How tall is Marlo Thomas? The legendary actress, author, and humanitarian stands 5 feet 4 inches (1.63 meters) tall. It’s a detail many longtime fans have wondered about, especially given her commanding on-screen presence and larger-than-life personality. While her height is average, her influence across entertainment and philanthropy is extraordinary.
As of November 2025, Marlo Thomas remains one of the most admired figures in American culture — a woman whose achievements in television, advocacy, and charity work have made her an enduring role model for generations.
Early Life and Family Background
Marlo Thomas was born Margaret Julia Thomas on November 21, 1937, in Detroit, Michigan. She grew up in Southern California as the eldest child of Danny Thomas, the beloved comedian and founder of St. Jude Children’s Research Hospital, and Rose Marie Cassaniti Thomas.
Growing up in a household surrounded by creativity and compassion shaped her future. Danny Thomas instilled in his daughter the importance of giving back, while her mother’s warmth and encouragement helped her pursue a career in the arts.
From an early age, Thomas was drawn to performing. She studied at the University of Southern California, where she earned a teaching degree before following her passion for acting.
Even in her youth, her 5-foot-4 frame stood out not for its height, but for the poise and energy she carried into every performance and public appearance.
Breakthrough Success in Television
Marlo Thomas’s rise to fame began in the early 1960s with guest roles on popular television shows like Bonanza, McHale’s Navy, and Ben Casey. Her big break came in 1966 with the ABC sitcom “That Girl.”
In the series, Thomas played Ann Marie, an aspiring actress navigating life and career in New York City. The show became a cultural milestone — one of the first to feature a single, career-focused woman as the central character.
The success of That Girl ran from 1966 to 1971, earning Thomas four Emmy nominations and a Golden Globe Award. Her confidence and charisma made her appear taller on-screen than her 5-foot-4 stature suggested.
More importantly, she helped redefine how women were portrayed in American media. The show inspired countless young women to pursue independence, careers, and self-expression during a time when gender roles were still rigidly defined.
Life Beyond “That Girl”

- “Law & Order: SVU” – recurring role as defense attorney Vivian Devereaux.
- “The Staggering Stories of Ferdinand the Bull” – voice role in a children’s project.
Thomas’s stage work has also been well-received. She has performed on Broadway and in regional theaters across the country, consistently earning praise for her talent and professionalism.
