Ring Sizing Chart

International ring size 

Our ring sizes are all in US sizes. If you are ordering from outside of the US, Canada, or Singapore, determine your ring size according to your country’s standard. Next, refer to the International Ring Size Chart below to find out your corresponding US ring size. You will be able to take a ring size that is 0.25 up from the stated sizes. For example, if you are a US Size 6, you will also be able to fit a US 6.25 comfortably.

Measuring your finger

1. Use the attached guide. Select a ring that properly fits the intended finger. 

2. Place the ring over the circles, matching the inside edge of the ring to the circle nearest in size. This measurement refers to the inside diameter of the ring.

3. If the ring falls between two sizes, order the larger size.

Your ring should fit your finger comfortably; snug enough so that it will not fall off, but loose enough to slide over your knuckle. Finger size changes depending on the weather and the time of day. For optimal results, measure your finger size:

  • At the end of the day and when your fingers are warm (Fingers tend to be smaller in the early morning or when you are cold.)
  • Measure your finger at least 3 to 4 times to rule out any erroneous reading.

Avoid using string or paper to measure your ring size as these materials can stretch or twist, yielding an inaccurate measurement.

Buying a ring as a gift

Ask your significant other's friends or mother if they know her finger size. Borrow one of your significant other’s rings (from the correct finger) and use the ring measurements above to determine its size.
