How Much Should A 5’8 Man Weigh? | Healthy Range By Age

Plenty of men around 5 feet 8 inches step on the scale and wonder, almost word for word, “how much should a 5’8 man weigh?” The worry usually isn’t about a single number, but about health, energy, and how clothes fit.

There isn’t one magic target for every 5’8 guy. Instead, there’s a healthy range shaped by body fat, muscle mass, age, and waist size. This article gives you clear numbers, shows where those numbers come from, and offers simple checks you can use before you talk with your own doctor about personal goals.

How Much Should A 5’8 Man Weigh? In Simple Numbers

Health agencies use body mass index (BMI) as a basic screening tool for adults. A “healthy weight” BMI for men is usually set between 18.5 and 24.9. For a height of 5’8 (68 inches), that BMI range lines up with roughly 122 to 164 pounds.

In day-to-day life, many active 5’8 men carry more muscle than average. That can push a healthy, fit man into the 140 to 170 pound window without raising health risk. So when you ask, “how much should a 5’8 man weigh?”, a fair reply is a range, not one exact figure.

To see how this plays out, it helps to line up BMI categories with weight bands for 5’8 men.

BMI Category	BMI Range	Approximate Weight Range At 5’8 (lb)
Underweight	Below 18.5	Below 122
Healthy Weight (Lower End)	18.5–21.9	122–144
Healthy Weight (Upper End)	22.0–24.9	145–164
Overweight	25.0–29.9	165–196
Obesity Class I	30.0–34.9	197–229
Obesity Class II	35.0–39.9	230–262
Obesity Class III	40.0 And Above	263 And Above

These bands come from the standard BMI formula, which uses height and weight to place adults into underweight, healthy weight, overweight, and obesity groups. They work well as a first pass, yet they miss key details such as where you carry fat and how much muscle you have.

Healthy Weight Range For A 5’8 Male By Age

Two men can both stand 5’8 and weigh 165 pounds, yet feel very different in their bodies. Age is a big reason. Muscle usually peaks in the twenties and thirties, then slowly drops if strength training and protein intake slip.

That means a 165-pound 25-year-old who lifts and runs may carry far more muscle than a 165-pound 55-year-old who sits all day. Their BMI would match, but their health risk, waist size, and stamina could be quite different.

You can see how health agencies group BMI into risk categories on the official CDC adult BMI categories page. The cut-offs stay the same across adult ages, yet doctors often pay closer attention to blood pressure, blood sugar, and waist size as men move into their forties and beyond.

Younger Adult Men (Around 18–35)

For many younger 5’8 men, a healthy spot often falls in the 140 to 170 pound range. In this stage, higher muscle mass is common, and it can nudge BMI toward the high end of “healthy” or even slightly into the “overweight” band without clear health problems.

Red flags at this age usually show up more through habits and waist size than through a single scale reading. A 5’8 man at 165 pounds with a 33-inch waist, good fitness, and steady energy is in a very different place from a 5’8 man at the same weight with a 40-inch waist who gets breathless on a short flight of stairs.

Middle Aged Men (Around 36–55)

Hormone changes, long work days, and less movement can nudge weight upward through these years. For a 5’8 man, staying in roughly the 145 to 175 pound window while keeping waist size under about 40 inches tends to line up with lower risk in large studies.

If weight creeps toward the 180s and 190s and waist size grows past 40 inches, health risk climbs faster, even if BMI still sits in the “overweight” band. That is why many doctors track both BMI and waist circumference at this stage.

Older Men (Around 56 And Above)

From the late fifties onward, bone density and muscle mass often drop. Some men lose weight yet see their waist stay large. Others gain fat even though their clothes feel similar in the shoulders and chest.

For a 5’8 man in this age range, a scale reading near the middle or lower end of the “healthy” BMI band (roughly 135 to 160 pounds) can pair well with good strength, balance work, and a waist below about half of height. That means aiming for a waist under roughly 34 inches when possible.

How To Check Your Own Healthy Weight At 5’8

Instead of chasing one perfect number, you can build a small set of checks that give a fuller picture. Here is a simple way to do that if you stand 5’8.

Step 1: Measure Height Correctly

Stand barefoot with your heels, back, and head against a wall. Ask someone to rest a flat object, like a book, on top of your head and mark the wall. Measure from floor to mark. Many men who report 5’10 in casual talk turn out to be closer to 5’8 once measured this way.

Your real height matters for BMI math. A difference of even one inch will change the range that looks healthy on paper.

Step 2: Weigh Yourself Consistently

Use the same scale, on a hard floor, with bare feet. Weigh yourself at the same time of day, ideally in the morning after using the bathroom and before breakfast.

Day-to-day swings of one or two pounds come from water and food. Watch the trend over a few weeks instead of reacting to each single reading.

