Footwear Pattern Making and Grading Calculations Based on International Standard of Measurements

Abstract: Footwear pattern making and grading are fundamental processes in footwear design, critical for creating shoes that are well-fitting, balanced, and aesthetically appealing. Key considerations in pattern making include accurately calculating essential measuring parameters of the last to ensure perfect fit and balance. Additionally, grading is vital for developing different size ranges from the master pattern. This research paper investigates the calculations of essential measuring points of footwear based on foot anatomy and discusses longitudinal and transverse grading factors. By exploring calculations involved in pattern making and grading according to international measurement standards, the paper aims to determine the ideal calculations and grading parameters for various footwear styles. The study examines footwear measuring terminologies and derives standard formulas by analyzing diverse techniques and standards, providing insights into best practices for footwear designers and pattern developers to achieve consistency and quality in their products.
