Web pages don't have to be set to a particular text size. Usually, the problem is if you set the text size with CSS. One size does not fit all. Or if you use funky formatting, the text will be cut off if the user's setting is larger than the web designer expected.

Ideally, you should let the user's browser settings determine the text size. You can sort of test this in IE by using the "accessibility" options. See what your page looks like with ignore font sizes checked. People do surf with their browsers set that way, especially if they are visually handicapped or just are over 40 years old. And Firefox makes it very easy to see what your site looks like with different font sizes.

Making a web page that is accessible to all does limit what you can do with layouts, etc. I've noticed many sites these days now offer several sizes - so the page is readable on a variety of systems, and they can still use fancy layouts.

But in the case of this site...the layout is really pretty simple. It would be pretty easy to get a similar look - without having the text cut off if the font size is wrong.
