Avoid the Hassle: How to Determine Your Ring Size Without Leaving Home

Posted by Jewel Heart on

Buying a ring shouldn't be complicated. Traditionally, you would visit a jewelry store, try on rings, and find the perfect fit. However, with the rise of online shopping, determining your ring size has become a bit more challenging. You can't physically try on the ring, but there are still reliable methods to measure your ring size accurately from the comfort of your home. This guide will help you navigate the process of figuring out your ring size online using simple tools and techniques.

  1. Measure Your Finger

Use Floss or String

One of the simplest ways to measure your ring size is by using a piece of floss, string, or even a strip of paper. Here’s how to do it:

  1. Wrap the string around the base of your ring finger.
  2. Mark the point where the string overlaps with a pen.
  3. Straighten the string and measure the length in millimeters using a ruler. This measurement is the circumference of your finger.

Pro Tip: Measure your finger multiple times to ensure accuracy.

Use a Ring Sizer Tool

If you prefer a more precise method, download and print a ring sizer tool. Many jewelry websites offer downloadable ring sizers that you can use at home. Make sure to print it at the correct size, cut it out, and follow these steps:

  1. Wrap the tool around the widest part of your finger, usually the knuckle.
  2. Keep wrapping until the fit is snug.
  3. Look at where the arrow points. The closest number to the arrow is your ring size.
  1. Use a Ring Size Chart

Once you have the circumference of your finger, you can use a ring size chart to find your size. Here’s a handy guide:

  • A ring size of 1 corresponds to a circumference of 39.1 mm.
  • If your measurement falls between two sizes, opt for the larger size.

For instance, if your finger’s circumference is 58 mm, your ring size is likely 8.5.

  1. Use a Ring You Already Own

If you have a ring that fits perfectly, you can use it to find your ring size. Place the ring on a true-to-size ring sizing chart, which features circles representing different ring sizes. Match the inside edge of your ring with the closest circle.

Factors to Consider When Determining Ring Size

Large Knuckles:

If your knuckle is significantly larger than the base of your finger, measure both and choose a size in between for a comfortable fit.

Band Width:

Wider bands tend to feel tighter. If you are sized for a narrow band, you might need to go half a size up for a wider band.

Temperature and Time of Day:

Measure your finger at room temperature and later in the day when your fingers are at their largest.

Common Methods for Determining Ring Size

Printable Ring Size Chart:

Print a chart with circles of different sizes. Place your existing ring on the circles to find the best match.

Paper Ring Sizer:

Wrap a strip of paper around your finger, mark where it overlaps, measure it, and compare the length to a ring size chart.

String Method:

Similar to the paper sizer, but using a piece of string.

Note: While these methods are helpful, they can sometimes be inaccurate. For the most reliable measurement, use a proper ring sizer tool.

The Best Method to Determine Ring Size

Use a Ring Sizer:

The most accurate way to determine your ring size is to use a plastic or metal ring sizer. These tools are universally used by jewelers. Visit a local jewelry store and have your finger measured by a professional. If visiting a store is not an option, consider purchasing a plastic ring sizer online.

Online Shopping and Ring Sizing

With the convenience of online shopping, it's essential to ensure you get the correct ring size. Follow the methods outlined above to measure your ring size accurately. This way, you can confidently order your ring online without worrying about it not fitting.

Remember, a well-fitting ring should slide over your knuckle with slight resistance and sit comfortably at the base of your finger without feeling too tight or too loose.


Measuring your ring size online is straightforward with the right tools and techniques. Whether you use a string, a downloadable ring sizer, or a professional ring sizer tool, you can find your perfect fit without leaving home. With these methods, you can ensure that your new ring will fit perfectly, making your online shopping experience seamless and enjoyable.

How can I know my ring size online?

  • Printable Ring Sizer:

Some apps allow you to measure your ring size by placing your finger on your phone screen or by using a reference ring.
