Ideal Weight Calculator
Estimate healthy-weight range from BMI and compare current weight against Devine ideal body weight reference.
Above reference target. Use trend-based planning rather than aggressive short-term cuts.
Current Weight vs Target Reference
This table compares your current weight against the selected ideal-weight reference (Devine IBW).
| RANGE | CATEGORY |
|---|---|
| 0-90 | Well Below Target Current weight is far below reference target. Clinical context matters for interpretation. |
| 90-100 | Near Target (Low) Near the selected target and below or at reference value. |
| 100-110 | Near Target (High) Close to selected target range and often manageable with minor adjustments. |
| 110-120 | Above Target Above reference target. Use trend-based planning rather than aggressive short-term cuts. |
| 120-130 | High Substantially above target reference. Structured deficit planning can help. |
| 130+ | Very High Well above reference target. Consider medical guidance for individualized planning. |
What This Ideal Weight Calculator Includes
This page shows two common reference outputs:
- Healthy BMI range for your height (18.5 to 24.9)
- Devine ideal body weight (IBW) reference from height and sex
Why There Is No Single Perfect Number
"Ideal" weight is a reference concept, not a diagnosis. Body composition, frame size, muscle mass, and health markers can shift what is realistic and useful for a given person.
Use these outputs as planning anchors, then monitor trend quality using waist, performance, bloodwork, and adherence.
How To Use This With Other Tools
Pair this with the Weight Loss Calculator to estimate timeline to a target and the BMI Calculator for direct category screening.
To plan calories around that target, estimate maintenance in the TDEE Calculator and set intake in the Calorie Deficit Calculator.
For medication-dosing contexts where adjusted weight is used, see the Adjusted Body Weight Calculator.
