We’re often asked what the cubic capacity of each roofbox will relate to in practical terms when packing. We do know that a Ford Focus boot is about the same size (in cubic litres) as a Thule Motion M roofbox, and a Porsche Cayenne about the same size as our Thule Motion XXL roofboxes.
Our smallest roofbox’s cubic capacity is just 300L. Our largest is 630L. You need to balance the need for space with the length of a roofbox and it’s appropriateness for the car on which it’s going. In other words it would be best not to put our longest largest roofbox at almost 2.4m onto a Toyota Aygo.
Think of a black sack/bin bag as being 80 cubic litres and you can quickly work out the equivalent storage in each of our roofboxes assuming you know your 80 times table!
Don’t worry if you’re not too sure as we’ll always use our expertise and experience to guide you as to what will and won’t work.
