Miniature Scale Size Calculator

Work out miniature scale size instantly with clear inputs, formula shown and shareable results.

About Miniature Scale Size Calculator

The scale denominator is the real height in millimetres divided by the miniature height, which converts a stated figure size into a proper ratio. Wargaming figures quote heights rather than ratios, so a 28 mm figure of a 1.8 m human is really about 1:64, not the 1:56 often assumed from eye level.

Formula

Scale ratio

denominator = real height in mm / miniature height in mm

Worked example

With the default values below, Miniature Scale Size Calculator returns Scale denominator of 64.3. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 5 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is the Miniature Scale Size figure worked out?

denominator = real height in mm / miniature height in mm. The scale denominator is the real height in millimetres divided by the miniature height, which converts a stated figure size into a proper ratio.

Why does this matter?

Wargaming figures quote heights rather than ratios, so a 28 mm figure of a 1.8 m human is really about 1:64, not the 1:56 often assumed from eye level.

What do I need to enter?

Enter miniature height, represented real height. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
