If you have ever embarked on the journey of writing a thesis, dissertation, or a comprehensive research paper in Brazil—or for a Brazilian academic institution—you have undoubtedly encountered the formidable acronym: ABNT. What do you need to consider about formatação abnt.
For many students and researchers, the actual research is the easy part. The true test of patience begins when it is time to format the document. Trying to remember exactly where a page number belongs, how many centimeters an indent should be, or how to correctly format a reference list can feel like deciphering an ancient code.
However, ABNT formatting does not have to be a nightmare. Once you understand the underlying logic and familiarize yourself with the core rules, it becomes a straightforward checklist. Whether you are drafting a term paper, a master’s thesis, or a scientific article, mastering these rules ensures that your work is evaluated on its intellectual merit rather than distracted by visual inconsistencies.
In this comprehensive, expert-led guide, we will break down every aspect of ABNT standards. From the meticulous page margins to the complexities of reference lists, this guide is designed to be your ultimate companion in achieving academic excellence.
What is ABNT and Why Does It Matter?
ABNT stands for Associação Brasileira de Normas Técnicas (Brazilian Association of Technical Standards). Founded in 1940, this private, non-profit organization is responsible for technical standardization in Brazil across virtually all industries—from construction and manufacturing to information technology and academia.
In the academic realm, ABNT provides a uniform set of rules that dictate how scientific knowledge should be structured and presented. The goal is simple: standardization. When every academic document follows the same visual and structural language, researchers can easily navigate documents, locate citations, and verify sources. It levels the playing field, ensuring that a thesis published in São Paulo is universally readable and structurally identical to one published in Amazonas.
While universities sometimes adapt minor details to fit their specific institutional manuals, the backbone of all Brazilian academic writing relies on specific ABNT standards (known as NBRs).
Core NBRs You Need to Know
Before we dive into the practical formatting, it is helpful to know the specific technical norms that govern academic papers. You do not need to read these original documents (as they can be quite dense), but understanding what they cover will clarify why certain rules exist.
- NBR 14724: Specifies the general principles for formatting academic works, including theses, dissertations, and the standardized layout for TCC (Trabalho de Conclusão de Curso).
- NBR 6023: The ultimate rulebook for formatting references at the end of your document.
- NBR 10520: Dictates how to format quotes and citations within the text.
- NBR 6024: Details the progressive numbering of sections in a document.
- NBR 6027: Explains how to format the summary or table of contents.
- NBR 6028: Provides the guidelines for writing abstracts and summaries.
Now, let us move from theory to practice and set up your document.
General Document Setup: The Canvas of Your Paper
Before writing a single word, you must set up your word processor. Getting the basic canvas right will save you countless hours of reformatting later.
Paper Size, Font, and Alignment
- Paper Size: A4 (21 cm x 29.7 cm).
- Font: You must use a legible, professional font. The two universally accepted options are Arial or Times New Roman. Once you choose one, you must use it consistently throughout the entire document.
- Font Size:
- Size 12 for the main text, section titles, and headings.
- Size 10 for long direct citations (quotes over three lines), footnotes, table captions, figure sources, and pagination.
- Alignment: The main text must be Justified (aligned evenly along the left and right margins).
Standard Academic Margins and Spacing
One of the most rigid rules in ABNT formatting dictates the white space around your text. Applying standard academic margins and spacing ensures your paper looks professional and allows physical copies to be bound without text being cut off.
Margins:
- Top Margin: 3 cm
- Left Margin: 3 cm (This extra space accounts for binding).
- Right Margin: 2 cm
- Bottom Margin: 2 cm
Line Spacing:
- The general text requires 1.5 line spacing.
- Single spacing (1.0) is reserved for specific elements: long direct citations, footnotes, references at the end of the document, and data on the approval sheet.
Paragraph Indentation: The first line of every standard paragraph should be indented by 1.25 cm (or simply standard Tab distance in most word processors) from the left margin.
Page Numbering Rules for Monographs
Getting the page numbers right is often a source of frustration. The page numbering rules for monographs under ABNT are very specific:
- Counting vs. Displaying: Page counting begins on the title page (Folha de Rosto), which is the second page of your document. However, the numbers are not displayed on any of the pre-textual elements (like the abstract, table of contents, or dedication).
- When to Show Numbers: The physical number only appears starting on the first page of the textual part of your document—usually the Introduction.
