Planning a summer road trip is exciting until you realise just how quickly your car fills up. Suitcases, camping gear, pushchairs, beach equipment… it all adds up fast.
That’s where a roof box becomes a game-changer.
At Midlands Roof Box Hire, we’re often asked:
“How much can you actually fit in a roof box?”
The answer might surprise you.
What Is a Roof Box & Why Use One?
A roof box is a secure storage container fitted to roof bars, designed to dramatically increase your vehicle’s carrying capacity without sacrificing passenger comfort.
Benefits of using a roof box:
✔ Frees up space inside your car
✔ Keeps luggage secure and weatherproof
✔ Ideal for long journeys and family holidays
✔ Makes road trips more comfortable
How Much Can You Carry in a Roof Box?
Roof boxes are measured in litres, which indicates how much volume they can hold.

💡 Tip: Soft bags pack more efficiently than hard suitcases.
Weight Limits – What You Need to Know
While roof boxes have lots of space, weight is just as important as volume.
Key weight limits to check:
✔ Roof box maximum load (usually 50–75kg)
✔ Roof bars weight limit
✔ Your vehicle’s roof load limit
Always use the lowest limit as your maximum weight.
Don’t worry we’ll help you choose the right roof box for your vehicle and load.
