Watch this short video and follow these steps to find your ring size at home.
Gather your supplies. You'll need string, a ruler, a fine tip pen or marker, tape, and a pair of scissors.
Cut a piece of string, approximately 8 inches long.
Choose the finger you're measuring and find the thickest part. This could be your knuckle, the base of your finger, or the centre. Keep in mind that for the ring to fit on your finger it must pass over the thickest part. Your ring will typically rest on the base of your finger so if the base of your finger is the thickest then keep in mind comfort, you'll still want the ring to be tight enough that it doesn't fall off but comfortable enough that it doesn't cut off your circulation.
Wrap the string tightly around the largest part of the finger and use your pen to make a small mark where the string overlaps.
Double check your sizing by wrapping the string around your finger in different places to make sure the marks overlap or meet. If you think there's a big difference in the sizing between two or three parts of your finger then you should measure all three placements (the knuckle, centre, and base).
Tape your ruler to a surface to steady it. Line up the middle of your first mark on the 0mm line and tape your string on one end. Pull the string tight and tape on the other end. Mark the ruler in the middle of the second mark. Make sure it is in mm. This is your ring size.
Enter this number in mm on the ring order page. Choose the field indicating what part of the finger you measured (base, centre, knuckle). For greater accuracy you should repeat this process and measure each section of your finger (base, centre, knuckle).
Please be aware that engagement and wedding rings are often resized and costume jewellery goes by different sizing charts. We use Canadian/US ring sizes when converting your measurements.
