"How old is she?" in Spanish is "¿Cuántos años tiene ella?" (kwan-toes a-nyous tyeh-neh ey-ya). Roughly translated, it means "How much years does she have?" Keep this in mind, as directly asking "How old are you?" (asking the amount of "old" that someone is) in Spanish is equivelant to "How ancient are you?"
Cuantos años tiene ella? (accent mark on the "a" in cuantos).
Ella tiene (insert # of years) años.
The expression to say how old you are or a material object is in Spanish is "tener ____ años".If you literally want to translate "years old" into Spanish, this would be "años de vejez", but this is nonsense to any Spanish speaker.
