I think that will be the most common answer to that question.

Now the question about if that is enough, well that depends on how big your sidebar is, which would dictate how much text showed on the content side.

Another thing i would say is never go bigger then 100k, if the page size says more then that get rid of it. A quick check of my wp sites that are thought well of to google shows index's with 25-40k page size. So that much?..
