HOW BIG IS MY MODEL?

 

Models and scale models always have a scale.

A scale is used to ascertain the size of a model based on the size of the real object. You simply need to multiply the size of the real object by the scale.

For example, the model of a boat which measures 100' from front to back will measure:

100' X 1/200 = 0.5' (6 inches) on a 1:200 scale 

100' x 1/350 = 0.28' (3" 3/8) on a 1:350 scale
100' x 1/700 = 0.14' (1" 5/8) on a 1:700 scale

 

To give you an idea, here are the sizes of some models.

The most common scales are shown in red.
