Normal vital signs chart
The five numbers doctors check first, what normal looks like, and which you can check at home.
Reviewed by Pulselens editorial · Updated 27 September 2026
Vital signs are the body's basic measurements. Normal ranges for a resting adult are below; your own usual numbers matter just as much.
| Vital sign | Normal adult range | How to check at home |
|---|---|---|
| Heart rate | 60–100 bpm | Wrist pulse, watch, or face-camera scan |
| Respiratory rate | 12–20 breaths/min | Count for 60 seconds, or face-camera estimate |
| Blood pressure | Below 120/80 mmHg | Validated upper-arm cuff |
| Oxygen saturation (SpO₂) | 95–100% | Fingertip pulse oximeter |
| Temperature | About 36.1–37.2 °C | Thermometer |
Why one reading is not enough
Coffee, stress, talking, recent activity and poor sleep shift every vital sign. Measure at the same time of day, seated and rested, and compare with your own trend.
What a camera can and cannot do
Face-camera methods (rPPG) can estimate heart rate well in good light and, less reliably, breathing. There is no validated way to read blood pressure or oxygen from a face video, so Pulselens never shows those as camera numbers.
