Ah, the great outdoors! Nothing beats hitting the open road with the family, the pets, or a bunch of friends, especially when you have everything packed into a handy roof box. But wait! How do you know if the roof box you’re eyeing will fit your vehicle like Cinderella’s glass slipper? Have no fear. This guide is here to help you measure your car and find that perfect roof box match.

Types of Roof Boxes

Hard Shell

Built like a tank, these roof boxes are ready to take on any challenge Mother Nature throws. Durable and rugged, these boxes are designed for severe adventurers who need the ultimate protection for their gear.

Soft Shell

These lightweight, flexible storage solutions are perfect for those who don’t want to commit to a long-term relationship with a roof box. Soft-shell roof boxes are easy to install and remove for weekend getaways.

Measuring for Fit

Time to break out the measuring tape! To ensure your roof box fits your vehicle like a glove, you’ll need to measure the following:


Measure the length of your roof to determine the maximum roof box length your vehicle can accommodate. Remember, longer isn’t always better – you don’t want the roof box hanging over your windshield or rear window, do you?


Next, measure the width of your roof to see how wide your roof box can be. Be sure to leave enough space on either side for your vehicle’s doors to open without any interference.


Lastly, measure the height of your vehicle to ensure your roof box won’t turn your car into a low-riding street racer. Add the height of the roof box to your vehicle’s height, and make sure it doesn’t exceed any legal height restrictions or parking garage limitations.

Roof Box Brands

Now that you have your measurements, it’s time to explore the wonderful world of roof box brands. From Thule to Yakima, there’s a roof box for every budget, style, and need. Do your research, read reviews, and make a well-informed buying decision.

Weight Limit and Distribution

Before you start loading your roof box with everything but the kitchen sink, ensure you know the weight limit of both your roof box and your vehicle’s roof. Distribute the weight evenly to prevent any mishaps or damage to your car.

Installation and Mounting System

With your roof box picked out, it’s time to install it onto your vehicle. Each roof box brand has its own mounting system, so make sure you follow the instructions carefully. In the wise words of a certain Swedish furniture company, “if all else fails, read the instructions.”

Materials and Maintenance

Whether you’ve chosen a hard or soft shell roof box, it’s essential to maintain it properly. Keep it clean, and check for any signs of wear and tear. After all, a well-maintained roof box is a happy roof box.

Securing Belongings

Pack your roof box like a pro by making sure all your belongings are secure. Use straps, bungee cords, or cargo nets to keep everything in place, even during those impromptu off-road adventures.

Aerodynamic Design and Noise Level

Choose a roof box with an aerodynamic design to reduce wind resistance and noise levels. After all, you don’t want to be serenaded by a howling roof box during your peaceful road trip.

Legality and Restrictions

Before hitting the road, make sure your roof box complies with all legality and restrictions in your area. Nobody wants to be slapped with a fine for having an oversized roof box.

Weather Impact

Consider how your roof box will fare in different weather conditions. Waterproof and weather-resistant materials are a must for protecting your precious cargo from rain, snow, and even the occasional hailstorm.

Storage Options: Roof Box vs Rack vs Trailer

When it comes to storage solutions, it’s essential to consider all your options. Roof boxes, racks, and trailers each have their pros and cons, so think about your needs and make the best choice for your adventures.

Accessories and Packing Tips

Maximize your roof box’s potential by using accessories like dividers, cargo nets, and organizers. And remember, packing is an art – make every inch count!

Safety Considerations and Loading/Unloading

Always put safety first when loading and unloading your roof box. Use a step stool or a buddy system to avoid any injuries or damage to your vehicle.
