Description
Subtract positive bodyCircumference from nonnegative garmentCircumference for ease and divide by body times 100 for easePercent.
Garment and pattern calculations use measurements, allowances, fold conventions, and repeat positions. A local calculation is one pattern component; fabric behavior, fit, and manufacturing tolerances require separate assessment.
Subtract positive bodyCircumference from nonnegative garmentCircumference for ease and divide by body times 100 for easePercent.
When to use this tool
Use Garment Ease Measurement when you need a bounded pattern, spacing, or allowance component using consistent length units.
How to use the tool and how it works
- Enter bodyCircumference, garmentCircumference. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read ease, easePercent. Use the output convention below.

| garmentCircumference | Garment Circumference | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| ease | Ease | Required. Finite number. |
| easePercent | Ease Percent | Required. Finite number. |

}Limitations and assumptions
- Negative ease is allowed; stretch, measurement sites, material, comfort, and appropriate garment sizing are not assessed.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Check the complete pattern and test fit or material behavior before production.
