Do you need Roof Bars?

You'll need some roof bars to fit these boxes. We recommend you order these directly from your vehicles manufacturer.

When it comes to maximizing the storage capacity of your vehicle for road trips, outdoor adventures, or simply for extra space, a roof box is an invaluable addition. Among the plethora of options available, Thule roof boxes stand out for their quality, durability, and variety. In this guide, we delve into the world of Thule roof box sizes to help you find the perfect fit for your vehicle and storage needs.

Understanding Thule Roof Box Sizes:

Thule, a leading manufacturer in car roof boxes, offers a range of sizes to cater to different vehicles and storage requirements. The size of a Thule roof box is typically measured in cubic feet or liters, indicating its storage capacity. Here's a breakdown of common size categories:

  1. Compact Sizes: Ideal for small cars or for carrying a few essential items. These boxes are great for day trips or solo travelers.
  2. Medium Sizes: A balance between size and practicality, these are perfect for average-sized families or longer trips. They fit most sedans and SUVs comfortably.
  3. Large Sizes: Designed for maximum storage, these are suitable for large families or for those who need to transport bulky items. They are best used on larger vehicles.
