How to Write an APA Abstract: Format, Steps, and Example

An APA abstract is a brief summary of a research paper, usually 150–250 words long, placed on a separate page after the title page. In APA 7, the abstract is typically written as one double-spaced paragraph with no first-line indent. It summarizes the research problem, purpose, methods, results, and implications so readers can quickly understand what the paper is about. Below, you’ll learn how to format an APA abstract, what to include, how to write keywords, and what a finished abstract should look like.

What Is an APA Abstract?

An abstract written in APA style is a concise summary of the main points of a research paper. It follows the rules of the APA format and usually includes the research problem, purpose, methods, key findings, and conclusion. The abstract helps readers decide whether the paper is relevant to their topic before they read the full text.

A strong APA abstract is important because it:

• Gives readers a quick overview of the paper’s topic and purpose.
• Explains the research problem, method, results, and conclusion in a condensed form.
• Helps readers evaluate whether the paper is useful for their research.
• Improves discoverability when keywords are required for academic databases.
• Creates a clear first impression of the paper’s academic value.

Student papers do not always need an abstract. Many APA student assignments only require one if the instructor specifically asks for it. Professional papers, theses, dissertations, and journal submissions are more likely to require an abstract.

APA Abstract Format at a Glance

Before writing the abstract, make sure you understand the basic APA abstract format rules. The exact requirements may vary depending on your instructor, university, or journal, but the standard APA abstract usually follows these guidelines:

APA abstract element	Correct format
Placement	On a separate page after the title page
Page number	Top right corner of the page
Heading	The word “Abstract,” centered and bold
Length	Usually 150–250 words
Paragraph format	One double-spaced paragraph
First-line indent	No first-line indent for the abstract paragraph
Content	Research problem, purpose, methods, results, and implications
Keywords	Optional unless required; usually 3–5 keywords
Keyword label	“Keywords:” italicized and indented 0.5 inches

How to Write an APA Abstract Step by Step

To write an effective APA abstract, summarize the full paper after you have finished the main draft. This helps you avoid vague claims and ensures that the abstract accurately reflects the paper’s final argument, method, findings, and conclusion.

Before You Write the Abstract

• Review the assignment requirements. Check whether your instructor requires an abstract, a specific word count, keywords, or a structured abstract.
• Reread the full paper. Identify the research problem, purpose, method, results, and conclusion before you start summarizing.
• Highlight the most important points. The abstract should not include every detail. It should only present the information readers need to understand the paper quickly.
• Write the abstract last. Even though the abstract appears near the beginning of the paper, it is easier and more accurate to write it after the full paper is complete.

What to Include in an APA Abstract

• Research problem. Start by identifying the issue, question, or gap your paper addresses.
• Purpose of the paper. Explain what the paper aims to examine, prove, compare, or analyze.
• Methods. Briefly describe the research design, source type, participants, data, or procedure if applicable.
• Results or key findings. Summarize the main outcome of the research or analysis.
• Implications. End by explaining why the findings matter or how they contribute to the topic.

Keep the abstract direct and specific. Avoid unnecessary background information, unsupported opinions, long definitions, and phrases such as “This paper will discuss” when a stronger summary is possible.

APA Abstract Structure: Purpose, Methods, Results, and Conclusion

Are you concerned about how to make an APA abstract concise, clear, and useful? A strong abstract usually follows a simple structure, even when it is written as one paragraph:

• Heading. Write the word “Abstract” at the top of the page. Center it and use bold formatting.
• Opening sentence. Introduce the research topic, problem, or question.
• Purpose. State what the paper investigates or explains.
• Methods. Briefly describe how the research or analysis was conducted.
• Results. Summarize the most important findings or conclusions.
• Implications. Explain the importance of the findings or their practical meaning.
• Keywords. If required, add a separate keywords line after the abstract.

Most APA abstracts are written as a single paragraph with no first-line indent. However, some journals or advanced research assignments may require a structured abstract with labels such as “Objective,” “Method,” “Results,” and “Conclusion.” Always follow your instructor’s or journal’s requirements first.

