Choose hoop size by checking whether the listed diameter is measured inside or outside the ring, then compare it with a hoop that already fits the way you want. Inner diameter describes the available space; outer diameter describes the overall silhouette. They are not interchangeable.
Start here
A photograph can help you judge style, but it cannot tell you how the same hoop will sit on a differently placed piercing. Start with a measurement reference, then decide whether you want a close or more open look.
Find out what the size label measures
Cords Club's Essential Hoops listing explicitly describes its options as interior diameters. That is useful wording: it tells you which space to compare rather than leaving you to guess from the number.
Another listing may describe an outer diameter or omit the convention. If it is unclear, ask the seller. A thicker ring can have a larger outside measurement without providing the extra inside space you expected.
| Measurement | Helps answer | Does not answer |
|---|---|---|
| Inner diameter | How much open space is inside the hoop? | Will it suit every piercing placement? |
| Outer diameter | How large is the overall outline? | Is the wearable opening the same as another hoop? |
| Post gauge | How thick is the wearable post? | How far below the lobe will it hang? |

Compare jewelry, not two model photographs
If you own a hoop you like, note its model and listed inner diameter. Use it as your reference for the same piercing. Decide whether your next pair should sit similarly or look more open.
For a style preview, draw the proposed outer outline on paper beside that familiar hoop. This can help you visualize scale, but it is not a wearable fitting test. Do not assume a circle held beside your ear reproduces the position of a real hinge, post and piercing.
Also consider width and decoration. A thick plain ring and a narrow ring with a drop can look very different despite sharing an inner diameter. Compare the complete outline rather than buying by diameter alone.
Huggie is a style description, not your size
Treat a close-fitting look as a preference to discuss, not an instruction to buy the smallest option. Maria Tash's sizing guide explains hoop choice in terms of how closely you want it to sit. That preference still needs to work with your placement.
If you have no suitable reference, an in-person fitting is more useful than ordering several very small hoops and hoping one closes. For a new or healing piercing, use your piercer's guidance rather than this shopping comparison.

Choose the base hoop before adding charms
A charm changes the look of the entire earring, so establish that the plain hoop works for you first. Then check the charm's compatibility with the exact model and size. A charm that suits one diameter in a range may not suit every version.
If you are deciding between a hoop and a stud, first read our earring shopping guide. The Cords Club guide is a starting point for browsing once your size and preferred style are clear.
