Getting an accurate ring size is essential for both comfort and security. The ring size guide will help you determine your correct size at home.
Method
Take a ribbon, string, or a thin strip of paper and wrap it around the base of your finger, close to the knuckle. Mark the point where the end overlaps with the rest. Then, lay it flat and measure the length in millimeters to find your finger's circumference.
Some Tips:
Make sure you're at a comfortable, normal temperature-- Your finger size can fluctuate. Cold weather can cause your fingers to shrink by up to half a size, while heat, humidity, or medical conditions may cause swelling and have the opposite effect.
Measure the Correct Finger-- It might seem obvious, but be sure to measure the specific finger you plan to wear the ring on. And fingers on your dominant hand are often slightly larger than those on your non-dominant hand.
Consider the Ring's Band Width-- Wider bands fit more snugly than narrow ones. If you are choosing a ring with a broad band, you may need to go up half a size or even a full size for a comfortable fit.
