How to Measure Your Correct Ring Size

Thank you for choosing YophieMade for your ring purchase. To ensure that you find the perfect fit, please follow the instructions below on how to measure your ring size.

Choose a Piece of String: Use a piece of string instead of paper or tape for a more accurate measurement.
Wrap the String Around Your Finger: Gently wrap the string around the finger you wish to measure. Ensure it is neither too tight nor too loose.
Mark the String: Mark the point where the ends of the string meet with a pen or marker.
Measure the String: Lay the string flat and measure the length from the starting point to the mark with a ruler. Note the measurement in millimeters or inches.
Determine Your Ring Size: Refer to the ring size chart below to convert the measurement to your corresponding ring size.

This ring is made from five individual bands that can unfold into a beautiful astronomical sphere pendant. When closed, it becomes a sleek, elegant ring. My idea for this design came from a 16th-century antique ring, now kept at the Swedish History Museum (Statens Historiska Museer). The original was a symbol of wonder, showing the movement of stars and planets. For a closer look, refer to the prototype and our video demonstration on how to open the ring.

To make it better for everyday wear, I carefully adjusted the thickness to about 2.5mm—light, comfortable, and perfect for those who love both beauty and play. Opening and closing it is such a satisfying feeling, and I hope it brings you the same joy. This is my final and best version, and I truly believe it’s one of the finest available.

This elegant piece is crafted from high-quality solid sterling silver and brass. It measures around 4–4.5 mm wide and 2.5 mm thick. You can also wear it as a necklace by adding a matching chain. The chain is made from sterling silver, with a length of 18 inches (about 50 cm).
