Formatting Fixes That Matter
By Dr. Zubair Khalid, DVM, MS, PhD ·
Quick Answer
- Review the journal's specific formatting instructions before submission because each journal applies different reference styles, figure requirements, and line-numbering rules.
- Build a verification checklist that covers reference accuracy, figure resolution, and line numbering to reduce the chance of technical rejection or resubmission delays.
- Formatting compliance does not guarantee acceptance, and editors may still request substantive revisions after technical checks pass.
Understanding Why Formatting Compliance Matters
Journal formatting requirements exist for practical reasons that affect the efficiency of peer review and publication. When authors follow the stated formatting rules, editors can move manuscripts into review faster, reviewers can navigate the text more easily, and production staff can prepare accepted papers without unnecessary back-and-forth. The Committee on Publication Ethics Core Practices describe the responsibilities that journals and authors share in maintaining the integrity of the publication process. While formatting is not the same as research integrity, it is part of the professional conduct that supports smooth editorial workflows.
Editors routinely see manuscripts that contain strong science but fail on basic formatting requirements. These failures do not necessarily reflect the quality of the research, but they do create extra work for editorial staff and reviewers. A manuscript with missing line numbers, low-resolution figures, or an inconsistent reference list forces the editor to spend time on administrative corrections instead of focusing on the scientific content. In a competitive submission environment, that friction can slow down the decision process.
The practical goal is to make the manuscript as easy as possible for the editor and reviewers to read and evaluate. Formatting compliance signals that the author has read the journal's instructions and respects the journal's workflow. It also reduces the chance of a technical rejection that delays the scientific contribution from reaching the community.
Understanding Journal Instructions
Where to Find the Author Guidelines
Every journal publishes its instructions for authors in a distinct location. Most journals place these instructions on their official website under a heading such as "Instructions for Authors," "Author Guidelines," or "Submission Guidelines." Some journals also include formatting requirements in the submission system itself, so the author may see the rules again when uploading files.
The National Library of Medicine Bookshelf provides access to authoritative biomedical texts that describe research methods and publication practices. While the Bookshelf is not a journal instruction page, it serves as a gateway to the standards that many biomedical journals expect authors to follow. Authors who are new to a field can use such resources to understand the conventions that journals in that field typically adopt.
What the Instructions Typically Cover
Journal instructions usually cover the same categories of requirements, although the specific details vary. The most common categories include manuscript structure, reference style, figure specifications, table formatting, line numbering, word limits, and disclosure statements. Some journals also require a specific title page format, a conflict of interest statement, or a data availability statement.
The EQUATOR Network maintains a collection of reporting guidelines that help authors structure their manuscripts according to the standards of their research type. For example, a randomized trial has different reporting requirements than a qualitative study or an animal experiment. The EQUATOR Network helps authors to identify which reporting guideline applies to their study design and to follow it during manuscript preparation. This is a separate step from the journal's formatting instructions, but both matter for a successful submission.
How to Interpret Ambiguous Instructions
Journal instructions are not always perfectly clear. Some journals use vague language such as "standard formatting" or "usual style" without specifying what that means. When the instructions are ambiguous, the author should look at recently published articles in that journal to see how the formatting appears in practice. Published papers show the reference style, figure layout, and heading structure that the journal actually uses.
If the published articles do not resolve the ambiguity, the author can contact the editorial office with a specific question. A concise email that asks about one or two formatting points is usually welcome. The author should not ask questions that the instructions already answer clearly, because that creates unnecessary work for the editorial staff.
Building a Formatting Compliance Checklist
Reference Style Verification
The reference list is one of the most common sources of formatting problems. Journals use different reference styles, including numbered styles, author-date styles, and variations within each category. The journal's instructions will specify the style, but the author must also check the details of that style, such as how many authors are listed before "et al." is used, whether article titles are capitalized, and how journal names are abbreviated.
The National Library of Medicine Bookshelf includes the official NLM style guide, which many biomedical journals use as the basis for their reference requirements. Authors who are submitting to a journal that follows NLM style can consult the Bookshelf to verify the correct format for each reference type. The key is to match the journal's stated style, not to assume that one style works for all journals.
A practical approach is to check every reference against the journal's stated style and against the original source. This means verifying the author names, the year, the article title, the journal name, the volume, the issue, and the page numbers. A reference that is correct in the author's own citation manager may still be wrong if the journal requires a different format.
Figure Resolution and File Format
Figures are another common source of formatting problems. Journals specify minimum resolution requirements, usually in dots per inch or pixels per inch. The journal also specifies the acceptable file formats, such as TIFF, EPS, or PDF. The author must prepare figures that meet the resolution requirement at the final printed size, not at the size the figure appears on the computer screen.
