When Is Sadie Sink’s Birthday?
Sadie Sink celebrates her birthday on April 16 each year.
She was born in 2002 and therefore reached the age of 24 on April 16, 2026.
Her zodiac sign is Aries.
Because audiences watched Sink grow up through several seasons of Stranger Things, searches about her age have remained common throughout her career.
How Old Was Sadie Sink When She Joined Stranger Things?
Sink was approximately 15 years old when Stranger Things Season 2 premiered in October 2017.
She joined the Netflix phenomenon as Max Mayfield, a skateboard-riding newcomer who quickly became an important member of the show’s young ensemble.
The character developed considerably over subsequent seasons, allowing Sink to move from being a new supporting cast member into one of the series’ most prominent performers.
Her work as Max became especially acclaimed during the fourth season.
Sadie Sink Was Acting Long Before Stranger Things
She developed an interest in acting and musical theater during childhood and eventually began performing on stage.
One of her most important early opportunities came when she appeared in the Broadway revival of Annie, including performing the title role.
She later appeared in the Broadway production of The Audience, playing a young Queen Elizabeth II.
Those experiences meant Sink already had significant professional acting experience before joining Stranger Things.
How Old Was Sadie Sink in The Whale?
Sink was around 20 years old when The Whale was released in 2022.
Directed by Darren Aronofsky, the film starred Brendan Fraser as Charlie, while Sink portrayed his estranged teenage daughter, Ellie.
The performance demonstrated another side of Sink’s acting ability outside the supernatural world of Stranger Things.
Her character was confrontational, angry and emotionally complicated, giving Sink an opportunity to tackle heavier dramatic material.
Sadie Sink’s Fear Street Movies
Sink also became closely associated with Netflix’s Fear Street trilogy.
She played Ziggy Berman in the horror film series, particularly Fear Street Part Two: 1978 and Fear Street Part Three: 1666.
The movies further established Sink as a performer comfortable with horror, suspense and emotionally intense roles.
Combined with Stranger Things, the trilogy helped make her one of the most recognizable young actresses associated with modern horror and supernatural entertainment.
Sadie Sink Age During Her Stranger Things Years
Sink essentially grew up alongside the series.
When she entered the Stranger Things universe, she was a teenager. By the time the show’s run concluded, she had entered her twenties and established herself as a leading young Hollywood performer.
That long period helps explain why some viewers still associate Sink with her teenage character even though the actress is now 24.
The transition beyond Stranger Things has therefore become an important stage in her career.
Sadie Sink Joins Spider-Man: Brand New Day at Age 24
One of Sink’s biggest post-Stranger Things career developments arrived in 2026.
She joined Tom Holland, Zendaya, Jacob Batalon, Jon Bernthal, Mark Ruffalo and others in Marvel and Sony’s Spider-Man: Brand New Day.
The movie opened in theaters on July 31, 2026, when Sink was 24 years old.
Her move into a major Spider-Man production represents a considerable expansion of her blockbuster career after spending years as one of the central young stars of Stranger Things.
Sadie Sink’s Spider-Man Character
Spider-Man: Brand New Day kept Sink’s character unusually secretive throughout much of the movie’s marketing campaign.
Following the movie’s release, her character was revealed as Jean Grey, the powerful mutant famously associated with the X-Men.
The reveal puts Sink in a potentially significant position within the expanding Marvel universe.
Jean Grey is traditionally one of the X-Men’s most important characters, known for her extraordinary telepathic and telekinetic abilities and her connection to the Phoenix.
If Marvel continues developing Sink’s version of Jean Grey in future projects, the role could become one of the defining parts of her post-Stranger Things career.
Sadie Sink Has Built an Impressive Career by 24
At just 24 years old, Sink already has experience across Broadway, streaming television, independent drama, horror movies and superhero blockbusters.
Her notable projects include:
- Annie
- The Audience
- Stranger Things
- The Glass Castle
- Fear Street Part Two: 1978
- Fear Street Part Three: 1666
- The Whale
- A Sacrifice
- O’Dessa
- Spider-Man: Brand New Day
This variety is significant because Sink has avoided being defined entirely by one type of character despite the enormous popularity of Max Mayfield.

Being 24 years old in 2026 gives Sink considerable room to continue evolving as an actress.
She has already experienced several distinct stages of a career that began during childhood: Broadway performer, teenage television star, acclaimed dramatic actress and now major superhero-franchise performer.
Her next few years could be particularly important.
With Stranger Things behind her and her Marvel involvement opening another chapter, Sink is moving from being known primarily as one of television’s most recognizable young stars toward establishing a broader adult film career.
