Make sure you measure your finger at the end of the day when the finger is the largest; do not measure a cold finger as this is when fingers are at their slightest. Ensure that you are measuring the exact finger (and hand) on which the ring will be worn. If you are purchasing a wide band, please increase the size by +1 size. Ring sizers are usually made for thin band.
This ring sizer works like a belt. Push the end through the buckle to form a ring shape. Put the ring sizer on your finger and adjust to give a comfortable fit. The arrow will indicate your ring size, if the arrow points to a line, that indicates it is a half size. Your ring sizer should be snug enough not to fall off, but also loose enough to slide over your knuckle, the degree of which may vary depending on which finger the ring is meant for:
- Ring and middle finger:
The knuckle is usually bigger than the base on these fingers, so the ring needs to slip quite snuggly over the knuckle. This is why it is usually a bit more difficult to take a ring on and off these fingers.
- Pinky finger:
The ring needs to sit as tight as possible but you also need to be able to bend the finger.
- Index finger:
It is the opposite for the index finger, which is usually a bit fatter at the base, so make sure to size “up” (about + 1 size) to allow your finger to bend.
