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.
