Blood pressure chart
Use the blood pressure chart below to see what your blood pressure means. The blood pressure chart is suitable for adults of any age. (The level for high blood pressure does not change with age.)
Blood pressure readings have two numbers, for example 140/90mmHg.
The top number is your systolic blood pressure. (The highest pressure when your heart beats and pushes the blood round your body.) The bottom one is your diastolic blood pressure. (The lowest pressure when your heart relaxes between beats.)
The blood pressure chart below shows ranges of high, low and healthy blood pressure readings.
