Q&A for How to Find Your Ring Size

Go to a reputable jeweler to get your ring resized—ideally, visit the one who originally made your ring.

Ring size can actually change depending on the time of day. In fact, your fingers tend to be pretty swollen when you first wake up, so it's better to measure your ring size at a different time.

if they wear a ring, admire it and ask if you can try it on and make note of how far down it goes and how loose/tight it is on your finger. You could also ask someone close to them who might know their sizes. Of course, a ring that is gold or silver can always be sized if you bought the wrong size. You could also take a good close up photo of their hand under some excuse or "by accident" as a good jeweler can usually look at a hand and guess pretty accurately at their size. You might also be able to sneak into their jewelry and try on a ring there and remember how it fits one of your fingers and buy one that fits you like that. If they remove a ring, trace around it onto paper when they're not looking.
