I'm a 5'1 woman. I ordered the Teen size and it is perfect. It was a bit tricky to get on the first time, but gets easier with each use. The height of the teen product is absolutely perfect. I'd say it'd work for someone as much as 5��taller or shorter than me and still be perfect. I've never had so much fun getting the kids off the bus. My kids and the neighborhood kids all started screaming (sorry bus driver) with excitement as they saw me on the sidewalk. My kids and all the others loved it. My son was so proud telling everyone That's MY mom in there! Best $50 I've ever spent.