- Position: Page numbers must be placed in the upper right corner of the page, 2 cm from the top and 2 cm from the right edge. They must be written in Arabic numerals (1, 2, 3…) using a size 10 font.
The NBR 14724 Structural Guidelines: Organizing the Document
A research paper is not just an essay with a title. According to the NBR 14724 structural guidelines, an academic work is divided into three distinct blocks: Pre-textual elements, Textual elements, and Post-textual elements.
Understanding the pre-textual elements of an academic thesis is crucial because these pages build the professional facade of your research. Some elements are mandatory, while others are optional.
1. Pre-Textual Elements
These elements introduce your work and help catalog it.
- Cover Page (Capa) – Mandatory: The cover page requirements for assignments, monographs, and theses include the name of the institution, the author’s full name, the title of the work (and subtitle, if any), the city of the institution, and the year of submission. All text is centered, bolded, and properly spaced.
- Title Page (Folha de Rosto) – Mandatory: This page repeats the author’s name and the title, but it also includes an explanatory note aligned to the middle-right of the page. This note specifies the nature of the work (e.g., “Thesis presented to the Faculty of Engineering to obtain a Master’s Degree”) and names the academic advisor.
- Cataloging Sheet (Ficha Catalográfica) – Mandatory for theses/dissertations: Usually provided by the university’s library, it is printed on the back of the title page.
- Errata – Optional: Inserted right after the title page if errors were discovered after printing.
- Approval Sheet (Folha de Aprovação) – Mandatory: Contains the names and signatures of the examining committee members and the date of approval.
- Dedication (Dedicatória) – Optional: A short text dedicating the work to someone. Usually placed at the bottom right of a new page.
- Acknowledgments (Agradecimentos) – Optional: A section to thank those who contributed academically, financially, or personally to the research.
- Epigraph (Epígrafe) – Optional: A quote that reflects the theme of the work, placed at the bottom right of the page.
- Abstract in the Vernacular (Resumo) – Mandatory: A single paragraph (typically 150 to 500 words for academic papers) summarizing the objective, methodology, results, and conclusion of the work. It must be followed by keywords (Palavras-chave).
- Abstract in a Foreign Language (Abstract/Résumé/Resumen) – Mandatory: The exact translation of your abstract and keywords into English, French, or Spanish.
- Lists (Illustrations, Tables, Abbreviations) – Optional but recommended: If your paper has multiple visual elements, create separate lists for figures, tables, and abbreviations.
- Table of Contents (Sumário) – Mandatory: A detailed list of the main sections and subsections of your document, exactly as they appear in the text, accompanied by their respective page numbers.
2. Textual Elements
This is the core of your research. While ABNT does not dictate the specific content, it expects a logical, scientific progression.
- Introduction: Presents the theme, the research problem, hypotheses, objectives, and justification.
- Development: The longest part of the text. It usually contains the literature review, methodology, data presentation, and discussion of results. This section is heavily divided into chapters and sub-chapters.
- Conclusion (or Final Considerations): A concise summary of the findings, directly answering the research problem posed in the introduction.
3. Post-Textual Elements
These sections provide supporting material and source validation.
- References (Referências) – Mandatory: A comprehensive, strictly formatted list of all works cited in the text.
- Glossary (Glossário) – Optional: A list explaining technical terms used in the text.
- Appendices (Apêndices) – Optional: Materials created by the author to support the text (e.g., a blank copy of the questionnaire used in the research).
- Annexes (Anexos) – Optional: Supporting materials created by a third party (e.g., a copy of a legal document, a map, or a historical photograph).
Mastering In-Text Citations: The NBR 10520 Standard
Academic writing is an ongoing conversation with previous researchers. To participate, you must cite your sources. Under ABNT, citations are primarily managed using the author-date system for in-text citations.
Citations fall into two main categories: Direct (quoting the author word-for-word) and Indirect (paraphrasing the author’s ideas).
1. Indirect Citations
Indirect citations occur when you explain another author’s concept using your own words. You must still credit the original author and state the year of publication. Including the page number is optional but recommended.
Examples:
- According to Silva (2021), the impact of climate change on local agriculture is undeniable.
- The impact of climate change on local agriculture is undeniable (SILVA, 2021).
Notice the capitalization rule: When the author’s name is incorporated into the flow of your sentence, only the first letter is capitalized. When the author’s name is placed inside the parentheses at the end of the sentence, it must be in ALL CAPS.
