Tobias is around 6 ft to 6'3 ft. In the book he has short brown hair (Abnegation style) and dark blue eyes with a light blue patch in the left iris and eyelashes that touch the skin under his eyebrows (he has long eyelashes). He is described to be fit and toned with a slight tan. The corners of his mouth turn down naturally and is often seen frowning. He has a rather large tattoo of all of the factions that symbolize who he wishes to be, though he continuously struggles with being kind.
