Size Guide
Every Selene piece lists its exact size on the product page. This guide is here for when you are between sizes or buying a gift.
Ring sizes
All our rings use the US sizing standard.
| US size | Inside diameter | Inside circumference |
|---|---|---|
| 4 | 14.9 mm | 46.8 mm |
| 5 | 15.7 mm | 49.3 mm |
| 6 | 16.5 mm | 51.9 mm |
| 7 | 17.3 mm | 54.4 mm |
| 8 | 18.1 mm | 57.0 mm |
| 9 | 18.9 mm | 59.5 mm |
Method 1: measure a ring you already own
- Pick a ring that fits the finger you have in mind.
- Lay it flat and measure straight across the inside, from edge to edge, in millimetres.
- Match that number to the inside diameter column above.
Method 2: measure your finger
- Cut a strip of paper or a piece of string about 10 cm long.
- Wrap it around the base of the finger. Snug, but loose enough to slide over your knuckle.
- Mark where the end overlaps, lay it flat and measure the length in millimetres.
- Match that number to the inside circumference column above.
A few things worth knowing. Fingers are slightly larger at the end of the day and in warm weather, so measure then rather than first thing in the morning. If your knuckle is much wider than the base of your finger, go up half a size. And if you land exactly between two sizes, size up: a ring that spins a little is easier to live with than one that will not come off.
Necklace lengths
Most of our chains come with an extender, so you can wear the same piece at two lengths. The product page lists the exact length and extender for each one.
| Length | Inches | Where it sits |
|---|---|---|
| 40 cm | 16" | Choker. Sits close around the base of the neck. |
| 45 cm | 18" | The most common length. Sits on the collarbone. |
| 50 cm | 20" | Just below the collarbone. Good as a second layer. |
| 55 cm | 22" | Mid chest. Works as the longest piece in a stack. |
If you are layering, leave about 5 cm between each chain so they sit apart instead of tangling.
Bracelets and anklets
Our bracelets and anklets are adjustable and come with an extender chain, so one size fits most wrists and ankles. To check, wrap a strip of paper around your wrist just below the wrist bone and measure it flat. Add roughly 1.5 cm for a comfortable fit.
Earrings
Hoop sizes are listed as a diameter on each product page. As a rough guide, anything under 15 mm reads as a small everyday hoop or huggie, 15 to 30 mm is a mid-size hoop, and above 30 mm is a statement hoop.
