Find out what the ideal measurements are for a natural bodybuilder or a classical muscular male physique.

I’m often asked what my body measurements are and/or what are the ideal measurements for a bodybuilder or a classical muscular male physique. Believe it or not, there are actually many formulas for determining the “ideal body proportions.” On the other hand, you might want to take them with a grain of salt…

QUESTION: Tom, there is one thing that I really would like to know – your measurements. You have a physique that (in my opinion) is ideal and your photos are a real inspiration to me. I am able to move up in weight gradually with my workouts, so I know I am building muscle, but I never have a measurement to shoot for – e.g. biceps, chest, waist, hips, etc. Also, it seems like certain ratios (for example, chest to waist ratio, and maybe there are others?), would be helpful also. My thinking is that if my waist and hips are “growing” faster than my chest, then that might be an indicator that I am gaining fat where it likes to show up first (hips and waist). The measurements I have of myself are: chest, waist, hips, biceps, forearms, thighs, calves. Thank you.

ANSWER: Personally, I no longer take my measurements, although I did regularly when I was a teenager. I do, however think it’s a great way to chart progress. Circumference measurements give you feedback about how well your training (and nutrition) regimen are working and let’s you catch yourself if certain body parts are lagging behind others, or in the case of waist and hips, if you’re gaining body fat.

The waist measurement is an important one, because when your waist circumference is going down, you know your overall body fat is going down. Also, when your waist shrinks even a little bit, it tends to completely change the way you look – even if you don’t gain any muscle, a narrow waist (also see ab exercises) creates an illusion of broader shoulders (also see shoulder exercises). Abdominal fat and a large waist measurement is also a health risk.

There have been all kinds of different formulas proposed over the years for the “ideal proportions”, but I never aimed for a certain measurement myself. Bodybuilding is a very visual sport. The judges don’t come up on stage and measure your arms in a bodybuilding contest – you are judged on appearance.

I’ve always gone after a certain “look” as opposed to a certain measurement. I cut out photos of bodybuilders whose physiques I admire and want to emulate and rather than having a measurement in mind, I always have a picture of my ideal in mind.

On top of a solid base of muscle size, I simply work towards symmetry, so all muscles are developed equally, with no single muscle groups that are out of proportion compared to others - for example, a huge chest and rib cage with small arms looks silly - huge arms and small legs looks un-symmetrical as well.

I’m not all that hung up on weighing a certain amount either, although I do weigh myself regularly. The main reason I monitor my weight closely is because in the off season, I’m always interested in gaining more lean body mass and prior to competition I have to make a weight class (middleweight has a 176 1/4 lbs cutoff. )

I’m 5’ 8” tall and I weigh 174-176 for competitions. That is very much a “false” weight, however, because I easily lose 6-10 pounds of water weight in the three days before a contest. By the Monday after a Saturday contest, my weight is usually back up to 180-184 or so. Off season, I weigh about 195-200 lbs. My off season body fat is usually around 9-10% and before contests it’s around 4%.

Years ago I do remember measuring my arms and they were 17 1/2” cold and 18” pumped. That was a long time ago. I would imagine they’re bit larger now, but who knows. My waist is 31-32” most of the year, even smaller before contests (last notch on the lifting belt!)

These are somewhat typical off season / pre contest height, weight and body fat measurements for a natural bodybuilder. In the professional and open federations (not drug tested), those weights and measurements might be considered “small.” However, a 17-18 inch arm on a lean and proportionate body can look very impressive.

Steve Reeves for example, was known as one of the most symmetrical and aesthetically pleasing bodybuilders of all time, even though he was not “huge” by today’s standards.

Reeves wrote about ideal measurements frequently and was always striving for his idea of perfection in this regard (and came close to achieving his own personal ideal). One of his criteria for ideal proportions included having his arms, calves and neck measure the same.

  • Arms: 18.5 inches
  • Calves: 18.5 inches
  • Neck: 18.5 inches
  • Thighs: 27 inches
  • Chest: 54 inches
  • Waist: 30 inches

In his “classic physique” book, Reeves said his formula for “ideal proportions” was as follows:

Muscle to bone ratios:

  • Arm size = 252% of wrist size
  • Calf size = 192% of ankle size
  • Neck Size = 79% of head size
  • Chest Size = 148% of pelvis size
  • Waist size = 86% of pelvis size
  • Thigh size = 175% of knee size

Steve Reeves’ height and weight chart for a bodybuilder (natural)

