How long should an abstract be following apa guidelines?

According to APA guidelines, an abstract should be between 150 and 250 words.

There are some exceptions, such as:

* Dissertations and theses may have longer abstracts (up to 350 words).

* Conference papers might have slightly shorter abstracts (around 100-150 words).

However, the general rule of thumb for most publications is to keep the abstract within the 150-250 word range.
