MODULE 1 • What is Pattern Grading?

Step Description
1 Pattern Grading is the systematic method of proportionally increasing and decreasing the size of a garment pattern, while maintaining the designer’s style and fit.
2 The American Society of Testing and Materials defines Grading as a method of creating multiple sizes from a base or sample size, using a grade rule.
3 When shopping for clothes, we have all experienced the concept of pattern grading. In search of the perfect fit, you may try on several sizes of the same garment. If the first were too big or too small, then you would try a size smaller or larger, in hopes of finding a good fit. In this lesson, we will grade a basic bodice, sleeve, skirt and pant pattern.
