What Is a Healthy Weight for Your Height?

A healthy weight for your height is the range where your Body Mass Index (BMI) falls between 18.5 and 24.9. BMI is calculated as weight (kg) ÷ height (m)², or in pounds and inches: (weight ÷ height²) × 703. For a 5'6" (168 cm) adult, that range works out to roughly 115–154 lbs (52–70 kg).

That single number, 18.5 to 24.9, is the medical screening range used by the CDC, NIH, and WHO to flag whether a person's weight is likely to be putting them at higher risk for weight-related health conditions. It's not a diagnosis and it's not a verdict on how you look, it's a starting point, and the chart below turns that formula into real numbers for your actual height.

How BMI Determines a Healthy Weight

BMI works because it standardizes weight against height, so a 5'2" person and a 6'4" person aren't judged on the same raw pound count. The formula is simple on purpose:

BMI Formula: Weight (kg) ÷ [Height (m)]²  |  Imperial: [Weight (lbs) ÷ Height (in)²] × 703

Once you have the number, it's sorted into one of four standard categories used by nearly every major health authority worldwide. Your BMI Calculator does this math instantly, but knowing the ranges yourself makes the chart in the next section far more useful.

Healthy Weight for Women vs. Men

The BMI formula and the 18.5–24.9 healthy range apply identically to adult men and women, there's no separate formula for each sex. What differs is body composition: at the same BMI, women naturally carry a higher percentage of body fat than men, since essential fat levels differ biologically between the sexes.

Women
Typical healthy body fat: 21–33%
  • Same BMI formula and healthy range (18.5–24.9) as men
  • Naturally higher essential fat percentage at any given BMI
  • Hormonal factors (pregnancy, menopause) can shift healthy targets over time
Men
Typical healthy body fat: 8–19%
  • Same BMI formula and healthy range (18.5–24.9) as women
  • Tend to carry more muscle mass at the same height, which can push BMI slightly higher without added fat
  • Waist circumference is a useful secondary check for abdominal health risk

This is exactly why BMI is described as a screening tool, not a diagnostic one, it flags a range worth paying attention to, but body composition, muscle mass, and other factors give the fuller picture.

Limitations of BMI as a Measure

Every major health authority that publishes BMI ranges, including the CDC and NHS, also publishes the same caveat: BMI does not measure body fat directly, and it can misclassify healthy people in specific cases.

Where BMI gets it wrong: Muscular individuals and athletes often score as "overweight" despite low body fat, since BMI can't distinguish muscle mass from fat mass. Older adults can score as "normal" while carrying unhealthy fat levels, since muscle naturally declines with age even as weight stays stable. Pregnant women, and people with unusually tall or short stature, also fall outside what standard BMI ranges were designed to reflect.

None of this means BMI is useless, it's accurate for the large majority of adults and remains the standard first-pass screening metric worldwide precisely because it's fast, free, and requires no special equipment. It just means your BMI number is a starting point for a conversation, not the final word.

Other Ways to Check a Healthy Weight

If your BMI result feels off, given more muscle mass, an unusual frame size, or any of the exceptions above, these two supplementary checks add context:

For most people checking their weight against a simple, evidence-based standard, BMI combined with the chart above is enough. These extra checks matter most if your BMI result seems inconsistent with how you actually look and feel.

How to Use This Chart With Your BMI Result

Finding your row on the chart is only step one. The number you land on is a range, not a single target, and how you use it depends on where in that range you currently sit and what you're trying to do about it.

If your current weight already falls inside the healthy range for your height, the goal isn't to chase the exact midpoint, it's to maintain, since bodies naturally fluctuate a few pounds week to week without any real change in health. If you're above the range, the chart tells you roughly how much room exists between where you are and the top of your healthy band, which is a far more useful number than an arbitrary goal weight pulled from social media or a diet plan. If you're below the range, the same logic applies in reverse, the gap to the bottom of your healthy band is your realistic target, not a number chosen at random.

Practical tip: Use the midpoint of your healthy range as a general target rather than the extremes, it gives you buffer room on both sides and accounts for normal day-to-day weight fluctuation from water retention, food volume, and hormonal cycles.

It's also worth checking your number more than once. A single BMI reading taken after a heavy meal or an intense workout can shift slightly, so if you're tracking progress over time, weigh yourself under similar conditions, same time of day, similar clothing, and look at the trend across a few weeks rather than reacting to any single number.

Frequently Asked Questions

What is my BMI for my height and weight?
Your BMI is calculated by dividing your weight in kilograms by your height in meters squared (kg/m²), or in imperial units, your weight in pounds divided by your height in inches squared, multiplied by 703. A BMI between 18.5 and 24.9 is considered a healthy range for most adults.
What is the ideal body weight for my height?
Ideal body weight is typically estimated using formulas like the Devine or Hamwi formula, which factor in height and sex, or by finding the midpoint of the healthy BMI range (18.5-24.9) for your height. Both approaches give a target range rather than a single perfect number, since healthy weight also depends on muscle mass, frame size, and age.
What is the average weight for my height?
Average weight varies by country, age, and sex, and average weight is not the same as healthy weight, since population averages have shifted upward over recent decades. The healthy weight chart in this guide reflects medically recommended BMI-based ranges rather than population averages.
Is BMI different for men and women?
The BMI formula and healthy range (18.5-24.9) are the same for adult men and women, but body composition differs, women naturally carry a higher percentage of body fat than men at the same BMI, which is one reason BMI is a screening tool rather than a diagnostic one.
Can I be a healthy weight with a BMI outside the normal range?
Yes. BMI does not distinguish between muscle and fat, so athletes and highly muscular individuals often show as 'overweight' by BMI despite low body fat. Waist-to-height ratio and body-fat percentage are better indicators in these cases.
