PRINTABLE RING SIZER (Recommended)

We recommend using this printable ring sizer for the most accurate reading if you don't know your ring size. There are two methods you can use with the printable ring sizer: Method 1 requires an existing ring and Method 2 requires scissors.

If you have a printer, please click the button below to download the printable ring sizer. Please make sure the scale is at 100% (the instructions are on the PDF). 

PRINT RING SIZER

STANDARD US RING SIZING

We use standard US sizing. If you already know your size, please use the ring size chart below to determine your size in US sizing. 

If you have an existing ring but do not have a printer:

Please measure the inner diameter of your current ring (the inner edge of your ring) and use the table above to measure the inside diameter against US sizing.

If you don't know your ring size, don't have an existing ring and you don't have a printer:

1. Get a piece of string or cut up a thin piece of paper (make sure the piece of paper is really thin or it won't be accurate!) and wrap it around your finger firmly. (make sure the paper/string sits very firm on your finger and how you would want the ring to fit; that means it should not be loose and not extremely tight)

2. Mark the string or piece of paper to get the circumference  (in mm)

3. Lay the string or paper down against a ruler to measure the circumference (in mm/cm)

4. Then use the table above to measure your circumference (in mm) against the US ring sizing column.

5. Please choose the ring size that is closest to your circumference if you are in-between ring sizes.

Tips:

• Average ring size for women is US 6-8.
• Please measure your finger when they are warm as cold fingers will measure smaller. 
• If you are unsure but you are able to wait, we advise you to purchase a ring sizer to measure your finger before making an order.
