Finding the perfect fit is essential, not only for comfort but also for a meaningful experience. So, how do you help your customers find the right ring size without the stress?

How to Find Ring Size Without Visiting a Jeweller

Find out how to find ring size with this easy guide.

If your customers are not keen on heading to a jeweler for sizing, there are several ways they can determine their ring size from the comfort of their home. Here’s how to help them determine their ring size without leaving the house:

Use a Ring Size Guide and Chart

One of the easiest ways to measure ring size at home is by using a ring size chart. As a Shopify merchant, you can include a ring size guide on your product pages or send it as part of your confirmation emails. For your customers, this guide will show them how to measure their finger’s circumference (in millimeters) and compare it to the ring size chart to get the exact number for their size.

Here’s a simple chart of common ring sizes and their corresponding measurements that you can use on your site:

Ring SizeDiameter in mmCircumference in mm
4.513.547.8
515.749
5.516.150.3
616.551.5
6.516.952.7
717.353.9
7.517.755.1
818.156.3

How to Measure Ring Size with Paper and a Ruler

Another option is to get creative with a strip of paper. Here’s how to check ring size at home based on circumference using this method:

  1. Cut a piece of paper about 3/8-inch wide (or use a string).
  2. Wrap it around the finger where the ring will sit, just below the knuckle.
  3. Mark the spot where the paper overlaps, creating a snug fit.
  4. Measure the length (in millimeters) from the start of the paper to the mark using a ruler.
  5. Use the chart above to determine ring size based on the measurement.

Measure Ring Size with String or Paper

This simple method will give a reliable diameter measurement to use for finding ring size.

  1. Wrap string or paper around the base of the finger where the ring would sit.
  2. Mark where the ends meet.
  3. Measure the length with a ruler (mm).
  4. Divide by 3.14 (or Pi) to get the diameter of the ring.
  5. Match the diameter with the closest size on a ring size chart.

Which Method Is Best for Finding Ring Size?

While a size chart is a helpful tool, some people prefer using plastic ring sizers or getting professional advice. They can even use an existing ring that fits comfortably. The method chosen depends on comfort level and the resources available. For those looking for more accuracy, it’s always a good idea to try different methods for the best result.

Consider some of these tips, no matter the method!

  • Measure both the base and the knuckle if the finger is wider at the top. Pick a size in between the two measurements.
  • Always measure at the end of the day when fingers are warm and at their largest.
  • Consider measuring 3 to 4 times to ensure accuracy.
  • Keep in mind that the dominant hand usually has larger fingers.

How To Help Customers Find Their Partner’s Ring Size

Finding out how to find ring size for a significant other can be tricky - here are some ways to find it.

If your customers are buying a surprise ring for someone else, help them find the right size with these creative suggestions.

1. Borrow a Ring

Ask your customer to borrow a ring that fits their partner and trace its inside circumference to determine the size.

2. Ask a Friend or Family Member

Suggest that they consult a close friend or family member of their partner who might already know the ring size.

3. Gift a Ring for Another Occasion

They could purchase a less significant ring as a gift, which could reveal the correct size when their partner tries it on.

4. Use a Temporary Setting

If they’re unsure, suggest purchasing a ring with a temporary setting. They can later adjust the size after the proposal.

Remind your customers that the average ring size for women is between size 5 and size 7, so starting with this range can work in most cases. It’s always easier to resize a ring smaller than to make it larger.

Final Thoughts on How to Find Ring Size

Finding the right ring size doesn’t have to be difficult, and with the right tools, you can make the process easier for your customers by providing helpful tools and resources. Whether they are buying for themselves or preparing a surprise for a loved one, knowing how to find ring size will reduce the chances of returns and increase customer satisfaction.
