Ring Sizing Guide
Ring sizing is a tricky thing to get right so we would always recommend going to a high street jeweller to get your finger sized properly. There are lots of online methods for measuring your finger, but they are never accurate and as resizing can be tricky and costly, particularly if there are stones in the ring, it is best to get it right first time around. Most high street jewellers will also offer this service for free. The following should also be considered when getting your finger sized.
- Your size may vary by up to a size from summer to winter.
- For wide rings with a flat interior or for spinner rings, you may need to go up one or two sizes.
The thicker the ring, the tighter the fit, so if you choose a ring with a deep band width, you will likely need to go one size up. The best time of day to measure is in the evening, when your fingers are largest. Avoid measuring when you’re cold, as fingers are at least half a size smaller.
