Helpful Tips

• Measure your finger at the end of the day when it's at its largest
• Avoid measuring when your hands are cold as fingers shrink
• Consider the width of the ring - wider bands require larger sizes
• If between sizes, choose the larger size for comfort
• Different fingers may require different sizes
