How to Measure Ring Size at Home

Not sure of your ring size? Use these easy at-home methods to find the perfect fit with confidence.

Method 1: Use a Ring Sizer

A physical ring sizer is the most accurate way to find your ring size at home. Simply wrap it around your finger and adjust for a comfortable fit—secure enough to stay on, yet loose enough to slide over your knuckle.

Complete the form below to request your free reusable ring sizer. Please note that filling out the fields will automatically submit the form.

Method 2: Use Our Printable Ring Sizer

Need to find your ring size quickly? Download the JSN Jewels Printable Ring Sizer for a fast and convenient at-home measurement. While this method provides a reliable estimate, we recommend confirming your size with our complimentary ring sizer for the most accurate fit.

  1. Download and print the JSN Jewels Ring Sizer at 100% scale on standard 8.5 x 11-inch paper.
  2. Carefully cut out the ring sizer and the slot following the printed guidelines.
  3. Wrap the sizer around the base of your finger and insert the pointed end through the slot.

Method 4: Measure with a Tape Measure

A flexible tape measure provides a quick and accurate way to determine your ring size by measuring your finger's circumference.

What You'll Need

  • A flexible measuring tape

How to Measure

  1. Cut a thin strip of paper approximately 5–10 mm wide.
  2. Wrap the paper strip around the base of the finger where you plan to wear your ring.
  3. Ensure the strip fits snugly but comfortably—not too tight or too loose.
  4. Mark the point where the end of the paper overlaps.
  5. Lay the paper strip flat and measure the distance from the starting end to the marked point using a ruler (in millimeters).
  6. Compare your measurement with the below JSN Jewels Ring Size Chart to find your perfect ring size.

Don't Have a Tape Measure?

You can also use a piece of string, yarn, dental floss, or a thin strip of paper. Wrap it around your finger, mark where the ends meet, then measure the length with a ruler. Compare this measurement with our ring size chart to find your perfect fit.
