Ring, bracelet, and necklace sizing — measure at home before you order.
Getting the right size is the most important step before ordering rings or bracelets online. Use our guide to measure at home or convert between international sizing systems.
How to Measure Your Ring Size at Home
Method 1
String or Paper Strip
- Cut a thin strip of paper or string about 10 cm long.
- Wrap it snugly around the base of the finger you'll wear the ring on.
- Mark or cut where it meets itself.
- Measure the length in millimeters — this is your circumference.
- Find your size in the table below using the circumference column.
Method 2
Measure an Existing Ring
- Find a ring that fits the correct finger well.
- Place it on a ruler and measure the inner diameter in millimeters.
- Match the diameter to the table below.
💡 Tip: Fingers are slightly larger in the evening and in warm weather. Measure at the end of the day for the most accurate fit.

| 15–16 cm (6–6.3") | 17 cm / 6.7" | S – Standard fit |
| 16–17 cm (6.3–6.7") | 18 cm / 7.1" | M – Most common |
| 17–18 cm (6.7–7.1") | 19 cm / 7.5" | L – Relaxed fit |
| 18–19 cm (7.1–7.5") | 20 cm / 7.9" | XL – Loose fit |
Not sure between sizes? For rings with stones (especially eternity bands), we recommend sizing up by half a size for comfort. Wide bands also tend to fit tighter — size up if in doubt.

Sizing FAQs
Most plain band rings can be resized by a local jeweler by 1–2 sizes. However, eternity bands and rings with continuous stone settings cannot be resized. For these, please verify your size carefully before ordering.
Always measure the specific finger you intend to wear the ring on. Dominant hand fingers are often slightly larger. If your knuckle is larger than your base joint, measure the knuckle and size up slightly for comfortable removal.
Some bangle and cuff styles are adjustable. Check the individual product page for sizing details. Fixed-diameter bangles require measurement to pass over the widest part of your hand.
