Understanding Ideal Weight

Multiple Formulas

We use 7 scientific formulas (Robinson, Devine, Miller, Hamwi, etc.) and average them for best accuracy.

Healthy Range

Your ideal weight is a range, not a single number. Individual variation in muscle mass and frame affects optimal weight.

Gradual Progress

Aim for 0.5-1kg (1-2lbs) per week weight change. Sustainable progress requires patience and consistency.

How the Ideal Weight Calculator Works

Understanding evidence-based weight range calculations

Multiple Formula Approach

Our calculator uses 4 validated formulas (Robinson, Miller, Devine, Hamwi) and provides a range rather than single number. Different body frames and builds fall at different points within healthy ranges.

Ideal weight is a range, not a number. These formulas account for height, gender, and frame size to estimate healthy weight ranges validated by decades of health outcome research.

Formula Accuracy:

  • Robinson (1983): Modern standard formula
  • Miller (1983): Similar to Robinson
  • Devine (1974): Medical dosing standard
  • Hamwi (1964): Quick estimation method

Why Target Ranges Matter

Health outcomes improve within ranges, not at specific numbers. Someone at the low end can be just as healthy as someone at high end, depending on muscle mass and body composition.

Where You Should Be:

  • Small frame: Lower end of range
  • Medium frame: Middle of range
  • Large frame: Upper end of range
  • Muscular build: May exceed range healthily

When to Use the Ideal Weight Calculator

Setting realistic and healthy weight goals

Starting Weight Loss Journey

Before dieting, set evidence-based targets. Unrealistic goals lead to crash diets and rebound weight gain.

Doctor Consultations

Use before medical appointments to discuss healthy weight ranges with your healthcare provider.

Reality Check

If your goal weight is far outside healthy ranges, reassess expectations. Focus on health, not arbitrary numbers.

Setting Healthy Weight Goals

Realistic Goal Setting:

  • • Target middle of your healthy weight range
  • • Consider your frame size and build
  • • Factor in muscle mass if you lift weights
  • • Aim for 0.5-1% bodyweight loss per week
  • • Focus on body composition, not just scale
  • • Adjust goals based on how you feel

Unrealistic Goal Traps:

  • • Targeting weight from high school/college
  • • Using celebrity or model weights as targets
  • • Ignoring your natural frame size
  • • Setting timeline-based crash diet goals
  • • Not accounting for muscle gained from training
  • • Obsessing over single "perfect" number
