Ideal Weight Calculator
Find the healthy weight range for your height.
About the Ideal Weight Calculator
The ideal weight calculator answers one of the most common health questions: what should I weigh for my height? Rather than a single magic number, it gives you the healthy weight range that corresponds to a BMI between 18.5 and 24.9 — the range associated with the lowest weight-related health risk for most adults.
The calculation works backward from BMI: it takes your height, converts it to metres, and computes the weight that would produce a BMI of 18.5 (the lower bound) and 24.9 (the upper bound). For a person 170 cm tall, the healthy range is roughly 53–72 kg. Anyone within that band is considered a healthy weight regardless of which specific figure they land on.
Frame size makes a genuine difference. A person with a large bone structure and substantial muscle mass will naturally sit at the upper end of the range or slightly beyond it, while a small-framed person may be healthy at the lower end. The range is a guide, not a verdict — two people of the same height and weight can have very different body compositions.
In Pakistan, where both underweight and obesity are health concerns — undernutrition affecting children and some adults, while urban obesity drives rising diabetes rates — knowing your healthy range helps set realistic goals. The range also provides a sensible target for gradual weight change: moving toward the middle of the range is a reasonable and achievable goal.
Use this calculator alongside the BMI and BMR tools on this page for a complete picture: BMI tells you where you are now, the ideal range tells you where a healthy weight would be, and BMR helps you plan the calorie intake to get there sustainably.
How to find your healthy weight range
- 1
Measure your height in centimetres.
- 2
Enter it in the calculator.
- 3
Read your healthy weight range — the weights corresponding to a BMI of 18.5 to 24.9 for your height.
- 4
Use the range as a target: if you are above it, aim for gradual weight loss toward the middle of the band.
Frequently Asked Questions
What weight is ideal for my height?
The healthy range is the weight that puts your BMI between 18.5 and 24.9. For 170 cm that is roughly 53–72 kg. Individual builds vary, so treat it as a guide.
What is the ideal weight for a 5'6" (168 cm) person?
For 168 cm, the healthy range is about 52–70 kg, corresponding to a BMI of 18.5–24.9. Your specific ideal depends on your frame size, muscle mass and build.
Is ideal weight the same for men and women?
The BMI-based healthy range is the same formula for both sexes, though women typically have a higher healthy body-fat percentage. Men often carry more muscle, so a man and woman of the same height may have different 'ideal' weights in practice.
What if I am above the healthy range?
Aim for gradual weight loss of about 0.5–1 kg per week through a modest calorie deficit and increased activity. Even moving partway into the healthy range substantially reduces health risk.
