How to Measure Ring Size in CM: A Comprehensive Guide

Ring Size in CM

When it comes to choosing the perfect ring, getting the size right is crucial. An ill-fitting ring can be uncomfortable and may even risk slipping off your finger. To avoid such mishaps, it's essential to know how to measure your ring size accurately. In this article, we will walk you through the steps to measure your ring size in centimeters (CM) effectively. Whether you're shopping for an engagement ring, a gift, or simply curious about your own ring size, this guide has got you covered.


Understanding Ring Sizes

Before we delve into the practical steps of measuring your ring size, it's essential to understand the basics. Ring sizes are typically denoted by a number, and in some cases, a letter. This number represents the circumference of your finger in millimeters. To convert this measurement into centimeters, we will divide it by 10.

Why Accurate Measurement Matters

Having the correct ring size ensures comfort and avoids potential hassles. An overly tight ring can lead to discomfort, while a loose one might slip off unnoticed. Knowing your ring size in CM provides a precise fit, making it easier to choose the perfect ring.


Measuring Your Ring Size

Now, let's get into the nitty-gritty of measuring your ring size in centimeters.

Method 1: Using a Ring Sizer

  1. Acquire a Ring Sizer: Many jewelry stores offer ring sizers for free. You can also find printable ring sizer templates online.

  2. Choose the Right Finger: Decide which finger you want to measure. Keep in mind that different fingers may have slightly different sizes.

  3. Slide the Ring Sizer: Slide the ring sizer onto the chosen finger, ensuring it fits comfortably. It should be snug but not too tight.

  4. Read the Measurement: Note the point where the end of the ring sizer meets the strip. This measurement in millimeters is your ring size. Divide it by 10 to get the size in centimeters.

Method 2: Using a String

  1. Gather Your Materials: You'll need a piece of string, a ruler, and a pen.

  2. Wrap the String: Wrap the string around the base of the finger you want to measure. Make sure it's snug but not too tight.

  3. Mark the String: Use the pen to mark where the string overlaps.

  4. Measure the String: Using a ruler, measure the length of the string in millimeters. Divide this number by 10 to get your ring size in centimeters.


Tips for Accuracy

To ensure accuracy in your ring size measurement, consider the following tips:

Measure Multiple Times

It's a good practice to measure your ring size multiple times at different times of the day. Fingers can swell or shrink due to various factors like temperature and humidity.

Choose the Right Finger

If you're measuring for a specific ring, make sure you measure the finger on which you intend to wear it. Fingers on the dominant hand can be slightly larger.



In conclusion, knowing how to measure your ring size in centimeters is a valuable skill when shopping for rings. It ensures that you choose the perfect fit, avoiding discomfort and the risk of losing your precious jewelry. By following the simple methods outlined in this guide, you can confidently determine your ring size and make informed decisions when purchasing rings.
