⚠️ Important Note
These calculations provide general estimates based on mathematical formulas. Individual ideal weight can vary significantly based on muscle mass, bone density, body composition, and other factors. Always consult with healthcare professionals for personalized advice.
How it works
Ideal body weight formulas estimate a healthy target weight from your height and sex. They all share the same shape: a base weight at 5 feet, plus a fixed amount for every inch above that. The Devine formula shown here is the classic, originally created for medication dosing.
Devine ideal body weight
Men: 50 kg + 2.3 kg × (inches over 5 ft) Women: 45.5 kg + 2.3 kg × (inches over 5 ft)
- base
- 50 kg (men) / 45.5 kg (women) at 5 ft tall
- inches over 5 ft
- height above 60 inches
Worked example
- Man, 5’10″ tall (70 inches)
- 70 − 60 = 10 inches over 5 ft
- IBW = 50 + 2.3 × 10
- IBW = 50 + 23 = 73 kg
Ideal weight ≈ 73 kg (≈ 161 lb) by the Devine formula.
Good to know
- There's no single “ideal” — Devine, Robinson, Hamwi, and Miller formulas give slightly different numbers; treat the result as a range, not a target.
- These formulas ignore body composition and frame size, so a muscular person may sit healthily above their “ideal” weight.
- A healthy BMI range (18.5–24.9) for your height is often a more flexible guide than a single ideal-weight figure.

Pertanyaan yang Sering Ditanyakan
How many calories for weight loss?
Create a 500-750 calorie daily deficit for 1-1.5 lbs/week loss. Don't go below 1,200 (women) or 1,500 (men) calories without medical supervision.
What affects calorie needs?
Age, sex, height, weight, activity level, and muscle mass all impact daily calorie requirements. Needs decrease with age and inactivity.
Should I eat back exercise calories?
For weight loss, eat back 50-75% of exercise calories as trackers often overestimate burn. For maintenance or gain, eat back most or all.
How often should I exercise?
The WHO recommends at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity aerobic activity per week.
What is a balanced diet?
A balanced diet includes variety from all food groups: fruits, vegetables, whole grains, lean proteins, and healthy fats.
How much water should I drink?
General recommendation is 8-10 glasses (2-2.5 liters) per day, adjusted for activity level and climate.
How important is sleep?
Sleep is crucial for physical recovery, mental health, and overall wellbeing. Adults need 7-9 hours nightly.
