Who Is Mason Thames?
Mason Thames is an American actor born on July 10, 2007, in Dallas, Texas, and raised in McKinney, Texas, where he attended school in Prosper, Texas.

His screen debut came in the 2017 short film After Omelas. By 2022 he was starring opposite Ethan Hawke in a globally distributed horror film, and by 2025 he was leading one of the highest-grossing fantasy franchises in cinema history.
Mason Thames Height: The Real Answer

Mason Thames stands at 5 feet 8 inches tall (173 cm). That figure comes from appearance-based estimates from industry sources. Some outlets have published figures ranging from 5’7″ to 5’10”, which is typical for a young actor whose height was still changing through his mid-teens. As of 2026, those measurements have stabilised. The 5’8″ figure is the one to rely on.

Why Mason Thames Height Gets So Much Attention
Height becomes a frequently searched topic for young actors because fans track physical development alongside career development. Mason Thames draws particular attention for three reasons.
First, his co-star in The Black Phone was Ethan Hawke, who stands around 6 feet. The contrast between them on screen, deliberately amplified by cinematography designed to make Mason’s character Finney feel small and trapped, created a lasting impression that he was significantly shorter than he actually is.
Second, Mason was still actively growing during his peak early fame. Fans who found him in 2022 and compared photos from 2024 and 2025 could see visible physical changes, which generated ongoing curiosity about where his height landed.
Third, his How to Train Your Dragon success in 2025 brought a massive new global audience to his name. That wave of new fans searched his basic stats, and height is always among the first questions a new audience asks about a young star.
How Mason Thames Height Compares
The 5’8″ figure places Mason in a height range shared by some of Hollywood’s most commercially successful leading men:
| Actor | Height | Notable Franchise |
|---|---|---|
| Mason Thames | 5 ft 8 in (173 cm) | How to Train Your Dragon, The Black Phone |
| Tom Holland | 5 ft 8 in (173 cm) | Spider-Man |
| Tom Cruise | 5 ft 7 in (170 cm) | Mission: Impossible |
| Timothée Chalamet | 5 ft 10 in (178 cm) | Dune |
| Ethan Hawke (Black Phone co-star) | 6 ft 0 in (183 cm) | Various |
The comparison with Tom Holland is particularly relevant because both actors broke through as teenagers in blockbuster franchises and both operate in the 5’8″ range that casting directors consider versatile for leading roles across action, romance, and drama.
Mason Thames Age and Birthday

Mason Thames was born on July 10, 2007, making him 18 years old in 2026. He celebrated his 18th birthday in July 2025, the same summer How to Train Your Dragon was released. That timing made his birthday widely covered across entertainment media.
He is a Cancer by zodiac sign. He grew up in McKinney, Texas, in Collin County, where he balanced school at Prosper with an acting career that began before most of his classmates had their first jobs. He was named to Forbes’ 30 Under 30 in Hollywood and Entertainment in 2025, the youngest person on the list.
Mason Thames Parents

Mason Thames’ parents are Byron Thames (father) and Lisa Alpart (mother). Byron is also an actor and was the parent who most directly fuelled Mason’s love of film. He took a young Mason to movie screenings regularly, introducing him to films like The Avengers and Pacific Rim that fired his imagination and planted the goal of working in cinema.
Mason has described his childhood in McKinney as creatively rich but grounded. His family supported both his ballet training and his eventual transition to acting without pushing him in either direction. That environment of encouraged ambition without manufactured pressure is something he has acknowledged in multiple interviews as central to how he approaches his career.
Much like other performers whose family environment shaped a disciplined artistic identity from an early age, his parents gave him both the exposure and the space to find his own path.

Mason Thames Sister and Ballet Background
Mason’s older sister Brooke-Madison Thames is a professional ballerina and the person directly responsible for one of the most important aspects of his physical presence on screen. Mason began studying ballet alongside Brooke from age 5, trained for four years, and toured with a professional international ballet company as its youngest cast member, performing in productions including The Nutcracker.
That training gave him things that most young actors spend years trying to develop: precise physical control, spatial awareness, posture that reads as commanding on camera, and intentional movement in every scene. Directors notice. Casting directors notice. Audiences sense it without being able to articulate why he seems more physically mature than his age suggests.
His ballet background is the single most underreported fact about Mason Thames height perception. At 5’8″, he appears taller on screen than the measurement suggests, and that gap between real height and perceived height comes almost entirely from four years of professional dance training.
Mason Thames Career
Short Film and Television (2017-2021)
Mason Thames made his acting debut in the 2017 short film After Omelas at age 10. His television debut followed in 2019 with a role in Apple TV+’s For All Mankind, playing young Danny Stevens. He also appeared in the CW series Walker between 2021 and 2022, building his resume across both drama and science fiction before his feature film breakthrough.
The Black Phone (2022)
The Black Phone, directed by Scott Derrickson and based on a Joe Hill short story, became Mason’s breakout film. He starred as Finney Blake, a 13-year-old abducted by a serial killer known as The Grabber, played by Ethan Hawke. The film grossed over $161 million worldwide on a relatively modest budget and earned significant critical attention for Mason’s performance.
The cinematography was deliberately constructed to make Finney appear small and vulnerable. Tight frames, low-angle shots, and Hawke’s physically imposing presence all emphasised Mason’s comparative smallness on screen. That was artistically intentional and thematically effective, but it also created the widespread impression that his real-world height was significantly shorter than it actually is.
How to Train Your Dragon and 2025 Breakthrough
Director Dean DeBlois cast Mason as Hiccup Horrendous Haddock III in the live-action How to Train Your Dragon (2025) after watching his work in The Black Phone. The role was a childhood dream for Mason, who had dressed as Hiccup for Halloween years before being cast.
“I never thought that I’d be given the chance to step into his shoes and maybe affect kids the way Hiccup affected me,” Mason told The Hollywood Reporter in June 2025.
His three 2025 releases, How to Train Your Dragon, The Black Phone 2, and Regretting You, each debuted at number one in North America. The collective $790 million global gross tied Jim Carrey’s 1994 record for an actor leading three consecutive number-one releases. He received a Saturn Award nomination for HTTYD and was named to Forbes’ 30 Under 30 in Hollywood and Entertainment as the youngest person on the 2025 list.

Mason Thames Net Worth
Mason Thames net worth is estimated at $1 million to $2 million in 2026. His income comes from acting fees across major studio productions, brand partnerships including his appearance at the Louis Vuitton Paris fashion show in June 2025, and endorsement interest that has grown significantly following his 2025 box office performance.
His salary for How to Train Your Dragon is estimated to have reached six figures, standard for a lead role in a major studio fantasy production. As his profile continues to grow, his net worth is positioned to increase substantially through the second half of his teens and into his twenties.
Will Mason Thames Get Taller?
At 18, Mason Thames is at or very close to his full adult height. Most males stabilise in height between ages 17 and 21, with any further growth typically measuring less than an inch. Based on his current verified measurements and growth trajectory visible across appearances from 2022 to 2026, his height has settled around 5’8″.
The more meaningful question for his career is not whether he will grow taller but whether his physical presence will continue to develop as he transitions from teen roles to adult ones. The signs are strong. His ballet-trained posture, lean build, and increasingly mature on-screen confidence suggest a performer whose perceived stature will keep growing regardless of what the tape measure says.
