Pattern grading should not be confused with pattern alterations. Alterations are the process of making a pattern fit the nuances of an individual body. Whereas, grading is the process of creating a range of new sizes, or a size run.
Grading may simply be defined as the increasing or decreasing of a pattern according to a set of corresponding body measurements. The secret to professional grading is to understand where the body requires these changes.
Patterns can be graded using: the cut and spread method, pattern shifting or with computer grading.
