Litoria ewingii are generally an overall light brown colour, although this may very from a white/grey to a dark brown background. They all have a white stripe along the jawline from the axilla, to at least, below the eye and sometimes to the end of the snout. Most frogs have a lighter patch on the top of the head, extending from between the eyes to the tip of the snout. The belly and throat are usually white or cream and the undersides of the thighs are bright orange. The eardrum (tympanum) is quite distinct and easily visible. The fingers and toes have slightly expanded tips (suckers) that are used for climbing, and webbing is usually absent. These are generally quite small frogs ranging from about 30-50 mm long (SVL).
