Pygmy Loris shows little variation between males and females. They range from 20-23 centimeter length and 300-600 gram in weight. Weight changes seasonally, with maximum weight at the onset of winter, and lowest in spring. In summer the dorsal fur is short and thick, reddish brown in color with an orange tinge, in winter the coat is thicker and darker with a black/brown dorsal stripe, silver frosting and denser fur on the nape. Ventral fur remains white. On their face, they have a small white stripe from the nose to the forehead that changes to a blackish fork shape in the winter and is often connected to the dorsal stripe. Unlike the Bengal Slow Loris, the Pygmy Loris has a black nose, black skin on the hands and feet and little hair on the ears, which appear more obvious.
