Ideal Weight Calculator
Last updated: 2026-06-25
Your ideal weight is the weight for your height at BMI 22 — generally considered the lowest-risk weight.
The formula is ideal weight(kg) = 22 × height(m) × height(m), and the healthy weight range covers BMI 18.5–24.9.
Calculate ideal weight from your height
Your ideal weight (BMI 22)
–
- Healthy weight range (BMI 18.5–24.9)
- –
- Difference from current weight
- –
Please enter a valid height.
How to use it
- Enter height — enter your height in centimeters (cm). Example: 168. (168 cm ≈ 5 ft 6 in.)
- Enter current weight (optional) — add your current weight to also see the difference from ideal.
- View result — press Calculate to see your ideal weight (BMI 22) and healthy weight range.
What is ideal weight?
Ideal (or healthy) body weight is the weight for your height at a BMI of 22, which is widely considered the point of lowest health risk. Multiple epidemiological studies report that a BMI around 22 is associated with the lowest mortality and chronic-disease risk, which is why it is commonly used as the reference value.
Ideal weight(kg) = 22 × height(m) × height(m)
Example: height 168 cm (=1.68 m) → 22 × 1.68 × 1.68 ≈ 62.1 kg
Quick ideal weight & healthy range by height
| Height (cm) | Ideal weight (kg) | Healthy range (kg) |
|---|---|---|
| 150 | 49.5 | 41.6 – 56.0 |
| 155 | 52.9 | 44.4 – 59.8 |
| 160 | 56.3 | 47.4 – 63.7 |
| 165 | 59.9 | 50.4 – 67.8 |
| 170 | 63.6 | 53.5 – 72.0 |
| 175 | 67.4 | 56.7 – 76.3 |
| 180 | 71.3 | 59.9 – 80.7 |
Things to keep in mind
- Ideal weight uses only your height, so it cannot account for muscle mass, frame size or body fat percentage.
- Anywhere within the healthy range (BMI 18.5–24.9) is considered a healthy weight — you don't need to hit the single ideal point.
- Being underweight (BMI below 18.5) carries risks, and being overweight or obese raises metabolic risk.

Frequently asked questions (FAQ)
How is ideal weight calculated?
This calculator uses a BMI of 22 as the reference: ideal weight = 22 × height(m) × height(m). For example, at 168 cm (1.68 m), 22 × 1.68 × 1.68 ≈ 62.1 kg.
What is the difference between ideal weight and a healthy weight range?
Ideal weight is the single point at BMI 22, generally considered the lowest-risk weight. The healthy weight range covers BMI 18.5–24.9. Being anywhere in that range is considered a healthy weight.
Why use a BMI of 22?
Several epidemiological studies have found that a BMI around 22 is associated with the lowest mortality and disease risk, which is why it is commonly used as the reference point for ideal weight.
Is being below ideal weight better?
Not necessarily. Being underweight (BMI below 18.5) carries risks such as weakened immunity, osteoporosis and muscle loss. It is best to stay within the healthy range while also considering your body fat percentage and overall condition.
