Scale Factor Dilation Formula

The following formula is used to calculate the scale factor dilation of an image or shape.

SF = X2/X1 = Y2/Y1

  • Where SF is the scale factor dilation
  • X2 and Y2 are the change in X and Y of the final image
  • X1 and Y1 are the change in X and Y of the original image

Scale Factor Dilation Definition

A scale factor dilation is a ratio of the length or area of an image before and after it has been enlarged or shrunk.

Scale Factor Dilation Example

How to calculate a scale factor dilation?

  1. First, determine the change in X and Y of the original image.

    Measure the change in X and Y of a single length of the original image.

  2. Next, determine the change in X and Y of the modified image.

    Measure the change in X and Y of the same length on the modified image.

  3. Finally, calculate the scale factor dilation.

    Calculate the total scale factor dilation using the equation above.
