In APA format, every body paragraph starts with a first-line indent of 0.5 in., is double-spaced like the rest of the paper, is aligned to the left margin with a ragged right edge, and has no extra space before or after it. That is the whole APA-specified layout; how long a paragraph should be and how it is built are writing conventions that vary by instructor. This guide separates the two and gives you a fill-in template and a worked example. Style edition checked: APA 7th edition (2020), as of October 2026, against the official APA Student Paper Setup Guide.
What APA 7 specifies for body paragraphs
The APA Student Paper Setup Guide (7th edition; https://apastyle.apa.org/instructional-aids/student-paper-setup-guide.pdf, checked 29 October 2026) sets these rules for the text of a paper:
- First-line indent: indent the first line of every paragraph of text 0.5 in., using the tab key or your word processor’s paragraph-formatting function, not the space bar.
- Line spacing: double-space the entire paper, including block quotations and the reference list. Do not add blank lines before or after headings, and do not add extra spacing before or after paragraphs.
- Alignment: align paragraphs to the left margin and leave the right margin ragged. Do not use full justification.
- Margins and font: 1 in. margins on all sides, and a legible font used throughout. The guide names 12-pt Times New Roman, 11-pt Calibri, 11-pt Arial, 11-pt Georgia and 12-pt Aptos as acceptable examples; see what size font APA format uses.
- No “Introduction” label: the text begins with the introduction, but you do not label it “Introduction” unless asked. The beginning of the text is assumed to be the introduction.
This is a student-paper rule set. A professional manuscript for journal submission can have its own requirements, and instructors may override any of these, so check your assignment instructions first.
What APA does not specify: paragraph length and structure
The setup guide gives no sentence count and no required internal structure for a body paragraph. Advice on length comes from instructors and library handouts, and it differs. For example, a 2025 library handout from Drake State Community and Technical College (“APA Paper Formatting v1.5, 7th edition”) suggests body paragraphs of roughly 5 to 12 sentences that open with a topic sentence relating to the thesis, follow with supporting details and in-text citations, and end by referring back to the paragraph’s main focus. Treat that as one library’s writing advice, not as an APA rule. If your instructor gives a different range, follow your instructor.
Body paragraph template
This four-part pattern is a writing convention, not an APA requirement. It is a reasonable default for a student paper, and the filled example below shows it in use.
- Topic sentence: the one claim this paragraph supports, tied to your thesis.
- Evidence with citation: a paraphrase or short quotation from a source, with an author-date citation, for example (Author, year) or Author (year). Direct quotations also need a page number: (Author, year, p. 20).
- Analysis: one or two sentences saying what the evidence shows and why it matters for your argument. This is where your own voice goes.
- Link-back sentence: a closing sentence that returns to the paragraph’s focus or points to the next paragraph.
Template with placeholders (indent the first line 0.5 in. and double-space it):
[Topic sentence stating the single claim.] [Evidence: paraphrase of what a source found] (Author, year). [Second piece of evidence or a short direct quotation] (Author, year, p. #). [Analysis: what the evidence shows and why it supports your thesis.] [Link-back sentence that closes the paragraph.]
Filled example (fictional content)
Illustration only. The authors, studies and findings below are invented to show the format. They are not real sources and would not appear in a real reference list.
Peer feedback on drafts appears to improve revision quality more reliably when students receive it before the final week of a course. Brandt et al. (2022) reported that students who exchanged drafts early made more substantive revisions than students who exchanged drafts at the end. A second study of first-year writers found the same pattern (Okoro et al., 2021). Taken together, these findings suggest that the timing of feedback matters as much as its quality, because late feedback leaves little room to act on it. Early peer review, then, is the more defensible choice for a course with a fixed deadline.
What to notice in the example: one topic sentence, two cited pieces of evidence (three or more authors, so “et al.” appears from the first citation on), one analysis sentence, and a closing sentence that ties back to the claim. In the paper itself, the first line is indented 0.5 in. and there is no blank line between this paragraph and the next. In-text citation format: a comma between author and year in a parenthetical citation; for a source with three or more authors, the first author’s surname plus “et al.” in every citation. See the APA In-Text Citation Checklist for the full author-date rules.
Body paragraphs under headings
Paragraph text under a heading follows the same rules as any other body text. Two heading-related points from the setup guide matter for paragraphs:
- Do not add blank lines before or after a heading. Level 1 to 3 headings sit on their own line, and the body paragraph starts on the next double-spaced line with a normal first-line indent.
- Level 4 and Level 5 headings are run-in: the heading is indented like a paragraph, ends with a period, and the text continues on the same line as a regular paragraph.
The guide also says to avoid having only one subsection within a section. For the heading levels themselves, see the guide to writing a research paper in APA style.
Block quotations inside a paragraph
A quotation of 40 words or more is set as a block: double-spaced, indented 0.5 in. from the left margin, with no quotation marks (APA In-Text Citation Checklist). Shorter quotations stay in the paragraph inside double quotation marks, with author, year and page number. The block quote does not change the double-spacing rule, since the setup guide says to double-space block quotations too. For worked quotation examples, see citing a quote: examples.

| Check | Source of the rule |
|---|---|
| First line of every paragraph indented 0.5 in. with the tab key or paragraph formatting, not the space bar | APA Student Paper Setup Guide (7th ed.) |
| Double-spaced throughout, including block quotations and the reference list | APA Student Paper Setup Guide (7th ed.) |
| No extra space before or after paragraphs, and no blank lines around headings | APA Student Paper Setup Guide (7th ed.) |
| Left-aligned, ragged right, not justified | APA Student Paper Setup Guide (7th ed.) |
| Quotations of 40 or more words set as an indented block without quotation marks | APA In-Text Citation Checklist |
| Opening of the text not labeled “Introduction” unless requested | APA Student Paper Setup Guide (7th ed.) |
| Sentence count, topic sentence, link-back sentence | Writing convention; varies by instructor (not an APA rule) |
Common setup mistakes
- Indenting with the space bar. The guide specifies the tab key or paragraph formatting.
- Leaving “space after paragraph” on. Some word-processor default styles add spacing after each paragraph, which breaks the no-extra-spacing rule.
- Justifying the text. APA calls for a ragged right margin.
- Using a hanging indent on body text. The hanging indent belongs to the reference list; see APA hanging indent.
- Labeling the opening “Introduction.” Not needed unless your instructor asks for it.
Frequently asked questions
How many sentences should an APA body paragraph have?
APA’s setup guide gives no sentence count. One college library handout suggests 5 to 12 sentences, and other guides give different ranges, so follow your instructor’s expectation and keep each paragraph to one main idea.
Do I indent the first line after a heading?
Yes. The setup guide says to indent the first line of every paragraph of text 0.5 in. The exception is a Level 4 or Level 5 heading, where the heading itself is indented and the text runs on from it on the same line.
Is there a space between paragraphs in APA format?
No. Double-space the whole paper and do not add extra spacing before or after paragraphs. The first-line indent is what marks a new paragraph.
Should APA paragraphs be justified?
No. Align text to the left margin and leave the right margin ragged.
Where do paragraph numbers or footnotes fit?
Citing a specific paragraph of a source is covered in how to cite paragraphs, and notes are covered in APA footnotes.
