Mason Thames Height Explained: Real Stats & Facts

How tall is Mason Thames? It’s a fair question. On screen, the actor can look lanky in one scene and small beside a 6-foot-2 Viking in the next. Fans have debated it since The Black Phone, and the argument only grew after he played Hiccup in How to Train Your Dragon (2025). The short answer: Mason Thames is most often listed at 5 feet 8 inches (173 cm). That number is an estimate, not an official stat. Here’s what the evidence actually shows.

Mason Thames Height at a Glance

Want the quick version? This table sums up the public details, and it marks anything unconfirmed as such.

The last row matters most. Thames hasn’t posted a height on his social media or shared one in a major interview. So every figure you see online is an educated guess.

How Tall Is Mason Thames in Feet and Centimeters?

Most sources land on 5 feet 8 inches, or about 173 cm. CelebHeights, a site that tracks celebrity height estimates, lists him at 5 feet 8 inches (172.7 cm). Some entertainment sites shave an inch off and say 5 feet 7 inches (about 170 cm).

Here’s an easy conversion table if you want the Mason Thames height in cm and in feet side by side.

So what’s the safest answer? Mason Thames is likely somewhere between 5’7″ and 5’8″. If a friend asks, say “around 5’8″” and leave it there. You’ll be close to right either way.

Why Do Websites Give Different Numbers for Mason Thames’ Height?

Ever searched for his height and seen three different answers in the first five results? You’re not imagining it. Some pages claim he’s 5’3″. Others say 4’11”. A few swing the other way and insist he’s 5’11” or even 5’10”.

Those outliers don’t hold up. A listing of 4’11” would make him shorter than most young teens, and he clearly isn’t. A 5’11” claim would put him level with Ethan Hawke, his co-star in The Black Phone, yet side-by-side photos show Hawke standing noticeably taller. Many of these pages also contradict each other about his birth year and birthplace, which tells you how little checking went into them.

Three things cause most of the confusion:

• No official stat. Without a number from Thames or his team, sites fill the gap with guesses.
• Age changes. He started acting as a kid. Early listings may reflect his height at 12 or 13, and teens grow fast.
• Copycat content. One wrong number gets copied from site to site until it looks like fact.

The takeaway is simple. Treat any single figure with caution, and look for the range where credible estimates overlap.

Who Is Mason Thames?

Before we dig deeper into height, a little background helps. If you landed here after watching him in a dragon movie or a horror film, you might wonder how old he is and where he came from.

Mason Thames was born on July 10, 2007, which makes him 19 as of October 2026. His name is pronounced “thaymz.” Wikipedia lists Dallas, Texas as his birthplace, though a couple of other databases say Phoenix, Arizona, so the exact answer isn’t settled across the web.

Early Life and Start in Acting

Thames made his acting debut in 2017, when he was about 10. His early credits include a guest part on the series For All Mankind in 2019, where he played Daniel Stevens, and a young version of the title character in the TV series Walker. These were small parts, but they gave him a start on professional sets.

He was a toddler when the original animated How to Train Your Dragon came out. Reports say he later dressed up as Hiccup around age seven. That detail made his later casting feel like a full-circle moment.

Breakout With The Black Phone

His big break came with The Black Phone, a horror film directed by Scott Derrickson. Thames played Finney Blake, a teen kidnapped by a masked killer, opposite Ethan Hawke. The movie reached theaters in June 2022 and earned more than $160 million worldwide on a small budget. Thames earned a Saturn Award nomination for Best Younger Actor in a Film for the role.

He returned as Finney in Black Phone 2 in October 2025.

Hiccup and a Big 2025

In 2025, Thames landed his biggest part so far: Hiccup Horrendous Haddock III in Universal’s live-action How to Train Your Dragon, directed by Dean DeBlois. Gerard Butler returned as Stoick the Vast, and Nico Parker played Astrid. Thames picked up another Saturn Award nomination for the role.

That same year, he starred as Miller Adams in Regretting You, based on the Colleen Hoover novel. A sequel, How to Train Your Dragon 2, is scheduled for 2027, and Thames is set to return as Hiccup.

