At a glance
The Healthy Range at 5 Foot 5
A woman who is 5 foot 5 (65 inches, or 165.1 cm) has a healthy weight range of about 111 to 150 pounds. That range comes from the WHO definition of a normal BMI (18.5 to 24.9): 18.5 × 1.651² ≈ 50.4 kg (111.2 lb) at the low end and 24.9 × 1.651² ≈ 67.9 kg (149.6 lb) at the high end.

Where the Underweight Line Falls
At this height, the underweight threshold is about 111 lb. Weighing less than that puts BMI below 18.5, and below about 101 lb the reading drops under 17 into moderate thinness territory. The calculator above shows your exact BMI, category, and the healthy weight range for your height.
Context Matters
BMI categories are population-level screening tools for adults 18-65. Muscle mass, frame size, and age all shift what weight is healthiest for an individual, so treat the range as a starting point rather than a verdict.
Frequently Asked Questions
Is 130 pounds a good weight for a 5'5" woman?
Yes. At 5 foot 5, 130 pounds gives a BMI of 21.6, which sits comfortably in the middle of the normal range (18.5-24.9).
Does age change the healthy weight range at 5'5"?
The standard BMI categories are designed for adults 18-65, so the 111-150 lb range applies across that span. Elderly adults may use different reference data.
What if I am muscular at 5'5"?
Muscle is denser than fat, so a very muscular woman can weigh over 150 lb and still be lean. BMI cannot distinguish muscle from fat.
Is 105 pounds underweight for 5'5"?
Yes. At 105 lb the BMI is 17.5, which falls in the mild thinness (underweight) category.
