Several evidence-based formulas estimate ideal body weight. Each was developed for different clinical uses, such as medication dosing and surgical planning. Most produce similar results within 5–10 lbs of each other.
These formulas provide useful guidelines, but your optimal weight depends on muscle mass, bone density, age, and genetics. An athlete may weigh more than these formulas suggest while being very healthy. Use these numbers as a range, not a rigid target.
| Height | Men — Ideal Range | Women — Ideal Range | BMI 18.5–24.9 Range |
|---|---|---|---|
| 5'0" (152 cm) | 106–130 lbs | 100–120 lbs | 95–128 lbs |
| 5'2" (157 cm) | 118–143 lbs | 110–132 lbs | 101–136 lbs |
| 5'4" (163 cm) | 130–155 lbs | 120–144 lbs | 108–145 lbs |
| 5'6" (168 cm) | 142–167 lbs | 130–156 lbs | 115–154 lbs |
| 5'8" (173 cm) | 154–179 lbs | 140–168 lbs | 122–164 lbs |
| 5'10" (178 cm) | 166–191 lbs | 150–180 lbs | 129–174 lbs |
| 6'0" (183 cm) | 178–203 lbs | 160–192 lbs | 137–184 lbs |
| 6'2" (188 cm) | 190–215 lbs | 170–204 lbs | 145–195 lbs |
The Devine formula estimates ideal body weight from height and sex.
Devine: 50 kg + 2.3 kg per inch over 5 feet (10 inches over).
Result: 50 + 2.3×10 = 73 kg ≈ 161 lb.
Devine: 45.5 kg + 2.3 kg per inch over 5 feet (4 inches over).
Result: 45.5 + 2.3×4 = 54.7 kg ≈ 121 lb.
Ideal-weight formulas give a single number; a BMI-based healthy range is often more realistic.
Result: For 5'10", a BMI 18.5–24.9 range is ≈ 129–174 lb.
Formulas like Devine use your height and sex. They give a single reference number; a healthy BMI range (18.5–24.9) often gives a more realistic target band.
Not exactly. Ideal-weight formulas ignore muscle, frame size and body composition. Use them as a rough anchor, not a strict goal.
Formulas use a higher base for men, reflecting greater average muscle mass and bone density at the same height.
No — muscular athletes often exceed ‘ideal’ weight while being very lean. Body-fat percentage is a far better measure for them.
