How to find her ring size secretly
The short answer. Borrow a ring she already wears on her ring finger and trace it, press it into soft material or have a jeweler measure it. Ask her sister or a close friend, or look at a ring she keeps in a box. If you can not find out, buy a size close to average and offer a free resize.
Borrow a ring
The most reliable method is to borrow a ring she wears on her ring finger, or the same finger on the other hand, which is usually close. Take it to a jeweler to measure, or press it into a bar of soap or a piece of paper to draw the inside circle. Measure the diameter in millimeters and convert it.
Ask someone else
Her sister, mother or closest friend may already know. Friends may also have been with her when she tried on rings, and they sometimes remember the size.
Use a photo of her hand
If you can not get a ring, a clear photo of her hand next to a coin or ruler can give an estimate. HerDreamRing detects her finger in a photo on her device and uses it to show the ring in 3D at her size. That is for fit and look, not a replacement for a jeweler’s measurement.
If you can not find out
Most jewelers resize for free or low cost within a limited period. Buy within one size of the average and be ready to resize. Rings with eternity bands or complex shanks can not always be resized, so check before choosing one.
Common questions
What is the most common engagement ring size?
In the US, sizes 5 to 7 are the most common; in the UK, J to N. Sizes vary a lot, so it is only a fallback.
Can an engagement ring be resized?
Most plain bands can be resized one or two sizes up or down. Rings with pavé all round, patterned bands or tension settings are harder or impossible to resize.
