|---|---|---|
| Optimal | < 120 | and < 80 |
| Normal | 120–129 | and/or 80–84 |
| High-normal | 130–139 | and/or 85–89 |

How to read it
The classification (European ESC/ESH guidelines for office measurements) assigns the category based on the worse of the two values. Measure at rest, seated for 5 minutes, and average 2-3 readings.
Warning
A single high reading does not diagnose hypertension: averages over several days are what matter. This tool is informational only and does not replace your doctor.
