The math
(40.0mm / 36.5mm) × 100 = 109.7%
Based on 175cm human baseline, eye-level measurement (160cm).
Scale baselines
- Source eye level 33.3mm Eye
- Target eye level 40.0mm Eye
- Scale factor 109.7%
When you need this
You need this when bringing older or smaller 1:48 models into a modern 40mm collection. At only 10% difference, these scales can mix on the same table without looking wrong. Keep bases consistent and paint styles matched.
Source: 1:48
1:48 is the quarter-scale / aircraft and vehicle standard. Common for vehicles and aircraft. Figures in this scale are smaller than typical wargaming miniatures and are usually accessories to a vehicle kit rather than standalone game pieces. Common systems: US O-gauge trains, Bandai Star Wars kits, Aircraft model kits.
Note: 1:48 figures are often molded in soft vinyl rather than hard plastic. If 3D printing replacements, increase wall thickness for durability.
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 109.7%. FDM works well at 40mm for monsters and vehicles with a 0.4mm nozzle.
