Wrist & Ankle Measurement Guide
Accurate measurement of wrist and ankle circumference for the Genetic Muscle Mass Limit calculator
These two measurements determine your bone structure and frame size. Use a flexible measuring tape and measure bare skin without compressing the tissue.
Measure at the narrowest point of the wrist β just distal to the styloid processes of the radius and ulna.
Measure at the narrowest point of the ankle β just above the malleoli. The tape goes above the bones, not through them.
Common Mistakes to Avoid
Always measure bare skin β fabric adds thickness and distorts the reading.
Keep the tape perfectly horizontal and parallel to the floor for both measurements.
The tape should be snug β touching the skin all around β but not indenting it.
Wrist: narrowest point below the wrist joint. Ankle: narrowest point above the ankle bones, not through them.
