Buying Guide for the Best Roof Boxes

Choosing the right roof box can make your travels much smoother, but with so many options, it’s important to find one that really fits your lifestyle and car. Think about what you'll be carrying, how often you'll use it, and the kind of trips you take—are they family road trips, ski holidays, or occasionally hauling extra gear? Focusing on your needs helps ensure you get a roof box that’s both practical and easy to live with. Let’s break down the main features and what to consider with each.
Capacity (Volume)Capacity tells you how much the roof box can hold, usually measured in liters. This is important because it determines whether all your luggage, sports equipment, or camping gear will fit inside. Roof boxes typically range from small (around 300 liters), medium (between 350-450 liters), to large (over 500 liters). If you only need extra space for a few small bags or just occasional use, a small box works well and is often easier to store when not in use. For larger families or when transporting bulky items like skis or strollers, a bigger capacity is more helpful. Always consider both the number and the size of items you usually pack when deciding.
Dimensions (Length, Width, Height)The dimensions of a roof box affect both what you can fit inside and how well it fits on your vehicle. Length is especially important for items like skis or fishing rods, while width and height impact both what you can carry and your vehicle’s clearance after installation. Roof boxes come in shorter, wider shapes (good for general cargo) and longer, slimmer ones (better for skis). Make sure the box fits your car’s roof and doesn’t block the trunk from opening. Think about the size of your gear and how your car is used to pick the right dimensions.
Load Limit (Weight Capacity)Load limit is the maximum weight the roof box can safely hold, usually in kilograms. This spec matters for your safety and to protect both your box and car’s roof. Some roof boxes are designed for lighter loads (up to 50 kg), while others can take heavier gear, sometimes up to 75 kg. Note that your car’s roof and crossbars also have their own limits, and you must stick to the lowest of these numbers. If you plan to carry heavy things like camping gear, check both your car’s and roof box’s capacity.
Opening MechanismThe way a box opens makes a big difference in how easy it is to use. Some roof boxes open from one side, while others open from both sides or even from the rear. Boxes that open from both sides are much more convenient when loading or unloading, especially in tight parking spaces. Consider your usual parking situations and whether you might need to access gear from different sides of the car.
AerodynamicsAerodynamic design affects wind noise, fuel consumption, and stability when driving at higher speeds. Streamlined boxes create less drag, making your drive quieter and more efficient. Sleeker boxes are ideal for frequent highway use and long journeys, while aerodynamics might matter less if the box is only used for short, slow trips. Think about how far and fast you usually drive with the box installed.
Mounting System CompatibilityBefore buying, it’s important to check that the roof box will securely fit your car’s roof bars or rack system. Most boxes work with standard crossbars, but some require specific shapes or sizes. Many modern boxes use tool-free, quick-mount systems, making installation quick and straightforward. If you’ll take the box on and off often, look for user-friendly mounting systems.
Security FeaturesSecurity is about keeping your gear safe while in transit or parked. Most roof boxes lock, but some have more advanced central locking or multi-point locks for added safety. If you plan to leave the box unattended for long periods or carry valuables, a more robust lock is recommended. Pick a security level that matches where and how you park and what you carry.
Weather ResistanceYou want your gear to stay dry and protected. Good roof boxes are made from weather-resistant materials and have watertight seals to keep out rain and dust. If you’ll travel in harsh conditions (snow, rain, or a lot of dust), prioritize a box known for its weatherproofing. Consider reading user reviews to verify real-world performance.
