How long will my child's car seat last?

It is a common myth that car seats are outgrown by age. In reality, all car seats are certified by strict height and weight limits.

Because every child grows differently, age is only ever a rough guide.

Please note that this calculator is a prediction tool only.

A car seat can be outgrown before reaching its official limits due to various other factors such as physical proportions (children with longer torsos outgrow seats faster), the seat shell size and the overall seat design.
