Ideal Weight Calculator by Height: kg and lbs Chart
Find a healthy weight range for your height using BMI guidelines, then compare the result in kilograms and pounds. Use the chart for a quick estimate and the calculator for your exact height.
Quick answer: what is a healthy weight range?
A BMI-based healthy range uses BMI 18.5 to 24.9. For example, at 170 cm, the range is roughly 53.5 to 72.0 kg. Muscle mass, waist size, age, and medical context still matter.

Ideal Weight Chart by Height (4'10" to 6'6")
This chart presents BMI-based healthy weight reference ranges (18.5–24.9) alongside historical height-based Devine estimates for both men and women.

How We Calculate Ideal Weight
This calculator uses the BMI (Body Mass Index) method to determine a healthy weight range:
Lower bound: BMI of 18.5 (lower edge of healthy range)
Midpoint: BMI of 21.7 (midpoint of healthy range)
Upper bound: BMI of 24.9 (upper edge of healthy range)
The formula: Weight = BMI × height² (in metres)
For example, at 170 cm: Lower = 18.5 × 1.70² = 53.5 kg, Upper = 24.9 × 1.70² = 71.9 kg
Important Note
The "ideal" weight range is based on BMI, which has limitations — it does not account for muscle mass, age, bone density or body composition.
Some people may have a perfectly healthy body composition while sitting outside this range (e.g., athletes with high muscle mass). Use this as a general reference, not an absolute target.
For a more complete view, combine this with a BMI calculation and body fat estimate.
How the Calculation Works
Asterisks Fit ideal weight references combine CDC adult BMI category boundaries with historical height-based ideal-body-weight equations:
- CDC Adult BMI Categories: Supports the BMI category boundaries used for the BMI-derived reference range (18.5 to 24.9 kg/m² for the healthy-weight category). CDC does not validate the historical Devine estimate.
- Devine Formula (1974): A historical height-based estimate originally developed for medication dosing context. It is included as a historical reference estimate, not as a CDC-validated healthy-weight standard:
Men: IBW = 50.0 kg + 2.3 kg per inch over 5 feet
Women: IBW = 45.5 kg + 2.3 kg per inch over 5 feet - Context & Skeletal Frame Size: Historical formulas are linear approximations and do not account for differences in bone density, skeletal frame width, muscular development, age or body composition.
