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.
