Ideal Weight Guide

How It Works

This calculator estimates your ideal body weight using standard medical formulas. It creates a baseline for healthy weight goals based on your height and gender.

Men (Devine)
50 + 2.3 × (Height in inches – 60)
Women (Devine)
45.5 + 2.3 × (Height in inches – 60)
Base: 5ft (60 inches)
Example Calculation

Calculating for a height of 5’8″ (68 inches):

Height
5’8″ (68″)
Difference
8 inches > 5′
Male Result 68.4 kg
Female Result 63.9 kg
Benefits & Use Cases

Use this as a general guideline to check if your current weight falls within a medically accepted norm.

Goal Setting

Useful for medical professionals and fitness trainers to determine dosage or nutrition plans.

Frequently Asked Questions
Q1: Is ideal weight the same for everyone?

No. It depends heavily on gender, height, and age. Body frame size and muscle composition also play a major role.

Q2: Which formula is used?

This calculator primarily uses the Devine Formula (1974), which is the most widely used formula for medical dosages and ideal body weight.

Q3: Can athletes rely on this?

No. Athletes often have high muscle mass, making them weigh more than the “ideal” formula suggests, despite being very healthy.

Q4: Should I aim for this exact number?

No. Treat this as a reference point. Aim for a healthy weight range (using BMI) rather than a single fixed number.
