Method 1: The String Method
All you need for this is a string and your desired finger. For this method we recommend a sewing thread for it is very thin, giving more accurate results.
Simply wrap the thread around your finger without pulling on the thread to tightly. You should see no signs of applied pressure on your finger. Make sure the thread isn’t loose either. You want to try your best to have the thread follow the exact circumference of your finger.
Once you have the thread wrapped around in its ideal position, take either a marker or some scissors and draw or cut the area where the 2 ends meet. Either with our size guide (Thanks to Overstock Silver) or with a ruler at home, take your string and measure how long it is. The ring sizes of your corresponding length is listed in the picture attached.
