1:72 to 40mm Miniature Scale for 3D Printing
Convert 3D printed tabletop miniatures from 1:72 to 40mm. This STL scale calculator is designed for Warhammer, D&D, and tabletop gaming miniatures.

Uniform scale (XYZ locked)
The math
(40.0mm / 24.3mm) × 100 = 164.6%
Based on 175cm human baseline, eye-level measurement (160cm).
Scale baselines
- Source eye level 22.2mm Eye
- Target eye level 40.0mm Eye
- Scale factor 164.6%
When you need this
You need this when bringing older or smaller 1:72 models into a modern 40mm collection. This is a big upscale. Models will look like different species next to each other unless you apply the conversion to the entire unit or army.
Source: 1:72
1:72 is the small-scale military / budget army builds. Popular for large army builds on a budget. Figures are roughly 20-22mm to the eyes. Entire platoons fit in a shoebox, making this scale ideal for travel and storage. Common systems: Airfix, Revell, Zvezda.
Note: 1:72 scale creep exists too: modern sculpts are often closer to 1:64. Check base-to-eye measurements before committing to a print.
Target: 40mm
40mm is used by Star Wars: Shatterpoint, Inquisitor (GW specialist game), Heroic 40mm custom scenes. Used for centerpiece models, display dioramas, or games where individual heroes need to stand out. A 40mm figure has roughly twice the surface area of a 28mm model.
Note: 40mm bases can destabilize on uneven terrain. Consider magnetizing or weighting the base.
Print notes
Set your slicer to 164.6%. FDM works well at 40mm for monsters and vehicles with a 0.4mm nozzle.