APA Abstract Example

Below is a simple APA abstract example for a student research paper. Use it as a model for structure only. Your own abstract should summarize your actual paper, including your specific topic, method, findings, and conclusion.

Abstract

This paper examines how social media use affects sleep quality among college students. The study reviews recent research on screen time, nighttime phone use, and sleep disruption. Findings suggest that frequent social media use before bed is associated with shorter sleep duration and lower perceived sleep quality. The paper concludes that limiting screen exposure before bedtime may help students improve sleep habits and academic performance.

Keywords: social media, sleep quality, college students, screen time, academic performance

How to Format an APA Abstract

When formatting an APA abstract, focus on the page layout, word count, spacing, indentation, heading, and keywords. Use the checklist below to make sure your abstract follows APA 7 requirements:

• Place the abstract on a separate page after the title page.
• Include the page number in the header, aligned to the right.
• Center the word “Abstract” at the top of the page and format it in bold.
• Do not italicize, underline, or place quotation marks around the abstract heading.
• Write the abstract as one double-spaced paragraph.
• Do not indent the first line of the abstract paragraph.
• Keep the abstract within the required word count, usually 150–250 words.
• Use a readable APA-approved font, such as 12-point Times New Roman, 11-point Calibri, 11-point Arial, or another font accepted by your instructor.
• Add keywords only if your instructor, university, or journal requires them.

Keywords in an APA abstract help academic databases identify the main topic of your paper. If keywords are required, place them on the line after the abstract. Indent the line by 0.5 inches, italicize the label “Keywords:”, and separate 3–5 keywords with commas. Your keywords should reflect the main topic, research variables, population, method, or field of study.

Student papers do not always require keywords. Add them only if your instructor, university, or assignment guidelines ask for them. Professional papers and journal submissions are more likely to require keywords for database indexing.

Structured vs. Unstructured APA Abstracts

Most student APA abstracts are unstructured, which means the abstract is written as one paragraph without labels such as “Purpose,” “Methods,” or “Results.” This is the format most students will use for class assignments.

A structured abstract separates information into labeled sections. This format is more common in journal articles, scientific papers, medical research, and professional submissions. If your assignment instructions do not mention a structured abstract, use the standard one-paragraph format.

APA Abstract vs. Introduction

An abstract and an introduction are not the same. The abstract summarizes the entire paper, including the purpose, methods, results, and conclusion. The introduction begins the main body of the paper, gives background information, and leads into the thesis or research question.

Another key difference is placement. The abstract appears before the main body of the paper, while the introduction is the first section of the paper itself. Write the abstract after finishing the paper so it accurately reflects what the paper contains.

Common APA Abstract Mistakes to Avoid

Even a well-written abstract can lose points if the formatting or content is inaccurate. Avoid these common mistakes:

• Writing too much. An APA abstract should usually stay within 150–250 words unless your instructor gives a different limit.
• Indenting the first line. The abstract paragraph should not have a first-line indent.
• Using the wrong heading format. The heading should be “Abstract,” centered and bold.
• Adding citations unnecessarily. An abstract usually summarizes your own paper and does not need citations.
• Including vague claims. Avoid broad statements that do not explain the specific purpose, method, result, or implication of your paper.
• Writing the abstract before the paper is complete. This often leads to inaccurate summaries or missing findings.
• Forgetting assignment requirements. Some instructors may require keywords, a shorter word count, or a structured abstract.

APA Abstract Checklist Before Submission

Before submitting your paper, use this quick checklist to review your APA abstract:

• The abstract is on a separate page after the title page.
• The page number appears in the top right corner.
• The heading “Abstract” is centered and bold.
• The abstract is written as one paragraph.
• The first line of the abstract is not indented.
• The abstract is double-spaced.
• The abstract is within the required word count.
• The abstract summarizes the research problem, purpose, methods, results, and implications.
• Keywords are included only if required.
• The keywords line uses the italicized label “Keywords:” and 3–5 relevant terms.