2. Direct Citations: Short versus Long Direct Citations
When you quote an author exactly as written in the original source, you are making a direct citation. ABNT has strict visual distinctions based on the length of the quote.
Short Direct Citations (Up to 3 lines): If the quote takes up three lines or fewer in your document, it remains integrated into your standard paragraph. It must be enclosed in double quotation marks. The author’s name, the year, and the exact page number are mandatory.
- Example: As Oliveira (2019, p. 45) states, “the evolution of formatting software has reduced the time students spend on administrative tasks.”
- Example: “The evolution of formatting software has reduced the time students spend on administrative tasks” (OLIVEIRA, 2019, p. 45).
Long Direct Citations (More than 3 lines): If the quote exceeds three lines, you must follow the rules for short versus long direct citations to visually separate the text. Long citations cannot have quotation marks. Instead, they require a specific block format:
- Indentation: The entire quote must be indented 4 cm from the left margin.
- Font Size: Reduced to size 10.
- Line Spacing: Single spacing (1.0).
- Blank Lines: You must leave one blank line (1.5 spacing) before and after the citation block to separate it from your main text.
Visual Example: [Main text, size 12, 1.5 spacing] Therefore, understanding the methodology requires a deeper look into the original manual. According to Costa (2020, p. 112):
[Indented 4cm, size 10, single spaced] The qualitative approach in this specific scenario allows the researcher to bypass rigid statistical frameworks. Instead, it invites a deeper psychological interpretation of the subjects, granting access to emotional data that a simple numerical survey would ultimately fail to capture in its entirety.
3. Citation of a Citation (Apud)
Sometimes, you will read Author A quoting Author B, but you cannot find Author B’s original book. In this case, you use the Latin expression apud (which means “cited by”).
- Example: The educational structure must be reformed from the ground up (DEWEY, 1938 apud FREIRE, 1996, p. 55).
- Note: In your final reference list, you will only include Freire’s book, because that is the physical book you actually read.
Building the Reference List: NBR 6023 Bibliographic References Guide
The reference section is arguably the most intimidating part of ABNT formatting. The NBR 6023 bibliographic reference guide sets out meticulous rules for crediting different types of sources.
General Rules for the Reference List:
- Heading: The word REFERENCES must be centered and bolded at the top of a new page.
- Alignment: Unlike the main text, references must be aligned only to the left. (Do not justify the reference list).
- Spacing: Single spacing (1.0) within the reference, with one blank line (single spaced) between each reference.
- Order: Alphabetical order by the first author’s surname.
- Highlighting: The main title of the work must be highlighted (you can use bold, italics, or underlining, but you must be consistent; bold is the most common choice).
Let us look at templates for the most common source types.
Citing Books
Format: SURNAME, First Name. Title in bold: subtitle in normal text. Edition number (if not the first). City of publication: Publisher, Year.
- One Author: SANTOS, Milton. A natureza do espaço: técnica e tempo, razão e emoção. 4. ed. São Paulo: Edusp, 2004.
- Two or Three Authors (Separate with semicolons): LAKATOS, Eva Maria; MARCONI, Marina de Andrade. Fundamentos de metodologia científica. 8. ed. São Paulo: Atlas, 2017.
- Four or More Authors: You can use the Latin expression et al. (and others) after the first author. SILVA, João et al. Avanços na tecnologia médica. Rio de Janeiro: Editora Saúde, 2022.
Citing Academic Journals and Articles
For articles, the name of the journal is highlighted, not the title of the article.
Format: SURNAME, First Name of the article’s author. Title of the article. Title of the Journal in bold, City, volume, number, page range, month, and year.
- Example: PEREIRA, Carlos. A inovação no ensino digital. Revista Brasileira de Educação, Rio de Janeiro, v. 15, n. 3, p. 100-115, mar. 2021.
How to Cite Websites Using ABNT
In the digital age, much of our research happens online. The rules for how to cite websites using ABNT require you to capture not just the URL, but the exact date you accessed the information, because webpages can change or disappear.
Format: AUTHOR OR ORGANIZATION. Title of the page/article. Name of the Website, Year (if available). Available at:. Accessed on: day month. year.
Citing Theses and Dissertations
Format: SURNAME, First Name. Title of the thesis. Year. Number of pages. Type of document (Degree) – Academic Department, University, City, Year of defense.
