How to Measure
Ring Size Measurement
Method 1: Using an existing ring
Place an existing well-fitting ring on a ruler and measure the inner diameter in millimeters. Compare with our size chart above.
Method 2: Using a paper strip
1. Cut a strip of paper about 5mm wide
2. Wrap the strip around your finger at the base where you want to wear the ring
3. Mark where the paper overlaps
4. Measure the length of the paper strip and refer to our circumference chart
Method 3: Using string or thread
Wrap string around your finger, mark the overlap point, then measure the string length against a ruler.
Necklace Length Selection
Use a soft measuring tape or string around your neck to determine your preferred length. Consider the neckline of clothing you'll wear most often with the necklace.
Bracelet Size Measurement
Use a soft measuring tape to measure the circumference of your wrist at its narrowest point, just below the wrist bone. Add 0.5-1 inch (1-2cm) for a comfortable fit.
Sizing Tips
- Measure ring size when your fingers are at their largest (end of day, warm weather)
- Fingers are typically 0.5-1 size smaller in winter than summer
- If between sizes, choose the larger size for comfort
- Consider the width of the band - wider bands fit more snugly
- For stackable rings, you may prefer a slightly looser fit
- Custom and personalized items are final sale - please measure carefully
