Locate the top of your hipbone (pelvic crest) on the side of your body. (Note: the pelvic crest slopes down at the front – but we are interested in the location of the highest point of your pelvis).
Approximate the top of your hipbone in your lumbar region, on your spine. Wrap the tape measure horizontally from the top of your hipbone to the spine to confirm this position if required. Make a note of this location.
Locate your C7 vertebrae. This is the highest bony protrusion on the back of your neck and is roughly in line with where your trapezius meets your neck. Make a note of this location.
Measure the length between your C7 vertebrae and the location you found on your lumbar spine in step 2.
