We do not have height maximums or minimums for our strollers. We do however have recommended weight maximum limits and recommended age minimum limits, both of which can be found on each product page under the Specs section.
To figure out if each Zoe stroller would be a good fit for your child in regards to height, check out the measurements listed in the Specs section on the product's detail page. You'll notice that we provide detailed seat measurements including depth, width, and height of the seat itself as well as a measurement of seat to canopy height.
You'll want to measure your child from their waist to the top of their shoulders and compare this measurement to the setback height. Then measure your child from their waist to the to of their head and compare to the seat to canopy measurement.
It's totally ok if your child's shoulders will go above the seat back slightly. It's actually common in many strollers as children get older, but you probably won't want your child's head hitting the top off the canopy all the time. So thats measurement is probably most important when determining if your child is within the height capacity of each Zoe stroller.
