Find Your Perfect Size
Simple steps, clear pictures. If you get stuck, just ask us.
One chart for everyone
Most women wear 4–8, most men wear 8–14 — but hands don't read labels. Measure yours.
US ring sizes run on a single scale for everyone, measured by the inside diameter of the band. We craft in half sizes from US 3 to 15; quarter sizes are available on request.
| US Size | Inside Diameter | US Size | Inside Diameter |
|---|---|---|---|
| 3 | 14.0 mm | 9.5 | 19.4 mm |
| 4 | 14.8 mm | 10 | 19.8 mm |
| 5 | 15.6 mm | 11 | 20.6 mm |
| 6 | 16.45 mm | 12 | 21.4 mm |
| 7 | 17.3 mm | 13 | 22.2 mm |
| 8 | 18.2 mm | 14 | 23.0 mm |
| 9 | 19.0 mm | 15 | 23.8 mm |
Condensed view — the full half-size chart (US 3–15) is on the printable sizer.
Between two sizes? Choose the larger one.
Pick the one that fits your evening
Lay a ring that fits on the printed circles and find the one that just touches the inside edge.
Cut out the sizer, wrap it around the base of your finger, and pull until snug.
We'll send a reusable plastic sizer — the closest thing to trying the ring itself.
About string: a string can stretch or twist, so we recommend it only as a last resort — and always confirm with Method A or B.
My knuckle is larger than the base of my finger. Which do I trust?
Can I find my partner's size without them knowing?
What if the ring arrives and doesn't fit?

Carat weights are approximate for round brilliant diamonds.
"1 ctw" is a pair — not per ear
CTW means carat total weight for both earrings together. A 1 ctw pair = 0.50 ct per ear (about 5 mm each). When you compare prices anywhere, check which number is being quoted.
Where each length falls
Lengths fall differently on every body — when in doubt, size up.

Carat is weight, not size
A 1 ct round is about 6.5 mm across, while a 1 ct marquise is about 10 mm long.
Shape changes the look, not the weight. Elongated shapes — oval, marquise, pear — face up larger than a round of the same carat.
Lay the sheet on your hand
Round 1 ct ≈ 6.5 mm · Oval 1 ct ≈ 7.5 × 5.5 mm · Marquise 1 ct ≈ 10.0 × 5.0 mm.
