Tips for Accurate Measurement

• Measure your finger at the end of the day, as fingers tend to swell.
• Avoid measuring in extreme hot or cold conditions, which can alter finger size.
• Ensure the ring fits snugly but comfortably over your knuckle.

If you're purchasing a ring as a gift, use a ring your recipient already wears on the same finger to guide your choice.
