Sigourney Weaver is 5 feet 11 inches (about 180 cm) tall, according to most reference listings, though she usually rounds up and calls herself six feet. That one-inch gap is why her height is still a talking point more than four decades after Alien made her a star.
By age 11, by her own account, she was already 5 feet 10.5 inches. Hollywood later treated that as a problem, and she built a career on parts nobody else was being considered for. Below are the figures people quote, where each comes from, and how her stature changed the roles she played.
Sigourney Weaver Height at a Glance
| Reported Height | Source | What It Means |
| 5 ft 10.5 in | Weaver’s account to Closer Weekly (2019), at age 11 | Her childhood height |
| 5 ft 11 in (about 180 cm) | Fox News; Celebrity Heights peak-height listing | The most common adult figure |
| 6 ft (about 183 cm) | Weaver in Empire; People | The rounded figure she and the press use |
| 6 ft 3 in | Closer Weekly, in heels | Not her height barefoot |
Read together, the numbers agree more than they seem to. The first is a child’s height, the second is the standard adult listing, the third is a round number, and the fourth includes heels.
In total inches, 5 feet 11 inches is 71 and six feet is 72, or about 180 cm against 183 cm.

Why the Figures Disagree
Celebrity heights rarely come from a tape measure in a doctor’s office. Most come from interviews, press material, and fan estimates, which is how a 5 foot 11 inch actress turns into a six-footer in headlines.
People and Parade both describe Weaver as six feet tall, which matches how she describes herself. Fox News gives 5 feet 11 inches. On the Celebrity Heights forum, fans argue over whether she is a shade above or below that mark, and one commenter wonders if the 5 feet 10.5 inch figure started with Weaver herself.
Headlines tend to pick a side. People and Parade lean on the six-foot figure and the tall-heroine angle, while Fox News and reference sites stay at 5 feet 11 inches. Looper stresses that being tall was never easy for her.
One newer web listing shaves her down to 5 feet 10 inches without citing a measurement. That could reflect age, rounding, or copying, and the listing gives no source for it.
Six feet also works as shorthand. It is a round number, it fits a headline, and Weaver uses it herself, so it travels easily from one interview to the next headline.
The heels number is the easiest to explain. If she is 5 feet 11 inches barefoot, the 6 foot 3 inch figure from Closer Weekly implies about 4 inches of heel. Measured against six feet, it implies 3.
Age matters too. Weaver turned 77 on October 8, 2026, and most people lose a little height over the decades, so a number from her prime and one taken today can differ slightly.
Growing Up Taller Than Everyone Around Her
Weaver told Closer Weekly in 2019 that she was 5 feet 10.5 inches at age 11 and felt like “a giant spider.” Her height was unusual enough that, according to a New York Times profile cited by Looper, her parents had her sent for medical testing.
She also towered over her mother, the English actress Elizabeth Inglis, whom Weaver has described as about 5 feet 2 or 3 inches. That mother kept telling her she would be glad of her height someday, Weaver told Empire in November 2025.
As a teenager she could not imagine loving it. She says she grew into it, helped by theater training that taught her to “embrace whatever you are” when stepping on stage, as Parade reported from the same interview.
Her height even touched her name. In a remark collected on Celebrity Heights, Weaver says she was christened Susan, decided she was too tall for the name at 12, and borrowed Sigourney from a book by F. Scott Fitzgerald.
A Shy Kid From a Television Family
Weaver’s father, Sylvester “Pat” Weaver Jr., created Today and The Tonight Show, and her mother had been an actress before retiring in the early 1940s, according to People and Fox News. Fox News adds that Weaver describes herself as very shy and vulnerable by nature.
Her mother, who had left acting behind, warned her that Hollywood was a hard place for someone so sensitive, and Weaver says she was insecure about her height as a girl. Seen next to that, the Ripley audition boots look like a deliberate act of nerve.
Too Tall to Be the Girlfriend
Her height narrowed the parts she was offered. She told The Guardian in 2016 that she was “always too tall to be the girlfriend.”
In her Closer Weekly interview she made the same point another way, saying she was never cast as the beauty, the ingenue, or the love interest. Looper adds that she has said the height cost her some big parts, in an industry where leading men often look larger on screen than they are.
In her Empire interview, reported by People, she said she once doubted she could find success in Hollywood because of her height. Given what she says about being passed over for love interests, that doubt had a practical basis.
