GRADING

Each manufacturer sets both their base pattern and grading measurements in order to meet the desired sizing for the target audience. Each pattern has a defined range of sizes for a single apparel style. Grading does not change the style or shape of a pattern but merely increase or decrease the size of it. Grading also reflects the fact that different sizes are proportionately different, not uniformly. 

​

Once the approved average is sized (typically size 8), the pattern will follow a set of "grade rules". These grade rules allow for the manufacturer to systemically increase or decrease the middle-sized pattern based on the desired size, essentially a size chart.
