- Chest-to-knee desired length — Required
- Waist tie overlap — Required
Apron size
Enter the measurements above to calculate apron size.
How the calculation works
V12 calculation: minimumApronBibWidth=chestWidth; apronBodyLength=torsoLength; minimumWaistTieTotal=waistCircumference+wrapOverlap. This is the implementation specification for this calculator.
Worked example
Example: Front chest width = 60 cm; Waist circumference = 86 cm; Chest-to-knee desired length = 62 cm; Waist tie overlap = 50 cm. Result: Minimum Waist Tie Total = 136 cm; Apron Body Length = 62 cm; Minimum Apron Bib Width = 60 cm.

Direct measurement/geometry calculation. No external reference is required for the arithmetic itself; the result is derived only from the user-entered measurements and the formula stored in calculationLogicJson.
