How Much Should I Weigh for My Height and Age?

A healthy weight for your height generally falls within a body mass index (BMI) of 18.5 to 24.9, which translates to a wide range of actual pounds depending on how tall you are. A 5’4″ person, for example, falls in the healthy range between about 108 and 145 pounds, while someone who is 5’10” lands there between roughly 129 and 174 pounds. But that single number on the scale doesn’t tell the whole story, and the “right” weight for you depends on your age, body composition, and where your body carries fat.

Healthy Weight Ranges by Height

BMI is calculated by dividing your weight in kilograms by your height in meters squared. The CDC defines the categories for adults 20 and older like this:

  • Underweight: BMI below 18.5
  • Healthy weight: BMI 18.5 to 24.9
  • Overweight: BMI 25 to 29.9
  • Obesity (Class 1): BMI 30 to 34.9
  • Obesity (Class 2): BMI 35 to 39.9
  • Severe obesity (Class 3): BMI 40 or higher

To put that into practical numbers, here are healthy weight ranges (BMI 18.5 to 24.9) for common heights:

  • 5’0″: 95 to 127 lbs
  • 5’2″: 101 to 136 lbs
  • 5’4″: 108 to 145 lbs
  • 5’6″: 115 to 154 lbs
  • 5’8″: 122 to 164 lbs
  • 5’10”: 129 to 174 lbs
  • 6’0″: 137 to 184 lbs
  • 6’2″: 144 to 194 lbs
  • 6’4″: 152 to 205 lbs

Notice how wide these ranges are. Two people who are both 5’8″ could weigh 122 or 164 pounds and both fall in the healthy category. That’s because “healthy” isn’t one number. It’s a zone, and where you sit within it matters less than other indicators of metabolic health.

Why BMI Doesn’t Work for Everyone

BMI was designed as a population-level screening tool, not a personal health verdict. It treats all weight the same, whether that weight comes from muscle, bone, or fat. A study of 172 collegiate athletes illustrates the problem clearly: BMI classified about 36% of them as overweight and 4% as obese, but when researchers measured their actual body fat, 89% had healthy fat levels. BMI and body fat percentage only agreed 59% of the time. The mismatches almost always went one direction: BMI called athletes overweight when their body fat was perfectly normal.

This doesn’t just apply to elite athletes. Anyone who carries above-average muscle mass, whether from regular strength training, physical labor, or naturally heavier bone structure, can register as overweight by BMI while being metabolically healthy. On the flip side, someone with a “normal” BMI but very little muscle and a high proportion of body fat may face real health risks that BMI completely misses.

Your Ethnicity Changes the Thresholds

Standard BMI cutoffs were developed from studies of primarily white European populations, and they don’t translate evenly across ethnic groups. South Asian populations, for instance, develop metabolic problems like type 2 diabetes at significantly lower weights. A meta-analysis published in Circulation found that the BMI associated with diabetes risk equivalent to a BMI of 30 in white populations was just 23.3 in South Asians. That’s a difference of nearly 7 BMI points, moving the risk threshold from what’s normally considered obese all the way down to what’s considered a normal weight.

For South Asian men, the optimal cutoff for high blood pressure risk was also 23.3, and for South Asian women it was 24.0. If you’re of South Asian, East Asian, or Southeast Asian descent, the standard “healthy weight” range likely overestimates what’s safe for you. A BMI in the low 20s, rather than the mid-20s, is a more appropriate target.

Healthy Weight Shifts as You Age

If you’re over 65, the standard BMI categories may actually underestimate your ideal weight. The National Institutes of Health suggests that a BMI of 25 to 27, which would be classified as overweight for younger adults, may be the sweet spot for older adults. That modest extra weight appears to protect against osteoporosis and provides reserves that help with recovery from illness or surgery.

At the same time, a BMI below 23 starts to carry higher risk in older adults, as does a BMI above 33. The lowest-risk zone for people over 65 is notably higher than the 18.5 to 24.9 range used for younger adults. For a 5’6″ person over 65, that translates to roughly 155 to 167 pounds, compared to a standard healthy range that tops out at 154.

Better Ways to Check Your Health Than Weight Alone

Waist-to-Height Ratio

Where your body stores fat matters more than how much you weigh overall. Fat that accumulates around your midsection, known as visceral fat, wraps around your organs and drives up risk for heart disease, diabetes, and stroke. Fat stored in your hips and thighs is far less dangerous.

Your waist-to-height ratio captures this distinction in a way BMI cannot. Measure your waist at belly-button level, then divide that number by your height (both in inches or both in centimeters). A ratio above 0.5 signals elevated risk. Research from the University of Pittsburgh found that people with a BMI under 30 but a waist-to-height ratio over 0.5 still showed increased risk of coronary artery calcification, a key marker of heart disease. In other words, you can weigh a “normal” amount and still carry dangerous levels of abdominal fat.

For someone who is 5’6″ (66 inches), a waist measurement above 33 inches crosses that 0.5 threshold. This takes about 10 seconds to check at home with a tape measure, and it tells you something your bathroom scale never can.

Body Fat Percentage

Body fat percentage separates your weight into fat and everything else (muscle, bone, water, organs). A 2025 study using national survey data defined overweight as 25% body fat or higher for men and 36% or higher for women. Obesity thresholds were 30% for men and 42% for women. Body fat naturally increases with age, so percentages that are normal at 65 would be considered high at 25.

Getting an accurate body fat measurement typically requires a DEXA scan or hydrostatic weighing. Consumer-grade scales and handheld devices that estimate body fat use electrical impedance and can vary widely depending on hydration, time of day, and the device itself. They’re useful for tracking trends over time but shouldn’t be treated as precise.

Putting It All Together

Your ideal weight for your height isn’t a single number. It’s a range shaped by your age, ethnicity, muscle mass, and fat distribution. BMI gives you a reasonable starting point: for most adults under 65, aim for 18.5 to 24.9. If you’re over 65, a BMI of 25 to 27 may be more protective. If you’re of South Asian or East Asian descent, a BMI in the low 20s is a safer benchmark.

Beyond the scale, check your waist-to-height ratio. If it’s under 0.5, that’s a strong signal that your weight, whatever the number, isn’t putting your heart at excess risk. If it’s above 0.5, losing even a small amount of abdominal fat can meaningfully improve your metabolic health, regardless of what BMI says.