- Example: ALMEIDA, Roberto. Sustentabilidade corporativa. 2019. 150 f. Dissertação (Mestrado em Administração) – Faculdade de Economia, Universidade de São Paulo, São Paulo, 2019.
Visual Data: Formatting Tables and Figures Guide
Academic papers often rely on visual data to convey complex information efficiently. Whether you are using a photograph, a flowchart, a graph, or a table, there are strict rules governing their presentation.
According to the ABNT formatting tables and figures guide, every visual element must be self-explanatory and explicitly linked to the text.
Formatting Figures (Images, Graphs, Charts)
- Placement: Insert the figure as close as possible to the paragraph where it is first mentioned.
- Callout: You must mention the figure in the text before it appears. (e.g., “As demonstrated in Figure 1, the growth was exponential…”).
- Title/Caption: Place the title above the image. It should read “Figure X – Title of the figure”. Use a font size of 10 or 12 (be consistent).
- Source: Place the source below the image. Even if you created the image yourself, you must state it. (e.g., “Source: Elaborated by the author (2023)”). Use size 10 font, single spaced.
Formatting Tables
While figures show visual trends, tables are designed to present exact, structured numerical data. In Brazilian academic formatting, tables follow guidelines set not only by ABNT but also by the IBGE (Brazilian Institute of Geography and Statistics).
- Borders: A true table in ABNT does not have closed vertical lines on the left and right edges. It should look open on the sides. Horizontal lines are primarily used to separate the header row from the data, and to close the bottom of the table.
- Title: Placed above the table. (e.g., “Table 1 – Population growth by region”).
- Source: Placed below the table, just like figures.
Global Context: APA vs ABNT Citation Styles
If you are an international student studying in Brazil, or a Brazilian student submitting to international journals, you will likely run into a clash of formatting styles. The most common global standard is APA (American Psychological Association).
Understanding the differences in APA vs ABNT citation styles can save you major headaches during peer review or grading.
1. Margins and Spacing:
- APA: Requires 1-inch (2.54 cm) margins on all sides and double spacing (2.0) throughout the entire document.
- ABNT: Uses the 3cm/2cm rule and 1.5 line spacing.
2. In-Text Citations:
- APA: Uses Title Case for authors in text and uses an ampersand (&) inside parentheses. Example: (Smith & Doe, 2020).
- ABNT: Uses ALL CAPS inside parentheses and spells out the word “and” (or “e” in Portuguese) or uses a semicolon. Example: (SMITH; DOE, 2020).
3. Long Direct Citations:
- APA: Block quotes begin at 40 words, are indented 0.5 inches, and keep the standard double spacing and font size.
- ABNT: Block quotes begin at 4 lines, heavily indented at 4 cm, with a reduced font size (10pt) and single line spacing.
4. Reference Lists:
- APA: Uses a hanging indent (the second line of each reference is indented). Focuses heavily on the year, placing it immediately after the author’s name. It highlights the title in italics.
- ABNT: Aligned strictly to the left (no hanging indent). The year is placed at the very end of the reference string. The title is highlighted in bold (usually).
Practical Setup: Setting up an Academic Template for Google Docs and Word
You don’t need to manually adjust margins and fonts every single time you start a new assignment. By creating an academic template for Google Docs or Microsoft Word, you can automate 90% of the ABNT requirements.
Step-by-Step for Google Docs
- Set the Margins: Go to File > Page setup. Ensure the paper size is A4. Set Top to 3, Bottom to 2, Left to 3, and Right to 2. Click “Save as default” if you want this to apply to all future documents.
- Set the Font: Select Arial or Times New Roman, size 12.
- Set Line Spacing: Click the Line & paragraph spacing icon. Select Custom spacing. Set line spacing to 1.5. Ensure “Before” and “After” paragraph spacing are set to 0.
- Set Paragraph Indent: Go to Format > Align & indent > Indentation options. Under “Special indent”, choose “First line” and set it to 1.25 cm.
- Create Styles: Type a sample chapter title (e.g., “1. INTRODUCTION”). Make it bold, size 12, uppercase. Highlight it, go to the styles dropdown menu (where it says ‘Normal text’), hover over ‘Heading 1’, and click “Update Heading 1 to match”. Now, every time you click Heading 1, it will format your ABNT chapter titles perfectly.
- Save as Template: Save this blank document as “MASTER ABNT TEMPLATE”. Every time you have a new assignment, make a copy of this file.
Step-by-Step for Microsoft Word
Microsoft Word offers robust style management, making ABNT formatting incredibly stable.
