A well-fitted ring is just as important as its design.
At Moissanite Room, every ring is handcrafted to be worn comfortably and confidently. Use this guide to determine your ideal ring size before placing your order, ensuring your jewellery feels secure and comfortable from the moment it arrives.
Taking a few extra moments to measure correctly will help you choose the most comfortable ring size and ensure the best fit.
Finger size naturally changes throughout the day and with the weather. Measure when your hands are at a normal room temperature for the most accurate result.
Fingers are generally slightly larger during the evening, making this the ideal time to measure your ring size.
Repeat the measuring process two or three times. Consistent measurements provide the most reliable size.
Wider bands usually fit more snugly than slim designs. Choosing a slightly larger size often provides greater comfort.
The same finger on opposite hands may differ slightly in size. Always measure the finger that will wear your ring.
Compare your finger measurement with the chart below to determine your recommended US ring size.
| US Size | Inside Diameter | Finger Circumference |
|---|---|---|
| 4 | 14.8 mm | 46.8 mm |
| 5 | 15.7 mm | 49.3 mm |
| 6 | 16.5 mm | 51.9 mm |
| 7 | 17.3 mm | 54.4 mm |
| 8 | 18.1 mm | 57.0 mm |
| 9 | 18.9 mm | 59.5 mm |
| 10 | 19.8 mm | 62.1 mm |
| 11 | 20.6 mm | 64.6 mm |
If your measurement falls between two sizes, choosing the larger size generally provides a more comfortable fit.
Follow these simple steps to accurately measure your finger and determine the correct US ring size.
Wrap a thin strip of paper or a flexible measuring tape around the base of the finger where the ring will be worn.
Mark the point where the ends overlap without pulling the paper too tightly around your finger.
Lay the strip flat and measure the length in millimetres using a ruler.
Compare your measurement with the Ring Size Chart above to determine your recommended US size.
If you already own a ring that fits comfortably, measuring its inside diameter is one of the easiest and most accurate ways to determine your ring size.
Simply measure the inside edge of the ring in millimetres and compare it with the Ring Size Conversion Chart above to find the closest match.
Always measure the inside diameter of the ring, not the outer edge, for the most accurate result.
