How tall is Millie Bobby Brown?

Millie Bobby Brown's height: 163 cm (5′4″)

Millie Bobby Brown is listed on this site at 163 cm (about 5′4″), the figure recorded on Wikidata. As with most actors, there is no official measured height on record, so the number should be read as accurate to about an inch. It is also a relatively recent number in a very literal sense: Brown was a child when the world first saw her as Eleven in Stranger Things in 2016, and she reached her adult height on screen over the following years.

That growth on camera is the main reason so many people look up her height. Few actors have had their adolescence documented by a global hit series the way Brown and her Stranger Things co-stars did, and comparisons between early and late seasons show how dramatically young people change between 12 and 21.

From Marbella to Hawkins

Brown was born on 19 February 2004 in Marbella, Spain, the third of four children of British parents Kelly and Robert Brown. The family moved back to England when she was four, settling in Bournemouth, and then to Orlando, Florida, when she was eight. Reliable sources do not publish her parents' or siblings' heights, so this page does not speculate about them.

Before Stranger Things, she had small roles in American TV series, including Modern Family and Grey's Anatomy. She was cast as Eleven in 2016, at age 12, and the role made her one of the most recognized young actors in the world. She was nominated for the Primetime Emmy for Outstanding Supporting Actress in a Drama Series in 2017 and 2018, and in 2018 she became the youngest person ever included in Time's list of the 100 most influential people. The same year, at 14, she became the youngest person ever appointed a UNICEF Goodwill Ambassador.

Her career since has expanded into film and business:

She married Jake Bongiovi in 2024, and the couple announced in 2025 that they had adopted a daughter. Reports cited on Wikipedia say they adopted a second child in 2026.

Growing up on screen: Stranger Things from age 12 to 21

Stranger Things is a rare natural experiment in watching children grow. Because production gaps lengthened as the show's scale grew, the time between seasons stretched from about 15 months to more than three years, while the in-story timeline advanced far more slowly.

By the show's in-story timeline, Eleven ages only about four years between season 1 and the main events of season 5. Brown, meanwhile, aged nine years, from 12 to 21. Most of the young cast experienced their full adolescent growth spurts in the gaps between seasons, which is why each new season revealed visibly taller characters. Brown's growth was part of that pattern. No reliable source publishes her measured height at each season, so this page does not invent season-by-season numbers, but published growth references show what the typical change looks like.

What the CDC growth charts say about growing from 12 to 21

The CDC's 2000 growth charts, the standard US reference for children and teens, give median heights for girls at each age. The figures below come from the CDC's published stature-for-age tables, which this site uses for its growth tools.

The pattern is clear: the median girl grows roughly 12 cm between ages 12 and 20, with the fastest growth around 11 to 13 and very little after 16. Brown's adult height of 163 cm is almost exactly the CDC median for a 20-year-old woman, 163.3 cm. A girl following the median path would be around 150 cm at 12 and within a couple of centimeters of her adult height by 15, which for the Stranger Things cast corresponds roughly to the first season and the third. Individual girls vary widely in timing, however, so this is an illustration of the average path, not a claim about Brown's own measurements. For readers curious about how adult height is predicted from childhood, the height calculator explains the published prediction methods.

How much girls vary at the same age

The median tells only part of the story, because girls of the same age differ enormously in height during adolescence. Using the CDC's published LMS parameters, the spread from the 5th to the 95th percentile looks like this:

At 12, the age at which Brown was cast, a girl at the 95th percentile is already about 163.5 cm, as tall as Brown is today, while a girl at the 5th percentile is under 140 cm. Much of that difference comes from timing: early developers shoot up first, then late developers catch up. That is exactly why a young ensemble cast can look so mismatched in one season and so different in the next, and why casting directors for long-running shows with child actors have to accept that heights will change unpredictably. The variation also explains why it is unwise to guess any child actor's adult height from early episodes. The CDC charts used here are the same references behind this site's growth tools, and a pediatrician is the right person to interpret a specific child's growth.

Brown next to her co-stars

The table compares Brown with co-stars and contemporaries using heights stored on this site. Many of her Stranger Things castmates do not have reliable listings, so only those with data are included.

In the Enola Holmes films, Henry Cavill's Sherlock towers over Brown's Enola by about 22 cm, which suits the dynamic of a famous older brother and his determined younger sister. In The Electric State, Chris Pratt is about 25 cm taller. In Stranger Things, Winona Ryder, who played Joyce Byers, is about 2 cm shorter than Brown, so by the later seasons the young actress playing Eleven was slightly taller than the actress playing one of the show's mothers. Jamie Campbell Bower, who played the series' villain in seasons 4 and 5, is about 20 cm taller.

Brown among actresses of her generation

Brown belongs to a cohort of young actresses who rose to fame as teenagers in the late 2010s and early 2020s. Using heights stored on this site:

Brown and Billie Eilish, who is listed at 162.6 cm, are essentially the same height. Jenna Ortega, another young star who led a hit Netflix series, is about 8 cm shorter, while Zendaya is about 15 cm taller. Emma Watson is an interesting historical comparison: like Brown, she grew up in front of audiences in a long-running franchise, and the two are within about 2 cm of each other as adults. Watson's Harry Potter co-star Daniel Radcliffe, who also grew up across a decade of filming, is likewise listed at 165 cm on this site. The parallel is a useful reminder that audiences who watch actors grow tend to remember them as children; many viewers still picture Brown as the 12-year-old of season 1, even though as an adult she is the same height as the typical woman in her twenties.

How 163 cm compares with British and American women

Brown holds British nationality and has lived in both the UK and the United States, so both sets of benchmarks are relevant. NCD-RisC estimates that British women born in 1996, the closest cohort on this site to her 2004 birth year, average 164.4 cm, and American women of the same cohort 163.5 cm.

By every measure, Brown is almost exactly average. The CDC's NHANES 2021–2023 survey puts the median American woman aged 20 to 29 at 163.3 cm, a fraction of a centimeter above her. She is within half a centimeter of the US and Spanish cohort averages and about 1.4 cm below the British average. In a crowd of women her age in London, Orlando or Marbella, she would stand right in the middle. The average height in the United Kingdom page shows how British averages have changed over the past century.

Why young stars' heights are often misjudged

Brown's case illustrates why the heights of young celebrities are frequently guessed wrong:

• Old footage. Images from early Stranger Things seasons, when she was 12 or 13, still circulate widely, so many people picture her as much smaller than she is.
• Co-star context. On screen she has often stood beside much taller adult actors, such as Cavill and Pratt, which makes her look petite.
• Heels and styling. At premieres she typically wears heels, which can add 8 to 12 cm and make her look closer to 5′8″ or 5′9″.
• Rapid change. Teen actors can change height by 10 cm or more between projects, so figures quoted during adolescence quickly go out of date.

Now in her twenties, Brown has reached her adult height, so 163 cm should remain a stable figure. Any small differences in future listings are more likely to reflect rounding, footwear or measurement conditions than real change, since growth in height essentially stops once the growth plates in the long bones close in the late teens.

Summary

Millie Bobby Brown is about 163 cm (5′4″), the figure listed on Wikidata. She grew up on screen in Stranger Things from age 12 to 21, a span that covered the years when girls typically grow about 12 cm, and her adult height now matches the CDC's median for a 20-year-old American woman almost exactly. She is within a couple of centimeters of the average woman in the UK, the US and Spain, about 2 cm taller than her Stranger Things co-star Winona Ryder, and about 22 cm shorter than Henry Cavill, her on-screen brother in Enola Holmes.
