The body length of full grown red-billed buffalo weavers is 21 to 25 cm (8.3 to 9.8 in) and body mass averages 82.1 g (2.90 oz) in males and 70.7 g (2.49 oz) in females.

The eyes are brown and the feet are reddish brown. The female's body is also colored dark chocolate brown, without the white flecks on the wings.
