The Honda Fit is a minicar that parents purchase for a wide range of reasons. Some buy it to save gas, while others buy it because it’s cheap. Still others like it for the hatchback or the ability to park it almost anywhere. Whatever the reason, it’s important to know what kinds of car seats it can fit and which combinations will allow you to fit 3 in a row across it. That’s part of why I’ve spent a while trying out all kinds of seats in the Fit to see which ones puzzle best.

Whether you’re driving a Honda Fit or one of its competitors, like the Ford Fiesta, Hyundai Accent, Toyota Prius C, Toyota Yaris, or Kia Rio, the rules for keeping your children safe while strapped in are basically the same. These are what I call the basics of best practices in car seat safety: rear-face as long as possible (ideally until at least 4!), and then forward-face for a while longer (ideally until at least 5!), and then booster until a regular belt fits your child (which typically happens between 10 and 12). The goal is to keep your children in the safest seat configuration for the longest time possible, which is important no matter what you’re driving.

However, for this information to be helpful, you need to know if a particular car seat will fit in your particular vehicle. Here are my experiences fitting a range of seats inside various years of the Honda Fit. I’ll periodically update each page as I try more seats in more positions.

Tips and Tricks:

The current generation of the Honda Fit is 160 inches long and 67 inches wide, or 2 inches shorter than the previous generation. This will make it slightly easier to 3 across but significantly more difficult to retain front-to-back room for front seat passengers compared to the previous generation.

There is still a good amount of space left for front seat occupants with the triple Coccoro installation. Use the seat belts for all three seats, as you’re not going to have a useful amount of space with LATCH.

Tips and Tricks:

This generation of the Honda Fit is 162 inches long and 67 inches wide, or 5 inches longer and 1 inch wider than the previous generation. This will make it slightly easier to 3 across and significantly easier to retain front-to-back room for front seat passengers compared to the previous generation.

There is still a good amount of space left for front seat occupants with the triple Coccoro installation. Use the seat belts for all three seats, as you’re not going to have a useful amount of space with LATCH.

Tips and Tricks:

This initial US generation of the Honda Fit is 157 inches long and 66 inches wide, making it the smallest and most difficult version of the Honda Fit sold in the US to use for 3 across installations. However, it’s still possible to make things work in it, although it’ll be a struggle. You’ll absolutely need to use seat belts instead of LATCH, and the seats are definitely going to be in contact with each other. As long as you can get independently tight installations, however, that is fine.
