Most car roof boxes are universal and simply attach to your car roof bars when driving on the road. It is important to take into consideration how big your car is in comparison to the size of the roof box. If you own a supermini or compact car then you wouldn't consider a car roof box with a high internal volume (e.g. a Vauxhall Corsa carrying a roof box that exceeds 500 litres). It's also important to take into consideration the length of a roof box, as you should be able to open the boot of your vehicle without it hitting the rear end of the roof box whilst it's on top of your car.

How much your car roof box can carry is an important factor in understanding your car weight transportation requirements. All vehicles will have information in their supplier manual on the maximum amount it can carry when driving and should be used in the decision process of choosing a new roof box. If the box and its contents are too heavy there's a risk of damaging parts of the car. While most people are unlikely to exceed the maximum weight, it's safer for drivers to understand the limitations of their vehicle.

There is a huge selection of roof boxes on the market, and it can be difficult to identify what's best for your car. Roof box usage, price and size are all things to take into consideration when choosing a roof box. If you're only using it once a year for a family camping holiday in a large SUV then a cheap, high-volumed roof box may be the most suitable for your vehicle. If you're an avid cyclist and pairing it with a car bike rack then a smaller, higher quality roof box may be better for your requirements.
