Size Guide: Rings, Bracelets & Necklaces
A few minutes to measure, and never an unwelcome surprise again. Here's how to find your exact size — with simple methods, size charts, and a little calculator to guide you.

Before you start
Three small habits that make all the difference, whatever the piece:
- Measure at the end of the day. Fingers and wrists swell slightly with warmth and activity — that's when your measurement is most accurate.
- Avoid the cold. We shrink in cold weather: a ring measured when your hands are chilly will be too tight the rest of the time.
- Grab the right tool. A soft tape measure, or simply a strip of paper and a ruler. That's all you need.
The right mindset: better to measure twice than order wrong once. And if you're still unsure after this guide, write to me before you order — I'm always happy to help.
Finding your ring size
Ring sizes here use the standard US scale. To find yours, you'll take one quick measurement — from a ring that already fits, or from your finger directly — and match it to the chart below. Two ways to do it:
Take a ring that already fits the right finger. Measure its inside diameter (edge to edge) in inches with a ruler, then match it to the chart below. This is the most reliable method.
Wrap a thin strip of paper around the base of your finger, without pulling tight. Mark where it overlaps, unroll it, and measure the length in inches: that's your finger's circumference. Match it to the chart to read your US size.
Find your measurement here (inside measurements are approximate):
| US size | Inside diameter | Inside circumference |
|---|---|---|
| 4 | 0.58 in | 1.83 in |
| 4.5 | 0.60 in | 1.88 in |
| 5 | 0.62 in | 1.94 in |
| 5.5 | 0.63 in | 1.99 in |
| 6 | 0.65 in | 2.04 in |
| 6.5 | 0.67 in | 2.09 in |
| 7 | 0.68 in | 2.14 in |
| 7.5 | 0.70 in | 2.19 in |
| 8 | 0.71 in | 2.24 in |
| 8.5 | 0.73 in | 2.29 in |
| 9 | 0.75 in | 2.35 in |
| 9.5 | 0.76 in | 2.40 in |
| 10 | 0.78 in | 2.45 in |
Or let the calculator do the work for you:

Bracelet type:
Tip: measure the exact finger that will wear the ring — sizes vary from finger to finger, and your dominant hand is often a little larger. Also account for your knuckle: if it's prominent, measure it too, since the ring has to slide over it.
Finding your bracelet size
It all starts with your wrist circumference. Wrap a tape measure (or a strip of paper) around your wrist, just below the wrist bone, without pulling tight. Note the measurement in inches: that's your starting point.
Then you add a little ease depending on the bracelet type — this is where many people go wrong:
| Wrist | Beads on elastic | Flexible, with clasp |
|---|---|---|
| 5.5 in | 6–6.25 in | 6.25–6.5 in |
| 6 in | 6.5–6.75 in | 6.75–7 in |
| 6.5 in | 7–7.25 in | 7.25–7.5 in |
| 7 in | 7.5–7.75 in | 7.75–8 in |
| 7.5 in | 8–8.25 in | 8.25–8.5 in |
| 8 in | 8.5–8.75 in | 8.75–9 in |
- Beads on elastic: add about ½ to ¾ in to your wrist. Elastic stretches, so this style is the most forgiving.
- Flexible with clasp: add about ¾ to 1 in so the bracelet drapes nicely without squeezing.
- Rigid bangle: not measured at the wrist but at the widest part of your hand, fist closed — that's what it has to slide over.
Good news
Most of my obsidian bracelets are strung on elastic cord: they adapt to a small range of sizes, which clearly reduces the risk of getting it wrong. If you're torn between two, go with the larger one.
Choosing a necklace length
A necklace doesn't have a "size" but a length, which determines where it falls on your chest. Best method: take a piece of string, hold it around your neck at the height you want in front of a mirror, then measure it flat. Compare with this guide (lengths in inches):
The choker (14–14.5 in), worn snug around the neck, rounds out the family for those who love the look.
Good to know: many of my necklaces have an adjustable extender chain that lets you fine-tune the length by an inch or two. Enough to perfect the drape for any outfit — and one more safeguard against choosing the wrong length.
Between two sizes: what to do
It happens often, and it's no problem. Here's the simple rule:
- Ring: size up. A slightly loose ring can be fixed (a sizing insert, or I can adjust it); a ring that's too tight simply can't be worn.
- Bracelet: size up here too, especially for a clasp style. On elastic, the built-in ease does the rest.
- Necklace: when in doubt, choose the longer length — a slightly longer necklace always works, and extender styles can be shortened.
And the best option of all: write to me before you order. Send me your measurement and the piece you love, and I'll confirm the ideal size. It's free, and it's exactly what I'm here for.
