Mason Thames Height: The Straight Answer
Here is the number most of you came for. The figure most frequently cited for Mason Thames height is 5 feet 10 inches (178 cm). That number shows up again and again across entertainment profiles, fan databases, and biography sites.
There is a catch. Mason Thames has never publicly confirmed his exact height. No studio biography, interview, or official source lists a measured number. Every figure you see online is someone else’s estimate. The 5 ft 10 in value is best described as widely reported, not officially confirmed.
Other estimates exist. Specialist height-analysis sites that study red carpet photos place him closer to 5 feet 8 inches (173 cm). A few older teen-era profiles still list 5 feet 7 inches (170 cm). That 5’7″ number likely dates from before his late growth spurt. The honest range sits between 5’8″ and 5’10”. Most of the web has settled on 5’10” as the headline number.
Why the Numbers Keep Shifting
Celebrity heights are slippery. Fans measure actors against co-stars in photos. Those photos lie. Heels add an inch or more on red carpets. Posture changes everything. Camera angles flatter or shrink people depending on the shot.
Teenage growth makes the confusion worse. Mason Thames was cast in The Black Phone around age 13 to 14. He was a smaller kid then. He shot How to Train Your Dragon as a 16 to 17-year-old young man. He kept growing between those projects. Old profiles never updated their numbers. New estimates overshoot based on fresh photos.
So you get three layers of disagreement. Older sites still show the teen number. Photo analysts measure the current number. General biography sites split the difference at 5’10”. None of them is lying. They are just measuring a moving target at different times.
How Tall Is Mason Thames Compared to His Co-Stars?
Comparisons help. Ethan Hawke, his The Black Phone co-star, is widely listed around 5 feet 10 inches. In press photos together, Thames looks a touch shorter than Hawke. That supports the idea that Mason sits at or just under the 5’10” mark.
Tom Holland, another young leading man often compared to Thames, is generally listed around 5 feet 8 inches. Thames appears slightly taller than Holland in the few images where they overlap in press contexts. Again, this points toward the upper half of the 5’8″ to 5’10” range.
His lean build matters too. Profiles of fellow young leading men such as Chase Stokes show the same pattern: a slim, upright frame reads taller on camera than a stockier frame of the same actual height. Years of ballet training gave Thames dancer posture. He stands tall. Camera lenses love that.

Is Mason Thames Still Growing?
At 19, he is near the end of the typical male growth window. Most young men stop gaining meaningful height between 18 and 21, once their growth plates fuse. Some minor change is still biologically possible. Another dramatic spurt is not.
The visible change now will come from build, not inches. Action roles demand muscle. His upcoming part in Caine, the John Wick universe spin-off starring Donnie Yen, will likely require serious physical training. Expect a broader Mason Thames in the next few years. Do not expect a much taller one.
Mason Thames Age
Mason Thames was born on July 10, 2007, in Dallas, Texas. He turned 19 years old in July 2026. His zodiac sign is Cancer.
His age is the remarkable part of his story. He carried a major horror film before he could drive. He anchored a live-action blockbuster at 17. He led three No. 1 box office debuts in a single year at 18. Most actors wait a decade for that kind of run. He did it while finishing high school.
He belongs to the same generation of young screen talent as Corey Mylchreest, the Queen Charlotte breakout. Both went from near-unknown to leading-man status in their late teens. Both carry franchises on young shoulders. That is a lot of pressure for 19. Thames has handled it with unusual calm.

