# Nonuniform Scaling

In nonuniform scaling, the changes in the x- and y-axis units are not equal. Nonuniform scaling alters the aspect of a coordinate space. You can think of nonuniform scaling as either:

- a scaling by two different scaling factors (Sx and Sy) or
- a uniform scaling (S) and an additional aspect ratio (A).

The following matrix describes scaling by two different scaling factors:

Alternatively, this matrix represents nonuniform scaling accomplished by applying a uniform x- and y-axis scaling factor and an aspect ratio:
