You can measure your ring size at home using two methods:

Method 1: Use an existing ring that fits you well. Measure the inside diameter of the ring with a ruler in millimeters (mm) and compare it with our Ring Size Chart.

Method 2: Wrap a piece of paper or string around your finger, mark the point where it overlaps, and measure the length in millimeters. Use this measurement to find your ring size using the Ring Size Chart.

If you don't have a ring to measure, you can still find your ring size by measuring the circumference of your finger. Use a piece of paper or string to wrap around the finger where you'll wear the ring, mark the point where the ends meet, and measure the length in millimeters. You can also visit a jeweler, who can help you determine your ring size with professional tools.

The most accurate way is to measure the internal diameter of a ring that fits you well using a ruler with millimeter markings. For best results, ensure the ring is round and not misshapen. Alternatively, you can visit a jeweler, who can professionally measure your ring size to ensure precise accuracy.

Yes, you can use a string or a piece of paper to measure your finger. Just wrap it around your finger where the ring will sit, mark the point where the string overlaps, and measure the length in millimeters to find your ring size.

Your measurement is correct if the ring fits comfortably—neither too tight nor too loose. It should slide over your knuckle with a little resistance and sit snugly on your finger.

The diameter of a ring is the distance across the inside of the ring, measured straight through the center. It's the internal width of the ring and is typically measured in millimeters. On the other hand, the circumference is the total distance around the inside of the ring. Think of it as the length of the inside edge if you could lay it out flat. Both measurements can be used to determine your ring size, but they refer to different aspects of the ring's shape.

For example, if the internal diameter of your ring is 16 mm, the circumference would be approximately 50.3 mm. Both measurements are useful for determining your ring size, but they refer to different aspects of the ring's shape.

If your measurement falls between two sizes, it's usually best to choose the larger size to ensure comfort, especially if the ring has a wider band.

Yes, your fingers can swell slightly throughout the day due to various factors like temperature and activity level. It's best to measure your finger size at the end of the day when your fingers are likely at their largest.

Yes, our Ring Size Chart includes conversions for US sizes to UK/AUS sizes, along with corresponding internal diameters and circumferences in millimeters.

It's normal for ring size to change slightly over time due to factors like weight fluctuation or aging. If you're unsure of your current size, it's a good idea to re-measure before purchasing a new ring.

To ensure a perfect fit, double-check your measurements using both methods if possible and consult the Ring Size Chart. If you're between sizes, opt for the larger size, and consider the width of the ring band, as wider bands may require a slightly larger size. For the best results, you can also visit a jeweler, who can measure your finger accurately to help ensure the ring will fit perfectly.
