Calculate Your Correct Weight Range
Enter your details below to estimate a healthy weight range and a practical target weight based on common adult formulas.
What is a "correct weight"?
A correct weight is not one perfect number. For most adults, it is a healthy range that supports energy, mobility, good blood markers, and long-term wellbeing. This calculator combines a BMI-based healthy range with classic ideal-weight formulas to give you a practical target.
Think of this as a planning tool, not a diagnosis. Body composition, genetics, muscle mass, age, and health conditions all matter.
How this calculator works
1) Healthy BMI range
First, it estimates your healthy weight interval using the standard adult BMI range of 18.5 to 24.9. This gives a broad "safe zone" based on your height.
2) Formula-based estimate
Then it calculates ideal weight using three well-known methods (Devine, Robinson, and Hamwi) and averages them. This gives a center point that many people find practical for goal setting.
3) Practical target zone
Finally, it creates a narrower target zone around the formula average while staying inside the healthy BMI range. This can make your goal feel more realistic and measurable.
Why a range is better than a single number
- Body water and glycogen can shift scale weight day-to-day.
- Two people at the same weight may have very different muscle-to-fat ratios.
- Frame size and bone structure influence comfortable body weight.
- Health outcomes usually improve across a range, not at one exact value.
How to use your result
If you are above your target zone
Focus on steady progress: small calorie deficits, high-protein meals, regular strength training, and consistent sleep. A sustainable pace is usually better than aggressive short-term dieting.
If you are below your target zone
Increase calories gradually with nutrient-dense meals, resistance exercise, and enough recovery. Aim to gain slowly, with strength and energy as key indicators of progress.
If you are inside your target zone
Shift to maintenance habits: stable meal timing, weekly movement goals, and monthly check-ins. Your objective becomes stability, not constant weight change.
Healthy weight habits that actually last
- Protein first: include protein in each meal to support satiety and muscle.
- Daily movement: combine walking, strength work, and mobility.
- Sleep consistency: poor sleep can increase hunger and reduce recovery.
- Hydration: mild dehydration can feel like fatigue or hunger.
- Track trends: monitor weekly averages, not single weigh-ins.
Important note
This calculator is intended for general adult education. It is not a substitute for medical advice. If you are pregnant, under 18, managing a chronic condition, or recovering from an eating disorder, speak with a qualified clinician before using weight targets.
Bottom line
Your correct weight is best viewed as a healthy operating range. Use this tool to set direction, then personalize your approach based on strength, energy, bloodwork, and how you feel day to day.
