Question: how many words is a report?
Answer: There's no set minimum or maximum, regardless of the type of report. If you'd like a guesstimate, just assume the audience will take around 10-20 minutes reading the report. And on average, your readers can read 1 double-spaced page or 250 words in a minute. In 10 minutes they would have read about 2,500-4,500 words.
