28mm to 15mm Conversion
Wargamers drop from 28mm to 15mm mainly for the table: the same battlefield footprint holds roughly four times the miniatures at 15mm, which is why mass-battle rulesets standardized on it. This conversion is also how terrain and building STLs get resized to serve both scales from one file instead of sculpting or modeling twice.
To convert a model dimension from 28mm (1:56) to 15mm (1:100), multiply it by 0.56 (56 ÷ 100). The result is a smaller model — every length, width, and height changes by the same factor.

Frequently Asked Questions
How do I convert 28mm to 15mm?
Multiply any 28mm model dimension by 0.56 to get the 15mm dimension. This works because 28mm is 1:56 and 15mm is 1:100, so the factor is 56 ÷ 100 = 0.56.
Is 15mm bigger or smaller than 28mm?
15mm models are smaller: the same subject is only 0.56× the size in each dimension compared to 28mm.
