1:56 to 40mm Miniature Scale for 3D Printing
Convert 3D printed tabletop miniatures from 1:56 to 40mm. This STL scale calculator is designed for Warhammer, D&D, and tabletop gaming miniatures.

The math
(40.0mm / 31.3mm) × 100 = 128.0%
Based on 175cm human baseline, eye-level measurement (160cm).
Scale baselines
- Source eye level 28.6mm Eye
- Target eye level 40.0mm Eye
- Scale factor 128.0%
When you need this
You need this when bringing older or smaller 1:56 models into a modern 40mm collection. This upscale is noticeable but manageable. Most painters bridge the gap with basing detail, posture adjustments, or custom base rims.
Source: 1:56
1:56 is the wargaming vehicle companion scale. Often paired with 28mm infantry. Tanks and vehicles at 1:56 look correct next to 28mm figures because the vehicle scale accounts for ground clearance and hull height, not just eye level. Common systems: Bolt Action, Chain of Command, Flames of War (vehicle scale).
Note: Some manufacturers label 1:48 vehicles as 'compatible with 28mm.' They are slightly oversized. Stick to 1:56 for visual harmony.
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 128.0%. FDM works well at 40mm for monsters and vehicles with a 0.4mm nozzle.
