BMI for 178 cm Women
Instant answer: Women who are 178 cm (5'10") tall have a healthy BMI weight range of 58.6–78.9 kg (129–174 lbs).
Public-health guidelines place the ideal weight for 178 cm tall adults at 58.6–78.9 kg, equivalent to a BMI between 18.5 and 24.9.
Gender-specific context
Hormonal phase, pregnancy, and menopause all shift weight distribution. A woman 178 cm tall may comfortably move several kilograms within the healthy band over a lifetime.
Weight for each BMI category at 178 cm
Every figure below is derived from the BMI formula (weight in kg ÷ height in m²) at a height of 178 cm (5'10"), using the same calculation engine as the calculator on this page.
| WHO category | BMI | Weight (kg) | Weight (lbs) |
|---|---|---|---|
| Underweight | < 18.5 | under 58.3 kg | under 129 lbs |
| Normal weight | 18.5 – 24.9 | 58.6–78.9 kg | 129–174 lbs |
| Overweight | 25.0 – 29.9 | 79.2–94.7 kg | 175–209 lbs |
| Obese Class I | 30.0 – 34.9 | 95.1–110.6 kg | 210–244 lbs |
| Obese Class II | 35.0 – 39.9 | 110.9–126.4 kg | 244–279 lbs |
| Obese Class III | ≥ 40.0 | 126.7 kg and above | 279 lbs and above |
The BMI formula (and how this site rounds it)
Metric: BMI = weight in kilograms ÷ (height in metres)². Imperial: BMI = 703 × weight in pounds ÷ (height in inches)². Both produce the same number; 703 is the unit-conversion constant.
Worked example. An adult weighing 60 kg at 165 cm: 165 cm = 1.65 m, and 1.65² = 2.7225. 60 ÷ 2.7225 = 22.0, which is normal weight. The imperial route (132 lbs, 65 in) gives 703 × 132 ÷ 65² = 22.0 — the same value within rounding.
Rounding rules used here: BMI is rounded to one decimal place, and the WHO category is assigned from that rounded value. Weights in kilograms are shown to one decimal; pound equivalents are rounded to the nearest whole pound using 1 kg = 2.20462 lbs. Height in feet and inches is rounded to the nearest inch.
| Weight | Height | BMI | WHO category |
|---|---|---|---|
| 70 kg (154 lbs) | 175 cm (5'9") | 22.9 | Normal weight |
| 60 kg (132 lbs) | 165 cm (5'5") | 22.0 | Normal weight |
| 85 kg (187 lbs) | 180 cm (5'11") | 26.2 | Overweight |
| 55 kg (121 lbs) | 160 cm (5'3") | 21.5 | Normal weight |
| 78 kg (172 lbs) | 170 cm (5'7") | 27.0 | Overweight |
| 95 kg (209 lbs) | 185 cm (6'1") | 27.8 | Overweight |
What BMI does not measure
BMI uses only height and weight. It is a screening ratio, not a body-composition measurement or a diagnosis. Specifically, BMI cannot tell you:
- Muscle versus fat. Weight from muscle and weight from fat count identically, so trained athletes are frequently classified as overweight at healthy body-fat levels.
- Where fat is stored. Visceral (abdominal) fat carries far more cardiometabolic risk than subcutaneous fat, and BMI is blind to the difference. Waist circumference — under 94 cm for men, 80 cm for women — adds that missing signal.
- Bone density or hydration. Both shift scale weight without changing fat mass.
- Age-related body change. Muscle mass declines with age (sarcopenia), so the same BMI at 70 usually represents more fat than at 25.
Where adult BMI does not apply at all: children and teenagers under 18 (who need age-and-sex percentile charts, not adult thresholds), pregnant and breastfeeding women, people with significant oedema or ascites, and adults with limb loss or skeletal dysplasia. Population-specific cut-offs are also lower for South and East Asian adults, where the WHO recommends action points at BMI 23 and 27.5.
Frequently asked questions
What is a healthy BMI for women at 178 cm?
Women who are 178 cm tall have the same BMI healthy range as everyone else (18.5–24.9), corresponding to 58.6–78.9 kg.
What should a woman weigh at 178 cm?
A healthy weight is anywhere in the 58.6–78.9 kg range. Active women often settle in the middle portion of this band.
Is BMI different for women?
The BMI calculation and category thresholds are the same regardless of sex. What differs is the body-fat percentage that corresponds to the same BMI — women have a typical healthy body-fat range of 21–33%.