Step 3: Calculate Bmi For A 5’8 Man

BMI uses this formula with pounds and inches:

BMI = (Weight In Pounds × 703) ÷ (Height In Inches)²

For a 5’8 man at 160 pounds, that comes out roughly like this: (160 × 703) ÷ (68 × 68) ≈ 24.3, which sits inside the healthy range. You can also plug your numbers into the NHLBI BMI calculator if you prefer not to do the math by hand.

If your number lands between 18.5 and 24.9, your weight for 5’8 fits the standard “healthy weight” band. Numbers from 25 to 29.9 fall into “overweight”, and 30 or above pick up obesity labels.

Step 4: Measure Waist And Look At Body Fat

Wrap a tape around your bare midsection, just above the hip bones. Breathe out gently and read the number. Research shows that a waist bigger than about 40 inches in men links to higher risk for heart disease and type 2 diabetes, even when BMI is not very high.

If you can, add a body fat estimate from a smart scale, gym assessment, or clinic. For many 5’8 men, body fat around 12–20 percent tends to look lean and feel strong, while 21–24 percent feels average, and 25 percent or more often lines up with more belly fat.

Factors That Change A Healthy Weight Range

Two 5’8 men can share the same BMI and waist size, yet their health pictures can still differ. A few background factors shift how much weight a 5’8 man can carry comfortably.

Muscle Mass And Training History

A long-time lifter or manual worker at 5’8 may sit at 180 pounds with solid legs, a firm back, and a modest waist. On paper his BMI lands in the “overweight” range, yet his risk markers can look better than those of a slimmer but inactive man.

By contrast, someone who rarely moves and eats a lot of calorie-dense food might reach 180 pounds at 5’8 with far less muscle and more belly fat. That pattern usually carries more health risk than the same weight on a muscular frame.

Frame Size And Bone Structure

Some men have naturally narrow wrists, ankles, and shoulders. Others have thicker bones and broader joints. A broader frame can carry a little more weight with the same health markers.

If watches, rings, and sleeves tend to feel snug even when you are lean, you may fall into that broader-frame group. That can nudge your comfortable range a few pounds higher within the same BMI band.

Ethnic Background And Fat Distribution

Large studies show that some ethnic groups face higher health risks at lower BMI values. In many South and East Asian groups, for instance, risk for diabetes and heart disease climbs sooner, especially when fat gathers around the waist.

That means two 5’8 men at 155 pounds may not share the same risk. One may already need closer lab checks and lifestyle changes even though BMI looks fine on a basic chart.

Existing Health Conditions And Medications

Conditions like type 2 diabetes, sleep apnea, or joint pain change how much extra weight the body can handle. Several common medications also raise appetite or slow metabolism, which can push a 5’8 man above his earlier stable range.

If your weight changed soon after a new diagnosis or new prescription, that context matters more than any single “ideal” number from a chart.

Sample Targets For Different Goals At 5’8

To make all these numbers more practical, here is a second table with rough target ranges for 5’8 men in common situations. These are not strict rules, but they can help you decide whether you want to hold, gain, or lose.

Goal Or Build	Approximate Weight Range (lb)	Typical Body Fat Range (%)
Lean, Desk Job, Light Exercise	140–155	15–22
Active Lifestyle, Mixed Cardio And Weights	150–170	12–20
Strength Training Focus, Higher Muscle Mass	165–185	12–18
Endurance Sports Focus (Running, Cycling)	140–160	10–18
Early Fat Loss Phase From Obesity Range	180–210	25–35
Older Adult, Moderate Activity	135–160	18–26
Health Recovery After Illness Or Injury	Based On Medical Advice	Body Fat Target Set Clinically

Again, each row is only a starting point. A 5’8 man lifting heavy four days a week might feel his best at 180 pounds with body fat near 15 percent, while another feels best at 155 pounds with more focus on running.

What matters most is how your weight lines up with lab results, blood pressure, waist size, sleep quality, mood, and day-to-day energy, not just how it looks in a chart or table.

Using The Answer Without Obsessing Over One Number

By now, you have a clear picture of how much a 5’8 man should weigh in broad terms. Healthy bands tend to sit between about 140 and 170 pounds for most men at this height, with lower and higher values sometimes fitting, depending on muscle, waist size, and health history.

So when the question “how much should a 5’8 man weigh?” pops into your head the next time you step on the scale, you can answer yourself with more nuance. Check your BMI, measure your waist, look at your habits, and ask how you feel walking, climbing stairs, playing with kids, or training.

If your numbers worry you, or if you have medical conditions that change your risk, bring your readings to your doctor or a registered dietitian. They can help you pick a personal target weight and waist size that suits your body, your health, and your daily life, then build a plan that gets you there at a steady, sustainable pace.
