Blood Pressure 177 Over 60–160: Which Are OK?

With an upper value of 177, the answer depends on your lower number. Here are all readings, sorted by what they mean.

On its own, a systolic (upper) value of 177 mmHg is Hypertension stage 2 by the international categories (2023 ESH guideline) and Stage 2 hypertension under the 2025 AHA/ACC guideline. The worse of your two numbers decides the category, so a raised diastolic (lower) value moves a 177 reading up: from 177/110 it counts as stage 3. Readings below 177/117 have a pulse pressure above 60 mmHg — a wide gap that is common after 60 and worth mentioning to your doctor.

What to do with a reading of 177 over …

Measure at home for 7 days, morning and evening, and take the average to your doctor. A home average of 135/85 or more confirms high blood pressure. From 177/110 the lower number makes it stage 3: sit quietly for 5 minutes and measure again; if it stays at 110 or higher, contact a doctor the same day, and call 911 (US) or your local emergency number with chest pain, shortness of breath, back pain, numbness or weakness, vision or speech problems, confusion or a severe headache. Keep your readings in a free blood pressure log and read how to measure correctly.
