The math

(50.0mm / 28.0mm) × 100 = 178.6%

Based on 175cm human baseline, eye-level measurement (160cm).

Scale baselines

  • Source eye level 28.0mm Eye
  • Target eye level 45.7mm Eye
  • Scale factor 178.6%

When you need this

You need this when bringing older or smaller 28mm models into a modern 1:35 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: 28mm

28mm is the heroic fantasy and historical wargaming standard. The classic tabletop standard. Measures to the eyes (160cm on a 175cm human), not the top of the head. Helmets, top-knots, and ornate headgear often add 2-4mm of perceived height. Common systems: Dungeons & Dragons, Pathfinder, Oldhammer.

Note: Older sculpts may be closer to 25mm true-scale. Always check the sculptor's baseline before scaling.

Target: 1:35

1:35 is used by Tamiya, Trumpeter, MiniArt. A true ratio scale, not a 'gaming scale.' A 1:35 human is approximately 50mm tall to the top of the head and 45.7mm to the eyes. Vehicles and armor dominate this scale.

Note: 1:35 figures from different manufacturers can vary by plus or minus 2mm due to nationality and era differences in uniform and equipment.

Print notes

Set your slicer to 178.6%. 1:35 vehicles print beautifully on FDM at 0.2mm layers with a 0.4mm nozzle.

Reverse conversion

Going the other way? The reverse calculation might be useful.
