Pants and shorts grading pattern is the technique used in turning a base size or sample size which is typically a size 6 into various sizes using a size specification sheet or grading increments. These increments are referred to as garment grading rules and each specific pants and shorts industry has different grading rules. This grading technique can be a manual pattern grading process or computer pattern grading using special computer aided design software.
Pants and shorts grading is an indispensable step that are frequently undertaken by designers and pants and shorts manufacturing firms because they are majorly required to mass produce a set of specific size patterns. Pants and shorts grading ensures that pants and shorts pattern sizing would be available to fit all body sizes. By having a variety of sizes for each pants and shorts, a designer would be able to fill out his minimum pants and shorts order cost effectively. Pants and shorts grading does not create shape, it only ensures that the sizes of the pants and shorts are increased or decreased while the pants and shorts retains its original size. In pants and shorts grading, the first size pattern is usually produced in a particular size usually a size 6 and then the pants and shorts are then resized, graded up and down. A graded up pants and shorts means to increase the size while a graded down pants and shorts means to reduce the size.
The purpose of pants and shorts grading is to evenly increase or decrease the size of a pants and shorts while retaining the shape, fit, balance and scale of style details of the pants and shorts.

Manual Pattern Grading
There are two ways of grading pants and shorts using the manual pattern grading; cut and spread method and the pattern shifting method. The cut and spread method involves cutting the pants and shorts and then spread the fabrics by a specified measurement to grade up or overlap the fabrics to grade down. While the pattern shifting method involves increasing the whole measurement of the pants and shorts by moving it around at an even measurement. After adjusting the measurement, the outline is then joined together around the sewing line in order to retain the shape of the pants and short.

This software allows the designer to indicate every component of a pants and shorts details and then modify each pants and shorts pattern individually until the ratio and desired measurement of the base pattern are in line with the preferred measurement wished to be adjusted. As soon as the pants and shorts pattern is uploaded or created into the computer aided design system, the system automatically begins the process of grading up or grading down the pants and shorts to the specified measurement.

iii. the grading can be done from anywhere and process can also be easily monitored by the customer
iv. the entire process can be easily modified and tailored within a short time frame without incurring any significant delay or cost
v. high accuracy is easily achieved
i. the computer aided system operator have to constantly train themselves to meet up with the various software updates
ii. it could be a herculean task finding a skilled operator to run the computer aided design system software
iii. it is a very expensive software to obtain
