How to Measure Ring Size At Home
Unsure about your ring size? These three simple at-home methods will help you find your perfect fit.
Step-1 Make Your Own Ring Sizer

1. Wrap the string around the base of your finger.

2. Mark the point where the string overlaps with a pen.

3. Lay the string flat and measure the length in millimeters with a ruler. Use a ring size chart to convert the measurement to your ring size.
Step-2 Print A Ring Sizer
Find Your Fit

Instructions:
- Print the Printable Ring Sizer & Conversion Chart. Set page scaling to “100” in your print settings and use 8.5 x 11-inch standard paper.
- Cut out the ring sizer and the slot as instructed.
- Wrap the paper ring sizer snuggly around the base of the intended finger so that the numbers are visible and insert the pointed end through the slit you made in the sizer.
- Note the number that lines up with the slit. This is your ring size! Remember that quarter sizes are also available if your sizer indicates that you are between whole and half sizes.
Step-3 Measure An Existing Ring

Instructions:
- Print the Printable Ring Sizer & Conversion Chart. Set page scaling to “100” in your print settings and use 8.5 x 11-inch standard paper.
- Choose a ring that correctly fits the intended finger.
- Lay the ring over each size circle within the chart until you can closely match the inside edge to one of the circles on the guide. If the ring falls between two sizes, contact us to order the quarter size between them.
Ring Size Chart
All of our rings are crafted in standard US sizes.

Engagement rings, wedding bands, and fashion rings all follow the same size format.

ARE THERE ANY TYPES OF RINGS THAT CAN'T BE RESIZED?
Yes. Certain rings, such as eternity and open bands, and alternative metal styles cannot be resized due to the structure or material of their designs.
If your ring cannot be resized, we'll include that information on the product detail page of your specific style.
You may also exchange a ring that cannot be resized within our 30-day free exchange period.


HOW SHOULD A RING FIT?
A ring that fits appropriately will slide over your knuckle with minimal friction and sit snugly on your finger without feeling too tight. You should feel slight resistance but not need to apply too much force to take it on and off.
WHAT TO DO IF YOU'RE IN BETWEEN RING SIZES?
If you're in between ring sizes, we suggest sizing up rather than sizing down. Finger size can fluctuate throughout the day, and a ring that is too tight may not come over the knuckle easily — which can be painful.
Additionally, there are simple, at-home ways to make a slightly loose ring feel tighter, but you'll need to consult a professional to size it up. Remember, if a half size doesn’t feel quite right, contact us.
