Pattern and Grading


A pattern is created to produce prototypes or complete production runs. It is used throughout the production process. Patterns are the template of style and measurement. They communicate all necessary information to create perfect garments. Pattern makers have been called the architects of the fashion industry. Just as an architect creates blueprints used to construct sturdy buildings, pattern makers create patterns that are passed off to cutters and sample makers that are then used to create well-constructed garments. Without blueprints contractors would have no way of knowing where to begin and where to end. The original design intended for the building could end up being entirely lost and the building itself could risk being deemed unsafe or even worse… collapse. Without patterns the original design will be lost, and garments will be structurally unsound, ill-fitting, and ultimately unsellable.

What we'll need...

Information we’ll need to get started…

To communicate properly with our pattern maker the designer should be prepared with the following:

Garment patterns are incredibly important in cut and sew manufacturing.

  • how the finished garment should look
  • design, shape, fit, measurements and placement of all details for each garment

Our pattern maker works with this information, along with front and back sketches, technical flats, and spec sheets. All details from width of pant leg, spacing between pleats, special linings, specific types of seams, etc. are needed to expedite the completion of each pattern and garment/product.

How Does It Work?

Our pattern makers have years of experience specializing in production patterns to avoid fit issues. Creating a precise pattern is very important in cut & sew manufacturing. The process begins by draping on a form or drafting from a basic sloper flat on a pattern drafting table. From this step several rounds of adjustments are made. We repeatedly measure, mark, re-measure and re-mark until all fit needs and requirements are met and all design/style lines are created. From the initial paper pattern, muslin is cut and sewn into the garment used in the first fitting.

Based on the designer’s feedback in regards to the garment/product shown in the first fitting, our pattern maker will then revisit the original pattern and make the adjustments necessary to perfect the pattern. From this second pattern a second fitting garment/product is cut and sewn and another fitting is conducted. Again the designer gives feedback and from this feedback final adjustments are made to the pattern. Now, you’re ready to begin your Salesman Samples.

How does it work?


Patterns initially are made in only one size. In order to produce clothing that fits various body types and sizes, the pattern pieces must be increased or decreased geometrically to create a complete range of sizes. The process of re-sizing the initial pattern is called “grading.” Each company determines its own grade specifications for each size, and size specifications vary slightly from manufacturer to manufacturer. 

There are no standard sample sizes in the garment or pattern industry. Each manufacturer sets its own base pattern measurements and grades patterns based on a specific customer base. Grades can differ between industries, companies, and even different product lines. This is why one size 8 can be different from another size 8 (i.e., different base pattern measurements) and why the difference between a size 8 and 10 can vary between two different companies.

Grading Patterns

Grading a cut and sew pattern allows the producer to create different sizes of the same garment. Grades typically decrease or increase by an inch from size 0 to size 10; after that, from sizes 12 to 16, a decrease or increase of two inches between each size is customary. A “standard” industry grade, from Small to X-Large, is two-inch difference in circumference, with a half-inch length difference from one size to the next.

It’s important to remember that grading only makes a shape larger or smaller and isn’t intended to change a shape. Grading is also important because it isn’t enough to merely make everything equally larger or smaller. Instead, you must take into account proportional sizes of different body parts. One person’s waist can be vastly different from another person’s waist — but you won’t see anywhere near the same size variation in arm circumference.