Height Ideal Weight Height Ideal Weight
5’5” 160lbs 6’0” 200lbs
5’6” 165lbs 6’1” 210lbs
5’7” 170lbs 6’2” 220lbs
5’8” 175lbs 6’3” 230lbs
5’9” 180lbs 6’4” 240lbs
5’10” 185lbs 6’5” 250lbs
5’11” 190lbs

In the book Brawn, Stuart McRobert published the old “John McCallum formula for “challenging yet realistic” measurements for “hard gainers". His formula is based on wrist measurement and was also published in the book Super Squats:

John McCallum’s realistic measurement ideals for hard gainers

  1. 6.5 times your wrist gives chest girth
  2. 85% of the chest girth produces the hips
  3. Take 70% of the chest girth for the waist
  4. 53% of the chest gives the thigh girth
  5. The neck size is 37% of the chest
  6. 36% of the chest produces the upper arm girth
  7. The calves come out a little less at 34%
  8. The forearms get 29% of the chest measurement

Incidentally, McRobert’s book Brawn has an entire chapter called “expectations” which discusses the truth about measurement claims.

I find all these measurement ideals very interesting, but personally I take them with a grain of salt.

Be careful with some of the formulas for “ideal measurements”, because if they were based on steroid using and or pro bodybuilders, you may get discouraged by trying to pursue an impossible goal for a natural bodybuilder or the measurements of someone with a totally different bone structure than you have.

Measurements - especially arm measurements - are also frequently exaggerated. Twenty inch arms, for example, are rare and when you actually see them in person, you realize just how massive they really are. But somehow beginners and natural athletes get the idea in their head that bodybuilding success means 250 pounds and a 20 inch arm.

The truth is, a 17 to 18 inch arm on a ripped 175-180 pound physique with excellent balance, symmetry and proportion can look much larger than it really is – it’s an optical illusion of sorts.

Some of these guidelines for “ideal proportions” are the “Grecian” or “classical” ideals while others are ideals for bodybuilders. In either case, keep in mind they are subjective – they’re just someone else’s opinion of what is an ideal measurement. The only opinion that matters in the end is your own.

Train hard and expect success,

hello. im 6ft 1, 169 pounds. i want to compete in a physique competition and am looking for some advice as to what measurements i need to have in order to compete.

Posted on: Sat, 04/24/2021 - 10:59

This article will give you some ideas based off of your wrist size, but if you're going by height, if you're 73 inches tall, you should try to get your waist to about 32.5 inches, or .447 times your height. If you'd like your shoulders to match that, according to the golden ratio of 1.618, they'd need to be about 52.5 inches. I've found other articles that suggest your chest should be about 1.4 times your waist, so that would be about 45 inches, and your arms should be half your waist, so 16.52 inches. Your hips should be your chest divided by 1.1, so 40 inches, and your legs should be your hips divided by 1.65, so 24 inches, according to other articles I've found. Your calves can match your arms.

If you go by this article, John McCallum's formula for your ideal waist size gives you a 7.17-inch wrist and his recommendations are:
Chest 46.605
Hips 39.61425
Waist 32.6235
Thigh 24.70065
Neck 17.24385
Upper arm 16.7778
Calves 15.8457
Forearms 13.51545

You're not necessarily going to need these exact measurements to compete, but keeping everything in proportion is key. As you diet down, your waist will shrink, and you can hopefully maintain size in your shoulders, chest, etc. Men’s physique is all bout a narrow waist, so if your waist is less than 32.5 inches, keep it there and work on developing wide shoulders, lats, chest, etc. Proportion, and knowing how to pose to present your physique is more important than hitting exact measurement targets.

I am a 45 year old truck driver and bodybuilder/power lifter . I have boxed/martial arts and lifted weights for over 30 years. The problem I have is the two year physical for my dot card to drive a truck. They say I am obese. I have hardly any fat, I am 5'8 at 205 lbs. I have 17.5 inch arms, 46 inch chest, 34 inch waist. They are wanting me to loose weight. From where I asked??? I bench 500lbs I told them. I am not going to starve myself and stop lifting weights. I have been at this weight for twenty years. These weight to hight scales do not include weight lifters. So they would consider the 25 year Arnold, Lee Haney, Dorian Yates obese? Really?

hi please tell me your opinions and tips. i'm 5'7 14.5 inch arms, chest is 38cm , waist 28cm , neck is 13.3. i'm only 136lbs i don't have a decent lower body, do you think it's somehow okay to compete in a novice natural physique ocmpetition with these numbers?

Great measurements for your size...esp the chest/waist/legs ratio. If you get your conditioning 'stage ready,' you would do well in a NATURAL novice men's physique contest.

