Find Your Perfect Ring Size

 

We’re here to help you determine your ideal ring size to ensure a perfect fit and avoid the need for resizing. Here are the best options to help you get the most accurate measurement:

 

Visit a Local Jeweler

For the most precise sizing, we recommend visiting a professional jeweler who can measure your ring size accurately.

 

Order a Ring Sizer

Another reliable option is to purchase your own MultisizeR ring sizer (Gauga EURO1). It’s a reusable tool, and we offer express shipping (2-4 business days depending on your location). To order, visit Cadi Jewelry’s website.

Bonus: You’ll receive a full refund for the cost of the ring sizer and shipping when you place an order with us!

 

Buying a Ring as a Surprise?

If you're purchasing a ring as a surprise, borrow one of your partner’s rings, slide it down a tapered candle, and measure the circumference where the ring stops. Use this measurement to find the right size using the chart below.



Dos & Don’ts for Measuring Your Ring Size

  • Don’t measure your fingers when they are cold, as this is when they are smallest. The best time to measure is at the end of the day when your fingers are naturally larger. Take at least two measurements for accuracy.

  • If your knuckle is larger than the base of your finger, please leave a note during checkout, and we’ll adjust the sizing to ensure a comfortable fit.

  • Do not use printable ring sizers, as they tend to be inaccurate due to printer settings. A proper ring sizer is essential for precise measurements.


How the Ring Should Fit

A well-sized ring should fit comfortably—snug enough to stay in place but loose enough to slide over your knuckle with ease. Checking your size multiple times ensures the best fit, minimizing the risk of loss and ensuring comfort.

 

Size Adjustments

If you accidentally order the wrong size, don't worry! For most designs, if the difference between the actual size and the ordered size is no greater than half a size, we will offer a free resizing service at no extra cost.