The National Institutes of Health Grants and Funding pages describe the expectations for figures and other materials in grant applications, and these expectations often mirror what journals require. The principle is the same: the figure must be clear enough for the reader to see the details that support the scientific claim. A figure that looks fine on a monitor may be too low resolution for print or for the journal's online viewer.
The author should also check whether the journal requires figures to be embedded in the manuscript or uploaded as separate files. Some journals want the figures in the text at the point of citation, while others want them at the end of the manuscript or as separate files. The instructions will specify the preferred arrangement.
Line Numbering and Manuscript Structure
Line numbering is a simple requirement that many authors overlook. Journals use line numbers so that reviewers and editors can refer to specific lines in their comments. The journal may require continuous line numbering throughout the manuscript, or it may require numbering to restart on each page. The instructions will specify the preferred method.
The manuscript structure also matters. Most journals require a specific order for the sections, such as title page, abstract, introduction, methods, results, discussion, and references. Some journals also require a separate acknowledgments section or a conflict of interest statement. The author should follow the journal's structure exactly, even if the author prefers a different organization.
At a Glance
| Formatting Element | Common Journal Requirement | Verification Method | Typical Failure Mode |
|---|---|---|---|
| Reference style | Specific style such as NLM, APA, or Vancouver | Compare each reference against the journal's stated style and published examples | Mixed styles from copying references from other papers |
| Figure resolution | Minimum resolution at final print size | Check the pixel dimensions and resolution in the image file | Low-resolution images that look fine on screen but blurry in print |
| Line numbers | Continuous or per-page numbering | Open the manuscript and confirm the numbers appear correctly | Missing line numbers or numbering that restarts incorrectly |
| Manuscript structure | Specific section order and headings | Compare the manuscript against the journal's instructions | Sections in the wrong order or missing required sections |
| File format | Specific file types for text and figures | Check the file extension and the journal's accepted formats | Submitting a file format that the journal does not accept |
Practical Steps for Formatting Compliance
Step 1: Read the Instructions Before Writing
The formatting requirements should be reviewed before the manuscript is written, not after. When the author knows the journal's structure and style requirements in advance, the manuscript can be written to match those requirements from the start. This avoids the need to reformat the entire manuscript after the writing is complete.
The author should read the instructions carefully and highlight the formatting requirements that are specific to the journal. Some requirements are common across journals, but the details often differ. The author should note the reference style, the figure requirements, the line numbering rule, and the manuscript structure.
Step 2: Use the Journal's Template if Available
Many journals provide a manuscript template that already includes the correct structure, heading styles, and reference formatting. The template is a useful starting point because it reduces the risk of missing a formatting requirement. The author should download the template from the journal's website and write the manuscript directly into the template.
If the journal does not provide a template, the author can use a published article from the journal as a model. The published article shows the actual formatting that the journal uses, including the heading style, the reference format, and the figure layout. The author should match the published article's formatting as closely as possible.
Step 3: Verify the Reference List
The reference list should be checked after the manuscript is written and before submission. The author should verify that every reference in the text appears in the reference list, and that every reference in the list is cited in the text. The author should also verify that the reference format matches the journal's style.
The National Library of Medicine Bookshelf provides the standard reference formats for biomedical journals. The author can use the Bookshelf to check the correct format for journal articles, books, book chapters, and other reference types. The key is to match the journal's stated style, not to assume that the Bookshelf format applies to every journal.
Step 4: Check the Figures
The figures should be checked for resolution, file format, and placement. The author should open each figure file and check the resolution at the final print size. The journal's instructions will specify the minimum resolution, and the author should ensure that the figure meets that requirement.
The author should also check that the figure file format is acceptable to the journal. Some journals accept only certain file formats, and the author should convert the figure to the required format if necessary. The figure should also be placed in the manuscript according to the journal's instructions, either embedded in the text or placed at the end.
Step 5: Run a Final Compliance Check
The final compliance check should be done immediately before submission. The author should go through the journal's instructions point by point and verify that the manuscript meets each requirement. This check should include the reference style, the figure resolution, the line numbering, the manuscript structure, and the file formats.
The author should also check the manuscript for common errors, such as missing page numbers, inconsistent heading styles, or references that are not cited. The final check is the last opportunity to catch formatting problems before the manuscript goes to the editor.
Common Formatting Failure Patterns
The Mixed Reference Style Problem
A common failure pattern is the mixed reference style. Authors often copy references from other papers or from citation databases, and these references may be in different styles. The result is a reference list that mixes styles, with some references in one format and others in another format. This is immediately visible to the editor and creates a poor impression.
The fix is to check every reference against the journal's style and to reformat any reference that does not match. The author should not assume that a reference copied from another paper is in the correct style. The reference must be checked against the journal's instructions.
