Body Type Y Calculator #1

The formulas used below are derived from the body type Y Standard Body Measurement Chart provided in the drafting book Metric Pattern Cutting for Men's Wear Fifth Edition (2011) by Winifred Aldrich. This calculator provides a set of measurements for drafting, completely driven by a single chest measurement.

The reference book also includes garment length, which I have chosen to ignore. It is too dependent on the particular garment being drafted for this type of generalization, in my opinion.

The height range is 173 cm to 180 cm (5'8" to 5'11"). Included are adjustments for short or tall individuals. You can further refine the calculations with these changes.

The original source data was optimized for a chest range of 88 cm to 120 cm (34.5" to 47.25"). While this calculator will generate values outside of this range, please note that extreme sizes may require additional mock-up adjustments, as body proportions naturally shift outside standard grading brackets.

note

The measurement names have been updated to correspond directly with the PatternMaker Pro Measurement Guide to make them easier to locate and verify.
