Distance from the healthy range
The healthy band comes from the WHO BMI range of 18.5 to 24.9, which spans roughly 17 kilograms at average adult height. BMI cannot separate muscle from fat, so trained athletes routinely read as overweight while carrying very little. There is no health reason to prefer one end of the range.
Quick Tool Overview
The Healthy Weight Calculator gives the weight range considered healthy for your height, from the WHO BMI band of 18.5 to 24.9. Frame size from wrist circumference adjusts the range, and your current weight is placed on it with the gap to each end.

About the Healthy Weight Calculator
Work out the weight range considered healthy for your height, based on the World Health Organization BMI bands of 18.5 to 24.9. The range is adjusted for frame size using wrist circumference, and your current weight is placed on it.
A range is the honest answer here, because there is no single correct weight for a given height. The healthy band for someone 175 centimetres tall spans roughly 17 kilograms, and where you sit inside it depends on build, muscle mass and what you can hold comfortably. BMI is a population screening tool that cannot distinguish muscle from fat, so a muscular person may read as overweight while carrying very little; the calculator says so on the page rather than presenting the band as a verdict.
Key features of the Healthy Weight Calculator
A range, because there is no single answer
The healthy band at 175 centimetres spans about 17 kilograms, and the tool shows the whole thing rather than picking one number.
Frame size adjustment
Wrist circumference shifts the range up or down a few kilograms, which matters at the edges of the band.
Your position on the band
Current weight is plotted with the distance to each threshold, in kilograms or pounds.
Honest about BMI limits
The page states plainly that BMI cannot separate muscle from fat, so athletes should not treat the band as a verdict.
Both unit systems
Centimetres and kilograms, or feet, inches, pounds and stone.
How to use the Healthy Weight Calculator
-
1
Enter your height
In centimetres or feet and inches.
-
2
Add your current weight
Optional, but it places you on the range and shows the gap to each end.
-
3
Measure your wrist
Optional. Wrist circumference gives a frame size, which shifts the range up or down slightly.
-
4
Read the range
The healthy band in your units, plus the BMI thresholds it comes from.
Frequently asked questions
A BMI between 18.5 and 24.9 is the usual healthy band. For someone 175 centimetres tall that is roughly 57 to 76 kilograms, which is a wide range by design.
Modestly. A large frame shifts the sensible range up by a few kilograms and a small frame down, which is enough to matter at the edges of the band but not to redefine it.
No. BMI cannot separate muscle from fat, so trained athletes frequently score as overweight while carrying low body fat. Use a body fat estimate instead.
There is no health reason to prefer one end. Choose a weight you can maintain without constant restriction, since sustainability predicts long-term outcomes better than the number itself.
