How many pages - How many words?
A good question.
It depends on who you are writing for. You may have a set number of words. You may have to sort out your own!
As a guideine:
For a university assignment, the assignment will tell you how many words minimum.
Unless otherwise requested, when writing essays keep them to a limit of about 700 - 1400 words. That’s about one to two typed pages of A4 paper, single spaced with paragraphs. (Thats using 12pt font such as Arial or Calibri, with margins in Word set to narrow).
As a guide:
In general for many courses: 700 -1400 words.
Unless otherwise stated, a really good story could be five to six pages.
When writing a really good long story to publish, think 100 to 200 pages. (That's about 70,000 to 140,000 words in 12pt font such as Arial or Calibri, with margins in Word set to narrow).
There are a lot of variations in between and no set rules apply unless you are writing a book for a publisher, or your assignment calls for a set number - (minimum or maximum) - of words.
