Pattern grading

Pattern grading is the scaling of a pattern to a different size by implementing important points of the pattern using an algorithm in the clothing and footwear industry.

History.

Early sewing patterns were made to fit a specific individual. This one size was created through various measurements of the individual's body. Often these patterns were then cut out of cardboard. No directions for the orientation of the pattern piece on the fabric or identification of what part of the garment the piece represented were present on these patterns. Resizing or grading the pattern was a complicated task for even the most skilled seamstress. It was not until the 1850s that sewing patterns were made available to a slightly larger, affluent public. American women could obtain a paper pattern made for them through their dressmaker or could purchase a pattern through a women's journal. The advent of large scale production graded, practical and easier to use sewing patterns can be traced to 1867. Mass-produced patterns printed on tissue paper were the product Ebenezer Butterick. Each pattern sold was one size per package but available for purchase in a variety of sizes. It was not until the 1970s, due to lagging sales, that multi-size graded patterns became available.,^{[1] [2]}
