Understanding US Ring Sizing

Women’s sizes usually range from 3-13 while men’s range between 8-16 with both using some numerical system to denote their sizes. Each number indicates a specific diameter and circumference of the ring. Here are some basics about US ring sizes:

  • Diameter: This refers to the inner diameter of the band measured in millimeters.
  • Circumference: It corresponds to the internal perimeter of the band measured in millimeters that can be calculated by multiplying diameter by pi (3.14).


Using a ruler to measure the diameter of a ring is important because it provides an accurate and straightforward way to determine the ring's size.
This method is simple, accessible, and effective for ensuring a proper fit.

Using a Ring You Already Own

  1. Get a Ring That Fits: Choose a ring that fits the finger you want to measure.

  3. Refer to Chart: Take reference from the US Ring Size Chart above, to find out your size corresponding to this diameter.

Second method

Almost everyone has access to paper or string at home, making this method convenient and cost-effective.
By using paper or string, you can quickly and easily determine your ring size without needing to visit a jeweler or purchase a ring sizer.

Method 2: 
Using a String or Paper Strip

To determine the right size for your new ring, follow these steps:

  1. Cut a Piece of String or Paper: Make sure it is long enough for wrapping around your finger.
  2. Wrap Around Your Finger: Please, wrap the string or paper all round the lower area of your finger. Confirm that it holds tightly, but not too tight.
  3. Mark the Overlap: Mark with something where two ends meet.
  4. Measure Length: Make sure that string or paper is flat and then take measure from its beginning up to mark recorded in millimeters.

Tips for Accurate Ring Size Measurement

  1. Do This at The End of The Day: In mornings your fingers may be smaller than usual and most likely you will feel them slightly swollen after a day’s work. It is better done when they are in bigger size compared earlier on during rising sun hours yet again.
  2. Consider Knuckle Size: For example if you have big knuckles, it would make sense taking measurements both at base as well as knuckle level then pick something between them like 7.5 for instance.
  3. Temperature Matters: A lot of Cold weather will cause your fingers to shrink while warm weather has the potentiality of swelling them Therefore room temperature measurement gives accurate results.
  4. Take Multiple Measurements: To ensure accuracy, measure your finger more than once

Ring Sizing for Different Ring Types

Different types of rings may require slightly different sizing considerations:

  • Wide Bands: Wider bands fit more tightly and may require going up half a size for comfort
  • Stackable Rings: When buying stackable rings think about how they will fit together; you might need one size larger so that many rings can fit on one finger.
  • Engagement Rings and Wedding Bands: These are often worn together & therefore both should fit without being too tight.
