APA format is a standardized way of formatting academic papers and citing sources created by the American Psychological Association, most commonly used in psychology, education, nursing, and many social sciences.

What APA format is (in plain English)

APA format is both:

  • A paper format : how your document looks on the page.
  • A citation style : how you credit sources in the text and in the reference list.

The current version used in schools and journals is APA 7th edition.

Core paper layout (quick checklist)

Most instructors asking “Use APA format” mean they want something like this:

  • 1 inch margins on all sides.
  • Double-spaced text throughout (including title page, headings, and references).
  • Standard, readable font, often:
    • Times New Roman 12 pt, or
    • Arial 11 pt, Calibri 11 pt, Georgia 11 pt.
  • Page numbers in the header, usually top right on every page.
  • First line of every paragraph indented about 0.5 inches.
  • Left-aligned text (not justified).

These settings make the paper easy to read and consistent across assignments.

Main parts of an APA-style paper

A typical student paper in APA format usually includes:

  1. Title page
    • Paper title (bold, centered, in the upper half of the page).
    • Your name.
    • Your institution (and sometimes course, instructor, and date, depending on instructions).
    • All double-spaced.
  1. Body of the paper
    • Starts on a new page after the title page.
    • Organized with headings and subheadings (Levels 1–5) to show main sections and subsections.
 * All text double-spaced, paragraphs indented.
  1. References page
    • New page after the main text.
    • The word “References” centered and in bold at the top.
 * Entries in alphabetical order by the first author’s last name, with a hanging indent.

Some assignments also include an abstract (a short 150–250 word summary of the paper) on its own page after the title page, but many student papers omit this unless the instructor requires it.

In-text citations in APA

APA uses an author–date system for in-text citations:

  • One author: (Smith, 2023).
  • Two authors: (Smith & Jones, 2023).
  • Three or more authors: (Smith et al., 2023).

You include:

  • The author’s last name.
  • The year of publication.
  • Page number for direct quotes (e.g., (Smith, 2023, p. 15)).

These brief citations point the reader to the full entry on the references page.

Reference list basics

Every source you cite in the text should appear in the reference list, and every item in the reference list should be cited in the text.

General rules:

  • Alphabetize by the first author’s last name.
  • Use a hanging indent (first line at the margin, subsequent lines indented).
  • Follow the pattern: Author. (Year). Title. Source.
  • Format changes slightly for books, journal articles, websites, etc.

Example pattern for a journal article (simplified):
Author, A. A. (Year). Title of article. Title of Journal, volume(issue), pages.

Why APA format matters now

  • It’s required by many colleges and universities for papers in social sciences and health fields.
  • It creates a consistent, professional look across work, which helps readers focus on content instead of formatting.
  • Knowing APA is useful for thesis work, research reports, and publications, especially in 2025–2026 where APA 7 is the default in most updated guides.

Mini “story-style” example

Imagine you’re writing a psychology paper on social media and anxiety. In APA format , your assignment might look like this:

  • A clean title page:
    “Social Media Use and Anxiety in College Students” centered in bold, your name and university beneath, all double-spaced.
  • The first page of text starts with the same title at the top, then the introduction paragraph, indented, double-spaced.
  • Midway, you add a heading like “Method” in bold and centered, then “Participants” as a left-aligned bold heading under it.
  • When you summarize a study by Smith and Jones published in 2023, you write:
    “Recent work suggests that heavy social media use is linked with higher anxiety levels (Smith & Jones, 2023).”
  • At the end, your references page lists the full details for Smith and Jones with a hanging indent, in alphabetical order with your other sources.
