Ideal Weight Calculator – Find Your Healthy Weight
Your ideal weight isn't a single number — it's a range. This calculator uses your height and gender to determine the healthy weight window that minimises your risk of weight-related health conditions.
How to Calculate Your Ideal Weight
Ideal weight is derived from BMI. A "healthy" BMI falls between 18.5 and 24.9. By working backwards from these thresholds, we can calculate the weight range that puts any given height in the healthy zone.
For example, someone 170 cm tall has a healthy weight range of approximately 53.5 kg to 71.9 kg.
BMI and Weight Relationship
The relationship between height and healthy weight is not linear — as height increases, the healthy weight range grows more quickly (because it scales with height squared). This is why the same absolute weight can be healthy for a tall person but overweight for a shorter individual.
Tips to Reach Your Ideal Weight
Safe weight loss is 0.5–1 kg per week. Losing too fast can cause muscle loss and nutrient deficiencies.
Reduce daily intake by 300–500 calories through diet changes rather than extreme restriction. Use our Calorie Calculator to find your target.
Cardio burns calories; strength training preserves and builds muscle, which raises your resting metabolism.
Weigh yourself weekly under consistent conditions. Use BMI alongside waist measurements for a fuller picture.
