An abstract is a concise summary that provides an overview of the essential content in a larger document, such as a research paper, thesis, or report. It typically includes a snapshot of the main arguments, methods, findings, and conclusions. Abstracts are positioned at the beginning of a document to give readers a quick understanding of its content without requiring them to read the entire work. By highlighting the document’s key points, an abstract helps readers assess its relevance to their own interests or research objectives. This ability to gauge a document’s value and topic at a glance makes abstracts particularly useful in academic, scientific, and technical fields, where readers often seek specific information.
Types of Abstracts
Overview
There are two primary types of abstracts—descriptive and informative. Each serves a unique purpose depending on the document’s field or style. While descriptive abstracts provide a summary of the content’s scope and purpose, informative abstracts offer a detailed overview, including results and conclusions. Understanding the differences between these types helps writers choose the format that best suits their document.
Descriptive Abstract
- Definition: A descriptive abstract provides a brief overview, usually within 50–100 words, focusing on the document’s scope, purpose, and methodology. It does not include specific details like findings or conclusions, making it a high-level summary rather than a comprehensive one.
- Example: “This paper examines the impact of urbanization on bird migration patterns, focusing on how city landscapes influence migratory routes.”
- Common Uses: Descriptive abstracts are frequently used in humanities and social sciences, where the main goal is often to introduce the topic and context rather than report empirical results.
Informative Abstract
- Definition: An informative abstract offers a more comprehensive summary, generally within 150–250 words, and includes specific information such as the research question, methodology, major findings, and conclusions. It provides enough detail for readers to understand the key points of the document without reading it in full.
- Example: “This study analyzes the effect of urbanization on bird migration, showing that urban environments significantly alter migratory paths. Through GPS tracking, researchers observed that 60% of birds adjusted their routes in response to urban areas.”
- Common Uses: Informative abstracts are common in scientific, technical, and research documents, where readers often need a clear and detailed understanding of the study’s scope, methods, and results to decide if it is relevant to their research.
This introduction to abstract types highlights the flexibility of abstracts in conveying essential information efficiently, helping readers and researchers quickly decide if a document is worth further examination.
How to Write an Effective Abstract
Creating an effective abstract involves summarizing a larger work’s core ideas in a way that is both clear and concise. A well-structured abstract should include the following essential components:
- Purpose: Clearly state the purpose of the study or document. This is often a brief description of what the research aimed to investigate or accomplish.
- Problem: Define the main issue or research question that the study addresses. This provides context for why the study was conducted and why it is relevant.
- Methodology: Offer a concise summary of the methods used in the study. This can include the type of research, data collection techniques, or analytical approaches used.
- Results: Outline the main findings of the study. For informative abstracts, specific results are crucial, as they allow readers to assess the study’s contributions to the field.
- Conclusion: Explain the significance of the results or their implications. This section might answer questions like: How do these findings contribute to the field? Are there any practical applications or theoretical implications?
Tips for Writing an Effective Abstract
- Brevity: Keep the abstract within the word limit, typically between 150 and 250 words for an informative abstract. Avoid unnecessary words or overly complex sentences.
- Clarity: Use clear and precise language. Avoid jargon or technical terms unless they are essential to understanding the study.
- Relevance: Focus only on the most essential information. The abstract should allow readers to grasp the key points quickly and decide if they need to read the full document.
Examples of Effective Abstracts
Descriptive Abstract Example
“This paper explores the impact of social media on mental health among teenagers, focusing on how different platforms affect self-esteem and social behaviors. The study examines a range of research findings to determine common patterns and concerns in the influence of social media use.”
Informative Abstract Example
“This study investigates the impact of social media on mental health among teenagers, analyzing how various platforms influence self-esteem and social behavior. Using a survey of 1,000 adolescents, we found that high levels of social media use are associated with lower self-esteem and increased social anxiety. These findings suggest a need for further research on platform-specific effects and underscore the importance of monitoring social media use among vulnerable age groups.”
These examples show how to concisely convey the purpose, problem, methods, results, and conclusions, tailored to the type of abstract used.

Frequently Asked Questions (FAQ) About Writing Abstracts
1. What is the purpose of an abstract?
An abstract is a concise summary of a larger document, such as a research paper, thesis, or report. Its main purpose is to provide readers with a brief overview of the document’s key points—like the research question, methods, results, and conclusions—so they can quickly determine whether the full document is relevant to their interests or research. It allows readers to understand the essence of the document without having to read the entire text. Source: UNC Writing Center.
2. What are the two main types of abstracts?
The two main types of abstracts are descriptive and informative:
- Descriptive Abstract: This is a brief, 50–100 word summary that highlights the document’s scope, purpose, and methods, but excludes specific results or conclusions. It’s typically used in the humanities and provides a high-level overview of the study.
- Informative Abstract: More detailed (usually 150–250 words), this abstract includes the purpose, methods, major findings, and conclusions of the study. It is commonly used in scientific and technical papers to give a fuller picture of the research. Source: PaperDue.
3. How do I write an effective abstract?
To write an effective abstract, ensure you include the following key elements:
- Purpose: State the main objective or goal of the study.
- Problem: Define the research question or problem.
- Methodology: Briefly describe the research methods or approach used.
- Results: Summarize the main findings or outcomes of the study.
- Conclusion: Explain the significance or implications of the findings.
Tips for writing: Keep your abstract concise, clear, and focused on the most important aspects of your research. Avoid jargon and ensure that the abstract accurately reflects the content of the document. Source: UNC Writing Center.
4. What’s the difference between a descriptive and an informative abstract?
A descriptive abstract gives a general overview of the topic, purpose, and methods without delving into results or conclusions. It is used mainly in the humanities for papers where the focus is on the exploration of a subject rather than empirical findings. An informative abstract, on the other hand, is more detailed and includes results, findings, and conclusions, making it suitable for scientific and technical papers. Source: PaperDue.
5. How long should an abstract be?
An abstract typically ranges between 150–250 words. The length can vary depending on the type (descriptive or informative) and the discipline. Descriptive abstracts are generally shorter (50–100 words), while informative abstracts are longer (150–250 words) as they summarize the research findings. Source: UNC Writing Center.
6. Can I write an abstract without knowing all the results of my research?
It is not advisable to write an abstract until you have a clear understanding of the results of your research. The abstract is a reflection of the complete document, so it should accurately summarize all aspects, including the results and conclusions. If your research is ongoing, focus on writing an abstract once you have a complete set of results. Source: PaperDue.
