Choosing a roof box for luggage

Choose a roof box for suitcases, soft bags, pushchairs and everyday holiday luggage using the internal space you actually need, rather than relying on the outside size of the box.

What are you carrying?

For rigid items, internal dimensions matter most. For flexible bags and general holiday luggage, litres are a useful way to compare overall carrying capacity.

Pack bulky, lighter items on the roof.

Roof boxes are particularly useful for clothing, sleeping bags, pushchairs and other bulky luggage. Keep especially heavy items in the vehicle and always stay within the vehicle, roof rack and roof box load limits.

Find a roof box that fits your luggage

Enter the space you need

Add any one measurement below. You can combine dimensions and litres for a more precise result.

Minimum internal dimensions
OR / AND
Enter at least one internal dimension or a minimum litre capacity.
Dimensions vs litres

A 400-litre box is not automatically suitable for every 400 litres of luggage. Shape matters. If you need to carry a suitcase, pushchair or another rigid item, use its dimensions as well as litres.

Why carry skis and snowboards in a roof box?

Skis and snowboards are long, awkward items that can quickly take over the passenger compartment. Carrying them in a suitable roof box keeps the main cabin more usable and gives you a dedicated place for winter equipment.

It can also keep wet or dirty equipment away from seats, passengers and other luggage after a day on the slopes.

✓
More passenger space Keep long equipment out of the cabin so the passenger and luggage areas remain easier to use.
✓
Keep wet equipment separate Snow, water and road dirt stay away from seats, passengers and other luggage.
✓
Keep winter equipment together Skis, boards, poles and related equipment can be packed together in one dedicated space.

Check the complete roof box specification

Length and carrying capacity are only part of the decision. Check the roof box internal dimensions, maximum load and your vehicle and roof-bar loading limits before travelling.

Find a roof box for your skis or snowboards

Enter the longest ski or snowboard you need to carry, then choose how many skis or snowboards you want the roof box to hold.

This updates the active filters above and returns you to the matching roof boxes.

Ski and snowboard adapters for roof boxes

Ski and snowboard adapters are designed to help organise and support winter equipment inside compatible roof boxes. They can help keep skis or boards positioned more neatly and reduce movement inside the box.

Using roof-mounted bike racks alongside a roof box

You can often carry a roof box and roof-mounted bike rack together. The key measurements are the usable width of your roof bars, the space required by your chosen bike rack and the width of the roof box.

1. Choose your roof-mounted bike rack

Select the Thule bike rack you want to carry alongside the roof box.

Need more than one bike rack? These are our single bike racks. If you want to carry more than one bike, we offer multi-bike bundles at discounted prices. View roof-mounted bike racks & bundles →

2. Usable roof bar space explained

Choose your roof bar below and we will automatically use its usable bar length when checking whether your selected bike rack can fit alongside a roof box.

Roof Box FAQ

Learn everything about roof boxes including size selection, loading capacity, compatibility with roof bars and installation. We also explain which roof boxes best suit your vehicle, luggage needs and travel type.

Thule's roof boxes are weather resistant. Exposure to dirt, dust and light rain for a short time will not affect the contents inside the box. The hard shell makes it one of the most water resistant carriers on the market but it is not 100% waterproof.

For every box, there is a manual. In the manual there is information available about measurements of the distance you'll have to measure from the first Roof Bar position to the end, we call it distance R (see image below). You have to make sure that you can open the boot, so that the boot does not cross the end of the roof box end.

Example image: (Thule motion xt sport manual)
You'll find each box's specific measurements in the the box's instructions pdf, that you will find under the description on each box product page

See distance 'R'. To understand if you can open the hatch, measure the distance between the boot opened and where the end of the box would be and make sure the R distance is longer than the minimum distance.
You can mount every Thule roof box on Thule roof bars as long as legal requirements are followed. You will find on our Roof Box Page, a wide selection of designs, sizes, colours and features available within the Thule roof box assortment.

In the instructions of your roof box, information about requirements of your roof box is available. You can find the instructions below the description on the product page of the roof box. For all our current boxes (Thule Vector, Thule Motion and Thule Force) the requirements of the image below is what currently used for our roof boxes. Roof Box T-Track diagram We do have T-Track solutions for non-Thule roof bars that have a 20 or 24 mm T-slot in them, you can find them here
We recommend lubricating the lock and lock assemblies with an aerosol graphite lubricant. White lithium grease is also an acceptable material. Once sprayed with the lubricant allow the time for it to penetrate. Then, place a drop or two of the same lubricant on each side of the key, and insert the key into the lock. They key may need to be installed and removed several times to loosen up the pins in the lock.
When entering your car registration and selecting your roof type, vehicle specific roof bars will be shown. Within each option we will recommend a roof box for your vehicle. However, if you would like a different size roof box please get in touch with us via chat, email or phone and we can advise.
