I was referring more to the type of font they used rather than the size of the font.
Standard Pica or other typewriter style font's just don't show up well on my screen.
Besides, I may be stupid, but not blind! (to paraphrase a bit),
Hit the Ctrl and + keys on your keyboard at the same time and any webpage font will enlarge. Each time you do it it will get larger. Unfortunately this doesn't seem to affect photos or some other parts of the page.
Don't know what the size limit is, never tried.
Same goes for smaller, just hit the Ctrl and - keys.
