I agree with the other users that the diastolic pressure is important.
In medical practice these days, strict normal is 130/85 or lower, although hypertension
(high blood pressure
) is defined when the pressure is 140/90 or higher (either number, not both). The in-between range is sometimes termed pre-hypertensive.
Essentially, if your pressure is <130/85, then it's OK, assuming you don't have other health conditions like diabetes
disease. One important thing is that the pressure should be a regular reproducible pressure, not a once off reading.
