This site displays carseat measurements and data gathered by various members of the www.car-seat.org website.  We hope that the data is as accurate and complete as possible, but the only way that can happen is if people submit their data and verify other people's data.  If you see any data that is missing or not accurate, please submit your own data using the submit forms found on this website.  If you have questions regarding what each measurement or data column on the spreadsheet represents, please view the definitions page for a description of each field.

 

Use these measurements as a tool to help narrow down which carseats might be good for specific situations. It is important to keep in mind though that measurements do not always provide the full picture of how a carseat might work with a child when it is installed in a particular vehicle. One carseat might last a child a year longer then another carseat even though they both may have the same exact top slot measurement. Variations in seat shapes, recline levels and padding can all play a role in determining how long a child might fit in a particular carseat.
