About this Ideal weight calculator
“Ideal weight” formulas were built for population averages and clinical dosing rules — not as a personal destiny number. They still help frame a sensible range.
We show the Devine ideal body weight (common in clinical settings) and the weight band that corresponds to BMI 18.5–24.9 at your height.
Muscle mass, bone structure, and health goals matter more than matching a single formula. Use this as orientation, then personalise with a coach or clinician.
An ideal weight calculator should show more than one rigid number. Habbeat gives the Devine ideal body weight estimate and the BMI 18.5–24.9 healthy weight window for your height so you see a range, not a single verdict.
Searches for “ideal body weight calculator” and “healthy weight for my height” convert when results are transparent about formula limits and next steps.
Set goals with performance, labs, and sustainability in mind — then use Habbeat habits (food, movement, sleep) to move toward them gradually.
How to use this free tool
- Enter sex, height, and optionally current weight.
- We calculate Devine IBW and the BMI-normal weight window.
- If you add current weight, we plot where you sit relative to that window.
Worked examples
- Example: Devine IBW for a woman 5′5″ ≈ 45.5 kg + 2.3×5 ≈ 57 kg — one reference, not a destiny weight.
- Example: At 175 cm, the adult BMI 18.5–24.9 band spans a wide kg window; landing inside the band still leaves room for preference and sport.
- Example: A strength athlete may thrive above “ideal” IBW while remaining metabolically healthy — context wins.
Practical tips
- If you are muscular, prefer strength, waist, and how clothes fit over chasing Devine alone.
- Smaller weekly weight changes (~0.25–0.5% of body weight) are easier to sustain than aggressive cuts.
- Revisit targets after major training blocks — lean mass changes the picture.
Limitations & caveats
- Devine and BMI ranges are population tools, not personal prescriptions.
- Muscle mass and frame size change what “healthy” looks like.
- Eating disorders and medical diets need specialist care.
Frequently asked questions
What is the Devine formula?
For adults 5 ft and taller: men 50 kg + 2.3 kg per inch over 5 ft; women 45.5 kg + 2.3 kg per inch over 5 ft. Shorter heights are outside the classic formula’s design.
Which number should I aim for?
Prefer the healthy BMI range as a broad band, then refine with performance, labs, and preference. Devine is one reference point among several (Robinson, Miller, etc.).
Is ideal weight the same as goal weight?
Not necessarily. Goal weight should reflect sport, aesthetics you can maintain, and medical advice — not only a formula.
What is ideal body weight used for?
Clinically, IBW formulas sometimes guide medication dosing or nutrition references. For lifestyle goals, prefer a healthy range plus how you feel and perform.
Why is my ideal weight different on other sites?
Robinson, Miller, Devine, and Hammond formulas differ. We show Devine plus a BMI band so you are not locked to one equation.
How fast should I move toward a goal weight?
Many adults do well near ~0.25–0.5% of body weight per week. Faster loss can increase rebound and muscle loss risk.