The Low-Resolution Figure Problem
Another common failure is the low-resolution figure. Authors often prepare figures on a computer screen and do not check the resolution at the final print size. The figure may look clear on the monitor but be too low-resolution for the journal's requirements. The editor may reject the manuscript or ask for the figure to be replaced.
The fix is to check the figure resolution before submission. The author should open the figure file and verify the resolution at the final print size. If the resolution is too low, the author should regenerate the figure at a higher resolution or use a different file format.
The Missing Line Number Problem
The missing line number problem is simple but common. The author writes the manuscript without line numbers, or the line numbers are not continuous, or the line numbers restart incorrectly. The editor needs line numbers to refer to specific lines in the manuscript, and the absence of line numbers creates a problem.
The fix is to add line numbers to the manuscript before submission. The author should check the journal's instructions for the preferred line numbering method and apply it to the manuscript. The line numbers should be visible in the manuscript file that is submitted.
The Incorrect Manuscript Structure Problem
The incorrect manuscript structure is another common failure. The author may write the manuscript in a structure that is different from the journal's requirements. The journal may require a specific section order, or the journal may require sections that the author has not included.
The fix is to compare the manuscript structure against the journal's instructions. The author should check the section order and the required sections, and make any necessary changes before submission. The manuscript structure should match the journal's requirements exactly.
The Role of Reporting Guidelines
Selecting the Right Reporting Guideline
Reporting guidelines are a separate set of requirements that apply to the content of the manuscript, not the formatting. The EQUATOR Network provides a collection of reporting guidelines for different study types. The author should identify the reporting guideline that applies to the study design and follow it during manuscript preparation.
For example, a randomized controlled trial should follow the CONSORT guideline, a systematic review should follow the PRISMA guideline, and a qualitative study should follow the SRQR guideline. The reporting guideline specifies the information that should be included in the manuscript, such as the study design, the participants, the intervention, and the outcomes. Following the reporting guideline helps the author to write a complete and transparent manuscript.
How Reporting Guidelines Interact with Formatting
The reporting guideline and the journal's formatting instructions are separate but related. The reporting guideline specifies the content that should be included in the manuscript, while the journal's formatting instructions specify how the manuscript should be presented. The author must follow both sets of requirements.
The author should use the reporting guideline to structure the content of the manuscript, and then use the journal's formatting instructions to format the manuscript. The reporting guideline may specify the information that should be included in each section, and the journal's formatting instructions may specify the heading style and the reference format. The author must follow both sets of requirements to produce a complete manuscript.
Data Management and Sharing Considerations
The Data Availability Statement
Many journals require a data availability statement that explains where the data supporting the manuscript can be found. The National Institutes of Health Data Management and Sharing Policy describes the expectations for data management and sharing in NIH-funded research. The policy requires researchers to submit a data management and sharing plan with their grant application and to follow the plan during the research.
The journal's data availability statement is a separate requirement from the NIH policy. The journal may require the author to state whether the data are available and where they can be found. The author should check the journal's instructions for the data availability statement and provide the required information.
The Data Management Plan
The NIH Data Management and Sharing Policy applies to NIH-funded research, and it requires a data management and sharing plan. The plan describes how the data will be managed and shared, including the data types, the data standards, the data repository, and the timeline for sharing. The plan is submitted with the grant application and is reviewed as part of the application.
The author should be aware of the NIH policy if the research is NIH-funded. The policy is separate from the journal's formatting requirements, but the author may need to include a data availability statement in the manuscript that is consistent with the NIH plan. The author should check the journal's instructions and the NIH policy to ensure that the data availability statement is consistent with both.
Author Identity and ORCID
The ORCID Identifier
The ORCID identifier is a unique identifier for researchers that distinguishes them from other researchers with similar names. The ORCID for Researchers page describes how researchers can create an ORCID record and use it to connect their research activities. Many journals require an ORCID identifier for the corresponding author, and some journals require it for all authors.
The author should create an ORCID record if they do not already have one. The ORCID record should be kept up to date with the author's affiliations, publications, and other research activities. The author should include the ORCID identifier in the manuscript submission, as required by the journal.
The ORCID Record Maintenance
The ORCID record should be maintained throughout the author's career. The author should add new publications to the ORCID record, update the affiliation when it changes, and verify that the record is accurate. The ORCID record is a public record of the author's research activities, and it should be kept current.
The author should also check that the ORCID identifier is correctly included in the manuscript. The identifier should be formatted according to the journal's instructions, and it should be placed in the correct location in the manuscript. The author should verify the identifier before submission to avoid a formatting problem.
Publication Ethics and Authorship
Authorship Requirements
The Committee on Publication Ethics Core Practices describe the standards for authorship and other publication ethics issues. The core practices state that all authors should have made a significant contribution to the work and should be accountable for the content. The journal's instructions may specify the authorship criteria and the requirements for the author list.
