Quick Answer
How much should I weigh for my height?
A healthy weight depends on your height, age, gender, and body frame. For adults, a BMI of 18.5–24.9 is considered normal. For example, a 5'6" person should weigh between 115–154 lbs (52–70 kg), while a 5'10" person should weigh between 129–174 lbs (59–79 kg). Use clinical formulas like Devine, Robinson, Miller, or Hamwi for a more personalised ideal weight estimate.

Key Takeaways
- 1Healthy weight is a range, not a single number — it depends on height, age, gender, muscle mass, frame size, and ethnicity.
- 2For adults, a BMI of 18.5–24.9 corresponds to the healthy weight range for any given height.
- 3Clinical formulas (Devine, Robinson, Miller, Hamwi) give specific ideal weight estimates that vary by 5–10 lbs.
- 4Adults over 65 may benefit from a slightly higher BMI of 23–28 for protective health effects.
- 5Waist circumference and body fat percentage provide more complete health information than weight alone.

How Much Should I Weigh?
"How much should I weigh?" is one of the most frequently asked health questions in the world, and with good reason — your body weight has a profound impact on your energy levels, disease risk, joint health, mental wellbeing, and longevity. Yet the answer is far more nuanced than a single number on a scale. Your ideal weight depends on your height, age, gender, body frame, muscle mass, ethnicity, and individual health history.
This comprehensive guide explores every factor that determines your healthy weight range, provides detailed charts for men and women, compares multiple clinical formulas, and helps you set realistic, evidence-based weight goals. For a quick personalised answer, use our [BMI calculator](/) or [ideal weight calculator](/ideal-weight-calculator).
Why There Is No Single "Right" Weight
Before looking at any chart, it is important to understand that healthy weight is a **range**, not a fixed point. Two people of the same height and gender can have very different healthy weights depending on:
The charts and formulas below provide evidence-based ranges, but they should always be interpreted alongside other health markers and, ideally, with input from a healthcare professional.
Healthy Weight Charts by Height
The following charts show the healthy weight range for adults based on a BMI of 18.5–24.9, which the World Health Organization classifies as "normal weight."
Women's Ideal Weight by Height

