When calculating shrinkage, you need to factor in the tolerance along with the shrinkage. Below table shows an example for the size large of style 5051.
Calculate the tolerance range for both the body length and chest specs. Calculate the 5% - 7% range of the shrinkage combined with the tolerances.
*Note: Some fabrics, specifically organic cotton, can have slightly higher amounts of shrinkage due to the nature of the organic threads. They can have 8% to even 9% shrinkage.
