You must be at least 35 years old to be president of the United States.

Quick Scoop: Basic Rule

  • The U.S. Constitution says a president has to have “attained to the Age of thirty five Years.”
  • So you can run before 35, but you must be at least 35 on Inauguration Day to actually serve.

Other Key Requirements (Very Brief)

Besides age, the Constitution also requires that a president must:

  • Be a natural-born U.S. citizen.
  • Have lived in the U.S. for at least 14 years.

Mini Example

If someone turns 35 on January 20 of an inauguration year, they meet the age rule and can legally take office that day.

TL;DR: For the U.S. presidency, the minimum age is 35, plus natural-born citizenship and 14 years of U.S. residency.
