How to Measure Your Finger Size Without Visiting a Jewelry Store

So you want to buy a ring…

Whether purchasing an engagement ring, wedding band, or anniversary ring, the most important step is to measure your ring size. If you don’t know your finger size, finding a ring that fits perfectly on your hand will be challenging, especially if you’re shopping for rings online.

Here’s the good news: you no longer have to visit a jewelry store in person to measure your ring size.

You can confidently and accurately measure your ring size from the comfort of your home.

4 Ways to Measure Ring Size at Home

Any of the following methods will help you accurately determine your ring size.

You can even try multiple methods to double-check your measurements to ensure the most comfortable fit.

  1. Use a ring that fits.

    If you already have a ring, use it as a guide when measuring your finger size. Does the ring still fit perfectly? Then, confidently order your new ring in the same size! However, if the ring is a little loose or a little tight, you might want to consider moving half a size in either direction.

If you are unsure about the finger size of your existing ring, measure the inside diameter of your ring. Then, match the measurement with the finger size in our ring size chart to find your ring size.

  1. Request a free ring sizer.

  1.  Use a String and Ruler.

    To measure your ring size using a string and ruler, wrap a piece of string around the base of your ring finger. Use a marker or pen to mark where the string fully wraps around your finger. Next, pull the string tightly against the edge of a ruler. Wherever the mark on the string hits the ruler, that is your finger size! Be sure to measure in millimeters (mm). You can then use our ring size chart to determine your ring size. 

  2. Convert from other units.

    Do you know your ring size in other units? Different countries use different measurement units, resulting in different ring sizes. European sizes, for example, tend to use larger numbers than the US and Canada sizes. If you were to order a ring in the US using a European size, then your ring would be far too big. To avoid this issue, use our ring size chart to convert appropriately. We make it as easy as possible!
