A good weight for a 5’10 male falls roughly between 144 and 180 pounds, depending on your build and body composition. That range comes from insurance actuarial data tied to longevity, and it lines up closely with the BMI “normal weight” window of about 129 to 174 pounds. But a single number on a scale tells you less than you might expect. Where you carry your weight, how much of it is muscle, and how old you are all shift what “good” actually means for your health.
The Standard BMI Range
Body mass index is still the most common screening tool. It divides your weight in kilograms by your height in meters squared. For a 5’10 male, the World Health Organization’s normal BMI range of 18.5 to 24.9 translates to roughly 129 to 174 pounds. A BMI of 25 or above is classified as overweight, and 30 or above is classified as obese.
Those cutoffs are population-level guidelines, not personalized diagnoses. They work reasonably well for identifying risk in large groups, but they can’t distinguish between someone carrying 180 pounds of muscle and someone carrying 180 pounds with a 42-inch waist. That’s why most clinicians now pair BMI with at least one other measurement.
Frame Size Changes the Target
Your bone structure genuinely affects what you should weigh. The Metropolitan Life Insurance tables, which were built from mortality data on hundreds of thousands of policyholders, break the healthy range for a 5’10 male into three categories based on frame size:
- Small frame: 144 to 154 pounds
- Medium frame: 151 to 163 pounds
- Large frame: 158 to 180 pounds
If you’re curious about your frame size, there’s a simple method. Extend your right arm straight out, bend the elbow to 90 degrees with your fingers pointing up, and measure the widest point across your elbow joint. For a man around 5’10 (roughly 172 to 181 cm), an elbow breadth between about 6.9 and 7.6 cm indicates a medium frame. Narrower means a small frame, wider means a large frame. You can approximate this with your thumb and index finger wrapped around the opposite wrist: if they overlap easily, you likely have a small frame; if they barely touch, medium; if they don’t meet, large.
Why Waist Size Matters More Than Scale Weight
Two men can both weigh 175 pounds at 5’10 and have very different health profiles. The difference often comes down to where the fat sits. Visceral fat, the deep abdominal fat that surrounds your organs, is far more metabolically dangerous than fat stored under the skin on your arms or legs. It raises the risk of high blood pressure, heart disease, type 2 diabetes, sleep apnea, stroke, fatty liver, and certain cancers.
The NHS recommends keeping your waist measurement below half your height. At 5’10 (70 inches), that means staying under 35 inches. The Mayo Clinic uses a slightly more lenient threshold: a waist measurement over 40 inches signals an unhealthy concentration of belly fat and meaningfully higher disease risk. Think of 35 inches as a good target and 40 inches as a red flag.
You can measure your waist at home with a flexible tape. Wrap it around your bare abdomen at the level of your navel, standing relaxed without sucking in. Take the reading after a normal exhale.
Body Fat Percentage vs. Body Weight
Scale weight lumps together muscle, bone, water, and fat. Body fat percentage separates them, giving a clearer picture of health risk. A 2025 study using US national survey data defined overweight for men as a body fat percentage of 25% or higher, and obesity as 30% or higher. There’s no universally agreed-upon “ideal” number, but staying below 25% puts most men in a healthy range.
Body fat percentage also explains why BMI sometimes misleads. A man who lifts weights regularly might weigh 190 pounds at 5’10 and register a BMI of 27.3 (technically overweight) while carrying only 15% body fat. Researchers use a metric called the fat-free mass index to assess muscularity independent of fat. The average across competitive male athletes is about 22.1, with strength and power athletes sitting higher and endurance athletes lower. If your extra weight comes from muscle rather than fat, BMI overstates your risk.
You can estimate body fat with a bathroom scale that uses bioelectrical impedance (common in smart scales), skinfold calipers, or a DEXA scan at a clinic. Smart scales are convenient but can vary by several percentage points depending on hydration. DEXA is the most accurate option if you want a reliable baseline.
How Age Shifts the Target
The relationship between weight and mortality changes as you get older. In younger adults, the lowest death rates line up with a BMI in the normal range. But in adults over 65, the picture shifts. A large study tracking elderly men and women found that the lowest mortality was in the 25 to 29.9 BMI range, which for a 5’10 male corresponds to about 174 to 209 pounds. People in every BMI category below 25 actually had higher death rates than those in the “overweight” zone.
The reasons are practical. Carrying slightly more weight in older age provides a metabolic reserve during illness or surgery. Being underweight is linked to loss of muscle mass (including the muscles that support breathing), a weakened immune response, and higher death rates during hospitalization. For a 5’10 male over 65, a weight in the mid-170s to low 190s may be healthier than the 150s, provided the waist stays in check.
Body fat also naturally increases with age even if weight stays stable, because muscle mass gradually declines. Staying active with resistance exercise matters more than hitting a specific number on the scale as you get older.
Putting It All Together
If you’re a 5’10 male looking for a single target, 150 to 175 pounds is a solid range for most adults under 65 with average muscle mass. But the most useful assessment combines three things: a scale weight that puts you in or near a normal BMI, a waist circumference under 35 inches, and a body fat percentage below 25%. Hitting all three is a stronger signal of good health than any one number alone.
If you’re muscular, give yourself room above the standard BMI range and rely more on waist and body fat measurements. If you’re over 65, don’t panic about a BMI of 26 or 27. The data suggests that’s a comfortable place to be, as long as belly fat isn’t climbing. The “right” weight is ultimately the one where your blood pressure, blood sugar, and energy levels are solid and your waist stays proportional to your frame.
