Miniature scale converter & STL resize

Going from a 32 mm sculpt to a 54 mm display piece — or 1:56 to 1:48? Set the two heights and get the exact resize % to type into your slicer, plus the new dimensions.

Pick a preset or type a height. Scale = target ÷ current.

How miniature scale works

Tabletop "mm" scales quote the rough height of a standing human figure — 28 mm heroic prints close to 32 mm tall, 32 mm a touch more, 54 mm and 75 mm are display sizes. Ratio scales (1:56, 1:48, 1:35) come from vehicle modelling; we convert them assuming a ~1.8 m human.

Scale % = target height ÷ current height × 100.
Scaling is uniform — width, depth and height all change by the same factor, so volume changes by the cube of it (2× taller ≈ 8× the resin).
Bases and slot tabs scale too — check them after resizing.
