Homo erectus weight height and body posture?

Tukana boy was aged 11 (approximately) and around 5 foot 5, probably growing to 6 feet as adult. However erectus displays a lot of regional variation. For example, the Dmanisi specimens seem to be smaller.

Weight is extremely hard to estimate, but they were more powerfully built than us, and the skellys indicate they had a stocky build. The sheer size of the handaxes shows they must have had bigger hands at least!
