Create a Formula for the Width of the Armhole Cuffs

How to calculate the width of the armhole cuffs:

The width of the armhole cuffs are calculated doubling the sum of length of the following armhole segments:


[Width of the Armhole Cuff] = 2*(x+y)


a = ([ Body Width at the Waistband ]-[ Shoulder Width ])/2
b = [ Height of the Armhole Narrowing ]
x = √((([ Body Width at the Waistband ]-[ Shoulder Width ])/2)²+[ Height of the Armhole Narrowing ]²)

Formula for the width of the armhole cuffs:

The final formula for the width of the armhole cuffs results replacing the calculation of x and y in the original formula.
[Width of the armhole cuffs] = 2*(√((([Body Width at the Waistband]-[Shoulder Width])/2)²+[Height of the Armhole Narrowing]²)+[Armhole Drop]–[Height of the Armhole Narrowing])
