Status clarification: Was Diana a princess?
Diana Spencer was not a princess by birth but became a royal styled Her Royal Highness The Princess of Wales upon marriage to the Prince of Wales in 1981. She is widely referred to as Princess Diana because she held the style Royal Highness and carried out royal duties as the wife of the heir apparent. Her sons are princely heirs, while her own formal status is that of a royal princess by marriage rather than a dynastic princess of the United Kingdom by birth.
Her official title and style
Her Royal Highness The Princess of Wales
Upon marrying the Prince of Wales on 29 July 1981, Diana gained the official style Her Royal Highness The Princess of Wales. This is a courtesy title granted to the wife of the Prince of Wales in the United Kingdom. She was commonly known as Princess Diana in media, public discourse, and general usage, reflecting her proximity to the throne and her prominent royal role.
Royal Highness versus Serene Highness
All members of the British royal family styled as Royal Highness hold that dignity by royal grant. The title Prince or Princess and the style Serene Highness are not used by junior members of the British royal family by modern convention. Diana’s correct formal style remained Her Royal Highness The Princess of Wales, while her public and affectionate shorthand was Princess Diana.
The princely status of her sons
Prince William and Prince Harry
Prince William and Prince Harry are styled as princes because they are legitimate male-line grandchildren of the sovereign and hold the rank of prince from birth. Both were granted the style His Royal Highness Prince at birth, with William additionally receiving a Dukedom. Their princely status derives from their descent from sovereigns and their place in the line of succession, not from their mother’s use of Princess Diana.

Royal hierarchy and related styles
In the British royal family, the style Prince or Princess is generally reserved for children and male-line grandchildren of the monarch, the consort of a queen regnant, and the Prince of Wales.

She was not a princess by birth, but she held a senior royal status as the wife of the Prince of Wales and performed official royal duties.
