5 Ways to Measure Ring Size

How to measure ring size at home

Do you have trouble finding rings that fit? You're not alone. It can be tricky to get the perfect ring size, especially when you like to purchase rings online. But don't worry - we're here to help. In this article, we'll show you how to measure your ring size at home so you can shop for fidgeting rings with confidence.

We know that it's not easy to predict someone's ring size based on clothing size or anything else. That's why we offer free returns and exchanges on all of our rings so that you can find the perfect fit. Let's get started!


The most accurate way to find your ring size is to go to a jeweler. But that doesn't really fit with the whole doing-it-all-from-my-home thing we've all got going on. That's why we put together some pointers to keep in mind when measuring your finger size at home.

1. When to Measure

Our finger size changes throughout each day. It can be influenced by heat or cold weather, medication, diet, water retention, hormones, and other factors. Therefore, our recommendation is to measure your ring finger multiple times over the course of a day.

Also, the fingers on our dominant hand tend to be half size larger than those of non-dominant hand. So it is important that you take the measurement for the finger on which you want to wear the ring. 

2. How to Know if a Ring Fits Properly

A ring that fits well should feel comfortable and snug on your finger. When you try it on, you should be able to slide it over the knuckle but not push it down your finger. If the ring is too loose, it can easily fall off; it can cause pain and discomfort if it's too tight.

Consider Your Knuckle

When you measure your intended finger, it's essential to keep in mind the size of your knuckles. If you have arthritis or another condition that affects the size of your knuckles, it can impact the fit of a ring. Given this, you should measure the part of your finger where the ring will sit and your knuckle. You should choose a size that will fit over the knuckle.

Measuring for Wide Band Rings

If you're looking for a wide band ring over 7 millimeters or 0.27 inches, you should go up a full size in the Australian and British alphabetical ring sizing system. For US, numerical ring sizes going up half a size would do.

What to Do if Your Exact Size Isn't Available

The most common ring sizes for women are US 7 to 10, and most jewellery stores will carry a selection covering these sizes. If your exact size is not available, you have a few options. You can either choose a size closest to your measurement or go up or down half size depending on the finger you will be wearing the ring on.


Below are four easy ways to measure ring size in the comfort of your home using a string, a ring size chart, and a ring sizer.

Method #1: The Finger Circumference (String Test)

Only use this approach if you're willing to take a risk because it is less accurate. It's great if you have someone to help you with this.

What you need: pen; ruler; string/floss or a strip of paper and a little free time.

  1. Cut a piece of string/floss or flexible paper strip at least 15 cm (6 inches) long and 0.5 cm (0.25 inches) wide.
  2. Wrap the string or strip of paper around the base of your intended finger. Make sure it is snug but not too tight. Try not to pull them to taut.
  3. Mark the point on the string or paper where it meets, ensuring it fits over your knuckle.
  4. Use a ruler to measure the distance between the marks
  5. Refer to the ring sizes chart below to compare your measurement to the standard sizes ("Circumference" column)

Method #3: The Finger Circumference (Use a Ring Sizer)

If you're in doubt about the accuracy of the first technique, you can purchase your own ring-measurement tool. Ring sizers are plastic or metal tools that help you perform an accurate measurement of the circumference of the finger.

To use a plastic belt ring sizer:

  1. Wrap it around the base of your finger where you would like the ring to fit and push the end of the ring sizer through the buckle, so it forms a ring shape. Adjust the tightness until you have a comfortable fit.
  2. Mark the point on the ring sizer where it meets, ensuring it fits over your knuckle.
  3. When you have the right fit, read the accurate ring size indicated by the arrow.
  4. Refer to the ring size chart below to compare your measurement to the standard ring sizes ("Circumference" column)

The ring sizer set is an easy way to find your perfect size. The metal rings on a loop and corresponding ring sizes emblazoned against them, make the measuring process a breeze. All you need to do is to figure out which ring fits your finger comfortably. Then make a note of the size marked on it.
How to measure ring size with an existing ring and ruler

Method #4: The Ring Diameter Way (Use a Printable Ring Sizer or a Ruler)

If you have an existing ring that fits well, you can use it to find out your ring size. It is also a great way to secretly determine someone else's size if you are purchasing the ring as a gift. All you need is a ruler and some free time.

  1. Measure the inside circumference of a ring your already own
  2. Refer to the " Inside Diameter" column in the chart below to find your corresponding ring size

There are several options online for printable ring sizers. Or you can download ours and print it out on A4 paper at 100% scale. Then line up the inside edge of an existing ring with the inside edge of the circles on the paper to find the circle that matches your size.
