Typical sleep score ranges
- 90–100 excellent sleep
- 80–89 good sleep
- 70–79 moderate sleep
- below 70 poor sleep
How sleep scores are calculated
Wearables often combine sleep duration, sleep stages, movement and heart rate data to estimate sleep quality.
See the Sleep Score Chart.
Core Understanding
Sleep Score is a central wearable metric for sleep, recovery, stress and training. A useful guide should not only define it, but also explain how to use it in practice.
What You Can Learn from This Metric
Depending on the situation, this metric can help you:
- balance strain and recovery better
- avoid overinterpreting wearable data
- read trends instead of single values
- make better health decisions
How to Use It in Daily Life
This metric becomes most useful when viewed regularly and in context with other signals:
- sleep
- stress
- training load
- subjective well-being
