Important Tips for Accurate Measuring:

  • Measure at room temperature, as cold fingers shrink and warm fingers swell.

  • Avoid measuring in the morning or after exercise, flights, or drinking lots of fluids, as fingers may be swollen.

  • If you're between sizes, go for the larger size for comfort.

  • Wider rings need a bigger size. Move up one size for a wider ring.

For the most precise results, consider purchasing a ring sizer online, as they are inexpensive and highly accurate.
