The core “Golden Girls” cast members were all in their early to mid‑60s (except one in her early 50s) when the show premiered in 1985. Their characters, however, were mostly written as being slightly younger (mid‑50s for most, late 70s for Sophia).

Ages of the actresses at the start

  • Bea Arthur (Dorothy): About 63 years old when the series began in 1985.
  • Betty White (Rose): Also about 63 at the show’s start.
  • Rue McClanahan (Blanche): The youngest of the four, around 51–52 when the show premiered.
  • Estelle Getty (Sophia): About 62 when the show started, despite playing the oldest character.

How old the characters were “supposed” to be

  • Dorothy Zbornak : Written as roughly 53–55 years old at the beginning of the series.
  • Rose Nylund : Also portrayed as mid‑50s, around 55 when the show starts.
  • Blanche Devereaux : Generally placed at about 53 at the start, making her the youngest Golden Girl in‑universe.
  • Sophia Petrillo : Canonically about 79 in the early seasons, the clear elder of the group.

Fun bit of context

  • Estelle Getty was actually younger than Bea Arthur in real life, even though she played Dorothy’s elderly mother.
  • The show’s premise helped redefine how TV portrayed women over 50, turning what could have been “retirement age” into an era of dating, friendship, and new adventures.

TL;DR: When “The Golden Girls” started, three actresses were in their early 60s and one in her early 50s, while the characters were mostly mid‑50s, with Sophia in her late 70s.
