How to read this male chart
This chart shows estimated lean body mass for a man who is 6'4" (193 cm) tall, across realistic body weights. Each row is computed with the three standard height-weight equations — Boer, James, and Hume — plus the lean mass percentage implied by the Boer result.
As a reference point, a 230 lb man at 6'4" has an estimated lean body mass of about 164.9 lb (74.8 kg) by the Boer equation — roughly 72% of body weight. Within the commonly cited healthy-weight window for this height, Boer lean mass falls between about 138.2 lb (62.7 kg) and 154.9 lb (70.3 kg).
For a personal estimate that also accounts for your body fat percentage, use the main lean mass calculator — the direct body-fat method beats every formula below.

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 for a 6'4" Man
What is the lean body mass of a 230 lb man at 6'4"?
Using the Boer equation, a 6'4", 230 lb man has an estimated lean body mass of about 164.9 lb (74.8 kg), which is roughly 72% of total body weight. A measured body fat percentage gives a more accurate personal answer.
What is a good lean body mass for a 6'4" man?
Within the healthy-weight range for 6'4", Boer estimates fall between roughly 138.2 lb (62.7 kg) and 154.9 lb (70.3 kg). Trained men typically sit above the formula estimate because the equations assume average muscularity.
Which formula in this chart should I trust?
Boer is the most widely validated for healthy adults and is the default on this site. James and Hume are shown for comparison; if the three disagree a lot for your weight, that is a sign to measure body fat and use the direct method instead.
