Easy tips to measure your ring size at home

Ring sizer card is available now.

Similar to shoe or clothing sizes, ring sizes can vary between different countries and brands.

OLIVIA YAO JEWELLERY uses the "international ring size," which is a standard commonly used in Taiwan. However, it's important to note that in Hong Kong and China, they may also refer to their ring sizes as "international ring size," so be aware of potential discrepancies with the Taiwanese international ring size.

There are multiple methods for ring measuring. When purchasing a ring, it's best to use the measurement standards provided by the brand for the most accurate and reliable results.

3. Measure your ring size using the "OYJ Ring Sizer Card" developed by OYJ.

After multiple size calibrations, this exclusive ring size card is now available for purchase and comes with a complimentary $100 shopping voucher.



 


The diameter unit of the inner ring size must be as small as 1mm to be precise.
 

We created a true-to-size ring sizer card for you to measure your ring size precisely with ease. Our ring sizer is made with heavy card board which is a reusable/durable material.

To make sure you get the best possible fit, we advise to measure your ring size at the end of the day when your fingers are warm. Finger size changes depending on the time of day and the weather, your fingers are actually smaller during cold weathers and bigger during hot weathers. The right fit should feel tight enough so it won’t fall off, but loose enough to slide over your knuckle with relative ease.

Reminder: When shopping for wide rings and chainrings, we recommend getting a size larger than your measurement for a more comfortable fit.

(for example, when measuring the index finger with a sizer card, normally the result is international size 9. If you are buying a general thin ring, choosing size 9 is perfectly fine. But if you are buying a wide ring or chainring, size 10 will be better. )
