Earring Back Sizes



In order to ensure a secure fit, it is important to match the gauge of the ear nut to the gauge of the ear post. Keep in mind that the higher the gauge number, the thinner the post will be.

Measure the widest part of the threaded portion of the earring post. Use a digital gauge/caliper in order to obtain accurate results.

      • 21 GAUGE = .71MM = .028" (Typical of baby or toddler earrings)
      • 20 GAUGE = .82MM = .032" (Thinner posts, common on less expensive earrings)
      • 19 GAUGE = .90MM = .0375" (Available in push-on-screw-off styles)
      • 18 GAUGE = 1.0MM = .040"(Thicker posts, typical of more expensive earrings)

Simply screw the back to the threaded earring post post with a turning motion - much more secure than a push-on back! To put on a screw back earring, after aligning the holes of the back with the post behind your ear lobe, hold the earring back firm in one hand and turn the earring from the front. That is easier to maneuver, and it avoids your hair becoming twisted into the back of the earring.

Our replacement earring backs are die-struck, as opposed to cast. Die striking is a process of jewelry manufacturing that uses an immense amount of pressure to form precious metal into a desired shape producing a product with a higher gold content, and of superior strength and durability. Cast jewelry uses a low-pressure mold method of making jewelry that results in a lower quality item.

We are committed to the quality you deserve!
