This shirt fits my four year old very well and he is shorter thinner if you are trying to get it for a five year old I can suggest either small or maybe medium but definitely medium so they need space in it to grow, it's not big at all just extra space and if you wash it it can still shrink so a medium would be perfect but a small is just right.
