How much luggage can fit in the Lexus IS 300h?

The Lexus IS 300h typically offers about 450 liters of trunk space with the rear seats in place, and around 1,000–1,250 liters when the rear seats are folded. These figures can vary a little by year and market, but they provide a solid guide for packing a trip or daily errands.


What follows is a detailed look at how the IS 300h accommodates luggage, including typical packing scenarios and how the space changes when you fold the rear seats. This information helps you gauge how many suitcases or bags you can carry on a given outing.


Cargo capacity by configuration


Use the following figures as general guidelines. Exact measurements can differ slightly by model year, trim, and the presence of options like cargo nets or floor mats.



  • Rear seats up: approximately 450 liters (about 16 cubic feet) of trunk space. This is the usable volume you’ll rely on for daily shopping, a couple of suitcases, or several bags.

  • Rear seats folded: roughly 1,000–1,250 liters (about 35–44 cubic feet) of total cargo capacity. Folding the rear seatbacks dramatically increases what you can carry, including longer items or multiple larger suitcases.


In practice, this means you can typically fit two large suitcases and a handful of carry-on bags with the rear seats up, or several larger items with the rear seats folded. The exact fit depends on luggage dimensions and how aggressively you organize the space.


Practical packing tips


To maximize what you can carry in the IS 300h, consider these quick tips:



  • Use soft-sided bags to better conform to trunk contours and maximize space.

  • Pack heavier items at the wheels side to help maintain balance and prevent tipping when the trunk is closed.

  • Fold the rear seats for long items like skis, golf bags, or multiple boxes; use the space-efficient two-piece configuration if available.


With thoughtful packing, the IS 300h can handle a weekend away, a couple of large shopping trips, or a modest road trip with a few friends and their gear.


What fits for common trips


Here are typical scenarios that illustrate how much luggage you can usually take on a trip without sacrificing passenger comfort.



  • Two adults, two large suitcases, and two carry-ons with rear seats up.

  • Two adults plus several small bags when traveling light on longer trips; folding seats increases flexibility for extra bags.

  • Longer items like a set of golf clubs; fold the rear seats to accommodate the length and secure items properly.


These scenarios reflect everyday use and should help you plan packing for weekend getaways or business trips. If you have a specific loadout in mind, sharing the item sizes can help estimate whether they’ll fit with the seats up or if you’ll need to fold the seats.


Summary


The Lexus IS 300h strikes a balance between a stylish compact sedan and practical cargo space. With the rear seats up, expect around 450 liters of trunk space; fold the rear seats to gain roughly 1,000–1,250 liters for larger luggage or longer items. For precise numbers on your exact model year and market, consult your owner's manual or the official Lexus specifications for your vehicle.
