Overview
This tool shows the weight boundaries for each BMI category at a given height. It helps explain the reference chart, but it does not replace an assessment that includes waist circumference, body composition and health history.
Formula
Reference weight at a threshold = BMI threshold × height in meters squared. The healthy range lies between 18.5 and 24.9 (or 22.9 with Asia-Pacific cut-offs).
How it works
Enter your height
Choose metric or imperial before entering the value.
Choose the cut-offs
WHO cut-offs are the most common; Asia-Pacific cut-offs are lower.
Read the weight ranges
Each range maps to a category, and not every weight inside a range suits every person.
Worked examples
170 cm with WHO cut-offs
The healthy range is about 53.5–72.0 kg, and the obesity threshold is 86.7 kg.
160 cm with Asia-Pacific cut-offs
The healthy range is about 47.4–58.6 kg, and overweight starts at 58.9 kg.
Frequently asked questions
Does one range fit everyone?
No. Muscle mass, age, sex and body composition affect a suitable weight. Treat this as a general reference only.
Why are Asia-Pacific cut-offs different?
Studies found cardiometabolic risk at lower BMI in some Asian populations, so several countries use lower thresholds.
Can I use it for children?
No. Children and adolescents use growth charts based on age and sex.
Does a weight inside the range mean I am healthy?
Not necessarily. The range says nothing about blood pressure, blood sugar, lipids or fitness.
