Find Your Ring Size

While the most precise way to find your ring size is to have a jeweler do it, it’s still possible to do this at home. Either way, you want to make sure you know your exact ring size before you decide to order a ring. You can do this by measuring your finger and converting the measurement using a ring size chart or ruler. Alternatively, you can use a ring you already own and compare it to a sizing chart.

Measuring Your Finger

  1. Wrap flexible measuring tape around your finger. Wrap the tape close to the knuckle; this is the thickest part of your finger and you want to ensure the ring slides on comfortably. Make sure you use a cloth or plastic measuring tape; these will wrap around your finger more effectively. Using a metal tape measure is possible, but will be significantly more difficult and could even cause an injury.
    • Alternatively, many jewellers offer printable ring sizers on their websites. You can use these much like a tape measure, only the ring sizes are visible on the ruler itself, saving the work of converting measurements.
    • Don’t wrap the paper too tightly. Aim for a snug but comfortable fit.
    • Make sure to use the exact finger you want to size for. For an engagement ring, you should be sizing your left ring finger. This is because the size of your two ring fingers might be slightly different.[1]
    • The size of your fingers tends to change throughout the day. For best results, measure at the end of the day.[2]
  2. Record the measurement where the tape overlaps. Do this on a separate piece of paper with a pen or pencil. You can record the measurement in inches or millimeters, depending on the retailer. Many will have both measurements available but a European retailer might only have measurements in millimeters.
    • If using a printed ring sizer, mark the point where it overlaps directly on the ruler itself.
  3. Compare the measurement to a sizing chart. You can find these charts at many online jewelry retailers. You can print this chart for easy reference, but usually you’ll just need to compare to the online chart. These charts convert measurements into ring sizes; for instance, 2.34” (59.5mm) would be a size 9.
    • If your measurement falls between two sizes, go for the largest size.
    • If using a printed ring sizer, note where you marked the overlap to determine your ring size.

Using a Circular Sizing Chart

  1. Find and print a ring sizing chart. Many online jewelry retailers offer printable charts that show a number of circles of different sizes.[3] If you print the chart from the jeweller you plan to order from, you’ll know the sizing on the chart will match the sizing of their products.
    • In order to ensure that the size chart is not distorted in printing, make sure any scaling options on your printer are turned off.
  2. Find a ring you own that fits the finger you’re trying to size. Choose a ring that fits snugly, but isn’t too tight. Make sure the ring fits the correct finger; even your two ring fingers can be different sizes.
  3. Place your ring over the circles on the chart. The circle should match the inside of the ring for the perfect fit.[3] If you are having trouble choosing between two close sizes, you should opt for the larger size.

Tips

  • Certain metal rings cannot be resized, while others have resizing limitations. Consult your jeweler if you have any questions or concerns.
  • Your fingers might also swell if you're pregnant or taking certain medications. Take this into account when measuring your ring size.
  • Most jewelry stores will only charge once for resizing, even if the ring needs to be resized multiple times. A reputable store should not charge you separately for every attempt.
  • If shopping for a wedding band, find out whether your ring is a "comfort fit" band. Comfort fit, while much more comfortable, can sometimes affect your ring size. Let your jeweler know if you are planning to purchase a comfort fit ring.
