DOT said the overall length was 38". Which is 3 feet 2 inches long. And since it's the overall length, that includes the 13.5 inch head. So the handle is only 2 feet and half an inch long. If the spear in the picture is supposed to be a representation, that means his character should be less than 3 feet tall.

But it does say short spear in the actual description, so I guess the picture probably has no bearing on it at all. 3 feet just seemed really short to me, even for a short spear.
