Ideal Weight for Height: Chart for Men and Women

Q: Does the ideal weight change as you age?

The BMI reference range does not change for adults (18+). However, muscle mass typically declines 1–2% per decade after 30, meaning older adults at the same BMI as younger adults likely have higher body fat. For people over 40, maintaining muscle through resistance training is often more important than a specific weight target.

What should you weigh for your height? The answer is not a single number — it is a range. This guide provides a complete ideal weight for height chart based on the BMI healthy range, plus estimates from the four most widely cited clinical formulas.

Ideal Weight for Height Chart (BMI Healthy Range)

The most clinically accepted definition of a healthy weight is a Body Mass Index (BMI) between 18.5 and 24.9. The table below translates this range into kilograms for heights from 150–195 cm. The healthy weight range is identical for men and women at the same height using BMI — individual ideal weight formulas differ slightly by sex and are shown separately below.

Height	Min (BMI 18.5)	Max (BMI 24.9)	Midpoint
150 cm (4'11")	41.6 kg	56.0 kg	48.8 kg
155 cm (5'1")	44.4 kg	59.8 kg	52.1 kg
160 cm (5'3")	47.4 kg	63.7 kg	55.6 kg
165 cm (5'5")	50.3 kg	67.7 kg	59.0 kg
170 cm (5'7")	53.5 kg	71.9 kg	62.7 kg
175 cm (5'9")	56.7 kg	76.3 kg	66.5 kg
180 cm (5'11")	60.0 kg	80.7 kg	70.4 kg
185 cm (6'1")	63.3 kg	85.2 kg	74.3 kg
190 cm (6'3")	66.8 kg	89.9 kg	78.4 kg
195 cm (6'5")	70.3 kg	94.6 kg	82.5 kg

Use the Ideal Weight Calculator for your exact height, or the BMI Calculator to see where your current weight sits relative to this range.

Formula Estimates by Sex

The four most widely used clinical ideal weight formulas produce sex-specific estimates. These were designed for pharmaceutical dosing and clinical settings — not fitness goals — but serve as useful reference points alongside the BMI range.

Height	Devine Male	Devine Female	Robinson Male	Robinson Female
160 cm	57.0 kg	52.5 kg	58.6 kg	55.7 kg
165 cm	59.3 kg	54.8 kg	60.5 kg	57.3 kg
170 cm	61.6 kg	57.1 kg	62.5 kg	58.8 kg
175 cm	70.5 kg	66.0 kg	68.9 kg	65.3 kg
180 cm	73.8 kg	69.3 kg	71.4 kg	67.4 kg
185 cm	77.1 kg	72.6 kg	74.0 kg	69.3 kg

Why a Range Is More Useful Than a Single Target

All four formulas give a point estimate — a single kilogram target. The BMI healthy range gives a window. For a 175 cm person, that window is approximately 56.7–76.3 kg — a span of nearly 20 kg. Being anywhere within this range is associated with lower risk of weight-related health conditions.

The key insight: two people at the same height and the same weight can have very different body compositions and health profiles. A 175 cm person at 70 kg with 15% body fat (mostly muscle) is in excellent health. A 175 cm person at 70 kg with 32% body fat (low muscle, high fat) is in a much higher-risk category — yet both fall within the "healthy" BMI range.

This is why body fat percentage is a more meaningful metric than ideal weight for most individuals. Use the BMI range as a starting reference, then measure body fat percentage to understand your body composition. The Body Fat Calculator and Lean Body Mass Calculator give you this fuller picture.

How to Use This Information to Set a Goal

If your current weight is above the BMI healthy range for your height, a gradual calorie deficit of 300–500 kcal/day will bring you into range over time. There is no need to rush — sustainable fat loss at 0.3–0.5 kg/week is more effective long-term than aggressive short-term dieting.

If your weight is within the range, your goal should shift from weight loss to body composition improvement: reducing body fat percentage and building lean mass. Weight may change little while body composition improves significantly.

