    How ideal weight ranges are calculated

    Several formulas exist for estimating ideal body weight (IBW). The most widely used clinically is the Devine formula (1974): Men: 50 kg + 2.3 kg per inch over 5 feet. Women: 45.5 kg + 2.3 kg per inch over 5 feet. For example, a 5'8" (172 cm) male has an IBW of 50 + (8 × 2.3) = 68.4 kg. These formulas were originally developed for pharmaceutical dosing, not fitness.

    A healthy weight range extends 10% above and below the calculated IBW for most individuals.

    Limitations of ideal weight formulas

    • Formulas don't account for frame size (small, medium, large bone structure), which can shift appropriate weight by 5–10 kg.
    • Muscle mass is ignored — a muscular individual may be 5–10 kg above "ideal" weight while having excellent health markers.
    • The formulas were validated primarily on Western populations. Indians tend to have higher body fat at similar weights, meaning the "ideal" may be 2–4 kg lower for South Asian populations.

    Rather than targeting a specific number on a scale, aim for a BMI in the 18.5–22.9 range (Indian population guidelines) alongside a waist circumference below 90cm (men) or 80cm (women). These composite metrics correlate better with metabolic health than any single weight formula.

    Frequently asked questions

    Is ideal weight the same as healthy weight?▼
    Ideal weight from formulas represents a statistical midpoint, not a rigid target. Healthy weight is a range — roughly ±10% of ideal weight — within which most people have good metabolic health markers. Someone 5 kg above 'ideal' weight with low waist circumference, good blood pressure, and normal blood sugar is healthier than someone at exact 'ideal' weight with central obesity.
    Why do I feel healthy at a weight higher than the 'ideal'?▼
    Because ideal weight formulas are blunt statistical tools. If your higher weight is composed primarily of muscle rather than fat, your health markers are likely fine. Body composition — the ratio of muscle to fat and where fat is distributed — matters more than the scale number for metabolic health.
    How do I account for frame size in ideal weight?▼
    Measure your wrist circumference: for 5'5"–5'7" height, wrist under 15.2 cm indicates small frame; 15.2–16.5 cm medium; above 16.5 cm large frame. For large frames, add 10% to the calculated ideal weight. For small frames, subtract 10%.
    Should my weight loss goal match the ideal weight formula exactly?▼
    Not necessarily. Set a goal that represents meaningful improvement in your health markers and is achievable. Losing 10–15% of body weight from an obese starting point produces major health improvements even if the target is still above 'ideal.' Use ideal weight as a long-term reference, not as the only acceptable outcome.
