Wheelbase
- Interior passenger volume
- Cargo capacity (behind the third row, and with seats folded)
These measurements collectively determine how spacious the vehicle feels for passengers and how much cargo can be carried in daily use or long trips.
Side-by-side size overview
Here is a concise, qualitative comparison of the two models in terms of size. Exact numbers can vary slightly by year and trim, so consult the official spec sheets for precise figures.
Length and wheelbase
The Honda Odyssey has traditionally been marginally longer than the Toyota Sienna. In recent model years, the Odyssey has measured around the low-to-mid 205-inch range, while the Sienna has been just over 203 inches. The difference is small, typically about 1–2 inches in favor of the Odyssey. By wheelbase, the Sienna often sits on a slightly longer wheelbase, which can influence ride feel and interior layout.
Interior space and cargo
Interior passenger volume for both vans is broadly similar, with seating configurations and comfort tuned for family use. Cargo capacity behind the third row tends to be competitive, though the Odyssey has historically offered a bit more rear cargo space in many configurations, while the Sienna’s longer wheelbase can enhance second-row legroom and overall interior packaging. In practice, the margins are modest and depend on the exact trim and options chosen.
Current market status and practical takeaway
As of the 2024–2025 period, the Honda Odyssey is not sold new in the United States, which means the Toyota Sienna is the primary new-minivan option for buyers seeking a family-hauler with similar footprint and capability. For used-Vehicle comparisons, the Odyssey can appear larger on paper in some years, but the Sienna remains a close competitor with modern features and a hybrid powertrain lineup that can influence perceived size through packaging and ride characteristics.
Bottom line: which one is bigger?
In terms of official, current market availability, the Toyota Sienna is the only direct new-minivan in production, so size comparisons for new buyers focus on how the Sienna stacks up to past Odyssey measurements. Historically, the Odyssey was the longer of the two, typically by about an inch or two, with more rear cargo in some configurations. The gap now is a matter of model-year specifics and is generally small. For practical purposes, both vans offer similar overall footprints and very comparable passenger and cargo versatility, with the Sienna’s modern packaging and hybrid drivetrain giving it a current-edge appeal for efficiency and technology.
Summary
The Honda Odyssey has typically been the longer minivan, but it is no longer sold new in the U.S. As a result, the Toyota Sienna stands as the current, readily available option with a footprint that is very close to the Odyssey’s historic size. If you are shopping today, size should be considered alongside fuel economy, drivetrain, and interior features; for used-vehicle comparisons, review the exact specifications for the specific model year you’re evaluating to understand the real-world differences.
