It is marked size S on it. It is long. I am getting a measurement of about 12" across. I am not positive with children"s clothing . I purchased it at target. Size S
Size S is on the tag. I bought this at target for a friends daughter and it is to big for her.
I think it depends on the size of the child. It is long but looks narrow to me. Sorry I could not help more.I measured about 12 inches across if that helps.
