Reference charts
Reference tables of estimated lean body mass by height, weight, and sex — computed with the Boer equation, with James and Hume comparisons on every detail page. Use them to see where you stand, then get a personal estimate with the calculator.
Find your height row and weight column below for a quick Boer-formula estimate in pounds. For the full picture — kilograms, the James and Hume comparisons, lean mass percentage, and realistic ranges for your exact height or weight — open the matching detail chart further down.
These are population-average estimates. For a personal number that uses your measured body fat percentage, use the main lean mass calculator or the body fat calculator first.

Each height chart shows lean mass estimates across the full realistic weight range for that height, in both pounds and kilograms.
Each weight chart answers “how much of that weight is lean mass?” across realistic heights for that weight.
Most healthy adult men carry roughly 75-90% of their body weight as lean mass and most women roughly 68-85%, because women carry more essential fat. The absolute number scales with height and weight, which is what these charts show.
Every value is computed with the published Boer (1984), James (1976), and Hume (1966) equations from height, weight, and sex. Implausible height-weight combinations (BMI below about 17 or above about 40) are excluded because the formulas were not fit on those ranges.
No. Height-weight formulas describe population averages. If you know your body fat percentage from DEXA, calipers, or a consistent smart scale, lean mass = weight × (1 − body fat ÷ 100) is more accurate for you personally.
Lean mass drives your calorie burn at rest, anchors protein targets, and tells you whether a diet is costing you muscle. Tracking it beats tracking scale weight alone.
