Safety Notices

Parents and caregivers usually shop for car seats based on their child’s weight and standing height.
However, when a car seat is installed forward-facing in your vehicle, the harness must be located at or
above the child’s shoulders. Because of this, children often outgrow their car seat before reaching the full
weight and standing height capacity of their car seat. So it’s important to measure your child’s seated
shoulder height for proper car seat fit and to better understand when your child is likely to outgrow the car
seat when reaching the top harness slot.


The Importance of Seated Shoulder Height

Children's torso lengths can vary significantly from child to child, even when children are the same height.
That’s why it’s so important to measure for your child’s seated shoulder height when selecting their
next car seat.

How to Measure Your Child's Seated Shoulder Height:

1. Sit your child on the floor against a wall.
2. Place a ruler or straight object across the top of their shoulder to mark the height.
3. Measure up from the floor to the top of the shoulder marker to get an accurate seated shoulder height measurement.

Seated Shoulder Height Label

To help you monitor your child’s fit in their car seat, BRITAX convertible car seats now include a Seated Shoulder Height Label. This label acts as a guide to let you know how much room your child has left to grow and when it’s time to look for their next child restraint. Once your child outgrows his convertible car seat, get to know your Booster Basics before making your next car seat purchase. While some children might be the right size, age and maturity for a belt-positioning booster seat, NHTSA recommends riding in a 5-point harness as long as possible and, therefore, a Combination/Harness-2-Booster seat might be your best option.
