How much do the WWE edit the weights/heights of superstars?

I know that for example Glen Jacobs is only 6"7 - 6"9 and yet was listed as 7 foot, Mason Ryan weighs about 270lbs and is listed as 313lbs, I mean with the sort of average sized wrestlers. For example the Miz, is he lighter or shorter than listed? Santino Marella? Christian? etc, if so by how much?
