Ways to Measure Your Ring Size
Finding the right ring size does not have to be a guessing game. At K. Hollis Jewelers in Batavia, IL, we are always happy to measure your ring size in person for the most accurate fit. If you cannot stop in, these simple at-home methods will help you find a confident starting point.
1. Measure With a String
This quick method only requires a piece of string and a ruler.
-
Wrap a string around the base of the finger where the ring will be worn. It should feel snug but not tight.
-
Mark where the string overlaps.
-
Lay the string flat and measure the length in millimeters.
-
Compare the measurement to a ring size chart to find the closest match.
Pro tip: Measure at the end of the day when fingers are slightly larger for the most accurate fit.
2. Use a Printable Size Chart
Download and print our Ring Chart and Sizer Guide on standard US letter paper at 100 percent scale. Be sure to check the guide against a ruler before measuring.
Option 1: Measuring Tape Method
1. Cut out the paper sizer and create a loop.
2. Place it around the base of your finger and tighten until comfortable.
3. The number aligned with the slit is your ring size.
Pro tip: For wide bands over 10 millimeters, consider going up a half size.
Option 2: Match an Existing Ring
1. Place an existing ring over the printed size circles.
2. Match the inside edge of the ring to the circle.
3. If between sizes, choose the larger size for comfort.
3. Measure with a Ring Sizer Tool
A plastic adjustable ring sizer is a low-cost, reusable option and offers more accuracy than string or paper.
How to use it:
-
Form a loop and slide it onto your finger.
-
Tighten until snug but comfortable.
-
Make sure it slides over the knuckle with slight resistance.
-
Read the size where the sizer meets the buckle.

Ring Size FAQ
What's the best time of day to measure my ring size?
Measure in the afternoon or evening when fingers are naturally a bit larger. Avoid measuring when your hands are very cold or visibly swollen, since that can give you an inaccurate size.
How do I know if my ring fits properly?
A correct fit slides over your knuckle with slight resistance and sits snugly on the finger without pinching. It should feel secure but comfortable, not too tight or too loose.
Can all rings be resized?
Gold, platinum, and silver rings can usually be resized. Materials like titanium, tungsten, and ceramic are difficult or impossible to resize. Rings with stones set all the way around the band may have limits on how much they can be resized and may require special techniques.
How can I know someone's ring size for a surprise gift?
Borrow a ring they already wear on the correct finger and bring it to K. Hollis Jewelers for a discreet measurement, or compare it to a printable size chart. If you must guess, common stock sizes are about 6.5 for women and 10 for men, but keep in mind that rings with stones around the band can be hard to resize beyond one size.
Do ring sizes vary from country to country?
Yes. Different countries use different sizing systems. For example, the U.S. uses numbers while the U.K. uses letters. Use a conversion chart when shopping internationally.
What should I do if my finger size changes over time?
If your finger size shifts because of weight, temperature, or other factors, a jeweler can usually resize your ring. Many rings can be adjusted one or two sizes without stressing the metal. There are also alternatives like sizing beads. Talk with your jeweler to find the best solution for your piece.
