1. If you are between sizes, order a larger size. It's much easier to size down on a ring than to size up if you need to have it re-sized.
2. When measuring, make sure your finger is at a normal body temperature. Fingers tend to expand when hot, and shrink when cold, and the difference could be up to a full size or more! So don't measure after you've been to the gym, or if you're outside on a cold day, for example.
3. When measuring, make sure you can slide the ring on and off your finger, over the knuckle. You're looking for a snug, not tight fit.
4. Don't want to order a ring sizer? You can also measure across the diameter (across the inside middle of the ring) on another ring that fits your finger that you're looking to buy the ring for. Use the chart below to find out your size!
Option 1: Measure a ring
If you already own a ring that fits on the finger you’re measuring, this is perfect. If you measure the internal diameter of your ring (in mm), that is, across the middle of the ring, inside to inside. It should match with the corresponding size in the ring chart below.
Option 2. Measure your finger
Measure a ring with a string or a thin strip paper. This can be easily done and can help find your size. Cut a long string or piece of paper that's about 6-inches long, wrap it snugly around the base of your finger, but make sure to not let the string stretch while you're wrapping it around your finger. Be sure the paper or string can slide on and off over your knuckles. Then, mark the spot where the string or paper meets and measure that.
Option 3: Ask around
There is a chance that her close friends or family already know her ring size, especially if you two have already discussed marriage in your future together. Don’t be afraid to reach out to someone you can trust to keep the secretary - they might have the information that you need!
Option 4: Take a guess or send us a photo
When designing rings for collections, the industry uses a size 6 as the ‘average’ finger size. Knowing this, you may be able to guess if she may size up or down based on whether she has smaller hands or fingers. Also think about what is her dominant hand - usually the non-dominant hand is half a size smaller. For example, if she’s right handed and wears a ring on her right hand ring finger, you could probably safely get something half size smaller.
