Sigourney Weaver is 5 ft 11 in (180 cm) tall, the figure most reference sources use. She has also said she reaches 6 ft 3 in in heels, which is why many fans believe she is taller than six feet.
The actress behind Ellen Ripley in Alien, Dana Barrett in Ghostbusters and Dr. Grace Augustine in Avatar has been asked about her height for almost five decades. She has described it as both a weight on her confidence and a barrier in casting.
This article sorts out her real measurements, explains why they differ from site to site, and shows what a 5 ft 11 in frame did to her career, from lost romantic leads to the part that made her famous.
Sigourney Weaver’s Height in Feet, Inches and Centimeters
Her height without shoes is 5 ft 11 in, or about 180 cm (1.80 m). Wikipedia calls her known for her height and lists 180 cm. CelebHeights, a site that tracks celebrity measurements, gives her peak as 5 ft 11 in (180.3 cm) and cites a 1989 Dallas Morning News interview in which she said so herself.
The numbers side by side:
- Without shoes: 5 ft 11 in (about 180 cm)
- In heels, by her own account: 6 ft 3 in (about 191 cm)
- Reported at age 11: 5 ft 10½ in to 5 ft 11 in, depending on the source
CDC survey data from 2015 to 2018 puts the average adult woman at about 5 ft 3½ in, which means Weaver stands roughly 7½ inches above the average. In a business where leading men are expected to tower over their partners, that gap mattered far more than the number itself.
If you need the short answer to quote, it is 5 ft 11 in, or 180 cm.
Why Her Height Appears Differently on Different Sites
Open five celebrity profiles and you will find three or four different figures. Most of the variation comes from conversion mistakes, heels, and height being reported at different ages.
Some profile sites print 5 ft 11 in next to 1.82 m. Those two numbers do not match, because 5 ft 11 in works out to about 1.80 m. Fan discussions on CelebHeights also argue for an extra quarter or half inch, but those are forum opinions, not measurements.
The 6 ft 3 in figure causes the rest of the confusion. It is her own number for heels, and it spread through an Independent interview that Looper later summarized.
No studio biography or medical record I could find gives a measurement for her. Every figure above comes from her own comments or from reference sites, so it belongs in the widely reported category, not the officially confirmed one. Her own statements are the closest thing to a primary source.
Is Sigourney Weaver Six Feet Tall?
Not by the numbers most sources use. At 5 ft 11 in she is one inch short of six feet, and the 6 ft 3 in figure only applies with heels on. Calling her a six-footer rounds up by an inch, which is how most people talk about height.
The label sticks because her height is one of the first things people think of. The Mail & Guardian writer who met her in 2009 said it comes up alongside her intelligence and refined bearing whenever her name does.
A Tall Girl Who Reached Her Height Early
Weaver was born Susan Alexandra Weaver on October 8, 1949, to the television executive Pat Weaver and the actress Elizabeth Inglis. Wikipedia says she reportedly reached 5 ft 11 in by age 11. A magazine profile puts her at 5 ft 10½ in at that age, and CelebHeights says she hit about 5 ft 10½ in at 13.
The sources differ by half an inch and two years, so the safest summary is that she was close to her adult height before high school.
Wikipedia records her recalling that she felt like “a giant spider” and doubted she could ever act. Looper, citing the New York Times, reports that her parents sent her for medical testing because her height looked so unusual.
Her name changed in the same years. At 14 she began calling herself Sigourney, taken from a minor character in The Great Gatsby, and the Mail & Guardian notes that she liked how long and curvy it sounded for someone her size.
She moved through the Brearley and Chapin schools before reaching the Ethel Walker School in Connecticut, where her interest in performing took hold. A magazine profile records her mother’s advice that she might dislike her height then but would be glad of it someday.
School theater gave an early sign of that. She appeared in a school adaptation of The Highwayman and played a Rudolph Valentino character in a version of The Sheik, a male lead.
How Height Shaped Her Casting
1: The Roles She Says She Lost
Weaver has never pretended that height was free. In the 1989 Dallas Morning News interview, she said she had lost a lot of roles because of it. Years later she told the Mail & Guardian that it kept her away from conventional directors and conventional love stories.
