/ 12 March 2025

Wearing an ill-fitting ring is something we all want to avoid—there’s nothing more annoying than a ring that’s either too tight or too loose.

You certainly wouldn’t want to bring that beautiful diamond engagement ring you just bought in for resizing just because it doesn’t fit right, would you? From discussions on online forums like Pantip, we’ve found that many people face this issue. That’s why we’re sharing an easy and accurate way to find your ring size at home.

With this guide, you won’t need to worry about resizing a ring ever again!

How to Find Your Ring Size from Home

You can contact us to order a “European Standard” ring sizer at a special price. This way, you can accurately measure your ring size at home, using the same standards we follow, ensuring your ring fits perfectly.

Measure Your Current Ring

Choose a ring you wear regularly, preferably on the same finger for which you’re planning to order a new one.
Internationally, engagement and wedding rings are typically worn on the left ring finger.
Place a tape measure or ruler against the ring. Measure the diameter from the inner edge on one side to the inner edge on the opposite side.
If using a tape measure, ensure it’s pulled tight for an accurate reading.
If your measurement falls between two sizes, opt for the larger size. It’s easier to resize a ring down than to make it larger while maintaining its shape.

Measuring a Ring Size That Fits Your Finger

Your ring should feel comfortable—snug enough that it won’t fall off, but not so tight that it causes discomfort.
Ring size can vary based on weather and time of day, so it’s important to measure your finger at the right times:
Measure your ring size in the afternoon, as our fingers tend to shrink in the morning due to cooler body temperature.
Measure your ring size 3 to 4 times to ensure accuracy, especially before placing an order, as weight fluctuations can affect the fit.
Avoid using string or paper to measure, as these materials are elastic and may provide inaccurate results.

Ring Sizer Set: The Most Precise Method of Measuring Your Ring Size

The methods mentioned above are great for those without a ring sizer, but if you want the most precise measurement, using a ring sizer set is the way to go.

We recommend our ring size measurer made from Anodized Zinc Silver Alloy for accuracy. Unlike plastic versions, it won’t irritate your skin or warp, ensuring a perfect fit every time. These rings are perfectly round and will not cut or hurt your fingers.

Measuring the Ring Size of That Special Someone

If you’re planning a surprise, you can ask their friends or family if they know your significant other’s ring size. You could also borrow a ring they already wear on the same finger you intend to buy for, and then measure it using the steps mentioned above.

Standard Asian Ring Sizes

Some ring designs can’t be resized larger, particularly rings with decorative diamonds. Increasing the size can distort the design, though reducing the size may still be possible. This is why it's essential to measure your ring size accurately before placing an order.
