- Tips 3: Measure Close to Your Knuckle: This is where the ring sits,ensure it slides comfortably over your knuckle with a slight resistance.
- Tips 4: Avoid Extreme Conditions: Do not measure your finger in extreme weather,after intense workouts or when you are sick.
- Tips 5: Consider Hand Conditions: Ensure your hand is not swollen,sweaty,or cold during sizing,as these factors can alter your finger size.
