Thigh Circumference (Left & Right)

Track leg muscle development and detect bilateral asymmetry.

Equipment

Flexible tape measure.

The protocol
  1. 01Client stands with weight evenly distributed on both legs.
  2. 02Measure at the midpoint of the thigh, halfway between the inguinal fold (groin crease) and the proximal border of the patella (top of kneecap).
  3. 03Keep tape horizontal. Measure both legs.
  4. 04Record to nearest 0.1 cm.
What to watch for
  • Client shifting weight to one leg.
  • Inconsistent measurement point — use the midpoint consistently.
  • Asymmetry >5% may warrant investigation.
How to read the result

No pass/fail standard — compare to the client's own history and between legs. A side-to-side gap above ~5% is worth investigating.