- Margins: Go to Layout > Margins > Custom Margins. Set Top/Left to 3cm and Bottom/Right to 2cm.
- Modify the ‘Normal’ Style: Right-click the ‘Normal’ style on the Home ribbon, then click Modify. Set it to Arial/Times New Roman, size 12, Justified. Click Format > Paragraph. Set Line Spacing to 1.5, Before/After spacing to 0pt. Under ‘Special’, select ‘First line’ and set to 1.25 cm.
- Create a ‘Long Citation’ Style: Create a new style based on ‘Normal’. Name it “ABNT Quote”. Modify it: Font size 10, Single line spacing. In the Paragraph settings, remove the First Line indent. Instead, set the overall Left Indentation to 4 cm. Set ‘Spacing Before’ and ‘Spacing After’ to 12pt (to simulate the blank line). Now, whenever you have a long quote, just highlight the text and click the “ABNT Quote” style button.
Tech to the Rescue: Leveraging Automation
You do not have to memorize every comma and period in the reference rules. Technology can do the heavy lifting for you.
Using a citation generator for Brazilian standards is highly recommended to save time and reduce errors. Tools like MORE (Mecanismo Online para Referências), developed by the Federal University of Santa Catarina (UFSC), are lifesavers. You simply plug in the ISBN of a book, or the URL of a website, and the system automatically generates a perfectly formatted ABNT reference.
Reference management software such as Mendeley, Zotero, and EndNote also offer downloadable ABNT plugins. These programs integrate directly into Microsoft Word or Google Docs, allowing you to insert citations as you type. When you are finished writing, clicking a single button will generate your entire reference list in flawless alphabetical order.
However, a word of caution: Always double-check automated citations. Generators can sometimes pull data incorrectly (like putting an entire title in uppercase or messing up author names if the website’s metadata is wrong). The human eye is still required for the final polish.
Common Layout Errors in Research Papers
Even with templates and generators, students frequently make mistakes that can cost them points on their final grade. Being aware of the common layout errors in research papers is half the battle. Here is a checklist of pitfalls to avoid:
- Orphan and Widow Lines: Leaving a single line of a paragraph at the very bottom of a page (orphan) or the very top of the next page (widow). Adjust your spacing or text to keep paragraphs together. Word processors have “Widow/Orphan control” settings in the paragraph menu to prevent this automatically.
- Misaligned Summary/TOC: Manually typing dots (……..) to connect a chapter title to its page number in the Table of Contents. This guarantees jagged, misaligned numbers. Always use the automatic Table of Contents feature in Word or Google Docs, which formats the leader dots perfectly.
- Inconsistent Font Sizes: Forgetting to shrink the font to size 10 for long direct quotes, footnotes, or image captions.
- Bold and Italic Overload: Using bold text for emphasis in the middle of a paragraph. Under ABNT, emphasis should generally be done with italics. Bold is reserved for titles, headings, and highlighting the main title in the reference list.
- Forgetting the Foreign Language Abstract: Submitting a thesis with only a Portuguese Resumo. The English Abstract (or Spanish/French equivalent) is a mandatory pre-textual element for TCCs and monographs.
- Justifying the Reference List: Highlighting the entire document and clicking “Justify”. Remember, the reference list is the only major text block that must be aligned exclusively to the left. Justifying it creates awkward, large white spaces between words, especially in long URLs.
- Incorrect Spacing Around Headings: Failing to leave visual breathing room. ABNT requires one blank line (1.5 spacing) before and after a section heading to separate it from the text.
- Pasting URLs as Blue Hyperlinks: When you paste a URL in a reference, word processors automatically turn it blue and underlined. ABNT requires the text to be standard black, with no underline. You must right-click and “Remove Hyperlink”.
Conclusion: Embrace the Structure
While the myriad of rules might seem pedantic, mastering ABNT formatting is ultimately a rite of passage for any academic operating within the Brazilian educational sphere. It shifts your mindset from being just a “student” to being a “researcher.”
By setting up an academic template early, utilizing citation generators smartly, and understanding the core logic behind the margins, spacings, and structural blocks, you eliminate the friction of formatting. You free up your mental energy for what truly matters: your research, your critical thinking, and your academic voice.
Take it step by step, refer back to the NBR guidelines when in doubt, and remember that every perfectly formatted page brings you one step closer to academic success. Happy writing!
