Sizes in mm

Every size, in millimeters.

Small earrings are hard to judge from a photo. So every size in the store is a measurement, with a plain translation beside it.

Open hoops: the top and the drop.

TopDropOpeningWire
Top
The width of the piece that sits in front of your lobe.
Drop
The distance from the piercing to the bottom of the curve.
Opening
The gap at the front, between the top and the end of the curve.
Wire
How thick the wire is.

One piece, front to back: the top sits in front, the wire curves under the lobe, and there is no separate back.

Once our calipers and scale have measured the samples, every open hoop's page lists its top, its drop, its opening, its wire and the weight of the pair, each in millimeters or grams, each with a plain translation.

How it sits:

Where the hoop sits depends on how far your piercing is from the edge of the lobe. Here is how to measure it.

How to measure your piercing

You need a millimeter ruler and a mirror. A second person helps.

  1. Find your piercing. Hold the ruler flat against the front of your lobe, with zero at the center of the piercing.
  2. Read the distance straight down to the edge of your lobe. Write it down in millimeters.
  3. Do the same for each piercing you want to fill. Each one can be different.

Each open hoop's page gives its drop in millimeters once our calipers have measured it.

Huggies: inside and outside.

A hinged huggie. The closure is built into the hoop.

Once our calipers have measured the samples, each huggie's page gives its inside size, with the outside beside it.

The inside is the space your lobe passes through. The outside, the number we call "across", is how big it looks on your ear.

How to match a huggie you already own:

Lay it flat on a ruler. Read across the outside, edge to edge, and match that number to the "across" size on our huggie's page once our calipers have measured it.

How it sits:

Where a huggie sits depends on how far your piercing is from the edge of the lobe. Measure it the same way as for an open hoop.

A set holds more than one piece, so its page gives a size line for each piece, in ear order, lowest piercing first.

The dime table.

A dime is 17.91 mm across, 1.35 mm thick and weighs 2.268 g (US Mint). Every translation in the store comes from this table.

Where a product page shows a maker's figure, it says so: "Factory-stated until our calipers confirm." We replace it with our own measurement once our calipers have measured the piece.
