um, i’m not sure the reason, but i dont think thats it. From the people i know with peyos behind the ear, its until about the bottom of the ear, where its attached to the head, not the lobe. and from that length and on. One of my relatives doesnt cut his peyos but is not chassidish to curl them, and doesnt either tuck them under his kippa, but wraps them around his ears. Just saw him recently- must be 10 inches long
