The tail of a typical house mouse measures between 7 cm and 10 cm, representing roughly 75 %–100 % of the animal’s head‑body length (9 cm–10 cm). This proportion varies among species; the deer mouse (Peromyscus maniculatus) exhibits a tail length up to 120 % of its body, while the wood mouse (Apodemus sylvaticus) averages 80 % of body length.
