Over the years I’ve often wondered how do my overall measurements compare to the average guy – specifically my arms (I know how my weight compares). As I probably stated before, I’ve always wanted to get my arms to 18″ (flexed, cold) and always seem to fall just short of my goal. Yeah, sometimes life just works out that way.
Size Matters
Now 18″ sure seems a reasonable size when you read about pro bodybuilders with 20, 21, or even 22″ arms. Granted, the pros are more than likely exaggerating their size to maintain a certain mystique, maintain their ego, and even to “psyche” out the competition. Also, their size is very likely beyond the normal, non-chemically enhanced person. There are also experts, such as Ellington Darden – one of my favorite workout “gurus” of the eighties, who say that because of improper measuring almost all arm sizes are exaggerated (especially with a cloth tape which can add a quarter of an inch to the circumference because of the width of the tape itself).
What is Average?
Anyway, finding out the stats on the average male arm was tougher than I thought! There are several articles and discussions on the web and they mostly point back to the same one or two sources – Men’s Health magazine among them – and the answer seems to be that an American man of 5’9.5″ at a body weight of 175 has arms which are 13″ in circumference. What I can’t find is if that’s a flexed or unflexed measurement. My guess is unflexed since 13″ seems a bit on the small side to me for a flexed arm of a fully grown man, but I could be wrong.
Now granted I’m a little taller and a lot heavier than the so-called “average” man I’ve referred to above, but in any case my arms are significantly larger than 13″ even unflexed (about 14.75″ unflexed – 16 flexed as of this morning). I, of course, don’t think my arms look that big, but I imagine that’s common among those of us who workout to get both bigger and stronger, and hanging around gyms and guys who workout does mean that I tend to be around people who are, on average, larger than average. Heck, my former training partner’s arms taped at around 18″ and I’ve compared myself to him for years – even when his arms where “only” about 16″ and mine where in that average neighborhood of 13″ (was I really that “small” once?).
My Experience and Opinion
My own personal obsession with big arms, and bodybuilding in general, was probably strengthened when I was first diagnosed with Crohn’s and my weight dropped to below 140 lbs and my arms shrank to 11″ (flexed! – I was literally skin and bones at that point).
However, all the above are just statistics. I think ultimately, a man’s arm is considered big simply when it looks big. I know men who are relatively short (below 5’10”) and have arms that appear massive (Google any male gymnastic team). But in reality, they don’t tape over 16″. Likewise, there are tall men (6′ or more) who appear thin, but their arms tape at over 17″ (think basketball players). Perspective plays a big role in appearance. That along with bodyfat percentage and muscle shape (see examples below).
To Sum it Up
Keep lifting, watch your diet so that your bodyfat stays low and ignore the tape. You’ll be surprised at how big your arms look. If you want to find out how big you are compared to other lifters and “recreational” bodybuilders check out my blog post How Do My Arms Stack Up to Other Gym Bros and participate in my survey to add to the data I’ve collected on this topic.
Oh, and wear shirts one size smaller than you usually do. That’s the fastest way to get big arms. But for the secret to building big arms (which isn’t a secret) check out my post on the subject here.
I’m curious as to what other people think. When do you think an arm is “big?” And I, of course, mean in a solid, muscular way.
Onward!
NOTE: In September 2018 I researched average arm size again and found that 13″ still appears to be the standard for a 20 – 29 year old man. However, this number moves closer to 14″ in middle age (50+) presumably due to an increase in body fat however, not an increase in muscle mass. The 13″ arm is also based on a man of average height (in the USA about 5’9″. No doubt taller men may have naturally larger arms and there’s always that one guy out there who never trains but has the arms of a Mountain Gorilla anyway).
P.S. Do you wonder when a man’s chest is considered big? Check out my blog on that subject HERE!
