I'm not sure this is true, Bruce. Consider Times New Roman, which is a slightly condensed font (because it was designed for narrow newspaper columns). I think condensing a face gives it a more vertical appearance and therefore enhances the illlusion of larger size. On the other hand, extended faces always look smaller to me.

Yes, letterforms are different heights (in virtually all serif fonts and in a great many sans-serif fonts, too). The caps, for example, may reach higher than the lowercase ascenders--or vice versa. The top of an uppercase A or C is always a bit higher than the top of the corresponding uppercase B (to compensate for a well-understood optical illusion). For the same reason, in the lowercase alphabet, the bowl of the c, for example, extends both above the x-height and below the baseline. The descender of the y may not extend as far down as that of the p (or vice versa); the bowl of the g may be shorter still. Etc.

It could be that you are correct about digital faces now having built-in top and bottom bearings, although I have not heard of this practice. But given that the page designer can specify negative leading if desired, I'm not sure what the practical effect would be.
