1:100 to 28mm Miniature Scale for 3D Printing
Convert 3D printed tabletop miniatures from 1:100 to 28mm. This STL scale calculator is designed for Warhammer, D&D, and tabletop gaming miniatures.
Slicer Setting
Uniform scale (XYZ locked)
The math
(28.0mm / 17.5mm) × 100 = 160.0%
Based on 175cm human baseline, eye-level measurement (160cm).
Scale baselines
- Source eye level 16.0mm Eye
- Target eye level 28.0mm Eye
- Scale factor 160.0%
When you need this
You need this when bringing older or smaller 1:100 models into a modern 28mm 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: 1:100
1:100 is the micro-armor / mass-battle standard. Used for large tank battles and regiment-level games where table space is limited. Figures are approximately 15mm tall. A single A4 sheet of terrain can represent an entire battlefield. Common systems: Flames of War, Team Yankee, 15mm wargaming.
Note: 1:100 and 15mm are often used interchangeably, but 15mm can mean 15mm to the eyes or 15mm total height. Our calculator uses eye-level baselines to eliminate ambiguity.
Target: 28mm
28mm is used by Dungeons & Dragons, Pathfinder, Oldhammer. 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.
Note: Older sculpts may be closer to 25mm true-scale. Always check the sculptor's baseline before scaling.
Print notes
Set your slicer to 160.0%. FDM rarely needs compensation; slight over-extrusion usually cancels any cooling shrinkage.
