Despite a brain volume the size of a large Australopithecus male, (546 cubic centimetres (33.3 in³)) all the characteristics of Homo erectus are clearly visible on Skull 5.
The braincase sizes of the other Dmanisi skulls are between 601 cubic centimetres (36.7 in³) and 730 cubic centimetres (45 in³).

The cranial superstructures of Skull 5, which are prominent and massive, suggest that it was probably a male.
Its face is one of the largest of any human ancestor discovered to date.
The zygomatic arches are massive with the right one displaying many traces of deformations, probably due to fractures and injuries.
Researchers estimate that the height of the individual was between 146 centimetres (4.79 ft) and 166 centimetres (5.45 ft) and his weight between 47 kilograms (104 lb) and 50 kilograms (110 lb).
