Buying a ring online without knowing your exact size is one of the most common reasons for returns and exchanges. The good news: you can measure your ring size accurately at home in under five minutes, no jeweller required.
What is the easiest way to measure ring size at home?
Wrap a thin strip of paper or string snugly around the base of your finger, mark where it overlaps, then measure that length in millimetres. Divide the measurement by 3.14 (pi) to get the diameter, then match it against a standard ring size chart. Most people fall between size 5 and 9 (UK size J to R).
What time of day should I measure my finger?
Measure in the evening, since fingers are naturally slightly larger later in the day due to normal fluid retention. Avoid measuring right after exercise, in very cold weather, or right after waking up, as these can all temporarily shrink or swell your finger size.
Does finger size differ between hands?
Yes. Your dominant hand is often slightly larger. Always measure the specific finger on the specific hand you plan to wear the ring on.
What if I'm between two sizes?
Size up rather than down. A slightly loose ring can be resized smaller or worn with a simple ring guard; a ring that's too tight is uncomfortable and harder to adjust.
Can stainless steel and sterling silver rings be resized?
Sterling silver rings can typically be resized by a jeweller. Stainless steel rings, prized for being tarnish-resistant and hypoallergenic, are more difficult to resize due to the hardness of the metal, so getting the measurement right from the start matters even more.
