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

  • Cut a thin strip from the paper

  • Wrap the strip of paper around the finger. Ensure that the paper is placed below the fingerand close enough to your knuckle.

  • 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 will 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 3: Measure Existing Rings

If you want to get the ring size without letting the other person know, you can get sneaky. You can use one of the rings worn by the individual. Wear the ring until the point where it stops. Measure the area in between the upper edge and lower edge of the ring. You can use these measurements to get a ring size. 

If there is an existing ring that fits, it can be used to measure the exact size. If you do not know the exact size in numbers, you can simply use a print chart. Place the ring over the circles and choose the size that best suits the ring at hand.

A ring is a vital investment and thus it is only proper to research extensively before determining a size. There are a few factors that should be considered when it comes to how to measure ring size at home:
  • Avoid measuring fingers in cold weather as the cold causes shrinking.

  • Fingers should be measured in warm temperatures, preferably at the end of the day.

  • If you find that the size comes under two sizes, it is best to go for the larger size.

  • Measure the size three or four times to be sure that the measurements are accurate.

  • Fingers can swell from taking steroid based medication or when pregnant. Thus, adjustments should be made accordingly.

    Yes, the technique described here is great, but the chart needs to be corrected or people will be purchasing rings too large for the actual finger size. Your chart is at least a 1/2 size off.

    Your ring sizes are wrong. I was just sized at a jeweler and then tried yours to check because yours had seemed large and they are. At least a 1/2 size larger than the jeweler sized me. I guess you are sizing larger so people's rings fit vs being tight? That's just wrong...

    Hi there, I believe your sizes are wrong. I'm a jeweler and 2 3/16" would be a size 7, not 7 1/2. I've never had an issue with a customer's ring not fitting when using my own ring sizing tools. I thought I would let you know.
