When placed on your finger, the ring should be comfortable so that it does not fall off, but loose enough to slide off when you want to take it off.

The size of your finger varies depending on the time of day and the weather. To obtain the best results, measure your finger:

— At the end of the day or when your finger is warm (fingers are thinner early in the morning or when the weather is cold);

— Measure your finger size 3 to 4 times to avoid possible reading errors.

To obtain more accurate measurements, you should avoid using string or paper to measure your finger size, as these materials can stretch or twist, distorting the actual measurement. If you are ordering from abroad, you can determine your ring size according to your country, using the table above, matching the Portuguese size with the international size.
