Ever stood on a scale at the doctor's office, looked at the number, and then immediately looked at the wall chart to see where you "fit"? If you’re a guy standing 5 feet 9 inches tall, you’re basically the "everyman." You are the exact height used by the CDC as the national average for adult males in the United States. But here’s the kicker: being the average height doesn't mean the average weight for a man 5 9 is actually healthy.
Actually, it's kinda the opposite.
According to the most recent data from the National Center for Health Statistics (NCHS), the average weight for a man 5 9 in the U.S. is approximately 197.9 to 199 pounds.
That’s a big number.

If you do the math, a 199-pound man at 5'9" has a Body Mass Index (BMI) of roughly 29.4. On the official charts, that’s just a hair’s breadth away from being classified as "obese" (which starts at 30.0). So, while 199 pounds is the average—meaning what most guys actually weigh—it is definitely not the ideal weight by medical standards.
The Gap Between Average and Ideal
We have to distinguish between what people actually weigh and what doctors want them to weigh. It’s a massive gap. Most health organizations, including the American Heart Association and the CDC, suggest that a "healthy" weight for someone 5'9" falls between 128 and 162 pounds.
Wait.
128 pounds? Honestly, most guys at 5'9" would look like they’ve skipped a few months of meals at 128. That's the very bottom of the "normal" range. On the flip side, the 162-pound upper limit feels more realistic for someone with an average build, but even then, many athletic men carry more muscle than that.
Breaking Down the BMI Categories for 5'9"
- Underweight: Anything under 125 lbs.
- Healthy Weight: 128 to 162 lbs.
- Overweight: 169 to 202 lbs.
- Obese: 203 lbs and up.
See the problem? The "average" American man (at 199 lbs) is technically right at the top of the "Overweight" category. We've normalized being heavier.
Why the Number on the Scale Lies
Let's talk about the "meathead" factor.
BMI is a pretty blunt tool. It doesn't know the difference between five pounds of beer-belly fat and five pounds of bicep muscle. If you’re a guy who hits the gym four days a week and has a decent amount of muscle mass, you might weigh 190 pounds and look "fit," yet your doctor's chart will scream that you're overweight.
Muscle is dense. It takes up less space than fat.
That’s why many experts, like those at Rush University System for Health, suggest looking at waist circumference alongside weight. For a man, a waist measurement of over 40 inches is a much bigger red flag for heart disease and Type 2 diabetes than just having a high BMI. If you're 195 pounds but your waist is 32 inches, you’re probably in better shape than a "skinny-fat" guy who weighs 160 but has a 36-inch gut.
The Body Fat Percentage Reality
If you really want to know how you’re doing, look at body fat.

- Athletic: 6% to 13%
- Fitness: 14% to 17%
- Acceptable: 18% to 25%
- Obese: 26% or higher
For a 5'9" man, staying in that 15% to 20% range is usually the "sweet spot" where you look healthy and your blood markers (cholesterol, blood sugar) stay in the green.
Age Changes the Equation
You aren't the same person at 50 as you were at 20. Biology is a bit of a jerk like that. As we age, we naturally lose muscle mass—a process called sarcopenia—and our metabolism slows down.
A study published in The Lancet and various NHANES reports suggest that carrying a little extra weight might actually be protective as you get into your 70s. It’s called the "obesity paradox." While being 200 pounds at 5'9" might be hard on a 25-year-old’s heart, a 75-year-old with that same weight might have better "reserve" to fight off infections or recover from surgery.
But for most of us in the 30-to-60 bracket? That extra weight is usually just putting strain on the knees and the cardiovascular system.
Risks of Staying at the "Average" Weight
Since the average weight for a man 5 9 is currently about 199 pounds, many men feel a false sense of security. "I'm just like everyone else," they think. But being average in a country with high rates of metabolic syndrome isn't a great goal.
Research from MedlinePlus and the WHO links a BMI over 25 (which starts at 169 lbs for this height) to:
- High Blood Pressure: Your heart has to pump harder to move blood through more tissue.
- Sleep Apnea: Fat deposits around the neck can literally block your airway at night.
- Joint Pain: Every extra pound puts about 4 pounds of pressure on your knee joints when you walk.
- Insulin Resistance: This is the precursor to Type 2 diabetes.
Actionable Steps: What Should You Do?
Stop obsessing over hitting 150 pounds if you have a large frame. It might not be realistic. Instead, focus on these three metrics that actually correlate with living longer:
- Check your waist-to-height ratio: Your waist circumference should be less than half your height. For a 5'9" man (69 inches), your waist should ideally be 34.5 inches or less.
- Prioritize Lean Mass: Instead of just "losing weight," focus on "recomposition." Lift weights. Eat protein. If you stay 190 pounds but drop two pant sizes, you’ve won.
- Watch the visceral fat: This is the "hard" belly fat that sits around your organs. It’s metabolically active and dangerous. High-intensity intervals and cutting back on processed sugars are the fastest ways to target it.
Ultimately, the average weight for a man 5 9 is just a statistic. It tells us where the population is, not where you specifically should be. If you’re feeling sluggish or your joints ache, don't look at the average; look at your own body composition and start moving the needle toward that 165-175 pound range, provided you're keeping your muscle intact.
Focus on how your clothes fit and how your energy levels feel during the day. Those are much better indicators of health than a generic number on a scale.
