Discovering the correct ring size when choosing an engagement ring can be difficult, but with a bit of creativity and the use of an appropriate ring size chart, slipping the ring on the bride-to-be’s finger will be easy and comfortable.

Finding Ring Size Charts

Most jewelers have ring size charts available as well as assorted tools to determine ring size either from an existing ring or by measuring the appropriate finger. If the engagement ring is a surprise, however, taking your beloved into a jewelry store and asking to measure her finger is not the most subtle or secretive approach. There are a number of ring size charts available online, either to convert measurements or to compare against existing rings.

When you locate a suitable ring size chart, be sure that its measurements are appropriate. Different countries often calculate ring sizes differently, and even a small adjustment could make the ring too loose or too tight for the best fit. Check table conversion labels for appropriate countries and measurements, and if you choose to print a ring comparison chart (a set of measured circles you can compare existing rings against to gauge size), be certain that your printer is not resizing the chart in any way.

Using a Ring Size Chart

The two types of ring size charts are used differently: the most common variety is simply a table of measurements that converts the circumference of the finger to the appropriate ring size. To find the circumference of the finger, cut a strip of paper no more than one-quarter of an inch wide (any wider may distort measurements because most rings are thin) and wrap it comfortably around the finger where the ring will rest. Mark on the paper where the circle is complete, and then measure that distance to compare to the figures in the ring size chart. Instead of paper, you can also use string or wire, as long as you follow the steps carefully to obtain an accurate measurement. Also be sure that the paper or string is loose enough to fit comfortably over the knuckle so the ring can be put on and taken off easily. To use this type of ring size chart with an existing ring, slide the ring onto a taper candle or carrot, mark where it comes to rest easily, and measure the circumference at that point.

The second type of ring size chart is a series of graduated circles that represent different ring sizes. Choose a ring that fits well (perhaps borrowing it while your intended is in the shower or otherwise unaware of your using it), and lay it against the paper to compare it to the printed circles. The circle that most closely matches the ring will be the ring size. When using this type of ring size chart, however, be sure that you are comparing the inner surface of the ring to the printed circles rather than the outside surface: that additional space could make the ring far too loose.

Tips for Measuring Ring Size

Fingers can change size throughout the day, and proper measurements are crucial to obtain an accurate size for the engagement ring. For the best measurements, follow these tips:

• If the finger joints are prominent, either measure the widest part of the finger or use a printed comparison chart with a well-fitting ring for the best measurement.
  
  
• Fingers change size according to temperature, time of day, and even humidity. For the best fit, take measurements at room temperature (not after showering, being outdoors in the winter, vigorous exercise, etc.) and toward the end of the day (when the fingers are typically largest).
  
  
• A woman’s finger size can change during her menstrual cycle, growing slightly larger if she retains water. Be careful not to obtain a measurement during that time, which could result in a ring that will be loose most of the month.
  
  
• If the measurement is between two potential sizes, choose the larger size to be sure it will fit.
  
  
• Measure in millimeters for a more accurate size.
  

Accurate ring size measurements are especially crucial for more elaborate rings such as eternity rings or bridal sets, which are difficult and expensive to resize because of their intricacy. Furthermore, if the ring will be engraved, appropriate sizes are also important.
