How to measure a ring in secret
Buying an engagement ring or a surprise gift for your partner? Here are our top tips on how to find their ring size in secret.
-
Ask a friend or family member.
Someone close to your partner may already know their ring size or could even try and subtly ask them on your behalf.
Measure an existing ring.
If they already wear a ring on the finger in question, why not secretly measure it? You can either take the ring to a jeweller to be measured or print our ring size guide to measure it yourself.
Measure their finger while they are asleep.

Ring measuring tips and tricks
Here are our top tips and tricks to remember when measuring ring size.
Temperature - Hot temperatures expand the skin while cold temperatures shrink the skin. So it is a good idea to consider this before measuring.
Weight loss or gain - Any weight changes will impact how loose or tight the ring will fit.
Pregnancy - Just like weight, pregnancy can impact ring size. Bear in mind that fingers will be more swollen.
Comfort - Consider how easy it is to put on your finger and allow your finger to swell or shrink depending on the temperature.
Time - The best time of day to measure ring size is in the evening as the fingers are bigger in the evening when compared to the morning.
Ring resizing options
Don’t worry if you don’t get it right the first time, as we offer a 30-day free resizing for up to two sizes up or down.
