How It Works
Pattern scaling multiplies every dimension by the same factor. A 110% scale increases each measurement by 10%, but the total area increases by 21% (1.1 x 1.1 = 1.21). For simple size adjustments, scaling works well. For multi-size grading, professional pattern grading is preferred since different body areas grow at different rates.
