How to measure a ring in secret
Ask a friend or family member
A close friend or family member may already know your partner’s ring size or can casually ask without raising suspicion.
Measure a ring they already wear
If your partner wears a ring on the right finger, quietly borrow it and have it measured by a jeweller, or use our printable ring size guide at home.
Measure their finger while they sleep
Wrap a piece of string around your partner’s ring finger while they’re asleep and mark or tie it. Then compare to our ring size guide to find the correct size.
Ring measuring tips and tricks
Temperature
Warm weather can cause fingers to swell, while cold temperatures may make them shrink.
Weight changes
Weight loss or gain can affect how snug or loose a ring feels on your finger.
Pregnancy
Pregnancy can also change ring size, as fingers often become more swollen during this time.
Comfort
A well-fitting ring should slide on easily while allowing for natural changes in finger size throug the day.
Timing
Measure your ring size in the evening, when fingers are naturally at their largest.
