Finding the right ring size starts with one accurate measurement. Use either your finger circumference or the inner diameter of a ring that already fits, then compare the result with our official HK, US and JP conversion chart.
Method 1: Measure your finger circumference
- Cut a narrow strip of non-stretch paper or use a flexible measuring tape.
- Wrap it comfortably around the base of the finger. It should pass over the knuckle without feeling loose.
- Mark the point where the ends meet.
- Lay the strip flat and measure the length in millimetres. This is your finger circumference.
Method 2: Measure a ring that already fits
- Choose a ring that fits the same finger.
- Place it on a flat surface.
- Measure straight across the centre from one inner edge to the other inner edge.
- Record the inner diameter in millimetres and compare it with the chart.
Tips for a more reliable fit
- Measure at the end of the day, when fingers are usually at their largest.
- Avoid measuring when your hands are unusually cold or hot.
- Repeat the measurement two or three times.
- If your result falls between two sizes, choose the larger size.
- Wider bands can feel tighter than narrow bands.
How to use Yuuzo adjustable ring sizes
Some Yuuzo rings are listed with an adjustable HK size range. Select a range that includes your measured size and adjust the band gently. Do not repeatedly force the ring beyond the stated range.
