How to Ensure the Best Fit for Your Ring
When purchasing a ring, it’s essential to select a size that offers both comfort and security. A well-fitting ring should be snug enough to stay in place without risk of falling off, yet loose enough to take on and off comfortably.
Finding Your Ideal Fit
-
Striking the Balance: Every finger has a range of sizes between too tight and too loose. Personal preference plays a role—some people prefer a snug fit, while others enjoy a slightly looser feel. Ultimately, only you can decide what feels best for you.
-
Measure Multiple Times: Finger size can fluctuate with temperature, time of day, and physical activity. To ensure accuracy, measure your finger size more than once, at different times of the day.

Consider Ring Width
Wider rings feel tighter than narrower ones, so we recommend choosing half a size larger for a comfortable fit. This also applies when stacking rings or adding to wedding jewellery on the same finger, as multiple bands can make the fit feel tighter.
Buying a Ring as a Surprise
If you’re planning a surprise, there are ways to get the sizing right without directly measuring their finger:
-
Borrow a Ring: If they already wear a ring on the correct finger, discreetly borrow it and have it measured by a jeweller.
-
Hand Dominance Matters: Keep in mind that finger sizes vary depending on hand dominance. For example, the ring finger on their dominant hand is likely to be larger than the same finger on their non-dominant hand.
