Grading is the process of scaling a pattern up or down to create different sizes while maintaining the proportions and design details of the original pattern. This is essential in the garment manufacturing process to ensure that a clothing item is available in various sizes to accommodate different body shapes and preferences.

During grading, each part of the pattern is systematically adjusted to meet the specifications of different sizes, while still adhering to the original design’s integrity. This allows manufacturers to produce a range of sizes based on a single master pattern, streamlining the production process and ensuring consistency across the size spectrum. Grading is a critical step in achieving a well-fitting and aesthetically pleasing garment for a diverse audience.
