Frequently asked questions

Which formula is best?

None is best. They were made for different purposes and give different answers, so use them as a rough guide. The healthy BMI range (18.5 to 24.9) is the most widely used.

Why does my height matter so much?

All the formulas add a set number of kilograms for each inch above 5 feet.

Is there one ideal weight?

No. A healthy weight depends on frame size, muscle, age and health. General guidance for adults, not medical advice.

Do the formulas work for short adults?

They were designed for adults above 5 feet (152 cm), so they are less reliable below that. The BMI range still works.
