There are a few things to consider when measuring for a roof box. The first is the size of your vehicle. You’ll need to know the length, width, and height of your car in order to determine what size roof box will fit best.
The next thing to consider is the amount of gear you’ll be carrying. A larger box will obviously be able to hold more, but it’s also important to think about how easy it will be to access your gear. If you’re carrying skis, for example, you’ll want a box that opens from the side so you can easily get them in and out.
Finally, you’ll need to consider the weight of the roof box itself. The heavier the box, the more strain it will put on your vehicle’s roof rack system. With all these factors in mind, here are a few tips for measuring for a roof box:
Key Takeaways:
- Measure the length, width, and height of your vehicle. This will give you a good starting point for finding a compatible roof box.
- Think about how much gear you’ll be carrying and whether or not you need easy access to it. Skis, for example, require a different type of roof box than camping gear.
- Consider the weight of the roof box itself when making your decision.
- To measure the size of a roof box, you will need to take into account the length, width, and height of the box.
- The length is measured from the longest point at the front of the box to the longest point at the back of the box.
- The width is measured from one side of the box to the other at its widest point.
- Finally, the height is measured from the bottom of the box to its highest point.

How Do You Measure a Roof Box?
When you are ready to buy a roof box, the first thing you will need to do is measure your car’s roof. You will need to know the length and width of your car’s roof in order to choose the right size roof box. To measure your car’s roof, start by measuring from the front of the car to the back.
This is the length. Then, measure from one side of the car to the other. This is the width.
Once you have these measurements, you can start shopping for a roof box that will fit your car’s roof perfectly. It is important to make sure that you get a good fit when choosing a roof box. A poorly fitting roof box can damage your car’s paint job and cause wind noise when driving.
It can also be dangerous if it comes loose while you are driving. That is why it is so important to take accurate measurements before buying a roof box.
Can a Roof Box Be Too Big?
A roof box can be too big if it extends beyond the width of your car’s roof. It can also be too long, which will make it difficult to open your trunk or hatch. If you have a smaller car, you might want to consider a smaller roof box.
Does a Roof Box Fit into Any Bars?
No, not all roof boxes will fit into all types of bars. The size and shape of your roof box will determine which type of bar it is compatible with. In general, there are three types of bars: T-track, square bar, and aero/wing bar.
Each type of bar has its own unique mounting system, so you’ll need to make sure that your roof box is compatible with the type of bar you have before purchasing one.
How is Hatch Clearance Measured?
There are a few different ways that hatch clearance can be measured. The most common way is to measure from the top of the door opening to the top of the highest point on the roof. This measurement is typically taken with the door open and the vehicle on level ground.
Another way to measure hatch clearance is from the bottom of the door opening to the top of the highest point on the roof. This measurement is typically taken with the door closed and can be affected by things like suspension height and tire size. The last way to measure hatch clearance is from the ground to the top of the highest point on the roof.
This measurement is taken with the vehicle on level ground and can also be affected by things like suspension height and tire size.
Roof Box Size Guide
When it comes to choosing a roof box for your car, size is everything. Not only do you need to make sure that the box is big enough to fit all of your gear, but you also need to ensure that it won’t be too large and unwieldy for your vehicle. To help you select the perfect-sized roof box for your needs, we’ve put together this handy guide.
To start, measure the length and width of your car’s roof. This will give you a good idea of how much space you have to work with when selecting a roof box. Keep in mind that most boxes are designed to fit onto roofs with a minimum width of 50cm.
Once you know the dimensions of your car’s roof, take a look at our range of roof boxes and find one that best suits your needs in terms of both size and capacity. If you’re unsure which model would be best suited for your car, feel free to contact us and we’ll be happy to offer some advice.
Thule Roof Box Size Guide
If you’re in the market for a roof box, one of the first things you’ll need to figure out is what size to get. After all, you don’t want to end up with a box that’s too small or too big for your needs.
Luckily, Thule has put together a handy roof box size guide to help you make the right decision.
Here’s what you need to know:
The first thing to consider is the length of your vehicle. Thule offers three different sizes of roof boxes – small, medium, and large – so you’ll need to make sure you get one that’s appropriate for your car.
Next, think about how much stuff you’ll actually be carrying in your roof box. If you’re only going to use it occasionally for light items like blankets and pillows, a small or medium-sized box should suffice. But if you plan on using it regularly for heavier items like camping gear or sports equipment, then you’ll need to go with a larger option.
Finally, take into account the shape of your vehicle when choosing a roof box size. For example, if you have a hatchback or SUV with limited space in the trunk, then a smaller square-shaped box might be best. On the other hand, if your car has plenty of room in the trunk and/or has an aerodynamic design (like many sedans), then a longer and narrower rectangular box would work well.
Keep these factors in mind and consult Thule’s roof box size guide before making your purchase; doing so will help ensure that you get exactly the right model for your needs!
Cargo Box Sizes And Prices
Cargo boxes come in all shapes and sizes, but there are a few general categories that most companies use to determine to price. The size of the cargo box is usually based on the length of the car’s roof, with smaller cars requiring smaller boxes and larger cars requiring larger boxes. The price of the cargo box is also determined by its capacity, with larger boxes costing more than smaller ones.
There are a few other factors that can affect the price of a cargo box, such as the type of material it’s made from and whether it comes with any special features. However, in general, size and capacity are the two main determining factors. If you’re shopping for a cargo box, be sure to keep these things in mind so you can get the best deal possible.
And remember, always measure your car’s roof before ordering to make sure you get the right size!

