A healthy blood pressure is generally defined as having a systolic pressure (the top number) less than 120 mm Hg and a diastolic pressure (the bottom number) less than 80 mm Hg. This is considered the optimal range for most adults

. More specifically:

• Normal blood pressure: Systolic less than 120 mm Hg and diastolic less than 80 mm Hg

• Elevated blood pressure: Systolic between 120-129 mm Hg and diastolic less than 80 mm Hg

• High blood pressure (Hypertension) Stage 1: Systolic 130-139 mm Hg or diastolic 80-89 mm Hg

• High blood pressure (Hypertension) Stage 2: Systolic 140 mm Hg or higher or diastolic 90 mm Hg or higher

Some sources consider a healthy blood pressure slightly differently, for example under 130/85 mm Hg is also regarded as normal by some guidelines

. Blood pressure can vary with age and individual health conditions, so a doctor may advise on what is healthy for you specifically

. In summary, a typical healthy blood pressure reading is below 120/80 mm Hg, and readings consistently above 130/80 mm Hg are considered elevated or hypertensive and may require medical attention
