Tutankhamun was about 18–19 years old when he died, with most modern expert estimates settling around 19.

Quick Scoop

  • Most Egyptologists now place Tutankhamun’s age at death at roughly 19 years.
  • Older examinations of his mummy suggested about 18, while later CT scans and bone and tooth analysis refined this to roughly 19.
  • He likely became pharaoh around age 8 or 9, ruling for close to 10 years before his unexpected early death.

Why the Age Isn’t Exact

Early 20th‑century physical examinations of his mummy gave an estimate around 18, based on bone development and height.

Later CT scans and more detailed study of bone maturity and wisdom teeth suggested he had reached about 19 years old when he died.

Because ancient Egypt did not record his exact birth date, scholars work backwards from his accession age and regnal years, which is why the age is usually given as “about 18–19” rather than a single precise number.
