On this page you can use the calculator to work out sizes for all the scales listed below or work back to see how large an item would be in real life based on its scale size. Click on any of the input fields and enter a value then click on the calculate button. Your value will be converted and the results shown in the other fields. Results are rounded to 3 decimal places.
The scales used here are based on the values found on the Wikipedia page for modelling scales. If you would like another scale adding to the conversion table please let me know via the Contact Us page.
