how much do you usually charge for editing an article?its about 300 pages long.thanks. Answer1:A million years ago, when I was in law school, I charged $1.50 per page to edit the grammar of sentences without revising the structure of the papers. It really depends on the quality of your writing. To edit an article so that it is good quality, the editor needs to understand the subject matter and may need to revise the structure of the article. I was hired to edit a book written by an architect, and his writing was so poor that I didnt have a clue what he was trying to say. I had one Ph.D candidate bring me his thesis, and he told me that it wouldnt need much work. Well, it did. I gave it to him, and he came back and told me that he used to think he was a good writer, but after looking at my revisions, he realized that he was not.
