Tropidolaemus are sexually dimorphic.
Females can attain total lengths of up to 1 metre (39⅜ inches), but males are typically only around 75 cm (29 ¹⁄₂ in).
They have a distinctly broad, triangular-shaped head and a relatively thin body.

They are found in a wide variety of colours and patterns, which are often referred to as "phases".
Some sources even classify the different phases as subspecies.
Phases vary greatly from having a black or brown colouration as a base, with orange and yellow banding, to others having a light green as the base colour, with yellow or orange banding, and many variations therein.
