House mice have an adult body length (nose to base of tail) of 7. 5–10 cm (3. 0–3. 9 in) and a tail length of 5–10 cm (2. 0–3. 9 in). The weight is typically 40–45 g (1. 4–1. 6 oz). In the wild they vary in colour from light to dark agouti (light to dark brown), but domesticated fancy mice and laboratory mice are produced in many colors ranging from white to champagne to black. They have short hair and some, but not all, sub-species have a light belly. The ears and tail have little hair. The hind feet are short compared to Apodemus mice, only 15–19 mm (0. 59–0. 75 in) long; the normal gait is a run with a stride of about 4. 5 cm (1. 8 in), though they can jump vertically up to 45 cm (18 in). The voice is a high-pitched squeak. House mice thrive under a variety of conditions; they are found in and around homes and commercial structures, as well as in open fields and agricultural lands.
