I don't understand how there could be a more direct measurement, unless you're looking for an equation.

According to the definition from wolfram, an affine transformation is one that "preserves collinearity ... and ratios of distances."
Thus if you're scaling everything, the distance will scale with the lines as well. Thus new h = old h * scale amount. Otherwise the h will stay the same.

Hope this helps,
