Free Ideal Weight Calculator | EveryCalc
The calculator uses multiple established formulas: the Devine Formula (1974), Robinson Formula (1983), Miller Formula (1983), and Hamwi Formula (1964). Each uses height and gender to estimate ideal weight, with adjustments for frame size (small, medium, large).
Ideal weight calculators provide a healthy target range based on your height and build. They help set realistic goals and provide a benchmark for assessing whether your current weight is in a healthy range for your body type.
While BMI provides a general healthy weight range (18.5-24.9), ideal weight formulas attempt to give a more specific target. Different formulas yield slightly different results, which is why the calculator shows multiple estimates.
Focus on body composition, not just scale weight. Build muscle through resistance training. Eat a balanced diet with adequate protein. Be patient - healthy weight loss is 1-2 pounds per week. Consult a healthcare provider before making major changes.
Ideal weight is estimated using several established medical formulas that factor in height and gender. The Devine formula (1974), Robinson formula (1983), Miller formula (1983), and Hamwi formula (1964) each use slightly different calculations. This calculator also shows a healthy BMI-based weight range (BMI 18.5-24.9) and adjusts results for body frame size (small, medium, or large). Since each formula yields a slightly different result, the calculator shows multiple estimates to give you a realistic range.
Ideal weight calculators provide general estimates based on population averages, not personalized health assessments. They do not account for muscle mass, bone density, body composition, or individual health factors. A muscular athlete may weigh more than the ideal range yet be perfectly healthy. These calculators work best as rough guidelines rather than strict targets. For a personalized assessment, consult a healthcare provider who can consider your full medical history, body composition, and fitness level.
Ideal weight ranges provide a useful starting reference, but they should not be your only health goal. Focus on overall health markers including body composition, blood pressure, blood sugar levels, cholesterol, energy levels, and physical fitness. A weight within the healthy BMI range (18.5-24.9) is generally recommended, but the specific number matters less than your overall well-being. Sustainable habits like regular exercise, balanced nutrition, and adequate sleep are more important than reaching an exact number on the scale.