The Alien Audition That Turned Height Into an Asset
Before Alien, Weaver worked in theater and had a bit part in Woody Allen’s Annie Hall (1977), which People credits as her movie debut. Wikipedia’s biography says she studied at Stanford and Yale School of Drama.
Alien (1979) gave her the first starring role of her career, and she was 29 when she played Ellen Ripley, as an essay on Girls on Top by Emmy Potter notes. The studio did not want an unknown in the part, but director Ridley Scott fought for her, Weaver told Closer Weekly.
She has told the story of her audition many times. She showed up in what she calls “hooker boots,” deliberately adding height, according to Looper.
Looper also reports that her height sometimes put her in the running for roles first written for men, and Ripley was one of them. That made a supposed handicap part of her appeal.
The film puts her height to work on screen. Potter’s essay points out that as Ripley grows more confident as a leader, Weaver draws herself up to her full height, which makes her more commanding against the creature on board.
Aliens (1986) pushed the idea further. Ripley goes from sole survivor to the one who protects a child and fights the alien queen in a cargo loader suit.
Her three Oscar nominations, as Parade counts them, came for Aliens (1986), Gorillas in the Mist (1988), and Working Girl (1988).
Using Height as a Character Choice
Weaver also used her stature as a performance tool. In Working Girl, she plays the polished executive Katharine Parker, and the same Girls on Top essay notes that she relies on posture and presence alone to loom over Melanie Griffith’s character, Tess.
For tall actors, the choice often comes down to slouching to fit the frame or standing straight. Ripley and Katharine Parker are both built on standing straight.
Not every role leaned on her size. In Ghostbusters (1984), she played Dana Barrett, a cellist whose apartment sat at the center of the haunting, and the comedy ran on her timing.
Directors who saw past the height mattered. Weaver told Empire, as Parade reported, that she felt lucky to be a six-foot woman with big shoulders and to find a director like Peter Weir willing to cast her. Weir directed her in The Year of Living Dangerously (1982).
Avatar and the Role Where Size Stopped Mattering
In Avatar (2009), Weaver played scientist Dr. Grace Augustine, and in Avatar: The Way of Water (2022) she returned as Kiri, a teenage Na’vi. Performance capture takes physical size out of casting, and the Na’vi stand far taller than any human anyway, which is a quiet irony for an actress whose size once limited her options.
The third film, Avatar: Fire and Ash, opened in December 2025, with Weaver on a press tour that prompted the Empire interview quoted throughout this article. People also lists The Gorge and Dust Bunny among her recent films.
How Her Height Compares With Other Women
The National Center for Health Statistics, part of the CDC, reports that the average adult woman is about 63.5 inches tall, or roughly 5 feet 3.5 inches. At 5 feet 11 inches, Weaver is about 7.5 inches above that average, and at her self-described six feet, about 8.5.
A commenter on Celebrity Heights points out that Weaver and Nicole Kidman come out at about the same height, which is a fan observation, not a measurement.
How to Read Any Celebrity Height Claim
Weaver’s case is a good test for any height listing. Check whether the number is a peak height or a current one, whether shoes were involved, and whether the source is an interview or a measurement.
Celebrity Heights lists her peak height at 5 feet 11 inches (180.3 cm). That figure sits between the 5 feet 10.5 inch childhood reading and the six-foot round number, and it fits every source above without forcing any of them to be wrong.
What Her Height Changed in Hollywood
Weaver was not the only tall actress, and one performer did not rewrite casting habits on her own. What Alien offered was a template: a woman who leads through competence and physical authority, in a film that never treats her height as a flaw.
Parade’s headline says her height helped redefine Hollywood heroes, and the story quotes Weaver on why: she has always found strength in women attractive.
The effect shows up in viewers too. Emmy Potter, who writes that she is 5 feet 10 inches tall, says seeing Weaver on screen during her formative years gave her the confidence to accept her own body.
Weaver’s mother, Elizabeth Inglis, told her she would be glad of her height one day, and by 2025 Weaver was saying she had grown into it. The trait that cost her love-interest roles brought her Ripley and a long run of characters who take charge.
The way people talk about her height has shifted since 1979. By 2019 she was recalling her mother’s prediction about it with a laugh, and by 2025 she was calling herself lucky.
