Carbox YourSize - how to choose


The Carbox YourSize is a range of rigid high-sided bootliners that you choose (1) by the minimum width of your car boot (there are 4 width options) and then (2) by length, either fitting behind the rear seats or else sliding over the folded rear seats - there are 13 length options.

Every YourSize has straight sides so is particularly easy to slide in and out. Some people may wish to use the same YourSize in more than one car, or to choose one that's also likely to fit in their next car.

Carbox's high-sided bootliners, the Carbox Classic range, protect much more of the vehicle boot space than a low-sided liner can ever do. This is not only because of their height - up to 43cm - but because their rigid sides and fatter 'top lip' will hold your load away from the rear seat and side carpets. They are a perfect fit, following the contours of a vehicle's boot space, but the downside is that they only fit in the vehicle they were designed for.

The Carbox YourSize is made from the same material and to the same exacting standards as a Carbox Classic but, because it's straight-sided, is particularly easy to fit and remove, and it also has the potential for use in many vehicles. And, because it's not a made-to-measure product, it's also considerably cheaper.

Just as you need to wear different clothes for different jobs if you're going to do them sensibly - you don't wear your work suit for gardening or DIY or in the gym - so it is with your car, which arrives in its best clothes. You can fit seat covers to protect the seats from humans and animals, but it's the load carrying area that's probably most vulnerable to damage. This is where a Carbox YourSize makes sense, to enable you not only to protect your car but to make fuller use of it, to open up new opportunities for using a smart vehicle for ordinary household tasks, without risk of damage.

You may be moving garden rubbish - wet, dirty and with unknown creepy crawlies - or building waste, or collecting DIY materials, or you may be a tradesman who uses the same vehicle for work and family use. This is where the Carbox YourSize really makes sense - to use whenever needed, making better use of your car with only the minimum risk of damage.

YourSize are lower at the tailgate end (10cm high) to make for easy loading and unloading.

How to choose the correct width:

  • The four widths reflect the external dimensions at the widest point of the YourSize, which is at 33cm, the height of every YourSize.
  • You'll need first of all to measure the narrowest point of your boot at 33cm, and identify the provisional width.
  • Then you measure the narrowest point at boot floor level - if this is more than 6cm less than your provisional YourSize width, you'll need to drop down one size, because the width of a YourSize base is 6cm less than a YourSize top. For example, a 106cm YourSize has a base of 100cm.

For example:

  • If you measured the narrowest point at 33cm at 107cm, then a 106cm wide YourSize is your provisional choice;
  • if the narrowest point at floor level is 103cm, the 'YourSize 106' will fit;
  • if the narrowest point at floor level is 99cm, a 106cm wide YourSize will not fit, because its base is 1cm too wide.

YourSize: You may decide to choose a narrower model so that it also fits in a second vehicle.

Delivery charges and arrangements:

We charge a contribution towards delivery costs, depending on what you order, where you live, and how quickly you want the goods.

For most UK addresses, the charge for our two to three day service is 5.50 (9.50 for orders including a roof box) and our charge for Next Working Day deliveries is 8.50 (12.50 for orders involving a roof box). AutoSock, shoe chains, RUD i-Sock, and small spare parts, are charged 3.95 (Royal Mail Tracked), 4.95 (Royal Mail Express Tracked) or 5.95 (express courier, usually Next Working Day).

There are different charges for any delivery including a sea crossing, and deliveries to Skye - we will contact you with a quote on receipt of order.

Orders for Next Working Day delivery need to be received by 4.00pm.

There are no deliveries on Saturdays, Sundays or Bank Holidays, except for postable items where Royal Mail has a Saturday delivery. Next Working Day orders placed on a Friday will be delivered on the Monday, Next Working Day orders placed on a Saturday will be delivered on the Tuesday.

We are very flexible with our deliveries and will aim to deliver on a day and at an address which suits you. Goods can usually be left without signature - we prefer this with roof boxes. There's a "Special Delivery Instructions" box in the checkout area where we'll ask you to choose a typical instruction and then amend it to suit your particular requirements.

No retailer or courier company can ever "guarantee" a Next Working Day delivery. All courier companies occasionally have the same transport problems as can happen to everyone else, including snow blocked roads, closed roads, traffic jams, mechanical breakdown, an inability to find the delivery address, or to gain access to it if, for example, it's in a block of flats. We work with some of the best couriers in the business, and overall they provide an outstanding service.

Payment options:

We take the following cards, and also PayPal. Please note that the entry on your card statement will be from "The Roof Box Company".

How to measure your boot space

Measure the width of your boot at its narrowest point at a height of 33cm. Use this measurement to choose the appropriate width of YourSize (exactly or less than 92/99/106/113cm)


Measure the width at the narrowest point on the boot floor. If this is narrower by more than 6cm you will need to order one size smaller.


Measure the length of your boot at its shortest point and at a height of 33cm with closed tailgate. Make sure the Your Size you order is at least 1cm shorter than your boot length.
