A healthy weight for a 5’11” male falls between 136 and 179 pounds, based on standard BMI guidelines. That’s a wide range, and where you land within it depends on your age, muscle mass, and how your body carries fat. The number on the scale matters less than most people think.
The Standard Weight Range for 5’11”
The National Heart, Lung, and Blood Institute breaks weight into categories for someone who is 5’11”:
- Healthy weight: 136 to 179 lbs (BMI 19 to 24)
- Overweight: 179 to 208 lbs (BMI 25 to 29)
- Obese: 215 to 257 lbs (BMI 30 to 35)
- Severely obese: 265 lbs and above (BMI 36+)
These numbers come from BMI, which divides your weight in kilograms by your height in meters squared. The CDC still uses BMI 25 as the overweight threshold and BMI 30 as the obesity threshold, with no changes to those cutoffs as of 2025.
What “Ideal Weight” Formulas Say
Doctors have used clinical formulas for decades to estimate a target weight. The Hamwi method, one of the most common, starts with 106 pounds for the first five feet of height and adds 6 pounds per inch after that. For a 5’11” man, that puts the ideal at about 172 pounds.
Other formulas (Devine, Robinson, Miller) each produce slightly different numbers, typically landing somewhere between 155 and 175 pounds. None of these were designed for precision. They were originally created to help calculate medication doses, not to define what your body should weigh. Think of them as rough midpoints, not goals.
Why BMI Misses the Full Picture
BMI treats all weight the same. It can’t tell the difference between 200 pounds of muscle and 200 pounds of fat on a 5’11” frame. A man who lifts weights regularly could easily weigh 195 pounds, land in the “overweight” BMI category, and be in excellent health. Body composition is a more reliable indicator of health than body weight or BMI alone, because not all weight is equal in terms of tissue type and distribution.
This matters practically. If you’re physically active and carry noticeable muscle mass, a BMI of 26 or 27 may be perfectly healthy for you. If you’re sedentary and carry most of your weight around your midsection, a BMI of 24 could still come with metabolic risks.
Waist Size as a Better Marker
One of the simplest ways to gauge whether your weight is in a healthy zone is your waist measurement. The NHS recommends keeping your waist circumference below half your height. For a 5’11” man (71 inches tall), that means a waist under 35.5 inches.
A waist-to-hip ratio above 0.90 in men indicates abdominal obesity, regardless of what the scale reads. This type of fat, called visceral fat, wraps around your internal organs and is strongly linked to type 2 diabetes, high cholesterol, and cardiovascular disease. You can be within a “normal” weight range and still carry dangerous amounts of visceral fat if most of it sits around your abdomen.
How Age Changes the Target
Your body composition shifts as you get older, even if your weight stays the same. Average body fat in men rises from about 23% in the late teens to roughly 31% by ages 60 to 79, based on national body scan data. That means a 60-year-old man at 175 pounds likely has significantly more fat and less muscle than a 25-year-old at the same weight.
The National Institute on Aging notes that healthy weight ranges for older adults differ from those for younger people. Online BMI calculators only tell part of the story. Older adults at a “normal” weight may actually have more fat and less muscle than someone who is slightly heavier. For men over 60, being slightly above the traditional ideal (say, 180 to 185 at 5’11”) while maintaining muscle through regular activity may be healthier than being 160 pounds with little muscle mass. The priority shifts from hitting a number to preserving strength and preventing falls.
A Practical Way to Think About Your Weight
If you’re 5’11” and trying to figure out a reasonable target, start with the 155 to 179 pound range as a baseline for someone with average muscle mass. Adjust upward if you strength train regularly. Adjust downward if you have a naturally smaller frame and low muscle mass.
Then look beyond the scale. Measure your waist. If it’s under 35.5 inches and your waist-to-hip ratio is below 0.90, your weight is likely in a healthy place even if BMI says otherwise. If your waist exceeds those numbers, the distribution of your weight matters more than the total. Losing inches around the middle carries more health benefit than chasing a specific number on the scale.
