We have a huge range of roof boxes, covering a large variation in sizes, colours, fixing systems and loading sides.
The decision about which roof box to buy should mainly be influenced by what basic shape of box is appropriate for your requirements, which means most importantly “What width of box?” and “What length of box?”.
If you want to carry other things on the roof as well as the box, either now or later, choose a box which leaves space on the roof bars. Narrow or Medium-width boxes will suit people who want the flexibility to carry bikes, windsurfers, or kayaks. If you need to carry long items over 2 metres, you'll need a long box, whatever the width.
See our guide on loading a roof box. In this we touch on specific items, such as pushchairs, skis and other items that you may wish to use a roof box for.
- Up to 150cm long
- Up to 95cm wide
- Max capacity 500l
- Ideal for smaller cars
- Up to 205cm long
- Up to 86cm wide
- Max capacity 470l
- Popular option for holiday luggage
An important note on volume - some manufacturers are more generous than others when they quote the capacity of their boxes. When comparing different brands it's much more useful to compare the dimensions of the roof box, rather than the quoted volume.
Dual-side, left, right and rear opening boxes
We sell roof boxes that open from both sides, as well as rear opening boxes and boxes that open from one side. A left hand opening box will open from the passenger side. A right hand opening box will open from the driver’s side. Dual-side opening boxes are useful if you are using a wider roof box, particularly if you have a taller car. It's not quite as much of a concern if you are using a narrow box, where it's likely that you'll be mounting it to one side of the car anyway. Fitting a roof box in the middle of the roof may look neater but it's not very practical as you'll have to reach right over to fit and load the box (unless you go for a wider box).
A lot of smaller boxes are rear opening. They are a good option for smaller cars and will often allow you to load the box from three sides. It's not always as easy to use a rear opening box on a larger/longer vehicle.
What colours / finishes are available?
Our roof boxes come in a variety of different colours including grey, metallic silver, black and gloss black. We even sell white roof boxes.

Styling and aerodynamics
Almost all boxes are wind-tunnel tested nowadays. We sell a large range of boxes, all with slightly different styling. Like the colour and finish of your roof box, you'll have your own ideas on which boxes will look better on your car.
Quality roof boxes, combined with a set of aerodynamic bars, will often be almost silent in use.
Are roof boxes waterproof?
Our roof boxes are all made from plastic with a good overlap between the base and lid of the box. In normal weather you can expect the contents to remain completely dry. If you are driving in heavy rain you may experience some water ingress between the base and the lid of the box. This would be the case for all roof boxes. We do recommend packing your gear in suitable bags to prevent the contents getting damp.
How will a roof box affect fuel economy?
Using a roof box will reduce fuel economy but probably not by as much as you would expect, usually a few MPG. More aerodynamic boxes will give improved efficiency – look out for wind tunnel testing and aerodynamic features that diffuse the air around the box and bars. We do however, recommend that you remove the roof box when it is not in use.
Fuel economy when using a roof box will be better than if you are carrying bikes on the roof, or on a high-mount tailgate carrier, or using some roof bars on their own, so it is very important that you remove the bars when you are not using them. The exception to this is wing-shaped aluminium aero bars. Not only are the aluminium bars much quieter than the square bars but they create so little drag that most can be left in place without any significant effect on fuel consumption.