Early Life, Family, and Ballet Years
Mason Thames grew up in McKinney, Texas, part of the Dallas–Fort Worth suburbs. He attended school in nearby Prosper. His childhood was about as far from Hollywood as you can get.
His path into performance started with dance, not acting. His older sister Brooke-Madison Thames was a trained ballerina. Mason followed her into dance classes. He stuck with it for about four years. He toured with a professional ballet company as its youngest member. He performed in productions of The Nutcracker.
That training shaped everything. Ballet teaches body control, timing, stillness, and discipline. You can see it in his work. Watch him in The Black Phone and notice how little he wastes. Every movement is precise. Horror directors notice that economy of motion. Scott Derrickson, who directed the film, has praised Thames’s ability to process emotion truthfully without overacting. He called it a gift that cannot be taught.
His parents supported both the ballet years and the shift into acting. He grew up watching action and adventure movies with his father, films like The Avengers and Pacific Rim. Those movie nights planted the seed. A home movie fan from Texas became, a decade later, a blockbuster leading man.
Mason Thames Career: From Horror Breakout to Hiccup
Thames made his acting debut in the 2017 short film After Omelas. Small start. Then came a recurring role in the first season of the Apple TV+ series For All Mankind in 2019. Three episodes of prestige television. Good schooling for a young actor.
He also appeared as a younger version of Cordell Walker in the CW series Walker across its first two seasons. Television taught him sets, schedules, and professionalism. Film would teach him everything else.
The Black Phone Changed Everything
The Black Phone premiered in 2021 and went wide in 2022. Thames played Finney Blake, a shy 13-year-old abducted by a sadistic kidnapper (Ethan Hawke) and locked in a soundproof basement. A disconnected phone on the wall starts ringing. The killer’s dead victims call through it. They help Finney plan his escape.
The role was brutally competitive. Hundreds of young actors auditioned. Derrickson chose Thames for his emotional honesty. The film grossed over $160 million worldwide. Critics singled out the young lead. The industry took notice. Horror fans had a new name.
Thames returned as Finney in Black Phone 2 in October 2025. The sequel brought back Ethan Hawke, Madeleine McGraw, and Jeremy Davies. It completed the arc that started when Thames was a child actor. This time he played it as a young adult.
Hiccup and How to Train Your Dragon
The biggest bet of his career came in June 2025. Universal Pictures released the live-action remake of How to Train Your Dragon, directed by Dean DeBlois. Thames played Hiccup Horrendous Haddock III. Nico Parker played Astrid. Gerard Butler returned as Stoick.
Carrying a beloved franchise is dangerous work. Fans protect these characters fiercely. Thames pulled it off. The film was a major commercial success. He reportedly earned a Saturn Award nomination for the role. A sequel, How to Train Your Dragon 2, is expected in 2027. He is set to return.
The role suited his physical profile perfectly. Hiccup is the clever underdog who grows into a leader. A lean, athletic, slightly-above-average frame sells that arc without any camera tricks. His Mason Thames height of around 5’10” puts him right in the sweet spot for an action-adventure lead: tall enough to look capable, average enough to stay relatable.
Regretting You and the 2025 Box Office Run
October 2025 brought a sharp left turn. Regretting You, the Josh Boone-directed adaptation of Colleen Hoover’s novel, cast Thames as the romantic lead Miller Adams. He starred opposite McKenna Grace, Allison Williams, and Dave Franco.
One entertainment outlet noted something remarkable about his 2025: three separate No. 1 box office debuts in a single year, spanning fantasy, romance, and horror. The last actor to do that was Jim Carrey in 1994. Whether or not you love box office statistics, the range is real. Three genres. Three leading roles. One year.
Between those tentpoles, he also headlined the 2024 Netflix comedy Incoming and starred in David Henrie’s indie horror-adventure Monster Summer alongside Mel Gibson. Genre-hopping is deliberate. After The Black Phone, he has said, the industry tried to set him on a serious, dark route. He pushed back toward variety instead.
What Is Mason Thames Doing Next?
His 2026 slate stayed busy. He starred as Tommy in Nimrods, the road comedy about a band racing to open for Green Day, which opened in August 2026. The same month brought Idiots, an R-rated comedy. Both expanded his comedy credentials.
Looking ahead, three projects stand out. Narcs, a coming-of-age comedy at Sony Pictures directed by John Phillips, was announced in September 2026. Caine, the John Wick universe spin-off led by Donnie Yen, puts Thames into big-league action territory. And How to Train Your Dragon 2 is expected in 2027. The franchise work continues.
Mason Thames Girlfriend: Relationship Status
Mason Thames keeps his dating life private. He has not confirmed any public relationship. He does not discuss romance in interviews. He has no confirmed girlfriend as of 2026.
Some gossip blogs have linked him with Regretting You co-star McKenna Grace during their 2025 press tour. Those reports remain unconfirmed. Neither actor has publicly addressed them. Red carpet chemistry is part of the job, and fans should not read a relationship into it without real evidence.
This is worth stating plainly because he is 19. He is a young adult, and speculation about his private life serves nobody. His public image is built on craft, not celebrity relationships. The honest answer to the Mason Thames girlfriend question is: he has not said, and it is his business.
Mason Thames Net Worth: What the Estimates Say
Published estimates of Mason Thames net worth in 2026 range from about $1 million to $4 million. Most biography sources cluster in the $1 million to $2 million range. One newer profile estimates around $4 million.
Those numbers deserve context. No major financial publication has published a verified figure for him. Every number online is an estimate built from public career information. None comes from a confirmed financial statement. Treat any exact figure with healthy skepticism.
His income streams are straightforward. Lead film salaries are the core. Studio franchises pay well, and he has carried three of them. Television work (For All Mankind, Walker) paid early-career fees. Endorsements are the growing stream. His appearances at luxury fashion events, including a noted Louis Vuitton moment, signal that brand partnerships are becoming serious money. Social media adds a smaller layer on top.
The How to Train Your Dragon franchise is the engine. Blockbuster leads renegotiate upward with each sequel. With a second film expected in 2027 and franchise options beyond, his earning power is still climbing. Profiles of similarly positioned young actors, like Vina Sky, show the same pattern: private income forces every figure to be an educated guess. The trajectory matters more than the exact number, and his trajectory points up.

Public Image and Lifestyle
For someone this visible, Mason Thames runs a remarkably quiet public life. He is active on social media, where fans get behind-the-scenes glimpses of film work. He avoids the manufactured celebrity persona that surrounds many young stars. Interviews keep returning to the same theme: craft over image.
Directors and co-stars consistently praise his focus. Scott Derrickson has spoken about his honesty on camera. Press coverage of the How to Train Your Dragon tour emphasized his professionalism. He shows up, does the work, and goes home.
He still reads as the Texas kid who grew up loving movies. That grounded quality is part of his casting appeal. Audiences believe him as the underdog. Studios trust him with franchises. The combination is rare, and it is why his name keeps appearing on shortlists for the biggest young-lead roles in Hollywood.

Conclusion
The Mason Thames height question has a simple honest answer and a complicated explanation. The simple answer: he is widely reported to stand 5 feet 10 inches tall. The complicated part is everything around it. Teenage growth, conflicting old profiles, photo angles, and red carpet heels have turned one number into a permanent internet debate. Treat any site claiming absolute certainty with caution. The range of 5’8″ to 5’10” is the truthful version, with 5’10” the most cited figure.
His height is only a footnote to the real story. A Texas ballet kid carried a horror film at 14, anchored a fantasy blockbuster at 17, and stacked three No. 1 debuts at 18. That run took range, discipline, and a work ethic his directors keep praising in public. The inches never mattered. The performances did.
You can read his full documented biography on Wikipedia. News of his upcoming work, including the Sony Pictures comedy Narcs, was reported by FemaleFirst, relaying the Deadline casting story. With a second trip to Berk on the way, the most interesting chapters of his career are still ahead.
