Create a Formula for the Front Collar Width

The front collar width is calculated as the sum of the lengths of the following segments:

As the lengths of the diagonal segments only are approximations to the lengths of the curves, they are multiplied additionally by a correction factor.

[Collar Width] = x*2*Correction factor+[Cast-off Width at Front Neck]

The value of the correction factor is experience-based and is 1.1.
[Collar Width] = x*2*1.1+[Cast-off Width at Front Neck]

  • Calculation of x :
     x is calculated according to the theorem of Pythagoras.

    x² = a²+b²
    x = √(a²+b²)
    a = [    Neck Drop at the Front]

    b = ([Neck Width]–[Cast-off Width at Front Neck])/2
    x = √([Neck Drop at the Front]²+(([Neck Width]–[Cast-off Width at Front Neck])/2)²)
  • Formula of the front collar width:
    The final formula of the front collar width results when replacing the calculation of x in the original formula.
    [Collar Width] = √([Neck Drop at the Front]²+(([Neck Width]–[Cast-off Width at Front Neck])/2)²)*2*1.1+[Cast-off Width at Front Neck]
