		<description>You could also use MySQL&#039;s `text` data type, and not need to worry about field-size.</description>

		<description>Interesting, but I would be interested to see more statistical analysis of the URLs. i.e. smallest, largest, and 95%/98%/99.5% confidence for length of URL. I see that the raw mean helps with your requirement, but it doesn&#039;t answer questions like &quot;How long should I make a database field to store a URL?&quot;. 

If we knew that (as an example), 98% of URLs will fit into a VARCHAR(100) field, and 99.5% will fit into VARCHAR(200) then it would make it easier to make these choices. Perhaps you would you like to contribute such knowledge to the benefit of all? :-)
