How to Measure Ring Size Correctly?

Here are a few tips from me on how to find the right ring size.

How to measure your ring size without any tools

Do you already have a ring that fits? Then simply measure the inner diameter with a ruler – from inner edge to inner edge. Multiply this value by 3.14, and you have your ring size. For example, an inner diameter of 17.5 mm corresponds to size 55.

No suitable ring at hand? A narrow strip of paper will also work: wrap it around your finger, mark where the ends meet, and measure the length with a ruler. This length in millimeters is directly your ring size.

Honestly: these methods are a good first indicator, but not 100% accurate. Paper stretches differently than metal, and a ruler never measures quite as precisely as a professional ring sizer. For most people, this is perfectly sufficient – but if you want to be absolutely sure, use a ring sizer or have yourself measured by a jeweler near you.

Temperature differences depending on

Time of day

Depending on the temperature, your fingers may be slightly smaller or larger in circumference. Mild water retention, which increases throughout the day, can also cause them to swell slightly. That’s why it’s best to measure in the evening. Then the ring won’t be too small.

Differences in ring sizes

left and right hand

Your fingers on your left and right hands are usually completely different. Therefore, please measure exactly on the finger where you want to wear the ring.
