the average length of a script
Guidelines to Average Manuscript Lengths. Bear in mind that to say you have a manuscript of fifty pages, doesn't adequately convey its length. It depends on how many characters-per-inch (cpi) it was printed at. If printed at 10 cpi, there will be about 250 words per page, making the manuscript about 12,500 words; if printed at 12 cpi, there will be about 300 words per page, making the manuscript 15,000 words.
