When placed on the finger, the ring should be snug enough not to fall off, but loose enough to slip off when you want to remove it.

Finger measurement varies depending on the time of day and the weather. For best results, measure your finger:
- At the end of the day or when your finger is warm (fingers are thinner in the early 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 ordering from abroad, you can determine the size of your ring according to your country by using the table above, matching the Portuguese and international measurements.
