How to read this male chart
This chart shows how much of a 230 lb (104.3 kg) body weight is estimated to be lean mass for men, depending on height. Height matters because at the same weight, a taller person carries more bone and muscle and less fat on average — so every row below gives a different answer.
As a reference point, a 230 lb man at 6'0" has an estimated lean body mass of about 158.9 lb (72.1 kg) by the Boer equation — roughly 69% of body weight.
If you know your body fat percentage, you do not need this table: lean mass at 230 lb is simply 230 × (1 − body fat ÷ 100). At 20% body fat that is 184.0 lb (83.5 kg); at 30% it is 161.0 lb (73.0 kg).

Limitations of these male estimates
Boer, James, and Hume estimate lean body mass from height, weight, and sex alone. They describe population averages, so a very muscular or very lean person will be underestimated and a person with above-average body fat will be overestimated.
If you know your body fat percentage from a DEXA scan, calipers, or a consistent smart scale, skip the formulas: lean mass = weight × (1 − body fat ÷ 100). That direct method is more accurate than any height-weight equation.
The lean mass percentage column uses the Boer estimate, the most widely validated equation for healthy adults. Values are estimates for tracking and nutrition planning, not a medical diagnosis.
FAQs: Lean Body Mass at 230 Pounds (Male)
How much lean mass does a 230 lb man have?
It depends on height. By the Boer equation, estimates range from about 147.0 lb (66.7 kg) at 5'4" to about 170.9 lb (77.5 kg) at 6'8".
Is 230 lb a healthy weight?
That depends on height and body composition, not weight alone. 230 lb spans a healthy BMI for some heights in this chart and not for others — and a muscular man can be perfectly healthy at a BMI that looks high on paper. Body fat percentage is the better check.
Why do the three formulas disagree?
Boer, James, and Hume were each fit on different study populations. James in particular drifts at higher body weights, which is why this site defaults to Boer. Large disagreement is a cue to measure body fat and use the direct method.
