A healthy weight range estimate uses a person's height and a reference BMI interval. It is a broad guide for adults, not a fixed ideal weight or a personal medical target.

How is a healthy weight range estimated?
For adults, a commonly used reference BMI interval is 18.5 to 24.9. To estimate the corresponding weight range, multiply each BMI limit by height in metres squared.
Lower estimate = 18.5 × height (m)². Upper estimate = 24.9 × height (m)².
Example: estimated range for 175 cm
Convert 175 cm to 1.75 m. Square the height: 1.75 × 1.75 = 3.0625. Multiply by 18.5 for the lower estimate and 24.9 for the upper estimate.
The estimated range is approximately 56.6 kg to 76.2 kg. This is a mathematical reference based on adult BMI cut-offs, not an individual target.
Why height matters
The BMI formula relates weight to height squared. This means the same body weight can correspond to different BMI values for people of different heights.
Use an accurate height measurement without shoes. Small measurement differences can change the calculated estimate.
Why there is no single ideal weight
Health is influenced by more than height and weight. Age, body composition, pregnancy, medical conditions, medicines and personal circumstances can all matter.
A healthcare professional can help set an appropriate goal if weight management is relevant to your health.
Calculate your estimated range online
Enter your height and weight in the InfoJano BMI Calculator to view your BMI result and the estimated adult weight range associated with the standard reference interval.
The calculator does not show an adult healthy-weight range for users under 20 because child and teen BMI requires age- and sex-specific interpretation.

? Frequently Asked Questions
How do I calculate a healthy weight range by height?
Convert height to metres, square it, then multiply by 18.5 and 24.9 to estimate the lower and upper adult reference weights.
What is the healthy weight range for 175 cm?
Using the adult BMI reference interval 18.5–24.9, the estimate is approximately 56.6–76.2 kg.
Is the BMI healthy weight range an ideal weight?
No. It is a general mathematical estimate, not a personal ideal or treatment target.
Can this range be used for children?
No. Children and teenagers require age- and sex-specific BMI interpretation.
Why can two people at the same weight have different BMI values?
BMI includes height in its formula, so different heights produce different BMI values at the same weight.
Healthy weight by height keywords
A healthy weight range by height can be estimated from the adult BMI reference interval. It is a broad screening estimate, not a personal ideal weight or a target that suits every body type. Age, muscle mass, pregnancy, health conditions and clinical context can affect how weight should be assessed.