Men's Ideal Weight by Height
| Height | Healthy Weight Range | Midpoint |
|---|---|---|
| 5'2" (157 cm) | 101–136 lbs (46–62 kg) | 119 lbs (54 kg) |
| 5'3" (160 cm) | 104–140 lbs (47–64 kg) | 122 lbs (55 kg) |
| 5'4" (163 cm) | 108–145 lbs (49–66 kg) | 127 lbs (57 kg) |
| 5'5" (165 cm) | 111–149 lbs (50–68 kg) | 130 lbs (59 kg) |
| 5'6" (168 cm) | 115–154 lbs (52–70 kg) | 135 lbs (61 kg) |
| 5'7" (170 cm) | 118–159 lbs (54–72 kg) | 139 lbs (63 kg) |
| 5'8" (173 cm) | 122–164 lbs (55–74 kg) | 143 lbs (65 kg) |
| 5'9" (175 cm) | 125–168 lbs (57–76 kg) | 147 lbs (67 kg) |
| 5'10" (178 cm) | 129–174 lbs (59–79 kg) | 152 lbs (69 kg) |
| 5'11" (180 cm) | 133–179 lbs (60–81 kg) | 156 lbs (71 kg) |
| 6'0" (183 cm) | 137–184 lbs (62–83 kg) | 161 lbs (73 kg) |
| 6'1" (185 cm) | 140–189 lbs (64–86 kg) | 165 lbs (75 kg) |
| 6'2" (188 cm) | 144–194 lbs (65–88 kg) | 169 lbs (77 kg) |
| 6'3" (191 cm) | 148–199 lbs (67–90 kg) | 174 lbs (79 kg) |
| 6'4" (193 cm) | 152–204 lbs (69–93 kg) | 178 lbs (81 kg) |
| 6'5" (196 cm) | 156–210 lbs (71–95 kg) | 183 lbs (83 kg) |
While these ranges are identical for men and women at any given height (because the underlying BMI thresholds are the same), men typically fall in the upper portion of the range due to greater average muscle mass and bone density.
Clinical Formulas for Ideal Weight
Healthcare professionals use several established formulas to estimate ideal body weight. Each produces a slightly different result because they were developed in different populations and time periods.
Devine Formula (1974)
The most commonly used formula in pharmacology and clinical medicine:
Example: A 5'8" man: 50 + (2.3 × 8) = 50 + 18.4 = 68.4 kg (151 lbs)
Robinson Formula (1983)
A refinement of the Devine formula with slightly different coefficients:
Miller Formula (1983)
Tends to produce lower estimates, which some consider more appropriate for modern populations:
Hamwi Formula (1964)
One of the earliest ideal weight formulas, still referenced in dietetics:
Which Formula Should You Use?
No single formula is definitively "best." The BMI-based range (18.5–24.9) provides the widest window, while the Devine formula gives a specific point estimate that serves as a useful reference. Our [ideal weight calculator](/ideal-weight-calculator) shows results from all four formulas simultaneously so you can compare them and select the range that makes sense for your body type and goals.
How Age Affects Your Ideal Weight
Ages 20–39: The Reference Range
Standard BMI categories and ideal weight formulas are most reliable for this age group. Muscle mass is typically at or near peak levels, metabolic rate is relatively high, and the established healthy weight ranges apply most directly.
Ages 40–59: Gradual Body Composition Shift
Beginning in your 30s and accelerating through your 40s and 50s, muscle mass naturally declines at approximately 3–8% per decade (a process called sarcopenia). This means:
Ages 60+: The Protective Effect of Slightly Higher Weight
Multiple large-scale studies have found that older adults with a BMI in the range of **23–28** may actually have better survival outcomes than those with a BMI of 18.5–22. This observation is likely because:

Body Frame Size and What It Means for Your Weight
Your skeletal frame size significantly affects where you should fall within the healthy weight range. A large-framed person will naturally (and healthily) weigh more than a small-framed person of the same height.
How to Determine Your Frame Size
Wrist measurement method:
Wrap your thumb and middle finger around your non-dominant wrist at the narrowest point:
Frame Size Weight Adjustments
**Example:** A 5'6" woman with a healthy range of 115–154 lbs:
Ethnicity and Healthy Weight
Health risks at different weights vary across ethnic groups, and global health organisations increasingly recognise that one-size-fits-all thresholds are insufficient:
South Asian, Chinese, and Japanese Populations
People of Asian descent tend to carry more visceral (organ-surrounding) fat at lower body weights. Adjusted thresholds recommended by many Asian health authorities:
This means a South Asian individual should aim for the lower end of Western healthy weight ranges.
Black and African-Caribbean Populations
Research shows these populations tend to have greater bone density and lean muscle mass on average. A BMI in the standard overweight range (25–29.9) may carry less metabolic risk for this group compared to other populations.
Pacific Islander and Polynesian Populations
Similar to Black populations, greater average bone density and muscle mass mean higher BMI thresholds may be more appropriate.
Metrics Beyond the Scale
The number on the scale tells an incomplete story. These additional measurements provide a more comprehensive picture of whether your weight is truly healthy:
Waist Circumference
Arguably the single most useful additional measurement. Excess fat stored around the midsection (visceral fat) is metabolically dangerous regardless of overall weight.
Increased risk thresholds:
Waist-to-Height Ratio
A simple rule: **keep your waist circumference below half your height.** Research suggests this ratio is a better predictor of cardiovascular risk than BMI alone.
Body Fat Percentage
Directly measures the proportion of your body that is fat. Our [body fat calculator](/body-fat-calculator) uses the US Navy method for a quick at-home estimate.
**Healthy ranges for men:** 10–20% (ages 20–39), up to 24% (ages 40–59), up to 28% (ages 60+)
**Healthy ranges for women:** 18–28% (ages 20–39), up to 32% (ages 40–59), up to 36% (ages 60+)
BMI
While BMI has limitations (it cannot distinguish fat from muscle), it remains a useful first-line screening tool. Use our [BMI calculator](/) for instant results.
Why the Scale Fluctuates Day to Day
If you weigh yourself regularly, you will notice your weight can vary by 1–3 kg (2–6 lbs) from one day to the next. This is completely normal and almost entirely due to:
**How to track accurately:** Weigh yourself every morning at the same time (after using the bathroom, before eating) and calculate a **7-day rolling average**. Judge progress by the trend of your weekly averages, not by any single daily reading.

