The Javan Rhino is smaller than its cousin, the Indian Rhinoceros, and is close in size to the Black Rhinoceros. The body length of the Javan Rhino (including its head) can be up to 3 to 4 m (9.8 to 13 ft), and it can reach a height of 1.4–1.7 m (4.6–5.8 ft). Adults are variously reported to weigh between 900 and 2,300 kg (2,000 and 5,100 lb), although because they are endangered, a study to collect accurate measurements of the animals has never been conducted and is not a priority. There is not a substantial size difference between genders, but females may be slightly bigger. The rhinos in Vietnam appeared to be significantly smaller than those in Java, based on studies of photographic evidence and measurements of their footprints.
Like its Indian cousin, the Javan Rhinoceros has a single horn (the other extant species have two horns). Its horn is the smallest of all extant rhinos, usually less than 20 cm (7.9 inches) with the longest recorded only 27 cm (10½ in). The Javan Rhinoceros does not appear to often use its horn for fighting, but instead uses it to scrape mud away in wallows, to pull down plants for eating, and to open paths through thick vegetation. Similar to the other browsing species of rhino (the Black, Sumatran and Indian Rhinoceroses), the Javan Rhino has long, pointed, upper lips which help in grabbing food. Its lower incisors are long and sharp; when the Javan Rhino fights it uses these teeth. Behind the incisors, two rows of six low-crowned molars are used for chewing coarse plants. Like all rhinos, the Javan Rhino smells and hears well but has very poor vision.

Most adult female grizzlies weigh 130–200 kilograms (290–440 lb), while adult males weigh on average 180–360 kilograms (400–790 lb). The average total length in this subspecies is 198 centimeters (6.50 ft), with an average shoulder height of 102 centimeters (3.35 ft) and hindfoot length of 28 centimeters (11 in). Newborn bears may weigh less than 500 grams (1 lb). In the Yukon River area, mature female grizzlies can weigh as little as 100 kilograms (220 lb). On the other hand, an occasional huge male grizzly has been recorded which greatly exceeds ordinary size, with weights reported up to 680 kilograms (1,500 lb). Although variable from blond to nearly black, grizzly bear fur is typically brown in color with white tips. A pronounced hump appears on their shoulders; the hump is a good way to distinguish a black bear from a grizzly bear, as black bears do not have this hump.
