Enter the original size into the calculator to determine the scale size.

1/12 Scale Formula

The following formula is used to calculate the scale size for a 1/12 scale calculator.

SS = O / 12


  • SS is the scale size (inches, cm, etc.) O is the original size (inches, cm, etc.)

To calculate the scale size for a 1/12 scale calculator, divide the original size by 12. The result is the scale size.

What is a 1/12 Scale?

A 1/12 scale is a type of scale commonly used in models and miniatures, where one unit (such as an inch or a centimeter) on the model represents 12 units on the actual object. For example, if a model car is 1/12 scale and the actual car is 12 feet long, the model would be 1 foot long. This scale is particularly popular in dollhouses, where it allows for a high level of detail while still keeping the model a manageable size.

How to Calculate 1/12 Scale?

The following steps outline how to calculate the 1/12 Scale using the formula: SS = O / 12.

  1. First, determine the original size (O) in inches, cm, etc.
  2. Next, divide the original size (O) by 12 to calculate the scale size (SS).
  3. Finally, the scale size (SS) represents the 1/12 scale in inches, cm, etc.
  4. After inserting the variables and calculating the result, check your answer with the calculator above.
