I asked my future mother-in-law, and she was pretty spot on with the size.” —murf_milo —DarthJarJar242 —Loj35 “If you do this, it’s very important to bring the string in — don’t just tell them the length. Since it is a small length with a long curve, a thicker string (or thicker ring) will be a very different size than a thin string (or ring).” —Carne_Asada_Friez “My husband somehow managed to use a ring sizer on me in my sleep without waking me up. If she’s a heavy sleeper, give this a shot.” —cregn11 BUT… “For me, this wouldn’t work. If it was out of the blue, the ring in that list would stick out like a sore thumb.” —kazabalkuskus “This is what I was advised to do at a ring shop!” —THICKSANDWICH —VirtualWhatever Author’s note: My shoe size is wayyy bigger than my ring size, so this definitely varies from person to person. “Less ornate, wider bands are easier to resize than thin, delicate, detailed bands. When in doubt, size up as it’s easier to make a ring smaller than bigger.” —FormerEnglishMajor
