Find your ring size: online ring size chart and size conversions by country

Choosing the right ring size is essential—whether it's a gift or a purchase for yourself. A ring that's too tight becomes uncomfortable within the first few hours, while one that's too loose risks slipping off with the slightest movement. The good news is that measuring your finger is simple, and there are several methods depending on what you have on hand. Here are all the ways to find your size, with our Orcha tools to make it even faster.

The Orcha Online Ring Sizer

The most accurate method remains using a physical ring sizer—and we have designed one for you to print at home. Simply download it, print it at actual size (scaled to 100%, without automatic adjustment from your printer), and pass your finger through the circles to identify the one that matches.

Important: Print at actual size ( 100% Scale )

We have also prepared a ring size conversion chart for different countries—France, the United States, the United Kingdom, and Japan—to help you if you are ordering from abroad or if you know your size in another system.

Measuring Your Finger Without a Ring Sizer

If you don't have a ring sizer on hand, two methods provide reliable results. The first involves wrapping a thin strip of paper or a flexible thread around the base of your finger, just above the joint—this is the widest point the ring will need to pass through. Mark where the two ends meet, then measure the resulting length in millimeters: this is your finger's circumference. Divide this number by 3.14 to get the diameter, which you can then compare to our size chart.

The second method is to visit a jeweler: a sizing mandrel (a graduated cylindrical tool) can give you an accurate size in just a few seconds. If you have a trusted jeweler nearby, this is the fastest solution.

When to Measure Your Finger for Reliable Results

The time of day affects the measurement. Fingers tend to swell slightly at the end of the day, in hot weather, or after physical activity. For a size suitable for everyday wear, it is best to measure in the late afternoon at a normal room temperature.

If you are measuring for a gift and are unsure of the size, opt for a slightly larger size rather than a smaller one—it is always easier to have a ring that is too large resized than one that is too small.
