Find your ring size with confidence
Our jewelry specialists are available to assist with sizing both before and after your order. If you’re unsure of the correct size, we recommend connecting with our team so we can guide you through the best option for your ring.
Choose the method that works best for you
Option 1: Ring sizer from our store
For the most accurate fit, we recommend using a ring sizer from our store. This allows you to measure the finger directly and confidently before placing your order.
Best for: engagement rings, custom designs, and anyone who wants the most precise sizing.
Option 2: Measure a ring you already own
Use a ring that fits the intended finger comfortably and match the inside diameter to the closest size on our ring size chart.
Best for: surprise proposals or gifting.
Option 3: Measure with a string or tape
Wrap a piece of string or flexible tape snugly around the base of the finger. Mark where it overlaps, then measure the length and compare it to our ring size chart.
Best for: at-home estimates when a ring sizer or existing ring is not available.
Helpful sizing tips
- All rings are made using US ring sizing.
- If you are between sizes, we generally recommend sizing up.
- Fingers may vary slightly between hands
- Temperature can affect finger size
- Wider bands tend to fit more snugly than thin bands
- Ring size may change slightly throughout the day
If adjustments are needed
We offer sizing support after purchase, with one-time resize support available within 30 days when appropriate. Our jewelry specialists will guide you through the best solution to ensure your ring fits comfortably and beautifully.