When to See a Doctor About Your Weight
Consult a healthcare professional if:
A doctor can combine your weight data with blood tests, body composition measurements, blood pressure, and your personal health history to give a truly individualised assessment.
The Bottom Line
There is no single perfect weight for any height — healthy weight is a range influenced by your age, gender, frame size, muscle mass, ethnicity, and individual health profile. Use the charts and formulas in this guide as a starting framework, then refine your personal target using body composition measurements, waist circumference, and professional medical advice.
Start with these tools:
The number on the scale is one data point in a much larger picture. Focus on building healthy habits — consistent exercise, balanced nutrition, adequate sleep, and regular health monitoring — and your weight will settle into the range that is right for your body.

Frequently Asked Questions
Quick answers to the most common questions
A sensible rate is 0.5 to 1 kg (1 to 2 lbs) per week, achieved through a daily calorie deficit of around 500 calories. Faster loss tends to strip away muscle as well as fat and is much harder to maintain long term. If you have a lot of weight to lose, the first few weeks may show bigger drops thanks to water and glycogen, but the weekly average soon settles into the sustainable range.
Yes, mildly. From your 30s onwards muscle mass naturally drops by 3 to 8 percent per decade, so a stable scale weight can hide a shift toward more body fat. After age 65 a slightly higher BMI of 23 to 28 is associated with better survival, partly because energy reserves help you cope with illness or surgery. Aim to preserve muscle through resistance training rather than chasing your twenties weight.
Ideal weight usually refers to a single number produced by a clinical formula such as Devine or Robinson, often used for medication dosing. Healthy weight is a wider range — typically the BMI window of 18.5 to 24.9 for your height — that accounts for normal variation in muscle, frame size, and body composition. For most people the healthy range is the more useful target.
Daily weighing at the same time each morning and tracking a seven-day rolling average gives the most accurate picture, because it smooths out normal fluctuations from food, salt, and hormones. Once-weekly weighing also works if daily numbers feel stressful. The single rule that matters: judge progress by the trend across several weeks, not by any individual reading.
Day-to-day swings of 1 to 3 kg (2 to 6 lbs) are normal and almost entirely water. Salt, carbohydrate intake, hormonal cycles, intense exercise, and the weight of food still being digested all shift the scale. A glass of water alone weighs about half a kilogram. None of this reflects fat gain or loss, which only becomes visible across weeks.
Less so. Muscle is denser than fat, so strength athletes and regular gym-goers often sit in the upper part of the healthy range or even cross into overweight by BMI without carrying excess fat. A waist measurement under 94 cm for men or 80 cm for women, plus a body fat reading in the healthy range, gives a much truer picture for muscular bodies.
People with larger skeletons should target the upper quarter of the healthy weight range for their height. For example, a 5'6" woman with a healthy span of 115 to 154 lbs would aim for roughly 143 to 154 lbs as a large-framed individual. Check your frame by wrapping your thumb and middle finger around the opposite wrist — if they do not meet, you have a larger frame.
Speak to a healthcare provider if your BMI drops below 18.5, if you have lost more than 5 percent of your body weight in 6 to 12 months without trying, or if low weight comes with persistent fatigue, hair loss, frequent illness, or missed periods. These can signal thyroid issues, malabsorption, disordered eating, or other conditions that need investigating rather than just more calories.
