Common sense is 80 columns for prose, because anything longer makes it difficult to easily read from one line to the next.

Code, however, (a) does not fit into dense paragraphs, and (b) often comes with heavy indentation. I used to try and fit it into eighty columns, and ended up with the code more difficult to read, as a result. I'd say 132 columns is a reasonable optimum on this scale.

Common sense for prose is 60-70 columns.

If your code marches off the right of your screen then you're doing it wrong.

I don't have difficulty reading prose which is significantly wider than 80 characters, but I'm used to reading solid prose on a 1680x1050 screen with small fonts.