How Does Mason Thames’ Height Compare to Other People?

A number alone doesn’t mean much. Is 5’8″ short? Tall? Average? Context makes the answer clearer.

Mason Thames vs. the Average American Man

The average adult man in the United States stands about 5 feet 9 inches (roughly 69 inches), according to CDC data. At 5’8″, Thames sits about an inch below average. That’s well within the normal range. Most men fall somewhere between 5’6″ and 6’0″, so he’d blend into a crowd without anyone noticing.

If the lower estimate of 5’7″ is closer to the truth, he’d be about two inches under average. Still normal.

Mason Thames vs. His Co-Stars

This is where the debate heats up. Co-stars like Gerard Butler, who is commonly listed at 6 feet 2 inches, tower over most people. Standing next to Butler, almost any actor would look small, and that’s exactly the point of Hiccup and Stoick’s relationship. The father is a giant. The son is the odd one out.

Ethan Hawke is usually listed at around 5 feet 11 inches. Fan comparisons of photos from The Black Phone press events suggest Thames stands several inches shorter, though posture and shoes can shift that gap. Remember that photo comparisons are rough tools. A bent knee or a heel can change the picture by an inch or more.

Mason Thames vs. Other Young Actors

Here’s a fun comparison. Tom Holland is commonly listed at 5 feet 8 inches, which matches the most common Thames estimate. Tom Cruise is usually listed at 5 feet 7 inches, matching the lower estimate. Both men lead huge films, and nobody asks them to stand on a box.

Keep in mind that celebrity heights are often rounded or adjusted, so treat this table as a rough guide, not a lab measurement.

Does Mason Thames’ Height Affect His Roles?

Short answer: not much. Hollywood cares about height less than people think, especially for a lead who can act.

Hiccup is written as a skinny, awkward teen who doesn’t fit the Viking mold. Thames’ lean build and average height actually work well for that. Pair him with a 6’2″ Butler and the size gap tells the story without a single line of dialogue. Directors also use camera angles, lens choices, and set design to make actors look taller or smaller. A character can seem “tiny” in one frame and heroic in the next.

In The Black Phone, Finney is a quiet kid who fights to survive. His height doesn’t matter there either. What sells the role is how he handles fear, and critics praised that performance.

For romantic leads like Miller in Regretting You, a 5’8″ actor fits comfortably. Plenty of leading men sit in that range, and casting directors usually care more about chemistry between co-stars than a few inches.

Is Mason Thames Still Growing?

He’s 19, so it’s possible but not likely by much. Most guys reach their full adult height by about 18 or 19, and some add a little more into their early twenties. If Thames hasn’t been measured recently, he might already be at his final height.

Genetics play the biggest part. Nutrition, sleep, and overall health during the teen years also matter. Some websites claim to predict his “future height,” but nobody outside his family and doctor can say. Unless he shares a new number, assume he’s close to where he’ll stay.

What About Mason Thames’ Weight and Build?

His weight hasn’t been shared publicly, and it’s best not to trust sites that print an exact number. What you can see on screen is a lean, slim build. Reports mention a background in dance and stage work, and that kind of training often leads to good posture. That posture can make an actor look taller on camera than he is in person.

Fans often point out his longer neck and slim frame, which can create a tall impression in solo shots. Put him next to a bigger co-star and the effect disappears fast.

How to Judge a Celebrity’s Height Without Getting Fooled

Since Thames’ height is an estimate, here’s how to sort good info from bad when you read about any star:

1. Check the source. An interview, a red-carpet comparison with a person of known height, or a direct statement from the actor beats a random listing.
2. Look for ranges. If several credible sites say 5’7″ to 5’8″, that’s more trustworthy than one site claiming exactly 5’11”.
3. Watch the date. A listing from when he was 13 won’t match his height at 19.
4. Be careful with photos. Heels, posture, camera angle, and lens distance all change how tall someone looks.
5. Ignore wild outliers. If one page says 4’11” and ten others say around 5’8″, the outlier is almost always wrong.

Use these steps and you’ll spot most bad height claims fast.
