Width of the Ring Band

For rings with a wider band, we recommend choosing a size slightly larger than your usual size. When wearing both a wedding ring and an engagement ring together, if the total width is wider than 4mm or 5mm, it's best to choose a larger size.

Weather and Time of Day

Finger size contracts in cold weather and expands in hot weather, so a size measured in winter may differ from one measured in summer. Humidity and altitude can also affect ring size, so these factors should be considered when choosing a size.

Fit when Wearing

While an ideal ring size is one that fits snugly, if it's too tight, it can cause problems such as restricted circulation. Choose a size that can pass over your knuckle but won't slip off during daily activities.
