Three Methods:Graduated Sizing CylinderPrintable Ring SizerMeasure Your Finger

If your ring is the correct size for your finger, it's less likely to fall off. Having the right size ring also makes it easier to keep the gemstone or any ornaments on your ring facing out as they should, and gives you a way of ordering correctly sized rings, or resized rings, sight unseen.

Method 1
Graduated Sizing Cylinder

  1. Image titled Size Rings Step 1
    Slide the ring onto the narrow end of the sizing cylinder. Keep sliding the ring up the cylinder until it won't go any further.
  2. Image titled Size Rings Step 2
    Read the ring size where the ring meets the graduated cylinder.

Method 2
Printable Ring Sizer

    • Make sure your print is set to print at 100% zoom, or "no scaling," to ensure that the chart prints at the correct size.
  2. Image titled Size Rings Step 4
    Lay the ring you want to size on top of the ring sizing guide. Shift the ring around until you find a circle the matches the inside of the ring exactly.
  3. Image titled Size Rings Step 5
    Read the ring size off the circle.

Method 3
Measure Your Finger

  1. Image titled Size Rings Step 6
    Wrap a flexible measuring tape around your finger where you want the ring to sit. Then slide the tape over your knuckle so you can be sure the ring will be large enough to fit over your knuckle, too.
    • Read the measurement off the measuring tape, then use a sizing chart, such as the ones at (inches) or (mm), to convert the measurement to a ring size.

    Alternatively, you can print off the ring sizing band located at either of the sizing chart links. Cut a slit where marked, wrap the paper band around your finger and poke the end of the band through the slit, pull it firm, and read your ring size where the paper passes through the slit.


  • Your ring size changes over time, especially if you gain or lose weight.
  • Measuring your own finger to determine ring size can be a challenge, because you effectively have the use of only one hand. A friend's help will make the process much easier.
  • Remember, your ring must be large enough to not only sit comfortably on your finger but also fit over your knuckles.
  • The United States and Canada, the United Kingdom, Europe, Asia and Australia all have their own sizing scales for rings. If you're having a ring resized or ordering a ring in a certain size, make sure that you and the person you're dealing with are speaking in the same units of measure.
  • Each of your fingers may be a different size, so always size each finger individually--even the same fingers on opposite hands.
