Is 140 over 90 high blood pressure?
Yes, 140 over 90 counts as high blood pressure. 140/90 is the level most guidelines call stage 2 hypertension in the US system, or grade 1 in the European one. One reading does not make the diagnosis, but it does start the conversation.
Measure properly for a week: seated, five quiet minutes first, arm supported at heart height, twice a day. Home averages above 135/85 usually confirm it.
Confirmed high blood pressure responds well to treatment, and treating it is one of the best-proven ways to prevent strokes and heart attacks. Do not sit on the number.
See a doctor promptly if
- A reading of 180/120 mmHg or higher with chest pain, breathlessness, weakness on one side, slurred speech, confusion or sudden visual change. This is an emergency
- Blood pressure of 140/90 mmHg or higher in pregnancy, especially with headache, upper abdominal pain, visual disturbance or sudden swelling
- A repeated reading of 180/120 mmHg or higher even without symptoms. This needs same-day medical assessment
- New severe headache, nosebleeds that will not stop, or breathlessness lying flat alongside high readings
- Blood in the urine, or a sharp fall in how much urine you pass, together with high readings
Where your reading sits
| Result | In short | What it means |
|---|---|---|
| Under 120 / under 80 | Normal | Nothing to do but keep checking now and then. This is the range associated with the lowest long-term risk. |
| 120 to 129 / under 80 | Elevated | Not treated with medicine, and the point where salt, weight, movement and alcohol are worth working on. |
| 130 to 139 / 80 to 89 | Stage 1 (US) | Lifestyle first for most people. Medicine enters the conversation if you already have diabetes, kidney disease or established heart risk. |
| 140 to 159 / 90 to 99 | Stage 2 (US), grade 1 (Europe) | 140/90 sits here. A week of home readings averaging above 135/85 usually confirms it, and treatment at this level is one of the best-proven things in medicine. |
| 160 to 179 / 100 to 109 | Grade 2 | Treatment is normally started rather than deferred. Book a proper assessment rather than rechecking for another month. |
| 180+ / 110+ , no symptoms | Same-week care | Recheck after five quiet minutes. If it stays this high, it needs medical attention within days rather than weeks. |
| 180+ / 120+ with symptoms | Emergency | Chest pain, breathlessness, severe headache, vision change, weakness or confusion with a reading this high is an emergency. Call emergency services. |
Home and clinic readings are read against different cutoffs, and home is usually the more honest of the two. Bring the week, not the worst number. Check it against the guidelines.

If you are buying a monitor
Get an upper-arm cuff, not a wrist one, from a validated brand like Omron. Expect $30 to $60. Check the cuff size fits your arm; a too-small cuff reads high.
