How to Use Scale Calculator

  1. Enter original model dimension (X, Y, or Z in mm).
  2. Enter target desired dimension or select standard scale preset (e.g. 28mm heroic, 1:100 architectural, 1:12 dollhouse).
  3. Instantly obtain exact scaling percentage to enter into your 3D slicing software.

What is the 3D Model Scale Calculator?

A proportional dimension converter that translates between real-world architectural/miniature scales and slicer percentage multipliers.

Formula Used

• Slicer Scale (%) = (Target Size (mm) / Original Size (mm)) × 100 • Volume Scale Multiplier = (Scale % / 100)³

Real-World Example

Scaling a 1:1 life-size sword (1,000mm) down to 1:6 action figure scale (166.6mm): • Scale % = (166.6 / 1000) × 100 = 16.66% • Material mass drops to (0.1666)³ = 0.46% of original life-size weight.

Accuracy and Limitations

Be mindful that scaling down models by large factors reduces thin wall features below printable nozzle limits.

Who It Is For

Miniature wargaming hobbyists (Warhammer, D&D), architectural model makers, and action figure customizers.

Frequently Asked Questions

How do you calculate 3D model scale percentage?
Scale Percentage = (Target Dimension in mm / Original Dimension in mm) × 100. For example, scaling a 150mm model to 90mm requires entering 60% in your slicer.