There are many different types of Thule cargo boxes, each designed for specific needs.

Second, consider what material you want your box to be made from. Plastic boxes are usually lighter and more affordable, while metal boxes tend to be more durable. Finally, think about any special features you might want, such as a lid or lock.
Once you’ve decided on the perfect cargo box for your SUV, it’s time to install it. Most cargo boxes simply bolt onto the roof rack of your vehicle, but some require more installation than others.

Narrow Roof Box
A roof box is a great way to increase the storage capacity of your vehicle, but it’s important to choose the right size for your needs. A narrow roof box is ideal for smaller vehicles or if you need to maximize space on your roof. Here are some things to consider when choosing a narrow roof box:
Capacity: How much stuff do you need to store? Make sure to check the capacity of the roof box before purchasing.
Dimensions: Measure the length and width of your vehicle’s roof so you know what size will fit. A narrow roof box will be shorter and narrower than a standard one.
Installation: Some roof boxes require special installation kits or brackets. If you’re not comfortable installing it yourself, make sure to get help from a professional.
Weight: The weight of the empty roof box will add to the overall weight of your car, so keep that in mind when deciding which one to buy.
Best Cargo Box
If you’re in the market for a cargo box, there are a few things you’ll want to keep in mind. First, consider the size of your vehicle. You’ll need to make sure the box you choose is big enough to hold all the gear you want to transport, but not so large that it won’t fit in your car.
Second, think about how you’ll be using the box. If you frequently go on long road trips or camping trips, you’ll want a model with plenty of storage space and easy access. On the other hand, if you just need extra space for occasional errands or short trips, a smaller box will suffice.
Finally, take into account your budget. Cargo boxes can range in price from around $100 to $500 or more, so it’s important to find one that fits your needs without breaking the bank. With these factors in mind, let’s take a look at some of the best cargo boxes on the market today.
One option worth considering is the Thule Motion XT XXL Roof Box. This massive box has a capacity of 21 cubic feet, making it ideal for storing everything from skis and snowboards to camping gear and luggage. It’s also designed for easy loading and unloading, with wide-opening doors that swing open up to 270 degrees.
And thanks to its aerodynamic shape, it won’t add too much wind noise or reduce fuel economy when driving. The only downside is its high price tag; at $949, it’s one of the most expensive cargo boxes on the market.
For something more affordable, check out Yakima’s SkyBox Carbonite 21 Roof Box.
It also has 21 cubic feet of storage space and wide-opening doors for easy access, but its sleek carbon fiber construction makes it considerably lighter than the Thule box (just 46 pounds). That means it’s easier to install and remove from your roof rack—a definite plus if you plan on using it often. It also comes with an integrated lock system to keep your belongings safe while on the road.
Prices start at $649 for this model.