I'm 6ft 16st and my m8 is 15st
He is in better shape in all fairness and seems to be a lot bigger .
I just don't get how I can be a stone heavier.
But look smaller
If muscle is supposed to be heavier than fat.
Could it be body dismorphia?
But I do feel thin. But obviously im not because the scales say im over weight.
Anybody else feels this way. Especially if I've skipped meals.'s like I can loose weight real fast .It's horrible
Cheers guys

Posted on: Sat, 01/09/2021 - 04:31

Is it very simple to explain , when someone is leaner he looks way bigger when naked because the muscles are more exposed and not covered by the fat. Someone looks way smaller NAKED with higher body fat. When dressed the leaner guy tends to look smaller though.

Hi im 5.8 my neck is 13.5. biceps 10.5 chest 32. Waist size 28.5
I wanted to know how much should i train to get my ideal physique what my measurements should be?

Posted on: Tue, 05/28/2019 - 17:11

It isn't always about how much to train, what is the most important is caloric intake. You should be consuming a lot more calories than you are right now. Around 5-7 meals of smaller portions is ideal. You will notice strength and muscle gains with eating more combined with working out, rather than solely working out without proper nutrition.

One before losing weight we all know were going tonput off water weight first.You weigh yourself certain times if the day your going to weigh more or less.Best time to weigh is when you first wake up up.But the same goes on measurements do it all first thing in the morning ehen you wake up then you will know your accurate readings.

Well, I'm about 212 at 5'9, but I'm trying to get to about 200lbs. I'm all natural, and the 180lbs that Reeves mentioned would seem tiny to me! I think it all depends on body type. I'm endomorphic, so my body is naturally heavier, whether I like it or not!

Posted on: Thu, 09/17/2015 - 01:20

Hahahahah What stupid faggots! If I weighed 81 kilos at 5'9" I'd be overweight, not ideal. Crazy meathead with their pseudo bullshit.

Posted on: Fri, 07/09/2021 - 10:21

No, that's still lean. Even a doctor will tell you the same. BMI is entirely useless for athletic people because muscle is far more dense. At 185 5'10.5 I actually feel incredibly lean, and I'm around 10% body fat and can move around decently enough in size 30 pants. I can still stretch and move as agilely as any 145lb guy.

hey people. As ashok mentioned his question, i got one too. i m 5'6" n m 58 kgs only. what should my ideal weight be and what are my ideal chest and arms size supposed to be?

Posted on: Tue, 02/16/2021 - 20:27

Your ideal weight should be 72 kg with 38 cm chest and 16 inchs biceps it gives you a heavy bodybuilder look

Posted on: Tue, 07/15/2014 - 05:58

In order for this to make any sense, the measurments need to be described as a girth (side to side measurement) or a circumference. A waist girth of 30 inches is pretty big (and possibly dangerous for heart disease), whereas a cirumference of 30 inches is slim.

really nat?
Posted on: Tue, 10/28/2014 - 12:06

Actually Nat, girth and circumference have the same meaning. I'm sure it was just a slight over sight on your part. Now Width means a measurement from side to side. Maybe that's the one syllable word you were looking for?

I am 67 years old. Do fitness and strength training twice a week for 1 hour each time. Have done this for little over 2 years. 5 foot 11 inches tall. My calves are 15-5/8 inch. Good BMI. Are they average-good-or better?
Upper body strength very good.

Posted on: Sat, 03/31/2012 - 11:37

Is the upper arm measurement meant to be taken with the bicep flexed or relaxed? It makes a big difference.

Good post about ideal measurements. I do have to say that I feel the Steve Reeves chest measurement is off. I have seen many other places where it was listed at 52", and many more that listed it at 50 inches. I really think he had a 50" chest, which is great and would match the rest of his measurements better. I always thought Bob Paris had some of the best symmetry and proportion around, but I could never find his measurements listed anywhere. He had a lot of the Reeves lines though, something we're not seeing much of today.

Posted on: Fri, 07/28/2017 - 18:13

Yea and his arms neck and calves we're nowhere near 18.5 when he was lean lol

hi. my name is andrew and i struggle with a little bit of stomach fat. i have a bad addiction to red bulls. im tryin to quit but its hard. i was wonder if u knew if i can still drink one or two and still be able too loose weight and build muscle?

Posted on: Sat, 05/05/2012 - 22:08

Dude, its pure sugar. Sugar = bad carbs. Bad carbs = fat. You can gain muscle depending on what you're eating and how you're working out in the gym, but as far as fat goes, good luck if you're going to keep drinking Red Bulls. In short, cut your addiction and choose something healthier as a substitute for sugar, like fruit. Or if it's the caffine you're addicted to, drink coffee.
