Here are the normal blood pressure ranges by age based on the search results:

• Newborns up to 1 month: 60-90 mm Hg systolic, 20-60 mm Hg diastolic
• Infants: 87-105 mm Hg systolic, 53-66 mm Hg diastolic
• Toddlers: 95-105 mm Hg systolic, 53-66 mm Hg diastolic
• Preschoolers: 95-110 mm Hg systolic, 56-70 mm Hg diastolic
• School-aged children: 97-112 mm Hg systolic, 57-71 mm Hg diastolic
• Adolescents: 112-128 mm Hg systolic, 66-80 mm Hg diastolic
• Adults (18-39 years): 110/68 mm Hg for women, 119/70 mm Hg for men
• Adults (40-59 years): 122/74 mm Hg for women, 124/77 mm Hg for men
• Adults (60+ years): 139/68 mm Hg for women, 133/69 mm Hg for men
• Older adults (61 and older): 95-145 mm Hg systolic, 70-90 mm Hg diastolic

Its important to note that the new guidelines from the American Heart Association, the American College of Cardiology, and nine other health organizations lowered the numbers for the diagnosis of hypertension (high blood pressure) to 130/80 millimeters of mercury (mm Hg) and higher for all adults. The previous guidelines set the threshold at 140/90 mm Hg for people younger than age 65 and 150/80 mm Hg for those ages 65 and older.
