how tall are you in spanish

The most natural way to say “how tall are you?” in Spanish is:
- ¿Cuánto mides?
* Informal, used with friends, people your age, kids.
If you need to be more formal (with a stranger, older person, in a professional context), you can say:
- ¿Cuánto mide?
* Uses the formal “usted.”
Both literally mean “how much do you measure?” and are what native speakers actually use to ask someone’s height.
