For optimal comfort and accurate tracking, a Fitbit should fit loosely enough to move back and forth on your wrist during daily wear, and higher and secure (but not too tight) during exercise.
General Fit for Daily Wear
According to the guidelines, when you're wearing your Fitbit throughout the day for general tracking, the band should not be tight against your skin.
- Loose Enough: The recommended fit is one that allows the band to move back and forth on your wrist. This ensures comfort and allows your skin to breathe underneath the device.
Fit During Exercise
When you engage in physical activity, the recommended fit changes slightly to ensure better data accuracy, especially for heart rate tracking.
- Higher Position: During exercise, you should consider moving the band higher on your wrist. Specifically, place it approximately 2-3 finger widths above your wrist bone.
- Secure, Not Tight: While moved higher, the band should be secure to maintain consistent contact for sensors, but it is crucial that it is not too tight. It should feel stable without restricting circulation or causing discomfort.
Key Considerations for an Ideal Fit
Achieving the right fit for your Fitbit is important for both comfort and the performance of its tracking features.
- Comfort: A band that is too tight can cause irritation, restrict blood flow, and leave marks on your skin. A band that is too loose during activity might slide around and affect readings.
- Accuracy: For features like heart rate monitoring, a consistent, close (but not overly tight) contact with the skin is needed. Positioning the device correctly during exercise helps achieve this.
- Skin Health: Wearing the band loosely for daily activities allows air circulation and reduces the risk of moisture buildup and skin irritation.
Finding the perfect fit might require a little adjustment, but focusing on these guidelines will help ensure a positive experience with your device.
