A Practical Checklist Before Submitting Your Research Paper to a Journal

Start with the single question every editor asks: is this a fit?

Before any file fiddling, decide whether the paper belongs at the target journal. The quickest way to waste time is to send a manuscript that misaligns with scope, audience, or methodological standards. Scan recent issues, read the journal’s “Aims and scope” and match your central contribution (not every ancillary result) to what the journal publishes.

Pre-submission checklist: the essentials to finish first

• Confirm journal fit and recent similar articles.
• Use the journal’s current author guidelines for formatting, word counts and section order.
• Complete all required ethical approvals, consent statements and clinical trial registrations.
• Prepare a brief, focussed cover letter that explains novelty, journal fit and suggested/declined reviewers.
• Check citation style and accuracy against the journal’s reference format.
• Ensure figures and tables meet resolution and file-type rules; label files clearly.
• Create a clean submission-ready file set: main manuscript, figures, tables, supplementary materials, and any required forms.

Cover letter and title: make them work for the editor

Your cover letter should be short (one page), specific and persuasive. State the article type, what is new, and why it belongs in that journal. If the journal asks for suggested or excluded reviewers, provide names with short affiliations and, where helpful, a brief reason for each suggestion (expertise or lack of conflict).

Title and abstract should reflect the manuscript you are submitting—no overreach. A precise title and a structured abstract that mirrors the paper’s aims and conclusions make the editor’s screening faster and reduce the risk of a desk rejection.

Manuscript file: one clean, readable document

Format the main manuscript to the journal’s template if required; if not, use a clean, single-column layout, consistent headings, and numbered lines where requested. Include an accurate running title, all author affiliations and ORCID iDs if required.

Small but critical checks:

• Spell-check for British vs American English as specified.
• Confirm all in-text citations appear in the reference list and vice versa.
• Run one final read for clarity—could a colleague in another subfield follow the main argument?

Figures, images and tables: technical and ethical checks

Check each figure for resolution, preferred file format (often TIFF for images, EPS for vector graphics), readable axis labels and embedded legends where the journal requires them. Avoid last-minute downsampling—if an image appears pixelated when zoomed to 100%, regenerate it at higher resolution.

Label figure panels consistently (A, B, C) and ensure scale bars are present for micrographs. For composite images, prepare original, unprocessed data files in case reviewers request them; most journals will ask for raw images if integrity questions arise.

References and citation formatting: don’t give editors extra work

Use a reference manager to apply the journal’s style and fix common problems: missing DOIs, incomplete page ranges, incorrect author order and inconsistent journal abbreviations. If journal policy requires PubMed IDs or DOIs in references, include them.

If you want a deep technical check, follow our guide on reference formatting before submission for a systematic pass-through.

How to format references before submitting your paper

Ethics, data availability and supplementary files

Confirm you have documented IRB or ethics committee approvals, participant consent statements and trial registry numbers where applicable. Prepare a Data Availability Statement that matches journal policy: named repository plus accession or DOI, or a clear reason why data cannot be shared.

For supplementary materials, name files clearly (e.g., “Supplementary_Table_1.xlsx”) and include a short readme describing file contents. Compress large datasets into standard archive formats if allowed.

Authorship, contributions and conflicts of interest

Make sure the author list, order and corresponding author are final. Many journals ask for a contributor statement (who did conceptualization, analysis, writing). Circulate the final submission package to all co-authors and get explicit approval via email or signed statement if required.

Declare funding sources and conflicts of interest exactly as the journal requires—undisclosed conflicts discovered later can lead to retraction.

Before uploading, check file naming and acceptable file types. Example naming convention: JournalSurname_Manuscript_v1.pdf for the main file and JournalSurname_Fig1.tif for figures. Verify that the combined PDF renders correctly (no missing fonts or odd characters) and that embedded hyperlinks in the manuscript point to persistent sources (DOIs) rather than personal file paths.
