Ring Size Guide
Measuring your ring size at home is easier than you might think. You can use a ring size chart or something as simple as a piece of string to find your size. Many jewelers will measure your ring size for free, but it’s just as convenient to do it yourself. Whether you’re planning to buy from your favorite jewelry shop or dropping hints about that stunning engagement ring you’ve been eyeing, follow these easy steps to ensure the perfect fit.
How to Measure Your Ring Size with String
Found the perfect ring? Follow these instructions to find your perfect size.
- Grab a soft measuring tape, string, or a thin strip of paper.
- Wrap it around the finger where you plan to wear the ring—keep in mind the position on your finger, especially if you’re stacking rings. Mark the point where the ends meet.
- Place the string or paper on a flat surface and use a ruler to measure the length from the start to the mark. Compare this measurement with the size chart above to find the closest ring size.
