Ideal Weight Calculator
Ideal weight is an estimated healthy weight range based on height and gender. It's a benchmark — not an exact goal. Calculate your range below and see what actually drives the results forward.

Ideal weight is a benchmark — not a calorie plan
Ideal weight tells you an end goal on the scale. It does not tell you how to get there, how fast it is reasonable, or what to eat to stay there. Those are three entirely different questions.
Most people who focus solely on a target weight miss the most important variable: their actual calorie needs (TDEE). Without tracking that against a correct target, the body does not move in the right direction — regardless of how accurate the ideal weight is.
What ideal weight does not account for
- Muscle mass — a well-trained person can weigh 5–10 kg more than the ideal weight formula and have excellent health
- Body fat percentage — the same weight can mean 15% or 30% body fat depending on training level
- Activity level — calorie needs vary greatly with exercise, and the formula does not adjust for it
- Metabolism — adaptive thermogenesis during prolonged calorie restriction means a static ideal weight figure does not help you plan a realistic timeline
How to actually reach your target weight
- Calculate your TDEE (total daily calorie needs)
- Set a calorie target with a moderate deficit — 300–500 kcal/day
- Eat 1.6–2.2 g protein per kg body weight to protect muscle mass
- Adjust your calorie target every 2–3 weeks based on actual weight trend
Frequently Asked Questions
What counts as ideal weight?
Ideal weight is an estimated weight range based on your height and gender, often calculated via formulas like Robinson (1983) or BMI 18.5–24.9. It's a benchmark, not an exact goal. Factors like muscle mass, age, bone size and training level affect what is healthy for you specifically.
Is ideal weight the same as BMI?
No — but they are related. BMI (Body Mass Index) is a number calculated from weight and height. Ideal weight is a weight range corresponding to a healthy BMI (18.5–24.9). The difference is that ideal weight formulas like Robinson adjust for height and gender separately, while BMI is a pure ratio.
Can you weigh more and still be healthy?
Yes. Muscle weighs more than fat, and a well-trained person can weigh more than the ideal weight formula indicates without increased health risk. Body fat percentage, waist circumference and metabolic markers (blood pressure, blood fats) are better indicators of health risk than weight alone. Ideal weight is a benchmark — not an absolute limit.
How much should you lose per week?
0.3–0.7 kg per week is a healthy pace that minimizes muscle loss. It requires a calorie goal of about 300–700 kcal below your TDEE per day. Faster weight loss increases the risk of losing muscle mass and negatively affecting your metabolism.
Is ideal weight relevant if you strength train?
Limited. People who strength train build muscle mass that increases weight without increasing fat mass. A well-trained person can weigh 5–10 kg more than the ideal weight formula indicates and have excellent health. For those who train regularly, TDEE calculation, macro planning and body fat percentage are more relevant measures than an ideal weight number.
From ideal weight to action plan
You know the target weight. The next step is to calculate your calorie goal and start logging against it.
