7 Ways to Size a Ring

By on Monday, April 04, 2011 12 Comments

There are a number of ways to size a ring. Each method has its pros and cons. Accuracy varies too and this must be taken into account especially if you are making rings for someone else far away.

Methods which use existing rings are better because the rings are already known to be a good fit for the fingers. A ring must not only fit comfortably but be just big enough to ease over the second knuckle.

Just to confuse things, be aware that ring sizing nomenclature differs internationally. Remember fingers also tend to be smaller in the morning and swell a bit more later in the day. So it is best to take measurements at the end of the day.

1. String
Take a piece of string and wrap it around the finger. Mark where it overlaps and measure the distance between the markings. This distance is the circumference. This online conversion site saves you from having to do the math to determine the diameter in inches or mm. It also gives 5 other international ring sizing conversions by simply typing in one value.


This is probably the most inaccurate method because the string you use may stretch. As you can see in the picture, the broader marker marks also add to the uncertainty.

2. Ruler or Calipers
Just measure the internal diameter of the ring and read off a ring size chart to get the ring size. Good calipers are much more accurate than rulers. Also check my past post on how to use vernier calipers if you have one.


3. Ring Mandrel
Using the ring mandrel is okay but not that accurate especially if the ring band is broad. Where do you read the size?  In this example, the ring is approximately over the size 6 mark. However, the edges of the ring indicate sizes larger and smaller than 6.  The best way is to determine the size at approximately the middle of the ring.



4. Ring Gauges
Shown here is a professional qualily ring sizer.These ring gauges cover a range of sizes and are available in metal as well as cheap plastic ones.  It is handy to have if the person doesn't have a ring on at the time you need to know what ring size they wear. This method will naturally not work if your potential client is far away!

5. Cut Out Ring Sizer
There are many different paper ring sizers available for print out on the internet. The idea is to place the paper band around the finger and read off the number.  The better ones require making a slit in the paper cut out and then wearing it like cinching in a belt.  Here is one example from the Jewelry Mall. They also include a toe ring sizer!


6. Ring Diameter Template
Blue Nile Canada has a great printable template with various diameters of rings to compare with. It's important to follow their instructions to confirm the size of the paper otherwise accuracy goes out the window.


The template comes with actual diameter of rings in mm which can then be cross-referenced with their international ring sizing charts

7. Online Ring Sizer
A really cool online tool is Find My Ring Size. The software includes a way of calibrating your screen so that the round circles are the right size.  It's very convenient but care must be taken to pick the right circle and hence the right size. The ring should just enclose the circle on the inside.

  8. Hey I stumbled across your blog and found this post to be quite informative. I was always having trouble trying to find what my ring size was. Now I have lots of ways on how to get my right ring size. On all of your suggestions, I prefer the string and the ring template to be most effective. Your blog rocks...thanks for the great ideas

  10. Wow, so many ways to skin a cat...oops, bad simile, now I'll have the Animal Rights Association up in arms. :D
    Seriously though I've hesitated to make rings as there are so many sizes of fingers, guess that's why some places offer only a size 6 or 7 and then the customer has the ring sized to fit. Hmm, too bad they can't do that with shoes!

  11. The printable ring sizers are great when they provide a reference measurement to check the image. Some online printable sizers provide a measurement of 3 1/2 inches that you can then cross check against a ruler to make sure the printout is scaled right. I made the mistake of printing a sizer out without a scale and the result was I got a measurement that was way off. As a result, I have found one image that requires I scale the printer to 95% to get the correct image size.

    1. That's a very good observation about needing some sort of scale. Thanks for sharing.