The author should ensure that the author list is correct and that all authors meet the journal's authorship criteria. The author should also ensure that the order of authors is agreed upon by all authors. The author list should be finalized before submission, and any changes after submission should be handled according to the journal's instructions.
Conflict of Interest
The conflict of interest statement is a required part of many manuscripts. The author should disclose any financial or personal relationships that could be seen as influencing the research. The journal's instructions will specify the format for the conflict of interest statement.
The author should be transparent about any potential conflicts of interest. The conflict of interest statement should be included in the manuscript in the location specified by the journal. The author should also ensure that the statement is consistent with the information provided in the submission system.
Responding to Peer Review Comments
The Reviewer Response Letter
The peer review process often results in a request for revisions. The author must respond to the reviewer comments with a response letter that addresses each comment. The response letter should be structured to make it easy for the reviewer to see how each comment was addressed.
The response letter should list each reviewer comment and the author's response to that comment. The author should explain what was changed in the manuscript and where the change was made. The author should also explain if a comment was not addressed and why. The response letter should be clear and respectful.
The Manuscript Revision
The manuscript revision should be prepared according to the journal's instructions. The journal may require a marked version that shows the changes, or it may require a clean version. The author should check the journal's instructions for the revision format and follow the instructions.
The author should also check the formatting requirements for the revised manuscript. The formatting requirements may be the same as the original submission, or the journal may have additional requirements for the revision. The author should verify the formatting before submitting the revision.
The Revision Timeline
The journal will specify a timeline for the revision. The author should submit the revision within the specified timeline, and the author should request an extension if the timeline cannot be met. The author should also ensure that the revision is complete and that all reviewer comments have been addressed.
The author should also check the formatting of the revised manuscript before submission. The revision should meet the same formatting requirements as the original submission, and the author should verify the formatting before submitting the revision.
Common Failure Patterns in the Revision Process
The Incomplete Response Letter
A common failure in the revision process is the incomplete response letter. The author may address some reviewer comments but not others, or the author may not explain the changes clearly. The reviewer may be unable to see how the comments were addressed, and the manuscript may be sent back for further revision.
The fix is to address every reviewer comment in the response letter. The author should list each comment and provide a clear response. The author should also indicate where the change was made in the manuscript. The response letter should be complete and clear.
The Unaddressed Formatting Requirement
Another common failure is the unaddressed formatting requirement. The author may focus on the scientific content of the revision and overlook the formatting requirements. The journal may require a specific format for the revised manuscript, and the author may not follow the format.
The fix is to check the journal's instructions for the revision format before submitting the revised manuscript. The author should verify the formatting requirements and ensure that the revised manuscript meets them. The author should also check the response letter for completeness.
The Late Submission
The late submission is a common failure in the revision process. The author may not submit the revision within the specified timeline, and the journal may consider the manuscript withdrawn. The author should submit the revision within the timeline or request an extension before the deadline.
The fix is to plan the revision timeline and to submit the revision before the deadline. The author should also check the journal's instructions for the revision timeline and the extension policy. The author should request an extension if the timeline cannot be met.
Limitations of Formatting Compliance
Formatting compliance is a necessary step in the publication process, but it does not guarantee acceptance. The manuscript must also have sound science, clear writing, and a meaningful contribution to the field. The formatting is a prerequisite for the review process, but it is not a substitute for the scientific content.
The author should also be aware that the journal's instructions may change over time. The author should check the journal's website for the current instructions before submission. The instructions may be updated, and the author should follow the current version.
The author should also be aware that the formatting requirements may vary by journal. The author should not assume that the formatting requirements for one journal apply to another journal. The author should check the instructions for each journal before submission.
Professional Escalation Criteria
The author should seek professional help if the formatting requirements are unclear or if the author is unable to meet the requirements. The editorial office can answer questions about the formatting requirements, and the author should contact the editorial office if the instructions are ambiguous.
The author should also seek help if the manuscript has been rejected for formatting reasons. The author should review the rejection letter and identify the formatting problems. The author should then correct the problems and resubmit the manuscript to the same journal or to another journal.
The author should also seek help if the author is unsure about the reporting guideline that applies to the study. The EQUATOR Network provides a list of reporting guidelines, and the author can use the network to identify the appropriate guideline. The author can also consult a colleague or a mentor for guidance.
Frequently Asked Questions
How do I know which reference style my journal requires?
Check the journal's instructions for authors on the journal's website. The instructions will specify the reference style, and the author should follow that style. If the instructions are unclear, look at a published article in the journal to see the reference style in practice.
What is the minimum figure resolution for journal submission?
The minimum figure resolution is specified in the journal's instructions for authors. The resolution is usually given in pixels per inch or dots per inch at the final print size. Check the instructions and prepare the figure to meet the requirement.
Why does my journal require line numbers in the manuscript?
