Scale Bench

Miniature scale calculator & STL scale converter

Resize miniatures and STLs by percentage, compare common wargaming scales and convert modelling ratios. Choose a hobby profile when nearby suggestions should reflect fantasy, sci-fi, historical, naval or aircraft work.

Approximate scale comparisonNominal mm and ratios are different conventions, not universal equivalents.

With a 1800 mm reference, 25 mm is approximately 1:72.

Door height at 1:56: 37.5 mm

FIELD NOTESSmall details matter

Integral bases, magnet holes and sockets scale with the miniature. Weapon thickness and other small details change proportionally too.

Pre-supported resin files may need supports regenerated after a significant resize. Print one test miniature before resizing a complete army.

“28 mm” and “32 mm” are useful conventions, not guaranteed manufacturer standards. Heroic and realistic proportions can still look different at the same height.
