Option 1 : Order a ring sizer
For rings up to 5mm wide, you can easily find your ring size in the comfort of your own home. Just order a ring sizer, and we'll ship it to you. The cost of the ring sizer is deductible on your next order with us.
Option 2: Measure at home with Calipers
1. Use an existing ring that fits the desired finger. For accuracy, make sure the width of the ring used to measure matches the width of the ring you intend to purchase
2. Using calipers, Measure the internal diameter of the inside of the ring in millimeters (mm).
3. With that measurement, use the chart below to determine your ring size. If your ideal fit falls between two sizes, we recommend choosing
the larger size.
If you don't have calipers on hand, they can be purchased at local hardware stores or online
we DO NOT recommend measuring at home with any device other than calipers. Other items such as string will often give inaccurate measurements.
Option 3: Go to a local jewelry store to be sized
We recommend measuring this way for all rings wider than 6mm
1: Find a local jewelry store to be sized at.
2. Find your size with a sizer that matches the width of the ring you plan to buy (ex: if buying an 8mm band, get sized with an 8mm sizer, not a 6mm or 10mm)
3: Ask the sales associate behind the counter to measure the internal diameter of the size that fits the best. With that measurement, use the chart below to determine your ring size. If your ideal fit falls between to sizes, we recommend choosing the larger size.
