The internet is continuing to make it easier to never have to leave the comfort of your home for food, exercise, or getting groceries, why shouldn't that be the case when it comes to measuring your ring size before ordering jewelry online. You could go to a jeweler, but that doesn’t really fit with the whole doing it from home thing you’ve got going on.

According to expert jewelers, “Your ring should fit your finger comfortably; snug enough so that it will not fall off, but loose enough to slide over your knuckle with some resistance.”

Before you sit down to measure your ring size, there are a few things you should keep in mind:

1. Consider your knuckle. If you know your knuckle is on the larger side, you should order half a size bigger than what your finger alone indicates otherwise you won’t be able slide a ring into the right place.

2. Ensure accuracy with multiple tries. jewelers advise measuring your finger three to four different times because the size actually fluctuates depending on temperature, it tends to be smaller the colder you are and more swollen if you’re overheated.

Here is three common and easy ways to measure your ring size at home. Using string, a ring size chart, and a ring sizer, so you can get the right piece of jewelry that you want from online.

1. Using String or Floss to Measure Your Finger

You can measure your ring size using either string or, something more common in your home like floss. Take one of these measurement tools and wrap it around the base of your finger, marking where the string or floss meets the start with a pen. Then, line that up with a ruler and write down its length in millimeters.

With standard ring sizes, every half a size matches up to a 0.4 millimeter increment, starting with size 3 equaling 14.1 mm, size 3.5 equal to 14.5 mm, size 4 equal to 14.9 mm, and so on. The most common ring sizes for women are 6 (16.5 mm), 6.5 (16.9 mm), and 7 (17.3 mm). 

There is one thing to consider with this method: String and floss can stretch, so try not to force your measuring tool too tight because you may be forcing your ring size smaller than what it will be with a more rigid material.

2. Place a Ring You Already Own On A Ring Size Chart

You can measure your ring size using a piece of jewelry that you already own and know fits you. Print out a true-to-size ring size chart, like this one on Bubbly Belle’s site, and place your ring on the circles until you find the one that matches up with the inside circumference of your ring.

The ring size chart should tell you how many millimeters/centimeters the matching circle is as well as what ring size that measurement correlates to.

3. Purchase Your Own Ring Sizer

If you’re worried about one of those two methods not guaranteeing accuracy, you can purchase your own ring measurement tool. They aren't too expensive, and there are many options online so you don’t have to leave your house to get this step accomplished, which is the whole point of this article. 

The best reviewed ring sizing tools can be found on Amazon and fall into two categories: a thin measuring tape or a keyring lined with a variety of sizes of rings.

A top-rated ring sizer for rings made by Mudder lets you try on sizes 1 through 13, including half sizes ($7 on amazon.com), while Peacock Jewel’s top-rated measuring tape works like a mini belt, sliding a plastic arrow marker into place to measure your ring size ($5 on amazon.com).
