Welcome to a transformative journey of self-discovery through our Lean Body Mass Calculator. Unveil your body’s story.

The following calculator gives you an estimate of your % bodyfat and lean body mass based on your weight, height, age and simple tape measurements (i.e. anthropometric measurements).

Skin-fold measurements alone tend to underestimate body fat percentage in the obese [1] and very lean (particularly with low hydration levels).

The following calculator is based on equations [2, 3] which are useful for people in these groups as well as people with loose skin after very large weight losses.

It is generally accurate to within a few percent. Anecdotally, it has also proven to be reasonably accurate with drug-free, genetically typical bodybuilders.

What is Lean Body Mass?

Lean Body Mass (LBM) refers to the weight of everything in your body except fat. It includes muscles, bones, organs, and other non-fat tissues. LBM is a crucial indicator of your body’s composition, reflecting overall health and fitness.

As you aim for a healthier lifestyle, understanding and optimizing your lean body mass can guide your fitness goals, ensuring a balance between muscle development and fat management. Achieving a favorable Lean Body Mass contributes to enhanced metabolism, strength, and overall well-being.
