How to Choose the Perfect Ring Size

An ideal ring should be tight enough to stay firmly on your finger, but loose enough so you can turn it effortlessly. Choosing the right size requires taking into account several factors that influence the size of your fingers. Here are our top tips to get it right:

Factors to Consider When Choosing Ring Size

  • Difference between hands: The dominant hand is usually slightly larger than the non-dominant hand. Therefore, a ring that fits perfectly on your right hand may be looser on your left.
  • Variations throughout the day: Fingers change size depending on temperature, humidity and time of day. For example, they expand in the heat and shrink in the cold. Medications, pregnancy or hormonal changes can also cause temporary swelling.
  • Environment and climate: If you are in a place with a different climate than usual (such as on vacation), your fingers could be affected, temporarily altering the size.
  • Seasons of the year: If your body tends to fluctuate depending on the season, consider having specific rings for summer and winter.
  • Ideal time to measure: It is best to measure your finger at the end of the day and when you are resting, as this is when your fingers are at their most stable size.
  • Single fingers: Every finger is a different size, so always measure specifically the one that will wear the ring.
  • In case of doubt: If you are between two sizes, choose the larger size, as it is easier to adjust a large ring than a small one.
  • Bandwidths: Rings with thick bands tend to be tighter, so it's a good idea to select a size up for greater comfort.

Methods for Measuring Ring Size

1. Measure the diameter of the finger
  • Wrap a sewing tape measure around the finger where you will wear the ring and take the measurement in millimeters.
  • If you don't have a tape measure, use a strip of paper or string, then measure it with a ruler.
  • Compare the measurement obtained with a ring size chart in Spain.
2. Measure the internal diameter of an existing ring
  • If you already have a ring that fits you well, measure its inner diameter with a rigid ruler.
  • Another option is to draw the outline of the ring on a piece of paper and measure the resulting circle.
  • Please refer to that measurement in the size chart to make sure it matches your desired size.
  • This method is useful for giving a surprise ring, although it does not consider other factors, such as the weather or daily variations in finger size.
3. Consult a professional jeweler
  • The most accurate way to determine your ring size is to go to a specialist. Jewelers have specific tools, such as the Tatum stick, ring gauges or precision gauges, that guarantee an exact measurement.
  • This option is especially recommended if you are investing in a valuable or personalized ring.

Make sure you always use a reliable method and take into account the natural variations of your fingers. Choosing the right size not only ensures comfort, but also a perfect experience when wearing your ring.
