Mason Thames Height and Physical Appearance
Mason Thames stands about 5 feet 8 inches tall, equal to approximately 173 centimeters. Height-focused reference site CelebHeights lists him at 5 feet 8 inches, or 172.7 cm. Older online profiles sometimes use measurements taken when he was younger, which explains why different figures continue to appear in searches.
He has a lean, athletic build, brown hair, and brown eyes. His physical control is especially noticeable in roles requiring expressive movement because he trained extensively in ballet before becoming an actor. His posture and coordination help him communicate uncertainty, fear, humor, and confidence without depending entirely on dialogue.
Age, Birthday, and Texas Background
Mason was born on July 10, 2007, in Dallas, Texas. He turned 19 on July 10, 2026, and his zodiac sign is Cancer. His early years were spent in Texas, including time around McKinney and Prosper, before his expanding acting career required frequent travel and longer periods near major production centers.
His connection to Texas remains an important part of his identity. Even after achieving international recognition, he has described enjoying a quieter routine at home between projects. That balance gives him space to recover after demanding shoots, premieres, interviews, press tours, and the rapid public attention surrounding his major releases.
Parents, Sister, and Family Support
Mason grew up in a creative and supportive household. Teen Vogue reported that his father works in real estate, while his mother encouraged his artistic interests. His father also helped inspire his love of cinema by taking him to films, and Mason began making small homemade productions with neighborhood friends when he was young.
His sister, Brooke Thames, shared his early connection to dance and later became a professional ballerina. Mason studied ballet alongside her for several years, and the siblings also created homemade horror scenes and lightsaber videos. His parents continued supporting him when acting opportunities required a major commitment and a move toward Los Angeles.
Ballet Training Before Acting
Before becoming widely known as an actor, Mason spent four years studying and performing ballet. He toured with a professional international ballet company as its youngest member, gaining experience with rehearsals, live audiences, travel, physical preparation, and the discipline needed to perform consistently under pressure.
That dance background became valuable when he moved into screen acting. Ballet develops timing, balance, body awareness, and the ability to repeat carefully planned movement. These qualities can be seen in Mason’s controlled physical performances, particularly when a character must express fear or vulnerability through posture and facial reactions rather than long speeches.
Early Television and Acting Work
Mason’s screen career began with the 2017 short film After Omelas, in which he played Liam. He later appeared in Apple TV+’s science-fiction drama For All Mankind, portraying the younger version of Danny Stevens. This television work introduced him to professional sets while he was still building his confidence as a young actor.
He also portrayed a younger version of Cordell Walker in the CW series Walker. These early roles were smaller than his later movie performances, but they allowed him to work with experienced crews, understand on-camera continuity, and develop the emotional concentration that would become essential to his breakthrough role.
Breakthrough With The Black Phone
Mason achieved his major breakthrough as Finney Blake in The Black Phone, directed by Scott Derrickson. The horror film placed him opposite Ethan Hawke, who played the masked kidnapper known as the Grabber. Mason carried much of the story through Finney’s fear, intelligence, isolation, and gradual determination to escape captivity.
Derrickson praised Mason’s ability to process emotional moments honestly without overacting. The performance earned him broad attention, a Saturn Award nomination, and the Fangoria Chainsaw Editor’s Eyeball on the Future Award. He later returned as Finney in Black Phone 2, showing the character at a different stage of life.

Expanding His Movie Career
Mason moved beyond horror with the Netflix high-school comedy Incoming, playing Benj Nielsen. He also starred as Noah Reed in Monster Summer, a supernatural adventure directed by David Henrie. These projects gave him opportunities to explore comedy, friendship, adventure, and lighter coming-of-age storytelling after the intensity of The Black Phone.
His largest fantasy role came as Hiccup Horrendous Haddock III in the live-action How to Train Your Dragon. The movie became a major commercial success, and Mason described Hiccup as a childhood hero. In 2025, he also starred in Regretting You and returned in Black Phone 2, placing three of his films at the top of the box office during the same year.
Playing Hiccup in How to Train Your Dragon
Being selected as Hiccup carried personal meaning for Mason because he had grown up watching the animated films. He related to the character’s intelligence, individuality, awkwardness, and willingness to challenge the traditions of Berk. After a chemistry read in London, director Dean DeBlois surprised him during a call by offering him the role.
Mason worked opposite Nico Parker as Astrid, Gerard Butler as Stoick, and Nick Frost as Gobber. His ballet background helped with Hiccup’s distinctive posture and movement, while his emotional performance supported the relationship between Hiccup and Toothless. He is also attached to reprise the role in the live-action sequel scheduled for 2027.
Awards and Major Career Recognition
Mason’s performance in The Black Phone brought a Saturn Award nomination for Best Younger Actor in a Film. He also won recognition at the Fangoria Chainsaw Awards, receiving the Editor’s Eyeball on the Future Award. His work as Hiccup later earned another Saturn Award nomination, reflecting his successful transition from horror to large-scale fantasy.
Another important milestone came when Forbes selected him for its 2025 North America 30 Under 30 list in Hollywood and Entertainment. At 17, he was the youngest person included in that year’s class. Forbes highlighted his work in The Black Phone, Incoming, and Monster Summer while recognizing his rapidly expanding film career.
Income Sources and Professional Success
Mason’s professional income comes primarily from acting in feature films and television productions. His credits now include work for Universal Pictures, Netflix, Apple TV+, Paramount Pictures, and the CW. Leading roles, sequels, promotional appearances, and participation in valuable entertainment franchises have strengthened his position as a working young actor.
No carefully documented financial disclosure supports a precise personal net-worth figure, so his career is better measured through confirmed achievements. He has led successful theatrical films, joined two active franchises, earned industry recognition, and secured representation from WME and Brillstein Entertainment Partners, giving him access to significant future opportunities.
Lifestyle, Interests, and Future Ambitions
Away from film sets, Mason enjoys a comparatively relaxed lifestyle with his family in Texas. Teen Vogue described him spending time outdoors, joining family dinners, playing golf, and going fishing. He also has two dogs, including a pit bull-boxer mix named Brish and a black-mouth cur named Taka.
His ambitions extend beyond performing. Mason has said that he wants to direct films and sometimes watches directors work on his days away from acting. As a child, he used an iPad and iMovie to create short horror projects and action scenes, showing that his interest has always included storytelling, editing, and filmmaking.
Social Media Presence
Mason has built a large audience on Instagram, where his profile uses the handle @masonthames. His posts commonly feature film promotion, premieres, professional photography, cast appearances, and moments connected with his projects. His following grew sharply as How to Train Your Dragon and his other major films reached wider audiences.
He has spoken positively about seeing fan reactions, edits, and enthusiasm for his movies, while also recognizing the need for balance. Rather than making social media the center of his identity, he uses it mainly as a connection between his professional work and an audience following his development from child performer to adult actor.
