How to Measure Ring Size

Choosing the right ring size is crucial when shopping for a new piece of jewelry. Whether you are buying a ring for yourself or as a gift for someone else, knowing the correct ring size ensures a comfortable and perfect fit. In this guide, we will show you how to measure ring size accurately so you can make the right choice.

Use a Ring Sizer Tool

One of the most accurate ways to measure ring size is by using a ring sizer tool. This tool consists of a set of rings in various sizes that you can try on to determine which one fits your finger best. Simply slide the rings onto your finger until you find the one that feels comfortable and snug.

Measure Your Finger

If you don’t have access to a ring sizer tool, you can measure your finger using a piece of string or a strip of paper. Wrap the string or paper around the base of your finger and make a mark where the end meets. Then, measure the length of the string or paper in millimeters to determine your ring size based on a sizing chart.

Consider the Ring Width

Keep in mind that the width of the ring band can affect the fit of the ring. Thicker bands may require a slightly larger size to ensure a comfortable fit, while thinner bands may fit more snugly. If you are unsure, it’s best to consult with a jeweler to get the right size for the specific ring you are interested in.

Measure Your Existing Rings

If you already own a ring that fits well, you can use it to determine your ring size. Simply measure the inside diameter of the ring in millimeters and compare it to a sizing chart to find your size. Be sure to measure the ring at the widest point to get an accurate measurement.

Consider the Temperature

It’s important to consider the temperature when measuring your ring size, as your fingers may swell or shrink depending on the weather. For the most accurate measurement, it’s recommended to measure your ring size when your fingers are at a normal temperature.

Consult with a Professional

If you are still unsure about your ring size, it’s best to consult with a professional jeweler. They have the expertise and tools to accurately measure your finger and recommend the right ring size for you. A professional jeweler can also provide guidance on choosing the best ring style and fit for your preferences.


Measuring ring size accurately is essential to ensure a comfortable and perfect fit for your jewelry. Whether you use a ring sizer tool, measure your finger with string, or consult with a professional jeweler, taking the time to determine the right size will result in a piece of jewelry that you can enjoy for years to come.
