Body Type X Calculator #1
The formulas used below are derived from the body type X Standard Measurement Chart provided in the drafting book Patternmaking for Fashion Design Fifth Edition (2014) by Helen Joseph-Armstrong. This calculator provides a fairly robust set of measurements for drafting, completely driven by a single bust measurement.
If you add the Bust Front and Bust Back calculated values, they will be 1.25" (3.2 cm) greater than the Target Bust Size entered. This is not an error and is true to the values in the book. 🤷
The original source data was optimized for a bust range of 34" to 42.5" (86 cm to 108 cm). 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.
The measurement names have been updated to correspond directly with the PatternMaker Pro Measurement Guide to make them easier to locate and verify. There are a few exceptions that are not on the guide:
- Bust Depth: Measure from the shoulder tip to the bust apex.
- Waist to Ankle: Measure from the side waist point to the ankle.
- Mid-Thigh: Measure around the thigh midway between the crotch and the knee.
- Cap Height: This is not measured, it is calculated based on size. It is used for sleeve drafting.
- Imperial (Inches)
- Metric (cm)
