Healthy Weight for Your Height: How to Estimate It

Want to know a healthy weight for your height? Multiply 18.5 and 24.9 by your height in meters squared to get the BMI healthy range.

The list below shows the range for common heights.

Healthy weight range by height

• 1.55 m: about 44.4 to 59.8 kg
• 1.6 m: about 47.4 to 63.7 kg
• 1.65 m: about 50.4 to 67.8 kg
• 1.7 m: about 53.5 to 72.0 kg
• 1.75 m: about 56.7 to 76.3 kg
• 1.8 m: about 59.9 to 80.7 kg
• 1.85 m: about 63.3 to 85.2 kg

How the range is calculated

Example: for a height of 1.70 m, 1.70 x 1.70 = 2.89. Multiply by 18.5 and by 24.9 and you get about 53.5 kg and 72.0 kg.

This is a general reference. Your ideal weight also depends on age, build and health conditions.

Why there is a range and not one ideal number

Bodies are different. Bone structure, muscle mass, age and genetics change what weight feels and works best for each person. That is why the BMI method gives a healthy range, not a single ideal number. Anywhere inside the range is considered a lower-risk weight on average.

How to calculate your own range

1. Convert your height to meters. For example, 168 cm becomes 1.68 m.
2. Multiply the height by itself. For 1.68 m this gives 2.8224.
3. Multiply that result by 18.5 to get the lower limit, which is about 52.2 kg.
4. Multiply the same result by 24.9 to get the upper limit, which is about 70.3 kg.
5. Your healthy weight range is between the two numbers.

Imperial units

If you use pounds and inches, the healthy range can be found by turning the BMI formula around: weight in pounds equals BMI times height in inches squared, divided by 703. Use 18.5 for the lower limit and 24.9 for the upper limit. A person 67 inches tall has a range of roughly 118 to 159 pounds.

Factors that change what is healthy for you

• Muscle mass: people who train with weights may sit at the upper end of the range or slightly above it and still be healthy.
• Age: older adults may need a little more reserve than younger adults.
• Frame size: people with a larger bone structure can be comfortable in the upper half of the range.
• Medical conditions: some illnesses and medicines affect weight and need professional guidance.

Setting realistic goals

If your weight is outside the range, avoid setting a goal that needs fast or extreme changes. Small steps are easier to keep, such as walking more days of the week, planning meals, cutting back on sugary drinks and sleeping better. A professional can help set a goal and a pace that fit your health and routine.

Quick answers

Is the lowest number of the range the best? Not necessarily. Being very close to the lower limit can be fine for some people and too low for others.

Should I try to reach the exact middle? There is no need. Staying inside the range is what matters.

Can I rely only on this page? It is a general reference. For decisions about your health, talk to a professional.

Healthy weight for women and men

The calculation is the same for both sexes, but the practical result can differ. Men usually carry more muscle mass, so many are comfortable in the middle or upper part of the range. Women usually have a higher percentage of body fat at the same weight, so a number near the lower or middle part of the range may feel better for some. These are only general patterns, and each person is different.

A simple routine to follow your weight

1. Pick one day each week, weigh yourself at the same time and with similar clothes.
2. Write the number down in a notebook or phone app.
3. Look at the average of four weeks instead of each single reading.
4. Check your BMI again once a month with the calculator.
5. Share the record with your doctor or nutritionist at your next visit.

Daily weight can swing by one or two kilos because of water, salt, meals and bowel habits, so a single day says very little. The trend over weeks is what counts.
