Your “ideal weight” isn’t based on age alone—it mainly depends on height, sex, and body composition. Age matters a little (because muscle changes over time), but height is the key factor.
📏 Simple and widely used guide: BMI range
A healthy Body Mass Index (BMI) is usually 18.5 to 24.9.
✔️ How to estimate your healthy weight range:
Healthy weight (kg) = BMI × height (meters)²
📊 Example (quick reference)
If your height is:
- 150 cm (1.50 m) → healthy weight: 42 – 56 kg
- 160 cm (1.60 m) → healthy weight: 47 – 64 kg
- 170 cm (1.70 m) → healthy weight: 54 – 72 kg
- 180 cm (1.80 m) → healthy weight: 60 – 81 kg
👤 Age factor (important clarification)
- Teens/children → use growth charts, not BMI alone
- Adults (18–65) → BMI range works well
- Older adults → slightly higher weight can still be healthy if muscle is good
⚠️ Limitations of “ideal weight”
BMI doesn’t consider:
- Muscle (athletes may weigh more but be healthy)
- Fat distribution
- Bone structure
So two people with the same height can have different healthy weights.
