How do i set the number of characters per line of output?

If I had a file (file.txt) which is just an essay or whatever, and i wanted to use that file in my output, but only wanted 50 characters per line of output, how would i do that?

I don't need to know how to import the file, just how to set the number of characters per line of output.
