Smallest and Largest text on the web

Ever wonder what's the smallest possible text size on the web?

The smallest possible text size is 1px, you can make them 0.0000001px but
it doesn't make such different on the browser appearance.

The largest text that still can be readable after reducing the text size or zooming out (IE7) page is in the region of 60000px.
There is some strange behavior with the largest text as sometime when it gets too large it become small again.

To test this experiment you can use Firefox and hold Ctrl key while keep pressing (-) or (+) to zoom in and out.
