Hi Cherie, I believe that commercially anklets are 9 inches long but
I have had to make some up to 10 1/2 inches for women with a more
ample leg definition. As to where it sits, On the inside of your
ankle you will find a bump which is part of the larger leg bone
called the tibia. This part of the tibia is called the malleolus, and
I make the anklet the required length to hang just below the center
line of this .
Hope this helps,
