A healthy weight range is defined by a BMI between 18.5 and 24.9. This range is associated with lower risk of weight-related health issues. However, individual health varies—consult a healthcare professional for personalised advice.

What is the Healthy Weight Calculator?
A healthy weight range is the band of body weight that corresponds to a Body Mass Index (BMI) between 18.5 and 24.9 for a given height. It's a screening tool used by health professionals to assess whether your weight is in a balanced range relative to your size. The healthy range accounts for natural variation—two people of the same height may have different healthy weights depending on muscle mass, bone density, and fitness level.
How it works
Enter your height in either centimetres (metric) or feet and inches (imperial). The calculator converts height to metres, applies the BMI formula, and computes the minimum weight (BMI 18.5) and maximum weight (BMI 24.9) for that height. It also shows the midpoint of your range and displays all values in your preferred unit system.
Min weight (kg) = 18.5 × height (m)² | Max weight (kg) = 24.9 × height (m)²
The healthy weight range is derived from the BMI formula. BMI = weight (kg) ÷ [height (m)]². Rearranged, min weight = 18.5 × height², and max weight = 24.9 × height². For imperial units, multiply the result by 2.20462 to convert kilograms to pounds.

Notes
Height: 170 cm
Healthy weight range: 53.5–71.6 kg (118–158 lb)
At 170 cm, a weight between these bounds corresponds to a BMI in the healthy range, lowering risk for weight-related chronic disease.
Height: 5'9" (175 cm)
Healthy weight range: 56.7–76.3 kg (125–168 lb)
Taller heights expand the range; muscle mass may push you higher while still staying healthy.
Height: 160 cm
Healthy weight range: 47.4–63.6 kg (104–140 lb)
Shorter heights produce narrower ranges; precise measurement is important for accuracy.
How to use the Healthy Weight Calculator
Toggle between metric (cm, kg) and imperial (ft, lb) units to match your measurement system.
Enter your height—in centimetres for metric, or feet and inches for imperial.
The calculator instantly displays your healthy weight range (BMI 18.5–24.9).
Review the range and your midpoint weight to understand your target.
Check the stats to see the boundary weights (BMI 18.5 and 24.9) and your exact height.
Use this range as a guide for nutrition and fitness goals; consult a doctor for personalised targets.

Tips & common mistakes
Common mistakes
Assuming your healthy weight is a single number, not a range—the range accounts for muscle, bone, and fitness variation.
Using outdated or inaccurate height measurements; measure without shoes, standing against a wall.
Ignoring that BMI is a screening tool, not a medical diagnosis—athletes with high muscle may be at a higher BMI but still healthy.
Not accounting for age, ethnicity, or medical history; consult a healthcare provider for individual circumstances.
Tips
Measure your height in the morning without shoes for the most accurate baseline.
Remember that your healthy range is broad—any weight within it is reasonable; precision beyond the range is unnecessary.
Combine your healthy weight range with fitness assessments (waist circumference, cardio fitness, strength) for a holistic health picture.
If your current weight is outside the range, aim for gradual change—1–2 pounds per week is sustainable and safe.
Frequently asked questions
Is the healthy weight range the same for everyone at my height?
The BMI-based range is the same, but individual healthy weights vary. Athletes may be heavier due to muscle; those with medical conditions may need different targets. Use the range as a starting point and consult a doctor for your specific situation.
What if my weight is above the range?
If you're above the healthy range, gradual weight loss—through a modest calorie deficit and regular activity—is recommended. Aim for 1–2 pounds per week. A doctor or registered dietitian can create a plan tailored to your health and goals.
What if my weight is below the range?
If you're below the range, consult a healthcare provider to rule out underlying health issues. Weight gain may be needed, typically through nutrient-dense foods and strength training to build muscle.
How accurate is the healthy weight calculator?
The calculator uses the standard BMI formula and is accurate for height–weight conversions. However, BMI doesn't account for muscle, bone density, age, or ethnicity—so it's a screening tool, not a medical diagnosis. Discuss your individual health with a doctor.
Should I aim for the midpoint of my healthy weight range?
Not necessarily. The midpoint is one reference point; anywhere within your healthy range is fine. Your ideal weight depends on fitness level, muscle mass, and how you feel—aim for a weight at which you're energetic and healthy.
How often should I calculate my healthy weight range?
Calculate it once unless your height changes (rare in adults). If you're actively working on weight loss or gain, track your progress monthly rather than daily, which can cause unnecessary anxiety.
