Avicularia purpurea can reach a length of about 5 centimetres (2.0 in), therefore it is among the smaller members of the genus Avicularia.

In daylight this spider discloses a quite intense purple-blue iridescence on the dorsal surface of the cephalothorax and on legs, palps and chelicerae.
The long setae covering the legs and palps are dark red-brown.
The tarsal and metatarsal scopulae are very dark brown.
The tarsal tufts are pale cream-pink in colour.
The abdomen is velvet-black and covered with stinging hairs.
