Convert between common miniature scales or use the model’s actual measured height. The result is the uniform percentage to enter in your slicer.

A 28mm figure becomes 32mm when all three axes are scaled uniformly.

This method is usually safer when the sculptor’s advertised scale and the actual file disagree.

Scaling an STL also scales an attached base. Separate it first when the game requires a specific footprint.

BEFORE YOU PRINT FIFTY OF THEM
Scale labels are starting points.
“28mm” and “32mm” are not universal physical standards. One sculptor may measure to the eyes, another to the top of the head, and a third may use the label to describe a compatible game system rather than a literal height.
For the most dependable result, measure a reference miniature you already own, measure the imported STL in your slicer, and use the height-to-height calculator. Print one test model before committing to a unit.

MINIATURE SCALE FAQ
The confusing parts, clarified.
What percentage scales a 28mm miniature to 32mm?
Use 114.3% as the mathematical starting point. Because heroic proportions and measurement conventions vary, verify the result against a model you already like before printing an army.
What percentage scales 32mm down to 28mm?
Use 87.5%. Keep uniform scaling locked so the X, Y, and Z axes change together.
Should miniature height be measured to the eyes or top of the head?
Both conventions are used. Historical wargaming scales are often measured to eye level, while many sculptors describe the full figure height. Measure the actual file when consistency matters.
Does scaling an STL change weapon and base sizes?
Yes. Uniform scaling changes every part of the file, including weapons, integral bases, sockets, and support geometry. Separate the base first if it must remain a legal game size.
Which miniature scale is closest to 1:56?
28mm is commonly associated with 1:56, but figure height conventions and heroic proportions vary. Treat the ratio as a useful comparison rather than a universal conversion.
How do I print the miniature scale ruler at actual size?
Choose the print reference button, set page scaling to 100%, and disable Fit to Page. Measure the 50mm calibration bar before using the silhouettes or base circles as physical references.
