DAJ International Ring Size Conversion Chart (optimized)

Ring size is a measurement used to denote the circumference of jewelry rings.

There are several systems for denoting the sizes of jewelry rings in use around the world:

Method 1: Use Paper Strips

What you need

To be able to measure the ring size using a paper strip, you will need the following equipment:

  • Thin strip of paper
  • Ruler

How to measure

  • STEP : 1 Cut a thin strip from the paper
  • STEP : 2 Wrap the strip of paper around the finger. Ensure that the paper is placed below the fingerand close enough to your knuckle.
  • STEP : 3 Mark the area where the paper strip meets, then use the ruler to measure the distance.

Notes to bear in mind

It is important to note that people with large knuckles will need to slide the ring through the knuckle. So, this should be taken into account when sizing the ring. Also, the size of the finger changes with changes in temperature, physical exercise, weight changes as well as medication.

If you are in doubt about the size, it is always ideal to go a size higher than lower.

Method 2: Use Paper Strips

What you need

  • String
  • Ruler
  • Pen

How to measure

  • STEP : 1 Cut a string that is 6 inches long.
  • STEP : 2 Wrap the string around the base of the ring finger, slightly below the knuckle.
  • STEP : 3 Use the pen to mark the string where it ends.
  • STEP : 4 Lay the string on the ruler with the area marked on your right.
  • STEP : 5 The number closest to the pen mark is the ring size in inches.
  • STEP : 6 You can use the ring chart BELOW to translate the measurements into a ring size.

Also: If there is no string or paper available, masking tape can be used, a wire or a twist-tie can also be used.

The average adult woman’s ring size is ranged in between USA size 5 to 8, whereas the average adult man’s ring size is ranged in between 8 to 11.

For countries sizes not on the chart, you may just google for it on the internet.

Ring sizes can be measured physically by metal ring sizer in most local jewelry stores.
