Muscle Proportions Calculator.

[Big Jake]

Is there a calculator that can calculate the proper proportions for each muscle in the body if you give it the total body's ideal height and weight?

No, but I can give you some pretty good rules of thumb, depending on how built you want someone to be. For example:

Arnold had a 57-inch chest at 240 lbs. Sean Allan, at 340 lbs., has had a chest measurement as much as 68 inches. When I'm calculating (fantasy) measurements, I tend to put chest (in inches) at somewhere between 2% and 2.5% of total bodyweight (in lbs.)

Likewise, for arms. Arnold's were 22 1/2 inches at 240 lbs. (9.375% of bodyweight.) More typical, perhaps, is Will Harris, who is said to have had 25 inch arms at 300 lbs. (8 1/3%) On the other hand, Robby Robinson (way back in the day) had arms measuring 21 1/2 inches at probably no more than 215 lbs. (10%) So I usually pick a number somewhere between 8-10% of total weight (in lbs.)

The rest is pretty easy because (a) waist oughta be about 50% of chest; (b) quads ought to be the same size as waist; (c) calves and neck ought to be the same size as biceps.

So, for your typical fantasy 6 ft 400 lb. bodybuilder, the following stats might obtain:

Chest: 80 inches
Waist: 40 inches
Biceps: 32 inches
Quads: 40 inches
Neck / Calves (32 +/- 1-2 inches depending on which part you wanted to have out of proportion to the rest.)

Hope this helps! :-)

Here's a link to the Ideal Proportion Chart that"s floated around the net for some years now. It's pretty easy to expand it to ratios for "fantasy" guys too.

For example, Richard's fantasy guy's ratio is 5.56. The numbers he give are quite close to what the chart would predict.

I also found this calculator for Macro-stat making, it might help: Macro Stat
