Estimated ideal weight (Devine formula)
This is a general estimate based on height and sex only. It doesn’t account for muscle mass, frame size, or body composition. Not a substitute for medical advice.
4. Which Formula We Use, and Why
This calculator uses the Devine formula, originally developed for clinical use and still one of the most widely referenced methods for estimating ideal body weight today. Unlike some older calculators still using outdated formulas from the 1970s, the Devine formula remains a standard reference point in medical and fitness settings because of how consistently it performs across different body types.
We also cross-check your result against the healthy BMI range for your height, so you get a range, not just a single rigid number. Nobody has one “correct” weight — this gives you a realistic target zone instead.

| Height | Ideal Weight Range (Female) | Ideal Weight Range (Male) |

| 5’0″ (152 cm) | 45–50 kg (99–110 lb) | 50–54 kg (110–119 lb) |
| 5’2″ (157 cm) | 48–54 kg (106–119 lb) | 52–57 kg (115–126 lb) |
| 5’4″ (163 cm) | 52–58 kg (115–128 lb) | 56–61 kg (123–134 lb) |
| 5’6″ (168 cm) | 55–62 kg (121–137 lb) | 59–65 kg (130–143 lb) |
| 5’8″ (173 cm) | 59–66 kg (130–146 lb) | 63–68 kg (139–150 lb) |
| 5’10” (178 cm) | 62–70 kg (137–154 lb) | 66–72 kg (146–159 lb) |
| 6’0″ (183 cm) | — | 70–76 kg (154–168 lb) |

6. Frequently Asked Questions
How is ideal weight calculated? This calculator uses the Devine formula, which starts from a base weight for 5 feet of height and adds a fixed amount for every inch above that, adjusted by sex. It’s a widely used clinical reference point, cross-checked here against the healthy BMI range for your height.
What is the ideal weight calculator for women? For women, the Devine formula starts at 45.5 kg for 5 feet of height and adds 2.3 kg for every inch above that. Combined with the BMI healthy range for your height, this gives a realistic target zone rather than one fixed number — useful since ideal weight varies naturally by frame and muscle mass.
How do I calculate my ideal body weight by height and age? Height is the primary factor in ideal weight formulas like Devine — age isn’t a direct input, but body composition naturally shifts with age, so the same “ideal weight” number can feel different to hit at 25 versus 45. Use your calculated range as a target, and combine it with strength training to maintain a healthy body composition as you age.
How much should I weigh for my height? Enter your height into the calculator above for an instant estimate. As a rough guide, most healthy weight ranges fall within the BMI 18.5–24.9 zone for your height — the calculator shows you the exact kg or lb range for your specific height.
Is the ideal weight calculator accurate in kg? Yes — switch to the Metric tab above to get your result directly in kilograms. The Devine formula works in either unit system; the calculator handles the conversion for you.
Does ideal weight change with muscle mass? Yes. Formulas like Devine are based on height and sex only, so they don’t account for muscle mass. A muscular person may weigh more than their “ideal weight” while still being at a healthy body fat percentage. Use this tool as a general reference point, not an exact target.
Is this the same as my BMI healthy weight range? They’re related but not identical — BMI ranges are based purely on height, while the Devine formula was developed specifically to estimate ideal body weight in clinical settings. We show you both together here so you can compare.
