大 (dà) and 小 (xiǎo) can also be used to describe ages. The question phrase 多大 (duō dà) is often used to ask "how old." However, it is an informal way to ask, usually reserved for peers, close friends, or children. The phrase 几岁 (jǐ suì) is most often used for children young enough to display their ages on one hand. Adults do not normally directly ask each other's ages in a formal setting.
