How long should a research paper abstract be?

A research paper abstract is usually 150–250 words, summarising the problem, methods, key results and conclusion in one paragraph.

Which citation style for a research paper?

Use the style your target journal or department specifies — IEEE for engineering and computer science, APA for social sciences, Vancouver for medicine. Every in-text citation must map to a complete, real reference.

Research Paper Format (2026) — IMRaD Structure, Sections & Citations

Q: What is the standard research paper format?

Most research papers follow the IMRaD structure: Abstract, Introduction, Methods, Results, and Discussion, followed by a Conclusion and References. Engineering and CS papers usually use IEEE numbered citations; sciences often use APA or Vancouver.

Q: What does IMRaD stand for?

IMRaD stands for Introduction, Methods, Results, and Discussion — the four core sections of a scientific research paper, preceded by an abstract and followed by references.

Q: How long should a research paper be?

Most journal research papers run between 3,000 and 8,000 words, varying by discipline and by the individual journal. The journal's author guidelines state the limit and it should be treated as binding, since exceeding it is a common cause of desk rejection. Conference papers are typically shorter, often four to eight pages within the conference's own template.

Q: Why was my paper desk-rejected without review?

Desk rejection happens before peer review and is usually caused by the paper being outside the journal's scope, which is the single most common reason and entirely preventable by reading recent issues. Other frequent causes are failure to follow the author guidelines on word limit, reference style or section structure, no clearly articulated contribution, methodology described in too little detail to evaluate, prose an editor must reread to parse, a high similarity score on the submission screen, and undisclosed use of AI assistance, which most publishers now require to be declared.

Q: Do I have to disclose AI use in a research paper?

Most major publishers now require disclosure of AI assistance. The common position across publishers is that an AI system cannot be listed as an author, because authorship carries accountability that software cannot hold, and that any substantive use must be described in the declarations or acknowledgements section. Undisclosed use is treated as a breach of publication ethics. The safe approach is to declare the assistance, keep the research design, analysis and interpretation your own, and verify every citation.

Q: How do I choose the right journal for my paper?

Begin with scope, since a sound paper sent to the wrong journal is desk-rejected without review. Read the aims-and-scope statement and confirm that recent issues actually publish work similar to yours. Verify indexing against the index's own records, matching the ISSN against Elsevier's Scopus Source List or searching the DOAJ directory, rather than trusting a badge on the journal's website. Confirm any article processing charge before submitting rather than after acceptance, and read the author guidelines on word limits, reference style and figure requirements.

Overview

What is a research paper?

A research paper is a concise, evidence-based document that reports original work — a problem, the method used to investigate it, the results, and what they mean. Unlike a thesis, it has no certificate/declaration front matter; instead it ends with a back-matter Declarations section and a real, verifiable reference list.

For a longer document see the thesis format guide; for publication-specific rules see journal article format.

Structure

The IMRaD structure

The standard research-paper section sequence LivoDraft uses (locked for compliance — rename-only):

Abstract150–250 words: problem, methods, key results, conclusion.
IntroductionProblem, related work, research gap and your contribution.
Related Work / LiteraturePositions the paper against existing studies.
Methods / MethodologyDesign, data, materials and procedure — reproducible.
ResultsFindings with tables and figures — objective, no interpretation.
DiscussionInterpretation against the literature; implications; limitations.
ConclusionContributions restated; future directions.

Abstract

The abstract

A research-paper abstract is 150–250 words, a single paragraph covering the problem, methods, key results and conclusion. Some journals require a structured abstract (Background / Methods / Results / Conclusions labels) — LivoDraft can format either.

Back matter

Declarations

Papers replace the thesis certificate/declaration with a back-matter Declarations block before the references:

Author contributionConflict of interestFundingEthics approvalData availabilityAI-use disclosure

References

Citations & references

Engineering/CS papers use IEEE numbered citations; social sciences APA; medicine Vancouver. Every citation must map to a real, DOI-verified reference — LivoDraft builds the bibliography from genuine papers, never fabricated:

Section by section

How to write each section

Introduction

Work from broad to narrow in about four moves: why the general area matters, what is already known, what is still missing, and what this paper does about it. End with an explicit statement of your contribution. Reviewers decide early whether a paper is worth their time, and a diffuse introduction is the commonest reason they decide against it.

Methods

Write for reproducibility, not for narrative. Include materials and their specifications, equipment and settings, procedure, the standards followed, sample size and how it was chosen, and the statistical or analytical treatment. Past tense. If a competent reader in your field cannot repeat the study from this section, it is incomplete.

