How Should a Ring Fit?
A ring that fits appropriately will slide over your knuckle with minimal friction and sit snugly on your finger without feeling too tight. You should feel slight resistance but not need to apply too much force to take it on and off.
What to Do If You're in Between Ring Sizes
If you’re in between ring sizes, we suggest sizing up rather than sizing down. Finger size can fluctuate throughout the day, and a ring that is too tight may not come over the knuckle easily — which can be painful. Additionally, there are simple, at-home ways to make a slightly loose ring feel tighter, but you’ll need to consult a professional to size it up. Remember, if a half size doesn’t feel quite right, contact us and we can craft a design in a quarter size to help you find the perfect fit.
Ring Size Tips
- Our dominant hands are generally slightly larger – measure the hand you plan to wear the ring on.
- Consider the design of your ring. Rings with wider bands will fit tighter. Plan to size up by at least a half size for chunky bands (>4mm) and size down accordingly for very thin designs (<1.3mm). Note that ring sizes are generally measured in millimeters (mm) and are not sized by inch.
- Ensure your body temperature is normal – fingers tend to shrink when cold and expand when hot.
- Fingers change size throughout the day based on the water we drink and the food we eat – the best time to measure is towards the middle or end of the day.
- If your knuckle is pronounced, you may want to measure both the knuckle and the base of the finger. Then, choose a size in between those measurements as rings need to fit over the knuckle but not be too loose or tight to wear comfortably.
