About BMI Calculator: Ideal Weight

CALCULATE YOUR BMI INSTANTLY
Enter your height and weight to see your BMI, category, and a clear healthy-weight range in seconds. Choose WHO or DGE classification, switch between metric, imperial, or stone units, and get a dedicated result for kids and teens.

TRACK YOUR PROGRESS
Every calculation is saved to your personal history. Watch your trend on a simple chart, set a goal weight, and see your start, current, goal, and average all in one place.

KNOW YOUR NUMBERS
Go beyond BMI with Body Metrics:
• BMR & TDEE: Base metabolic rate and daily calorie needs.
• Body Fat Percentage.
• Waist-to-Hip Ratio with a clear risk level evaluation.
All calculated instantly from the measurements you already entered!

A simple daily challenge keeps you checking in—water, walking, sleep, mindful eating—with streaks that reward consistency, not perfection.
