Ideal Weight Calculator
Compare four height-based reference equations. Their average is not a personal medical goal weight.
Guide
How to use the Ideal Weight Calculator
The Ideal Weight Calculator helps you make a quick estimate, compare scenarios, and understand the numbers behind the result. It is designed for fast planning, with enough context to make the answer useful instead of just a number.
- Enter current measurements as accurately as possible, using the unit system that fits you best.
- Read the equation, reference assumptions and limitations alongside the estimate.
- Adjust assumptions such as activity level, sex, age, or goal where the calculator supports them.
Method
How this calculator works
It compares four implemented height-based reference equations above a five-foot baseline. The average is arithmetic, not a medically established ideal. Heights below the model's baseline are unsupported instead of silently clamped.
This calculator is useful for comparing formula outputs and understanding why they differ, not selecting a goal weight.
Because assumptions matter, try a few values that represent optimistic, typical, and conservative cases.
Health calculators are screening and planning tools, not medical advice. They cannot replace a clinician's evaluation.
Example
Worked example
For the male formulas at 70 inches, the implemented outputs are 75.0, 73.0, 71.0 and 70.3 kg. Their arithmetic average is 72.3 kg. This is a comparison of equations, not a prescribed weight.
FAQ
Common questions
Is the average of four formulas my ideal weight?
No. Averaging reference equations does not create an individualized medical target. Body composition, health history and other factors are not assessed.
What happens below five feet?
These implemented formulas use a five-foot baseline. Below it, the tool shows no formula estimate rather than returning the same weight for every shorter height.
What information do I need for the Ideal Weight?
You usually need formula sex and adult height of at least 5 feet (152.4 cm). You can change the inputs and recalculate as many times as needed.
