Frequently Asked Questions
Why does frame size matter?
It provides useful context for interpreting ideal weight and BMI numbers, since a larger frame naturally carries more healthy weight.
Where should I measure my wrist?
Measure around the narrowest point of your wrist, just below the wrist bone, for the most consistent result.
