How To Measure Ring Size
FIND YOUR PERFECT RING SIZE
There are two DIY methods in sizing up your finger, if followed accurately. Our rings follow US sizes, and will be the same as the sizes measured in any jewelry shops around town.
A. MEASURE CURRENT RING
Take your existing ring and measure its internal diameter (the biggest measurement). Take the readings and compare with our ring size chart for the ring size.
B. PERIMETER OF FINGER
1. Take a sewing thread and wind it snugly around your ring finger. For accuracy it should be slightly tight.
2. At the point where the thread crosses each other, take a pen to mark the two positions.Straighten the thread and measure the length in between the two points against a ruler. This measurement is the perimeter length of your finger.
3. Compare this reading to the ring size chart for your ring size.
NOTE: Do not wind the thread loosely around your ring finger. This shall cause inaccuracy in the readings.
TIPS FOR MEASURING RING SIZE
Your finger size changes depending on the time of day and the weather. For best results, measure your finger size during:
1. At the end of the day and when your fingers are warm. (Fingers are smaller in the early morning and when cold)
2. Measure finger size 3 to 4 times to eliminate an erroneous reading.

You can also print out our ring sizer from your computer at home. When printing the guide, make sure your print scale is set to 100 percent and the “fit to page” box is left unchecked in order to get an accurate measurement from the printout. Place the ring on the circles of this easy-to-use Ring Sizing Guide until you find the size that matches, or cut out the pre-measured strip of paper and use it to measure your finger.
