At age 16, she remains closely associated with the Sink family and with roles that connect her work to Sadie’s established acting career.

Early Life and Family Background

Early Life

Jacey Sink was born on January 5, 2010, or 5 January 2010 in day-first format. Her birthplace is listed as the United States. Some biography profiles identify Brenham, Texas, more specifically.

Jacey grew up in the Sink household with several siblings. Her childhood has remained largely private, with little dependable public information about her school or formal education.

Claims about an early interest in art, creativity, learning, performance, and acting appear in celebrity profiles. Her actual screen work provides a clearer picture of her early acting experience than undocumented childhood activities.

Parents and Siblings

Jacey is part of the Sink family, which includes several children. Her father is reportedly Casey Adam Sink, also referred to as Casey Adam or Casey Sink. He has been described in biographies as a mathematics teacher and football coach, including work as an offensive line football coach.

Her mother is reportedly Lori Elizabeth Sink, whose name also appears as Lori Elizabeth, Lori Sink, and Lori Elizabeth Sink Baughman.

The reported five children in the family include Sadie Sink, Caleb Sink, Spencer Sink, Mitchell Sink, and Jacey. Public information about broader family events or the family’s private bond remains limited.

Relationship With Sadie Sink

Jacey Sink is the younger sister of Sadie Sink, the actress who plays Max Mayfield in Stranger Things. Their connection extends beyond family because Jacey has twice portrayed younger versions of Sadie’s characters.

Sadie’s career also includes Broadway theater. She performed in Annie in New York before gaining wider recognition through film and television.

Jacey entered the acting world on a much smaller scale. Her opportunities have included Stranger Things and The Whale, both projects in which the sisters portray the same character at different ages. This professional connection gives their sibling relationship an unusual place in their respective filmographies.

Jacey Sink’s Acting Career

Jacey Sink has three acting credits currently listed by major entertainment databases. Her early roles established a clear pattern: she often appeared as the younger version of another character.

Her acting career began on television with Stranger Things in 2019. She moved into film as Young Ellie in 2022 and returned to television as Young Lila in 2026. These acting roles remain limited in number, but each placed the young actress in a major production.

Jacey Sink in Stranger Things

Jacey appeared in the Netflix television series Stranger Things in 2019. She played Young Max, the childhood version of Max Mayfield, who is played by Sadie Sink.

Her appearance came in Season 3, Episode 6, titled “E Pluribus Unum.” The flashback scene provided a childhood memory connected to Max rather than introducing Young Max as a regular character.

The series features an ensemble cast that includes Millie Bobby Brown and David Harbour. Caleb McLaughlin and Finn Wolfhard are also part of the main cast. Jacey’s casting was much smaller in scope, with one episode credited to her role as Young Max Mayfield.

Young Max Casting: Jacey Sink and Belle Henry

Jacey Sink is not the only actress credited with portraying a younger Max Mayfield. Jacey played Young Max in Stranger Things Season 3, appearing in “E Pluribus Unum” in 2019.

Belle Henry later portrayed Young Max during Season 4. Sadie Sink continued to play the older Max Mayfield. The distinction helps separate the two child performers when looking at the show’s casting history.

Jacey Sink in The Whale

Jacey moved from television to film with The Whale in 2022. She played Young Ellie, the childhood version of Ellie. Sadie Sink portrays the older Ellie in the film.

Director Darren Aronofsky made the drama from Samuel D. Hunter’s screenplay. Jacey’s screen time as the younger character is limited, but the performance created another direct casting link between the two sisters.

The movie is also known internationally as La Ballena in Spanish-language markets. Within Jacey’s filmography, The Whale remains her only movie credit currently listed.

Jacey Sink in The Four Seasons

Jacey returned to television in 2026 with The Four Seasons. She plays Young Lila and is credited for one episode of the TV series.

Her appearance comes in Season 2, Episode 6, “Little Thanksgiving.” The episode aired on May 28, 2026, and uses flashbacks as part of its story. Jacey appears in the guest cast as Young Lila.

This 2026 acting credit extends her documented screen career beyond The Whale and updates older filmographies that end her acting activity in 2022.

Jacey Sink Movies and TV Shows

Jacey Sink’s current filmography contains three acting credits: two TV shows and one movie. Her early work is notable for younger-character roles, with each credit tied to a specific earlier stage in another character’s life.

Her Stranger Things television credit comes from “E Pluribus Unum,” where she plays Young Max. In the 2022 film The Whale, she appears as Young Ellie. Her latest listed acting credit is The Four Seasons, where Young Lila appears in “Little Thanksgiving” in 2026.

Together, these movies and TV shows form a compact acting record built mainly around storytelling that uses younger characters to show an earlier period in their lives.

Why Jacey Sink Has Played Younger Versions of Sadie Sink’s Characters

Jacey Sink has twice played younger characters whose older versions were portrayed by her sister, Sadie Sink. In 2019, the sisters were connected through Max Mayfield in Stranger Things. Jacey played Young Max while Sadie played the older Max.

The pattern returned in The Whale in 2022. Sadie played Ellie, while Jacey appeared as Young Ellie, the childhood version of the same character.

Their sibling relationship and family resemblance make the casting connection easy to recognize on screen. No publicly documented casting statement establishes that resemblance as the official reason for either choice, so the confirmed link is the roles themselves.

Jacey Sink’s Age and Current Status

Jacey Sink was born on January 5, 2010. She was 12 years old during much of 2022 and turned 15 in 2025. In 2026, she is 16 years old.

Her current status is best understood through her acting credits. After The Whale in 2022, her public filmography appeared quiet for several years. Her role as Young Lila in The Four Seasons added a new acting credit in 2026.

That appearance places her acting career beyond the 2016-2022 active-years range found in older profiles. It also gives Jacey fresh public recognition as an actress rather than leaving her screen record frozen at her childhood roles.

Public Image, Privacy, and Social Media

Jacey Sink has a limited public image compared with Sadie Sink. Most media coverage and public attention around Jacey centers on her acting credits, family connection, and appearances as younger versions of characters.

Instagram searches can surface pages, family photos, fan edits, videos, and clips from movie scenes. A clearly authenticated public account for Jacey is not established in available professional profile information.

Her relatively small online presence also leaves little dependable information about personal topics. Claims about her everyday lifestyle should therefore remain separate from documented details about her work and family.

Jacey Sink’s Height and Appearance

Jacey Sink’s height has been listed as 4 feet 3 inches, or 4’3″, which is about 129 to 130 centimetres.

Other biography pages have published 4 feet 9 inches, or 4’9″, along with physical details such as blonde hair and blue eyes. Because Jacey is still a teenager, old measurements should not be treated as a reliable statement of her current height or appearance.

Jacey Sink’s Net Worth

Jacey Sink’s net worth is sometimes reported as $1 million on celebrity biography sites. There is no dependable public financial information establishing that figure as her verified net worth.

Her known income-producing work is her acting career as an actress, including three screen credits. Without verified information documenting earnings or assets, the $1 million estimate should be treated as unofficial rather than a confirmed financial fact.

Conclusion

Jacey Sink, born Jacey Joy Sink in 2010, is an American actress whose compact filmography has a distinctive connection to Sadie Sink. She entered Stranger Things as Young Max in 2019 and played Young Ellie in The Whale in 2022.

Her acting career continued in 2026 when The Four Seasons cast her as Young Lila. That role brings her documented work to three projects and provides a current update to older profiles that stop with The Whale. From Young Max to Young Ellie and Young Lila, Jacey’s screen work now covers both film and television.
