His shoes on NCIS look pretty thick at least 1 1/4 to 1 1/2 inch soles, his height is about 5'11.5 and with the extra thick soles on his shoes can look like a 6 footer.

Bruce willis was an inch taller than Harmon on moonlighting and his peak is down at 182cm so Harmon could not of been 6ft.

Pause at 0:04. The guy pointing the gun, Paul Telfer, is listed here at 6ft1 (but I think could be slightly more). There's way more than 1in between him and Harmon, more like 3in! But maybe Paul has bigger shoes. I think Harmon is maybe a bit under 6ft today and Telfer is just over 6ft1. There could potentially be a full 2in difference

I was living in Los Angeles in 96 and gassed my car at the same time as Mark. I'm almost exactly 6'1" and he wasnt much shorter, seemed like almost 6, maybe 5'11"&1/2

@grizz I think he's more 5' 10½" now, he looked 2 inches taller than Jon Cryer on NCIS this past week, I don't think he was 6'0 in his prime, probably 5'11

looks like brad is not reliable.

@Dave, it might be possible that he lost a bit of height. He's almost 65 after all.
He might be a strong 5'11 these days.
Dave said on 22/Oct/15
He didn't look 6ft on the late late show with 5ft10 Drew Carey, Mark was 1-2 cm tallr.

Harmon was one of the shortest quarterbacks in the Pac 8 Conference, when he played in the early seventies. He was listed at 6'0" on the UCLA roster. It is the norm for players to be listed at heights 1 or 2 inches taller than they actually are. Harmon was more than likely 5'10.5".

Definitely a solid inch or more taller than 6'0 Allison Janney on the West Wing, including shots where their footwear was visible.

I was on the MCIS set four years ago when I lost on Jeopardy...and I got to stand nearby with the- then- cast with "Ziva"...Weatherly and Murray were about 6'2"...quite tall. Harmon was a bit shorter, so Ill say at least 6'...
jtm said on 1/Jan/15
that's funny brad. i rememeber 6'0 was your estimate in the past.
Brad said on 31/Dec/14
5' 10" 30 years ago when I met him.

I do know that Mark Harmon was an outstanding quarterback at UCLA and won several awards for his play. I think he had to be 6 feet tall!

@Editor Rob - I agree about those shows! Ted Danson and Elisabeth Shue have brought much needed life to CSI, unlike boring Grissom! Although I liked Airwolf and Quantum Leap, I still think Donald Bellisario's best show was the one he did with Glen Larson - Magnum, p.i. No repetitive formulas, but actual stories about people!
In fairness to Mark Harmon, he does have good posture, considering he was an American Football player. His joints could have been wasted by now!

He looks it in The West Wing next to Allison Janney.
said on 4/Oct/14
I just don't believe he's 6ft. He never looks it. I think it's just palaver spread around by all the NCIS groupies who worship his character like a God - like all the other characters in that repetitive formula show do!
David McCallum (the Scottish guy!) is the only one in it worth watching!
[Editor Rob: shows like NCIS/CSI, after 3-4 years you need to have your brain wiped...but on the show I think he generally can still look near 6ft]
grizz said on 6/Aug/14
Is he really 6ft? He doesn't seem that tall in NCIS. He seems to be 181-182 now, guy who plays Palmer in NCIS is a legit 6ft and he's always taller than Harmon.
MarcoH said on 4/Jul/14
I also think he was 182cm (5'11.5) in his prime, today in his 60s he is at 180-181cm (5'11).
Stranger said on 3/Nov/13
No way he is 183, i met him in freaky friday premier, i am 180 and i he was between 179 and 180
Chris said on 29/Oct/13
If I remember correctly, Bruce Willis had a good 2-3 inches on him in Moonlighting. Bruce is listed as 5'11". So, I gotta say Harmon is due for a downgrade. He's 5'9" to 5'10" tops.
Rampage(-_-_-)Clover said on 22/Sep/13
Could be 5ft11.5/182cm now
Marissa said on 2/Apr/13
I've stood near him a bunch of times and don't think he is any taller than 5'10", probably 6 ft in his pre-middle age height.
Rampage(-_-_-)Clover said on 30/Oct/12
Can look 184cm

He's 60 now and I think he was definitely 6ft (1.83 m) at his peak, but he might be just below or 182 cm now.
Chad said on 29/Jan/12
Parrette is a strong 5´9" rather than a flat 5´10", Harmon is over 5´11" for sure, maybe even 6ft, but never over, 5´11.5" is my best guess.

me live in pakistan my age is 24 and my height is 5f5 inches i want to increase my height up to 6feet

My Marine is 6'4" & the one I dated before him
was 6'6". Most folks consider them tall. My Marine
dad was 6'3" & his Marine brother was 6'2".
For their time (WWII)- pretty darn tall!
k mart said on 3/Nov/11
mark is def a solid 6' or 1.84 meters tall.. he probablys 6' 1/2'' and just rounds down and says 6'... most tall guys dont bother using the 1/2 inch!
i am 6'2'' and some change but i just say solid 6'2''. it is just easier!! :)
Alex said on 30/Jun/11
cris - Pauley Perrette - 'the strange girl' is 5'10", and she does wear heels, so Harmon being 6'0" - easily believable

Hey, jj.. You WERE a marine ? Did you forget that they told you at bootcamp ?!?! wtf
Once a marine...
Steve said on 10/Apr/11
iam laughing about the rumor that marines arent tall. thats not true...
Adam said on 2/Apr/11
Funny, watching NCIS I always thought he was 5'9-5'10 because he was shorter than most of the other male actors. I guess most actors are just really tall.
jj said on 12/Mar/11
My dad was a Marine---6'0" Chosin. I was a Marine---6'2" Grenada and first gulf war, my nephew is a Marine 6'1" Iraq-one tour and two tours Afghanistan. Harmon played at UCLA til 1974 Program there listed him at 6'. Just for the record

Found his signature character later in his career as Leroy Jethro Gibbs in NCIS. He's a classic example of a 6'0" man. Too small to play at quarterback in pro football.
Saw him recently in 1988's THE PRESIDIO with co-star Sean Connery. Connery has been listed at 6'2"--a measurement I believe to be correct--and Harmon looked to be 2" shorter than Connery, with both men wearing similar footwear.
6'0" is spot on for Harmon. Michael Weatherly, too, looks to have just about 2" on Harmon--Weatherly being listed at about 6'2".
Yo said on 3/Mar/11
184-185 cm for sure!
67 inch tall lady in IN said on 13/Feb/11
First people are just curious about height. Second don't be rediculous about he has to be short to be a marine. My father was a marine and he was 6' 2" and lastly Abby aka strange girl in black usually seems to have on 6" heels.
Army Vet said on 24/Dec/10
He's to tall to play a Marine, ever notice that Marines aren't very tall. Big things come in small packages, I have nothing but the highest respect for the Corps.
said on 8/May/07
Found a photo of myself with him at a Coors promo thing in '86. He's 6' dead on. One of the nicest people to meet.
[Editor Rob: always looks like one of those legit 6 footers, I like that NCIS, watch that more than CSI]
MHouillon said on 7/Jun/06
Okay, Weatherly is a little taller than that. I'd say Dinozzo is a 187cm candidate.
MHouillon said on 25/Jun/05
Yeah, Mark Harmon is 6'0". His NCIS co-part Michael Weatherly (Tony Dinozzo) is 6'1" and looks clearly just an inch taller than Mark "Leroy Jethro Gibbs" Harmon.
