Blood Pressure Checker and BP Chart
Enter your systolic and diastolic blood pressure to see whether it is normal, high-normal or high, with the usual target for people with diabetes. It is free and nothing is stored.
This tool is for education only. It is not a diagnosis or a treatment plan. Never stop or change a prescribed medicine without your doctor. Nothing you enter is stored or sent anywhere.
Blood pressure categories
| Category | Systolic (top) | Diastolic (bottom) | |
|---|---|---|---|
| Low | Under 90 | or | Under 60 |
| Normal | Under 130 | and | Under 85 |
| High-normal | 130 to 139 | or | 85 to 89 |
| Grade 1 hypertension | 140 to 159 | or | 90 to 99 |
| Grade 2 hypertension | 160 or more | or | 100 or more |
Categories follow the International Society of Hypertension 2020 guideline. When the two numbers fall in different categories, the higher category applies.
BP chart by age
Older charts show a higher "normal" blood pressure with age. Current guidelines do not: targets do not rise just because you are older, and a reading of 140/90 or more in an adult of any age is worth discussing with a doctor. Many doctors aim for under 130/80 in people with diabetes.
How to measure at home
- Sit quietly for 5 minutes with your back supported and feet flat.
- Rest your arm at heart level with the cuff on bare skin.
- No coffee, smoking or exercise for 30 minutes before.
- Take two readings a minute apart on 3 to 7 days and share the average with your doctor.
Common questions
Under 130/85 mmHg is normal. A common target for people with diabetes is under 130/80; your doctor sets yours.
Both. If they fall in different categories, the higher category is used.
No. Stress, pain and a rushed measurement raise a reading. Hypertension is diagnosed on repeat readings.
If it is 180/110 or higher and stays high after 5 minutes of rest, or with chest pain, breathlessness or a severe headache, seek emergency care.
Many doctors aim for under 130/80 in people with diabetes. Ask your doctor for yours.
