How to Calculate Ideal Weight for 155cm

1

Convert height to inches

155 cm ÷ 2.54 = 61 inches (5'1")
2

Inches above 5 feet (60 in)

61 − 60 = 1 inches above 5ft
3

Apply Devine formula (most used)

Men: 50 + (2.3 × 1) = 52.4 kgWomen: 45.5 + (2.3 × 1) = 47.9 kg
4

Verify with BMI

BMI = 52.4 ÷ (1.55)² = 22.4 ✅ Within healthy range

About the 4 Medical Formulas

Hamwi (1964)

The earliest formula, developed by Dr. G.J. Hamwi in 1964 for clinical nutrition. Published via the American Diabetes Association .

Devine (1974)

Developed by Dr. B.J. Devine in 1974 for drug dosage calculations. It later became a common reference-weight estimate.

Robinson (1983)

Developed by Dr. J.D. Robinson in 1983 using regression analysis of Metropolitan Life Insurance data. Gives values close to Devine.

Miller (1983)

Developed by Dr. D.R. Miller in 1983 using updated Metropolitan Life tables. Typically produces the highest values.

Why Does Ideal Weight Differ Between Men and Women?

At 155 cm the four formulas give men about 3.5 kg more than women, because each formula uses different constants for men and women, derived from historical height–weight data (on average men carry more lean and bone mass). The BMI-based healthy range is the same for both sexes at the same height.

What is the difference between Devine, Robinson, Miller and Hamwi formulas for 155cm?↓
For men at 155cm: Devine = 52.4 kg, Robinson = 53.9 kg, Miller = 57.6 kg, Hamwi = 50.8 kg. For women: Devine = 47.9 kg, Robinson = 50.7 kg, Miller = 54.5 kg, Hamwi = 47.8 kg. Using the average of all four gives the most balanced estimate.
How do I reach my ideal weight at 155cm?↓
To reach the ideal weight (53.7 kg for men, 50.2 kg for women) at 155cm: calculate your daily calorie needs using a TDEE calculator, then create a deficit of no more than 500 calories/day to safely lose 0.5 kg per week. Incorporate strength training 3×/week to preserve muscle mass.
