The child seats and child restraints we use for testing in our car reviews on BabyDrive are to give you a general guide only.
If you are looking at the car reviews on BabyDrive and wondering if your child's restraint will fit in the car you have, or the car you are looking at buying, then below is a simple guide with the measurements of all the products we use, you can compare them to the measurements of your child seats (these are available on most manufacturers websites).
We hope this helps 🙂

Hi,
I’ve just looked at the BMW X1 review and seen 3 car seats can fit across — with the easier configuration bring two forward-facing and one rear-facing (which is what I’ll need).I’ve looked at your page ‘Will my car seat fit in my car?’
I have 2 x Britax Kid Guards and 1 x Britax Safe-n-Sound Unity Isofix capsule.
Do you believe The Unity will fit with the Kid Guards in an X1?
Yes the Kid Guards are a bit narrower so you should be fine.
Some of your reviews talk about InfaSecure car seats but none are listed here
Hi, Do you use all these different seats as they are the best to buy? Or are they just the biggest, thus all seats will fit if these do?
They’re a selection of child seat types representing some of the best-selling in Australia when we started this website in 2018. They did happen to be quite bulky compared with other brands we introduced later (https://babydrive.com.au/articles/which-infasecure-child-seats-will-fit-in-my-car/)
The dimensions are given to help people compare with the seats they own or are considering buying, and how these interact with the cars they’re researching.
Thank you very much!