A magazine profile carries her saying she was never the babe in movies because she was too tall. Looper adds that leading men often look bigger on screen than they are, which makes a very tall actress harder to pair with them.
The sources reviewed for this article do not name the specific projects she lost, so that list is not publicly known.
2: The Roles Her Height Helped Her Win
The same frame got her into the room for Alien. Wikipedia notes the Ripley part was first slated for Veronica Cartwright before a late casting change put Weaver in the lead. She was in her late twenties at the time. Looper reports that she arrived at her audition in what she calls “hooker boots” to play up her height.
She has also said her stature sometimes put her in the running for parts that, like Ripley, were first written for men. That fits a filmography built around commanding women.
After a small part in Annie Hall and her breakthrough in Alien, she played Dana Barrett in Ghostbusters in 1984 and returned as Ripley in Aliens in 1986. Variety said she was then the only actress who could sell an action movie on her name.
She won two Golden Globes in 1989, for Gorillas in the Mist and Working Girl, and later played Dr. Grace Augustine and Kiri in the Avatar films.
3: Roles Built Around Authority
Read down her list of characters and a pattern shows. Ripley is a warrant officer, Grace Augustine runs the Avatar program, Dian Fossey is a primatologist, Katharine Parker is a corporate executive, and Elaine Barrish in Political Animals is a Secretary of State. In late 2024 she added Prospero in The Tempest, a part Shakespeare wrote for a man. These are jobs that carry authority, which is a quality a tall frame tends to project on camera.
4: What the Lost Roles Cost Her
The Mail & Guardian reported that she earned $30,000 for Alien and $11 million for Alien: Resurrection, the fourth film in the series. Those figures are as reported by the paper and are unconfirmed by the studios. Whatever work her height cost her, it did not stop her pay from rising sharply as the franchise grew.
What a Tall Lead Changes on Screen
This part is judgment, not reported fact, but the pattern is hard to miss. An actress who can look a male co-star in the eye does not need a speech to read as his equal. Ripley’s scenes depend on that kind of silent parity, and Weaver’s frame supplied it before the script did.
It also explains why the same trait cut both ways. Directors who wanted a conventional love story saw a problem. Directors who wanted a believable survivor or scientist saw an advantage.
Not Every Early Setback Was About Height
Weaver’s path was not smooth even before Alien. Wikipedia says she had little luck landing lead roles at Yale School of Drama, where some teachers called her talentless and told her to stick to comedy.
None of the sources reviewed for this article ties those comments to her height, so it would be a stretch to blame it. Comedy did become a steady part of her work, from Ghostbusters in 1984 to Galaxy Quest in 1999 and Baby Mama in 2008.
What She Has Said About Her Height Over the Years
Her own comments are the best primary evidence available, and they stay consistent across decades. In 1989 she gave the 5 ft 11 in figure and added the 6 ft 3 in heel number in the Dallas Morning News, according to CelebHeights. She was already treating the height as a plain fact of her working life.
By 2009 the Mail & Guardian was reporting her view that height had cost her work with conventional directors and in conventional romances. The theme sounds the same twenty years later, which suggests the issue was not a one-off complaint.
In 2019 Parade, as cited by Wikipedia, recorded her looking back on a girlhood when she felt oversized and unsure she could act. Together, the interviews trace a 30-year shift from complaint to acceptance, with the numbers staying the same.
The Legacy of a Tall Action Lead
Wikipedia describes her portrayals of action heroines as pioneering and calls Ripley a significant female protagonist in cinema history. In 2024 the Spanish film academy gave her the International Goya Award for creating complex and strong female characters, and Venice gave her its Golden Lion for lifetime achievement.
Neither honor mentions height. It is still part of how she built those characters on screen.
Does Weaver Still Measure 5 Ft 11 In at 77?
Weaver turned 77 on October 8, 2026. Adults commonly lose a little height with age, and fan threads on CelebHeights debate whether she has lost about an inch. That is speculation. She has not published a current measurement, so 5 ft 11 in is best read as her peak height, not a confirmed present one.
She remains busy on screen. Wikipedia lists her in The Mandalorian and Grogu, released May 22, 2026, and in a Tomb Raider series for Prime Video, and says she will return for Avatar 4 and Avatar 5. Expect her height to keep coming up as those projects arrive.
