Each word processor counts words differently. You might think that a computer—a machine designed to count things and perform complicated calculations—should be able to count words, but it all depends on how its program defines what a "word" is. See https://anycount.com/WordCountBlog/why-are-there-differences-in-word-counts/ for more information, if you're interested.
But you're probably here because this site told you that your abstract has exceeded the word count, and you want to know what to do. Here are some things to try if your word processor says that your abstract is < 650 words in length, but this site has told you otherwise:
- Remove spaces before and/or after dashes (e.g., abc—def, not abc — def).
- Make sure that there is only one space after a period. Sometimes a double space can result in a hidden character that can be counted as a word.
- Remove empty paragraphs that you may have inserted for formatting purposes.
- Don't include the title of your abstract in the body of the abstract. Use the "Title" field for that purpose.
