Mason Thames Physical Details
Mason Thames stands at an estimated 5 feet 10 inches, though no official height has been confirmed through a verified source. Like many young actors, his exact stats are not listed on a studio bio or verified fan wiki with full confidence, so any number circulating online should be treated as an estimate rather than fact.
His build reads as lean and athletic on screen, which suits both his horror roles and his more physical parts, such as Hiccup in How to Train Your Dragon. He has brown hair and blue eyes, features that have made him a recognizable face across very different genres, from a scared kid in a basement to a Viking teen bonding with a dragon.

Fans looking for Mason Thames height searches often expect a hard number the way you would find on an athlete’s roster. Actors rarely publish that kind of data, so treat any figure you see as a rough guess dressed up as fact.
Mason Thames Early Life and Background
Mason Thames was born on July 10, 2007, in Dallas, Texas, and grew up in the nearby city of McKinney. He attended school in Prosper, Texas, a fast growing suburb north of Dallas. That Texas upbringing shows up again and again in interviews, where he talks about heading home to “bed rot” after a packed year of press tours.
His early life did not follow a traditional Hollywood script. Instead of moving to Los Angeles as a small child, he started out local, working in short films and Texas based productions before national casting directors took notice. This grounded, non industry childhood is something Thames has pointed to as a reason he stayed level headed once fame hit fast in his late teens.
Reports describe him training in performance disciplines, including ballet, before he shifted his focus fully toward acting. That kind of movement based training often helps young actors handle physical roles, and it lines up with how comfortable he later looked doing stunt heavy work on a set like How to Train Your Dragon, which filmed for nine months in Ireland.
Growing Up in Texas
Thames has described his hometown area with clear affection. Rather than distancing himself from Texas once he became known in Hollywood, he leans into it, often returning home between projects instead of settling on the West Coast full time.
Mason Thames Family
Mason Thames keeps his family life mostly private, which is common for actors who became famous as minors. Public reporting has not confirmed detailed, verified information about his parents’ names or occupations, so any specific claims you see about them should be treated with caution rather than accepted outright.
Mason Thames Parents
Solid, verified details about Mason Thames parents are limited in mainstream reporting. What is consistently reported is that his family supported his early acting pursuits from Texas, helping him balance auditions, travel, and schooling well before he became a lead actor. Because he was a minor for most of his career so far, a parent or guardian would have needed to accompany him to sets, which is standard industry practice.
Mason Thames Siblings
Some outlets reference a sister in connection with Mason Thames, though a fully confirmed profile of her identity is not widely documented in reliable sources. Treat sibling details as unconfirmed rather than settled fact.
Mason Thames Education and Career Start
Mason Thames attended school in Prosper, Texas, and balanced traditional education with an increasingly demanding acting schedule. Specifics about homeschooling versus in person schooling during his busiest filming years have not been laid out publicly, which is fairly typical for teen actors juggling long shoots.
His acting career began in 2017 with the short film After Omelas, where he played a character named Liam. Two years later, in 2019, he landed three episodes on the Apple TV+ series For All Mankind, a science fiction drama that marked his first real television credit and his first exposure to a big budget production environment.
That early work matters more than it might seem. It gave a barely teenage Thames a taste of professional set life and the pace of scripted television, well before he had to carry an entire film on his shoulders.
Mason Thames Career Highlights
Mason Thames movies took a sharp turn upward in 2021 with The Black Phone. He played Finney Blake, a quiet, resourceful teenager held captive by a masked killer played by Ethan Hawke. Directed by Scott Derrickson and backed by Blumhouse, the horror film grossed over 161 million dollars worldwide against an 18 million dollar budget, a result that turned Thames from an unknown into a name casting directors watched closely.
From there, his career highlights stacked quickly:
- The Black Phone (2021): breakout lead role opposite Ethan Hawke
- Walker (2021 to 2022): played a younger version of the lead character across two seasons
- Monster Summer (2024): starred opposite Mel Gibson in a coming of age adventure
- Incoming (2024): Netflix comedy following a group of high school freshmen
- How to Train Your Dragon (2025): played Hiccup in the live action remake, directed by Dean DeBlois
- Regretting You (2025): took on a romantic lead role in the Colleen Hoover adaptation
- Black Phone 2 (2025): reprised his role as Finney in the sequel
His performance as Hiccup earned him a Saturn Award nomination, a notable recognition for a genre heavy franchise role. He has said in interviews that Hiccup was a character he related to as a kid, since the character starts as an outsider who eventually proves himself, a theme Thames has connected to his own path into acting.
“That was my childhood, growing up with those movies,” Thames told PEOPLE about How to Train Your Dragon. “Hiccup as a character, he was my hero growing up. There’s so much about him that I could relate to.”

Special Facts About Mason Thames
Some lighter, fun details help round out who Mason Thames is beyond the resume:

Mason Thames Net Worth and Income
Mason Thames net worth is estimated to fall somewhere between 3 million and 5 million dollars as of 2026, based on his film salaries, brand exposure, and the box office scale of his recent projects. No official, audited figure has been published, so this range should be read as an informed estimate rather than a confirmed number.
His income sources include:
- Film salaries: lead and supporting roles in studio films with budgets ranging from under 1 million to over 150 million dollars
- Streaming and television work: his early For All Mankind episodes and the Walker series
- Brand visibility: high profile press tours and red carpet appearances, including moments tied to major fashion houses during international promotional stops
- Potential endorsement interest: rising actors at his level typically begin fielding brand partnership offers once box office numbers climb
Young actors coming off a single breakout franchise film often see net worth estimates in the low single digit millions during their first few years. Thames’ 2025 stretch, with three films opening at number one, likely pushed his earning potential well above where he was after The Black Phone alone. Still, without an official financial disclosure, treat any specific number as an estimate.
Mason Thames Recent Updates
As of 2026, Mason Thames is coming off arguably the biggest year of his career. In 2025, three of his films, How to Train Your Dragon, Black Phone 2, and Regretting You, each topped the box office, a feat not matched by any actor since Jim Carrey in 1994. That kind of run tends to accelerate everything: bigger scripts, bigger offers, and bigger public attention.
His personal life has drawn attention too. Thames and Regretting You costar McKenna Grace went Instagram official with their relationship in February 2026, after nearly two years of fan speculation that started with a viral TikTok clip during filming. In March 2026, Grace brought him as her date to the Oscars, which many fans read as public confirmation of the relationship.
He also has an upcoming film in his lineup according to industry casting records, suggesting he plans to keep taking on varied roles rather than settling into one genre.
Lifestyle and Favourites
Away from red carpets, Mason Thames comes across in interviews as low key and homebody leaning. He has said his ideal way to decompress after a demanding shoot is doing very little at all, watching movies in bed back home in Texas rather than jumping straight into another project or a busy social calendar.
A few of his known favorites and habits:
- Favorite movie: Spider-Man 2, mentioned in multiple interviews
- Dream role: playing Spider-Man himself someday
- Downtime style: resting at home in Texas between projects, largely away from the spotlight
- Close industry friendships: he speaks warmly about How to Train Your Dragon castmates, calling them a tight knit group who lived near each other during the nine month Ireland shoot
- Public persona: quietly intense on screen, but easygoing and self deprecating in interviews
He has also talked about staying somewhat detached from online chatter about his personal life, noting he has always kept things fairly private even as public interest in him grew fast.
