How To Measure Ring Size

How To Measure Ring Size

Measuring ring size can be a daunting task, but it is essential to ensure that you purchase a ring that fits comfortably on your finger. At San Jose Jewelers, we believe that choosing the right ring size is of utmost importance, which is why we have prepared this comprehensive guide to help you measure your ring size accurately.

Why is it Important to Measure Ring Size?

Purchasing a ring that is too tight can be uncomfortable and may even affect blood circulation in your finger. Alternatively, buying a loose ring can cause it to slide off your finger and become easily lost. Therefore, measuring ring size is critical to ensure you purchase a ring that fits snugly on your finger and is comfortable to wear.

5 Ways to Measure Ring Size

There are various methods that you can use to measure your ring size. Here are the five most common ways:

Measure With String or Strip of Paper

This method involves wrapping a strip of paper or string around your finger and measuring the circumference. Use a ruler or measuring tape to determine the length in millimeters. Ensure you are using a high-quality string that will not stretch when measuring.

Use a Ring Sizer

A ring sizer is a small tool that measures your finger's circumference in millimeters. It is an excellent option when shopping for rings online. At San Jose Jewelers, we offer a free ring sizer kit to our customers.

Use a Printable Ring Size Chart

Printable ring size charts are readily available online or at jewelry stores. Simply measure the inner diameter of your current ring and match it to the size chart.

Visit a Jewelry Store

A jeweler has experience in measuring ring size, making it an excellent and reliable option. Simply visit the San Jose Jewelers store, and one of our experienced sales associates will measure your ring size.

Measure Using Ring Size Apps

Several ring size apps are available on app stores, where you can measure your ring size via your mobile phone's camera. However, this is the least preferred method and should only be used as a guide.

Tips For Measuring Ring Size

  • Measure your ring size when your fingers are at their standard size, usually in the evening.
  • If your knuckles are significantly larger than the base of your finger, measure your ring's size over the knuckle and the base of your finger to ensure a comfortable fit.
  • If your ring size falls between two sizes, always opt for the larger size to ensure a comfortable fit.
  • Remember that your ring size can fluctuate in different weather conditions, such as heat and cold.


Measuring ring size can be a straightforward task when you have the right tools and techniques. At San Jose Jewelers, we recommend measuring your ring size before purchasing a ring to ensure a comfortable fit and avoid any potential discomfort or loss. We hope that this guide has provided you with all the information you need to measure your ring size accurately. Shop our full selection of jewelry today!
