When put on your finger, the Ring should be comfortable so that it doesn't fall off, but loose enough to slide off when you want to take it off.

The measurement of the finger varies according to the time of day and the weather. To get 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.

For the most 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 the size of your Ring according to your country using the table above, matching the Portuguese measurement to the international one.
