Frequently asked questions
How is ideal weight calculated here?
We use the Devine formula, one of the most widely used and referenced formulas for estimating ideal body weight from height and sex — originally developed for medical dosing calculations.
Is there really one 'ideal' weight?
Not really — this is a population-level estimate, and healthy weight varies significantly based on muscle mass, body frame, age, and overall health. It's a general reference point, not a personal target.
Why does the formula use height in inches over 5 feet?
The Devine formula was originally developed using imperial units, with a base weight for someone exactly 5 feet tall, adding a fixed amount per inch above that. We convert automatically if you enter height in centimetres.
Should I aim for this exact number?
Not necessarily. This is one reference point among several possible formulas, and actual healthy weight ranges are broader. A doctor can offer guidance based on your full health picture.
What is the ideal weight for someone 5'6" tall?
Using the Devine formula, ideal weight for someone 5'6" (168cm) is about 63.8 kg (140.7 lb) for men and 59.3 kg (130.7 lb) for women. See the chart above for other heights.
What is the ideal weight for a 5'10" male?
For a man 5'10" (178cm) tall, the Devine formula estimates an ideal weight of about 73.0 kg (160.9 lb).
How much does ideal weight increase per inch of height?
The Devine formula adds about 2.3 kg (roughly 5 lb) of ideal weight per inch of height above 5 feet, for both men and women — only the starting base weight (at exactly 5 feet) differs by sex.
About this tool
