Scale Dimensions Calculator

Useful for converting between full size dimensions (in English or Metric units) and scale size dimensions (in English or Metric) in both directions.

You may enter the scale (in inches per foot), or enter a ratio. Full size dimensions may be entered in either English or metric dimensions. The scale dimension is given in both inches and millimetres.

A reverse direction calculator for entering a scale size to get the corresponding full size dimension is at the botton of this page.
