The Scale Lab

Anatomical scaling calculator with Square-Cube Law physics

Parameters

lbs

Supports decimals (0.5), fractions (1/12), and percentages (500%)

Calculation Assumptions

Output dimensions are derived from NASA Man-Systems Integration Standards (STD-3000) and average female anthropometric data:

  • Head Height ≈ 13.3% of Height
  • Hip Height ≈ 53% of Height
  • Mouth Width ≈ 3.5% of Height
  • Hand Length ≈ 10.5% of Height
  • Foot Length ≈ 14.2% of Height
  • Mass scales with the Cube of the scale factor (mass ∝ scale³), assuming constant density.
