Let’s be real. If you’re a guy standing 5'6, checking your "ideal" weight can be a total head-trip. You pull up a chart, see a number, and immediately think, "Wait, if I hit that, I'll look like a stick." Or maybe the opposite happens. You feel solid, you're lifting heavy, but the doctor’s office scale says you’re borderline obese. It’s frustrating.
The truth about the average weight male 5'6 is way more nuanced than a single number on a digital display. We’re talking about a height that sits right in that middle ground where five pounds of muscle or five pounds of fat completely changes your silhouette.
What the Data Actually Says
According to the Centers for Disease Control and Prevention (CDC), the average weight for an adult man in the United States has been hovering around 197 pounds for a few years now. But here’s the kicker: that average doesn't account for height. For a man who is 5'6, 197 pounds would put his Body Mass Index (BMI) at roughly 31.8. In clinical terms? That’s Class I Obesity.
Statistics from the National Health and Nutrition Examination Survey (NHANES) suggest that the actual median weight for a 5'6 male is often lower than the national average, yet still higher than what "medical ideals" suggest. Most men at this height tend to fall between 165 and 185 pounds.
Is that healthy? It depends.
If you look at the Metropolitan Life Insurance Company’s historical height and weight tables—which, honestly, many old-school trainers still swear by—a man with a "medium frame" at 5'6 should weigh between 142 and 154 pounds. If you have a "large frame," they bump that up to 149–168 pounds.
But those tables are decades old. They don't account for the fact that we’re generally more muscular (or at least heavier) than people were in the 1950s.
The BMI Problem for the 5'6 Frame
BMI is a simple math equation: weight in kilograms divided by height in meters squared. For a 5'6 male, the "Normal" range is roughly 115 to 154 pounds.

That’s a massive range.
Honestly, 115 pounds on a 5'6 man is incredibly lean. Think marathon runner or someone with a very slight build. On the flip side, 154 pounds can look vastly different depending on whether that weight is stored in the belly or the shoulders.
The biggest flaw with BMI for men of this height is that it ignores body composition. If you spend any time at the gym, you know that muscle is much denser than fat. A 5'6 bodybuilder might weigh 180 pounds with 10% body fat. According to the chart, he’s "Obese." In reality? He’s probably the healthiest person in the room.
Frame Size Matters More Than You Think
You’ve probably heard people say they are "big-boned." It sounds like an excuse, but there’s actual science behind it. Clinicians often use the wrist-to-height ratio to determine frame size.
Try this: wrap your thumb and middle finger around your opposite wrist.
- Do they overlap? You likely have a small frame.
- Do they just touch? You’re medium.
- Is there a gap? You’ve got a large frame.
For an average weight male 5'6, a large frame can easily carry 15 to 20 pounds more than a small-framed guy while maintaining the same body fat percentage. This is why comparing yourself to a friend the same height is usually a waste of time. Your skeletons literally weigh different amounts.

The Role of Age and Metabolism
The weight you carried at 22 is rarely the weight you carry at 45. As men age, testosterone levels naturally dip—usually by about 1% to 2% every year after age 30. This shift makes it easier to gain visceral fat (the stuff around the organs) and harder to keep muscle mass.
A 5'6 man in his 50s might find his "comfortable" weight is around 170 pounds. While a doctor might want that lower, the "Obesity Paradox" suggests that in older age, carrying a few extra pounds might actually provide a buffer against certain chronic illnesses, provided it isn't excessive.
Waist Circumference: The Metric That Actually Matters
If you want to move past the average weight male 5'6 obsession, grab a tape measure. Experts like those at the Mayo Clinic argue that waist circumference is a much better predictor of health than the scale.
For a man, a waist measurement over 40 inches is a red flag. It points to high levels of abdominal fat, which is linked to Type 2 diabetes and heart disease. If you're 5'6 and weigh 175 pounds but your waist is 32 inches, you're likely in great shape. If you weigh 150 pounds but your waist is 38 inches (the "skinny-fat" phenomenon), you might actually be at higher health risk than the heavier guy.
Real-World Examples of the 5'6 Build
Look at professional athletes. Dustin Poirier, the famous UFC fighter, is roughly 5'9, but many fighters in the Featherweight division (145 lbs) or Lightweight division (155 lbs) stand around 5'6 or 5'7. These men are at the peak of human performance. However, they "walk around" much heavier than their fight weight, often hitting 170+ pounds in the off-season.
Then you have guys like professional gymnasts. They are often around this height and carry significant muscle mass, frequently weighing in the 150s or 160s. They don't look "average." They look powerful.
The point is, the number is just data. It isn't destiny.
Actionable Steps for Finding Your Best Weight
Instead of chasing a generic "average," focus on these specific markers to find where your body functions best.
1. Calculate your Waist-to-Height Ratio.
Keep your waist circumference to less than half your height. If you are 5'6 (66 inches), aim for a waist that is 33 inches or less. This is a much more accurate health marker than BMI.
2. Prioritize Protein and Resistance Training.
Since the 5'6 frame can look "stocky" easily, building muscle in the upper back and shoulders (the V-taper) creates a more athletic aesthetic regardless of what the scale says. Aim for 0.8 grams of protein per pound of body weight.
3. Get a DEXA Scan or Hydrostatic Weighing.
If you're serious about your health and the BMI is stressing you out, get a real body composition test. These scans tell you exactly how much of your weight is bone, muscle, and fat. Knowing you have a high bone density can explain why you're "heavy" for your height.

4. Watch the Visceral Fat.
If your weight gain is strictly in the midsection, it's time to adjust. Focus on walking 8,000–10,000 steps a day. It’s boring advice, but for the average weight male 5'6, consistent low-intensity movement is the most sustainable way to keep the "gut" at bay without crashing your metabolism.
5. Adjust Based on Energy, Not Just Aesthetics.
Ask yourself: How is my sleep? How is my libido? Am I crashing at 3 PM? Often, trying to force your body down to a "theoretical" ideal weight of 140 pounds will leave you feeling exhausted and irritable. Sometimes, your body's "set point" might be 160 pounds, and you'll feel significantly better staying there.
Stop looking at the global average and start looking at your own biometrics. A 5'6 man who is 170 pounds with a 32-inch waist is doing significantly better than a 145-pound man with no muscle tone and high cholesterol. The scale is a tool, not a judge. Focus on how you move and how your clothes fit, and the "average" will take care of itself.
