Let's start with the lever-back clasp which is about 9/16" long. So the earring bauble starts roughly 1/2" from the earhole.
The smallest of my earrings drops down roughly 3/4" and the largest on the site is about 2".
I have not put measurements up on many of the items, but am happy to answer questions, send additional pictures, and to try items on during a Zoom meeting.