If your weight is below the minimum, consult a healthcare provider — being underweight carries significant risks including bone density loss, hormonal disruption, and immune suppression.

Frequently Asked Questions

What is the ideal weight for a 170 cm person?

For a 170 cm person, the BMI healthy weight range is approximately 53.5–72.0 kg. Formula estimates vary: Devine gives 61.6 kg (male) / 57.1 kg (female); Robinson gives 62.5 kg (male) / 58.8 kg (female). The midpoint of the BMI range — around 62–63 kg — is a reasonable target for someone at average muscle mass. Muscular individuals may sit toward the higher end of the range and still be in excellent health.

What is the ideal weight for a 175 cm male?

For a 175 cm male, the BMI healthy range is 56.7–76.3 kg. Formula estimates: Devine = 70.5 kg, Robinson = 68.9 kg, Miller = 68.8 kg, Hamwi = 72.3 kg. A reasonable target for a moderately muscular male at 175 cm is 70–75 kg. For a leaner build with lower muscle mass, 65–70 kg may be more appropriate. Use the Ideal Weight Calculator for your exact inputs.

What is the ideal weight for a 165 cm female?

For a 165 cm female, the BMI healthy range is 50.3–67.7 kg. Formula estimates: Devine = 54.8 kg, Robinson = 57.3 kg, Miller = 59.0 kg, Hamwi = 56.0 kg. Most formula estimates cluster around 55–60 kg for a 165 cm woman. However, being anywhere in the 50–68 kg range is clinically considered healthy, and individual muscle mass affects where your personal ideal sits within that range.

Is the ideal weight the same for men and women at the same height?

The BMI healthy range is the same for men and women at the same height. However, the four formula estimates (Devine, Robinson, Miller, Hamwi) differ by sex — they typically give women lower target weights than men of the same height, reflecting average differences in muscle and bone mass. In practice, these differences are small (typically 3–8 kg), and the BMI range is the more useful clinical reference for both sexes.

Should I use the formula estimate or the BMI range as my target?

The BMI healthy range (18.5–24.9) is the more useful target because it gives you a realistic window rather than a single point. The formula estimates were designed for clinical drug dosing — not fitness goal-setting. Choose a target anywhere within your BMI healthy range based on your body composition goals and current muscle mass. Being within the range matters more than hitting a specific number.

What if I am muscular — does ideal weight still apply?

Not reliably. All ideal weight formulas and BMI ranges are based on height and sex only, without accounting for muscle mass. A muscular person at the upper end of the BMI healthy range — or even slightly above it — is not necessarily overweight in terms of health risk. Body fat percentage is a more relevant metric for muscular individuals. A 185 cm male at 90 kg with 12% body fat is in excellent health despite being at the top of the BMI healthy range.

How do I calculate the ideal weight range for any height?

Multiply the square of your height in metres by 18.5 (for the lower bound) and 24.9 (for the upper bound). For example, at 170 cm: 1.70² × 18.5 = 53.5 kg (minimum) and 1.70² × 24.9 = 71.9 kg (maximum). The midpoint is 62.7 kg. Alternatively, use the Ideal Weight Calculator for instant results with all four formula estimates displayed.

Does the ideal weight change as you age?

The BMI reference range does not change with age for adults (18+). However, body composition changes significantly with age — muscle mass typically declines by 1–2% per decade after age 30. This means an older person at the same BMI as a younger person likely has higher body fat and lower muscle mass. For people over 40, maintaining muscle through resistance training is often more important than hitting a specific weight target.

Medical Disclaimer: Ideal weight charts are population-level tools and may not reflect what is healthy for every individual. Factors including muscle mass, bone density, age, and ethnicity all affect healthy body weight. Consult a healthcare provider before making significant changes to your diet or exercise programme, especially if you are underweight or have a history of eating disorders.
