Linnea Berthelsen: Height, Ethnicity, Languages, Stranger Things

Few characters in Stranger Things sparked as much curiosity as Kali Prasad—the punk-styled psychic who challenges Eleven’s loyalties in a single, unforgettable episode. The actor behind that shaved head and piercing gaze is Linnea Berthelsen, a Danish performer born in India whose own background raises almost as many questions as her character does.

“She shaved her head for the role of Kali in Stranger Things season 2.”

— W Magazine

“Public reporting describes her as adopted in Denmark.”

— South China Morning Post

Six key data points, one pattern: the public record is solid on the basics but thin on personal details. Here is what is verifiable.

Is Linnea Berthelsen adopted?

Who are Linnea Berthelsen’s parents?

No primary source—no interview, no family statement, no official biography—has confirmed that Linnea Berthelsen was adopted. Reporting from the South China Morning Post describes her as “adopted in Denmark,” but the statement is unattributed and the outlet offers no documentary evidence. Wikipedia simply states she was “born in India and brought up in Kalundborg, Denmark.” The identities of her parents have not been published in any credible source.

Was Linnea Berthelsen born in India?

Yes—multiple sources agree on this. Wikipedia, South China Morning Post, and the German Wikipedia entry all list her birthplace as India. The specific city or region has not been reported in any of these profiles.

The implication: the adoption question may never be answered with certainty unless Berthelsen chooses to address it directly. For now, “Indian-born Danish actress” is as precise as the public record gets.

Why did Linnea Berthelsen shave her head?

When did she shave her head?

She shaved her head for her role as Kali in Stranger Things season 2, which aired in October 2017. The look was part of the character’s punk-inspired aesthetic—a sharp contrast to the more understated appearance of Eleven. W Magazine profiled her shortly after the season dropped, noting the dramatic transformation.

Did she shave her head for Stranger Things?

Yes. The shaved head was a character choice for Kali, who leads a gang of psychic runaways in Chicago. The Stranger Things Wiki confirms the look was integral to the role. Berthelsen has not publicly discussed the experience in any widely circulated interview, so the specifics of how the decision was made remain within production.

The trade-off: the role gave her global exposure but also typecast her as “the psychic with the shaved head” in the public imagination. Later work in Devs and on stage lets her stretch beyond that first impression.

What languages does Linnea Berthelsen speak?

Does she speak Danish?

Yes. Danish is her native language. German Wikipedia and English Wikipedia both list her as a Danish speaker, consistent with her upbringing in Kalundborg, Denmark. She also trained at East 15 Acting School in London, an English-language institution.

Does she speak English?

Yes, fluently. She performed in English in both Stranger Things and Devs. The IMDb profile describes her as “British-trained and Danish,” reflecting her bilingual capability. No source has reported additional languages beyond Danish and English.

The pattern: her language skills are typical of a Danish actor who studied and works in the UK. There is no evidence of a third language, despite some fan speculation.

How tall is Linnea Berthelsen?

Is she very short?

By Hollywood standards, yes. Her height is consistently reported in the 5’0″ range. IMDb lists her at 5’0¼” (1.53 m). Parade cites approximately 5’0″ (152 cm). This places her among the shorter actors in the Stranger Things cast.

What is her exact height?

The most precise measurement comes from IMDb at 5’0¼”. Parade rounds to 5’0″. For practical purposes, 152 cm (5’0″) is the figure most commonly cited. No official source—such as a talent agency profile or casting sheet—has published a different number.

Why this matters: height trivia is a top fan query, but the difference of a quarter-inch is irrelevant. What is notable is that Berthelsen’s stature did not limit her impact—Kali’s presence came from attitude, not height.

Is Linnea Berthelsen Indian?

What is her ethnicity?

She was born in India and raised in Denmark, which gives her Indian heritage by birth and Danish nationality by upbringing. W Magazine calls her “Indian-born Danish,” a description echoed by SCMP. Her specific ethnic background within India—whether she was born in a particular region or community—has not been publicly documented.

Is she Indian or Danish?

Both, in different senses. She holds Danish nationality and identifies as Danish professionally. Her birth in India means she also has Indian heritage. Wikipedia categorizes her as a “Danish actress” while noting her Indian birthplace.

The implication: the “is she Indian?” question is a proxy for a deeper curiosity about representation in Hollywood. Berthelsen’s presence matters regardless of whether her heritage is fully documented.

Career timeline

• 2014 — Moved to London to study at East 15 Acting School (French Wikipedia)
• 2017 — Made her major on-screen debut as Kali in Stranger Things season 2 (W Magazine)
• 2020 — Played a role in the Netflix miniseries Devs (IMDb)
• 2024 — UK stage debut in Darkling at Bush Theatre, London

The pattern: Berthelsen’s career moves from a breakout Netflix role to quieter, more selective projects. She has not pursued the franchise track, instead choosing independent and stage work.

Frequently asked questions

For the curious fan, the public record on Linnea Berthelsen is a mix of solid data and notable gaps. What is confirmed—her Indian birth, Danish upbringing, bilingual ability, and striking physical choice for Kali—gives a clear picture of a performer who built a career on a single powerful role.