Results

Report, do not interpret. Each table and figure carries data; the text points out what it shows and refers to it by number. Report the results that went against you as well — selective reporting is an integrity problem, and reviewers notice absent controls.

Discussion

Open by answering the question you set. Then compare your findings against the studies from your introduction, explain anything unexpected, state limitations plainly, and say what follows. Do not introduce new results here.

Abstract, written last

150 to 250 words in one paragraph, or under structured labels where the journal requires them. Write it after the paper is finished, using the numbers that actually appear in the results. It is the only part most readers ever see and the part editors screen on.

Title and keywords

The title should say what was done and found, not tease it. Keywords should be the terms a researcher would type, and should not simply repeat words already in the title — that wastes your indexing.

Submission

Choosing a journal and submitting

Choose the journal before the final formatting pass, because scope decides acceptance more often than quality does. A sound paper sent to the wrong journal is desk-rejected without review.

Match the scope. Read the aims-and-scope statement and check that recent issues actually publish work like yours.
Verify indexing at the source. Match the ISSN against Elsevier’s Scopus Source List or the DOAJ directory. A journal’s own “Scopus indexed” badge is a claim, not evidence.
Check the fee before submitting, not after acceptance. Reputable journals disclose article processing charges openly; many subscription journals charge nothing.
Read the author guidelines properly. Word limits, reference style, figure resolution and section order differ by journal, and ignoring them signals carelessness.
Watch for predatory signals — promised review in days, hidden fees, an unverifiable editorial board, an implausibly broad scope, or an unsolicited flattering invitation.

Our journal finder matches a paper against live journal data and checks indexing against the indexes’ own lists, with fees, timelines and conservative predatory warnings.

The cover letter

Short and specific: what the paper reports, why it fits this journal, that it is original and not under review elsewhere, and any declarations. It is a professional note to an editor, not a summary of the abstract.

Rejection

Why papers get desk-rejected

A desk rejection happens before peer review, usually within days, and is nearly always avoidable:

Out of scope — the single biggest cause, and entirely preventable
Guidelines ignored — over the word limit, wrong reference style, missing sections
No clear contribution — the editor cannot tell what is new
Weak or absent methodology detail — the work cannot be evaluated
Language quality — not fluency for its own sake, but prose an editor has to reread to parse
High similarity — most journals screen on submission
Undeclared AI use — most publishers now require disclosure of AI assistance, and undisclosed use is treated as a breach

Revision

Responding to reviewers

“Major revision” is a good outcome — the journal is still interested. Handle it as a structured document, not an email.

Reproduce every comment and answer each one directly beneath it
State exactly what changed and where, by section and page
Where you disagree, say so politely and with evidence. Reviewers can be wrong, and a reasoned rebuttal is acceptable; ignoring a comment is not
Never leave a point unanswered, even one you consider minor
Keep the tone professional however unfair a comment feels

If the paper is rejected outright, use the reviews. They are free expert criticism, and a paper revised on their basis is usually stronger at the next journal.

Usually 150–250 words in one paragraph — problem, methods, key results and conclusion. Some journals want a structured abstract.

Which citation style should I use?+

Whatever your target journal/department specifies — IEEE (engineering), APA (social science), Vancouver (medicine). Every citation must map to a complete, real reference.

How long should a research paper be?+

Most journal papers run 3,000 to 8,000 words depending on the field and the journal's own limit, which is stated in the author guidelines and should be treated as binding. Conference papers are usually shorter, often 4 to 8 pages in the required template.

What is the IMRaD structure?+

IMRaD stands for Introduction, Methods, Results and Discussion — the standard skeleton of an empirical paper, preceded by an abstract and followed by a conclusion and references. It exists so readers can find any part of a paper quickly without reading it linearly.

Why was my paper desk-rejected without review?+

Most often because it was out of scope for the journal, or because the author guidelines were not followed — word limit, reference style or missing sections. Other frequent causes are no clearly stated contribution, insufficient methodology detail, high similarity on the submission screen, and undeclared AI use.

Do I have to disclose AI use in a research paper?+

Most publishers now require it. The usual rule is that AI cannot be listed as an author, and any substantive assistance must be described in the declarations or acknowledgements. Undisclosed use is treated as a breach of publication ethics, so declare it and keep the research and analysis your own.

How do I choose the right journal for my paper?+

Start with scope: read the aims-and-scope statement and check that recent issues publish work like yours. Then verify indexing against the index's own list rather than the journal's claim, confirm the fee before submitting, and read the author guidelines. Scope decides acceptance more often than quality does.
