Blood Pressure 126 Over 40–117: Which Are OK?

With an upper value of 126, the answer depends on your lower number. Here are all readings, sorted by what they mean.

On its own, a systolic (upper) value of 126 mmHg is Normal by the international categories (2023 ESH guideline) and Elevated under the 2025 AHA/ACC guideline. The worse of your two numbers decides the category, so a raised diastolic (lower) value moves a 126 reading up: from 126/85 it counts as high normal, from 126/90 it counts as stage 1, from 126/100 it counts as stage 2, from 126/110 it counts as stage 3. Readings below 126/66 have a pulse pressure above 60 mmHg — a wide gap that is common after 60 and worth mentioning to your doctor.

Blood pressure chart with the row for an upper value of 126: which lower values are ideal, normal, high normal or hypertension

Normal 126/40 to 126/84

↓ = the lower number is below 50: these readings count as normal by the upper number, but the low lower number needs checking — see each page.

High normal 126/85 to 126/89

Hypertension stage 1 126/90 to 126/99

Hypertension stage 2 126/100 to 126/109

Hypertension stage 3 126/110 to 126/117

What to do with a reading of 126 over …

Normal internationally, though above the ideal of under 120 (the US calls it elevated). Re-check once or twice a year and keep an eye on salt, weight and exercise. From 126/110 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. A lower number below 50 (from 126/49 down) is clearly low: measure again, and if it is confirmed or you feel dizzy, faint or confused, contact a doctor the same day. Keep your readings in a free blood pressure log and read how to measure correctly.
