Classic Proportions Reference

Work out the circumferences that Steve Reeves' muscle-to-bone ratios give for your wrist, ankle, knee and hip measurements. These are one bodybuilder's aesthetic preferences from the 1950s — not a health standard, and not a judgement of your body.

What this page is

These are the aesthetic preferences of one man, Steve Reeves, put forward in the 1950s. They are not a health standard, not a medical measure, and not training advice from this site. Matching these numbers will not make you healthier, and not matching them means nothing.

This page calculates without judging: it gives you the numbers the formula produces. It does not ask for your own measurements, does not compare, does not score, and never tells you how far off you are.

Everything is computed in your browser: nothing is uploaded, nothing is stored, no AI is involved.

Measure four bony sites

These ratios are anchored to skeletal size — measure at the narrowest point near the bone, not the muscle. Keep the tape against the skin without pulling it tight. Centimetres.

cm

Narrowest point, clear of the wrist bone

cm

Narrowest point of the ankle

cm

Across the middle of the kneecap, leg straight and relaxed

cm

Around the widest part of the hips (pelvis)

cm

Around the largest part, just above the eyebrows

Fill in at least one field. A field you leave blank is simply not calculated — no default is substituted.

How this is calculated, and where it comes from

How this is calculated, and where it comes from

Nothing here is invented. The six ratios are copied from the source; the arithmetic is simply base circumference × percentage, rounded to one decimal place.

How far the sourcing was verified

Two independent sources quote these figures, agreeing word for word on all six, and both attribute them to the book above. But neither gives a page number, and we do not have the book itself. So, precisely: what we verified is that two independent sources consistently attribute these figures to that book — not that we checked the book's own text. Please read the results with that in mind.

Why we don't ask for your own measurements

Once you enter them, a comparison is unavoidable, and a comparison is a judgement about your body. This site does not judge physiques — pose reviews comment on the pose itself, nothing else. So this page simply does not accept your own measurements.

About the neck ratio

"Neck = 79% of head" needs a head measurement, which few people take in a gym setting. Head circumference is therefore optional: leave it blank and you just don't get the neck figure; the other five are unaffected.
