How To Measure Earring Length. One carat total weight diamond stud earrings will feature two 050 carat diamonds. For stud earrings which contain a drop we measure the width of the setting and the drop together.
Measure the thickness of the earring or plug with a caliper. We measure all our earrings from where the earring hooks onto your ear to the end of the drop. But with post earrings I measure from the bottom of the post.
Measure your neck size.
So with hook I hook the earring over the ruler. 14 gauge 16mm. 20 gauge 08mm. While this chart serves as a great starting point the best way to get an accurate picture of how large your hoops will be is to break out your ruler and use it as a reference.
