Aidan Gallagher Height — How Tall Is the Umbrella Academy Star?
Aidan Gallagher is approximately 5 feet 8 inches tall (173 cm).
His height changed during his teen years, and the figure above reflects his adult height based on recent appearances, not the smaller measurements that circulated when he was a younger teen.
That said, it’s worth noting upfront that several long-running databases still list him shorter (more on why that happens below).
Aidan Gallagher’s Current Height
As of today, the most widely repeated “current height” for Aidan Gallagher in newer bios and fan-facing explainers is:
Height (feet & inches): ~5’8”
Height (centimeters): ~173 cm
Is he fully grown?
Gallagher was born in 2003, and most men have completed the majority of height growth by the late teens. So, for practical purposes, he’s considered fully grown at this point.
Aidan Gallagher Height Over the Years
One big reason “aidan gallagher height” search results look messy is that his most famous role (Five on The Umbrella Academy) began when he was still a teenager—and he visibly grew while the show was ongoing.
What fans saw on-screen (and why it matters)
Early seasons (around 2019): He appears significantly shorter than most adult co-stars—partly because he was younger, and partly because he’s often framed beside much taller cast members.
Visible growth window (roughly 2019–2022): Across press events and later-season appearances, he looks noticeably taller than in early promo cycles—consistent with late-teen growth patterns.
Now (adult height): Newer profiles increasingly repeat ~5’8” (173 cm) as his current height, reflecting his “grown” look in recent years.
Why older numbers still circulate
Major databases and height sites often keep a static height that was added years ago—sometimes when an actor was still a teen. For example, IMDb still lists Aidan Gallagher at 5’5” (1.65 m), which likely reflects an older entry from earlier in his career.
How Tall Is Aidan Gallagher Compared to Co-Stars?
Aidan’s height can look different depending on who he’s standing next to—because The Umbrella Academy cast includes some very tall actors.
Here are commonly listed heights for key co-stars:
Tom Hopper (Luther): 6’5” (1.96 m)
David Castañeda (Diego): 5’11¼” (1.81 m)
Robert Sheehan (Klaus): 6’0” (1.83 m)
Emmy Raver-Lampman (Allison): IMDb lists 5’8” (1.73 m)
Elliot Page (Viktor): IMDb lists 5’1” (1.55 m)
Justin H. Min (Ben): IMDb lists 5’11” (1.80 m)
What that means for Aidan on camera
If Aidan is ~5’8”, he’ll read as:
About the same height as Emmy Raver-Lampman on paper (depending on shoes/angles).
Much shorter than Tom Hopper (a huge contrast that makes Aidan look smaller even if he’s average-height).
Compared to the average man
The CDC’s measured average height for U.S. adult men is 68.9 inches (about 5’9”). That puts a ~5’8” Aidan just a touch under the U.S. average—basically in the “average range.”
Comparisons to Similar Personalities
Fans also search comparisons to other well-known figures. Here are commonly listed heights from widely referenced databases and major entertainment coverage:
iShowSpeed: IMDb lists 5’9” (1.75 m). (So he’s roughly 1 inch taller than a ~5’8” Aidan.)
Kevin Hart: Hart has publicly clarified his height as 5’5” in sneakers in a 60 Minutes interview recap covered by major outlets. (Aidan would be about 3 inches taller.)
Tom Holland: IMDb lists 5’6” (1.69 m), even though some pop-culture articles often repeat 5’8”. Using IMDb’s figure, Aidan would be about 2 inches taller.
Kendrick Lamar: IMDb lists 5’5” (1.65 m). (Aidan would be about 3 inches taller.)
Quick takeaway: If you picture Aidan at ~5’8”, he’s in the same general zone as a lot of “not super tall, not short” celebrities—while still looking smaller next to towering co-stars like Tom Hopper.
Why Aidan Gallagher’s Height Is Often Misreported
If you’ve seen anything from 5’2” to 5’7” (or even a locked-in 5’5”)—you’re not alone. Here’s why it happens:
The child-actor effect
Aidan became famous while still young. Early stats get copied everywhere, then “stick,” even after someone grows.Static database listings
Big databases can keep older details for years. Example: IMDb still lists him at 5’5” (1.65 m).Outdated bios and reposts
Many entertainment sites recycle older profiles. Even more careful outlets have historically described him as falling in a range (like 5’5”–5’7”) rather than updating to a single adult figure.Camera tricks + footwear
Premiere shoes/boots, posture, and who he’s standing beside can shift how tall he looks in photos.

About 5’8” (173 cm) as his commonly cited current/adult height in newer bios and recent-era coverage.
Did Aidan Gallagher grow taller?
Yes—he visibly grew from his early teen years into his late teens/early 20s, which is why older height numbers often don’t match what fans see in later seasons and recent appearances.
How tall was Aidan Gallagher in Season 1?
Season 1 debuted in 2019, when he was still a teen and looked notably shorter than most adult co-stars—so many early listings pegged him shorter than today. (This is also why some databases still show an older figure like 5’5”.)

Conclusion
If you’re searching how tall is Aidan Gallagher, the most up-to-date answer fans are looking for is: around 5’8” (173 cm)—and the key context is that his height changed during his teen years, especially across the period when The Umbrella Academy made him a household name.
That’s why SERPs can feel outdated: older entries (including major databases) still reflect earlier measurements, even though his more recent, adult-era appearances point to a taller, settled height today.
