You can find a size chart on our RideSafer product page right below the size drop down menu.
If your child seems like he would be in between sizes and you don’t know which to go with, we look more closely at height for proper fit.
We typically start recommending a large when the child is 45″ tall. With the understanding it will seem loose at first and may have a gap at the shoulders when sitting in the car. This is OK as long as the seat belt is being properly positioned mid-chest/mid-shoulder and across his lap/hips.
If your child has special needs and/or likes to wiggle out of restraints, we recommend a tighter fit and may recommend a small until the child would fit better in a large.
