Estimate an ideal weight range from height using common reference formulas.
Quick planning, rough comparisons, and checking whether your assumptions are in the right range before you rely on final quotes or advice.
Review the assumptions below, then compare with related calculators if your decision depends on rates, eligibility, or provider-specific rules.
How this calculator works
- This version uses a Devine-style reference formula.
- Height over five feet adds a fixed amount per inch.
- The result is a rule-of-thumb planning target, not a diagnosis.
Worked example
At around 170 cm, the reference range usually lands in the mid-60 kg zone.
Important assumptions
- Reference formulas are simplified and not body-composition aware.
- Frame size, muscle mass, and health history can shift a suitable target.
- Use this as a planning estimate rather than a strict goal.
Methodology and review
Shared calculator template reviewed for formula clarity and on-page transparency.
Editorial review focuses on practical accuracy, assumptions, and user-facing clarity.

How this calculation is produced
- This tool uses a published formula-based estimate from the health and nutrition category rather than an individualized clinical assessment.
- Results are calculated directly from the inputs you provide, so the output depends on activity level, body measurements, and the formula assumptions used.
- The calculation is intended for education and planning, then should be checked against real progress or professional advice if the decision is health-related.
What to verify before relying on it
- Compare the result with medical or nutrition guidance if the output affects treatment, diet planning, or health goals.
- Check whether your selected activity level and units are realistic before relying on the final number.
- Validate high-stakes decisions with a clinician, dietitian, or a second trusted calculator.
When this tool is useful
- Use this before setting diet, hydration, or body-composition targets.
- Use it for quick screening and planning, not as a medical diagnosis.
- Use it again when weight, training level, or daily routine changes.
How to read the result
- Treat the primary result as a starting estimate rather than an exact prescription.
- Compare the result with your real-world trend over a few weeks before making large changes.
- If the result influences health decisions, review it alongside body composition, symptoms, and professional advice.
Common mistakes
- Assuming one formula captures muscle mass, medical history, and lifestyle perfectly.
- Changing calories, hydration, or protein targets too aggressively from one estimate alone.
- Ignoring that activity level selections are often the weakest assumption in health formulas.
Good next steps
- Pair this result with a related health calculator to cross-check the plan.
- Track your actual progress and adjust based on outcomes, not just the formula.
- Use a clinician or dietitian when the result affects a medical or high-stakes goal.
