a Roof Cargo Box

It's understandably important for you to have everything you need while driving. If you need more storage space than what's inside of your vehicle, it's time to consider buying a roof cargo box

Before you buy a roof cargo box, it's beneficial to know what you can store inside of it. So, what can you fit in a roof cargo box?

Let's take a look at what you should and shouldn't try to fit in a roof cargo box.

What Type of Cargo Box Do You Need?

Before learning what to place in a roof box, it's a good idea to learn how these products differ from one another. Here is a quick look at the three most popular types of cargo items for the roof of your automobile.

Cargo Bag

If you need something a bit more budget-friendly, roof cargo bags might be the perfect option. Cargo bags are also great for situations when you need a smaller amount of storage space. With that said, a bag isn't always best for someone who needs the sturdiness of a plastic roof box.

Cargo Baskets

There's nothing inherently bad about cargo baskets. It's just that these items aren't going to provide lots of storage space. Also, you won't have anything covering the tops and sides of what you're bringing along for the ride.

If you're taking a shorter trip and don't require lots of space, a cargo basket might be all you need. However, most people will either choose a cargo bag or the most popular cargo box.

Last but not least, you can also gain extra storage space with a roof cargo box. Typically, roof cargo boxes do cost a bit more than cargo bags or baskets. However, most cargo boxes feature hard and durable plastic. This protective material can provide drivers with additional peace of mind that their items will stay safe from the elements.

What Can You Fit in a Roof Cargo Box?

Some of the most important things to keep in mind are the dimensions of your roof box. If you're going to store average-sized items, you'll have a bit of wiggle room with roof box dimensions. When it comes to storing longer or otherwise oddly shaped items, the dimensions of your roof box become a much more important factor.


Almost everyone knows what it's like to watch the interior space of their vehicles fill up with unwanted suitcases. If you're dealing with this situation, a roof cargo box can be a great way to store these items. With that said, it's best to keep those heavier suitcases in your vehicle. Use your roof cargo box to stow away lighter suitcases.

Sleeping Bags and Pillows

No matter where you travel, you're going to need a place to sleep. With that in mind, you'll be glad to know that sleeping bags and pillows store exceptionally well in roof boxes. Another benefit of placing pillows, blankets, and sleeping bags in a roof box is that these things can provide an additional layer of padding for other stored items.

Camping Equipment

There's no denying that roof cargo boxes are popular among people who enjoy spending time outdoors. Considering that, you'll find that a cargo box works extremely well for storing camping equipment. If you have tents, sleeping bags, and other lightweight camping equipment, these items should fit easily inside of your roof cargo box.


Not everyone who enjoys being outside lives in areas known for warm climates. If you love snowy weather, you might be getting ready to take a ski trip. Fortunately, skis make the perfect items to store inside of your roof top cargo box. With that said, you're going to need a longer cargo box to have adequate space for your skis.


While skiing is a popular activity, many people also enjoy snowboarding. However, snowboards are often difficult to safely pack and transport inside of most cars. The lengthy dimensions of certain roof cargo boxes provide another way to take your snowboards along for the ride.

What Items Should You Not Place in a Roof Cargo Box?

It's also important to learn what items should not go in a roof cargo box. Now, let's look at three types of items you shouldn't place in your roof cargo box and what makes each one a bad idea.

Excessively Heavy Items

A roof cargo box is great at providing lots of storage. However, excessively heavy items are probably best stored inside of your vehicle. Storing heavier items in a roof cargo box might unintentionally cause you to store more than your roof box (and the top of your automobile) can carry. If what goes in your roof box goes over this item's weight limit, it can lead to all sorts of potentially dangerous problems.

Anything Larger Than the Dimensions of Your Roof Cargo Box

You'll also want to avoid placing anything inside of your roof cargo box that's larger than this item. And you don't want to be stuck transporting items in a roof cargo box that don't fit. This leaves you having to leave your roof box open, which is not safe and something you'll want to avoid at all costs.

Extremely Valuable Items

Lastly, it's best to keep valuable items inside of your vehicle and close by. While roof cargo boxes offer superior protection, there is a slight possibility that rain or other forms of precipitation can land on your items. Another option to consider would be finding a waterproof roof box.

As you can see, certain types of items fit well in most roof boxes while others won't. If you need more help choosing the right roof box, you'll want to visit theroofboxes.com. This website features expert guides on everything related to roof boxes.
