There is no size on the package. If it is for a kid, it is for a big kid not like a toddler. The band looks normal size from what I can see without taking it all the way out.
I think it is a nice watch too. I will be listing a Ninja Turtle one soon. That's the only indication that I have that his could be for a big kid, but also wearable by an adult. Maybe a 12+ year old age group. Again there is no indication that I can see about size.
