Sizing documents for smaller screens

[ponderoni]

I recently got my first smartphone, an HTC One V.
It seems like a great little workhorse, but has some issues - mostly due to size.

How do I read long, wide documents without having to scroll like crazy (and go blind in the process)? Some websites have a "Read" option that allows this.
Is there an app I can download to get the same result with (MS Word and other) documents ? If it worked with PDF, that would be even better.
