Lancet Formatting Requirements
Typography
Lancet manuscripts use 12pt Times New Roman with double line spacing. This applies to the main text, structured abstract, references, and figure legends. Tables may use 10pt. Section headings in the main text are bold without numbering. The Lancet does not use subheadings within the Methods section as extensively as other journals — the narrative is expected to flow clearly within the Methods as a cohesive section. KERNIT applies these typography settings in the Lancet export.
Page Layout
Lancet manuscripts use A4 paper with 2.5cm margins on all sides in a single-column layout. All pages must be numbered. Line numbers are required for peer review. The title page should include the title (maximum 150 characters), author names and affiliations, corresponding author contact details, word count for the main text (excluding abstract, tables, figures, and references), and the number of figures and tables. A separate cover letter is required.
Citations & References
The Lancet uses Vancouver-style superscript citations¹ numbered in the order they first appear in the text. References are listed at the end of the paper in numerical order. Lancet reference format for journal articles: Author AB, Author CD, Author EF, et al. (after six authors). Title. Journal. Year; Volume: pages. For books: Author AB. Title of Book. Edition. Location: Publisher; Year. DOIs are listed at the end of electronic references.
Abstract
Lancet Articles require a structured abstract (Background, Methods, Findings, Interpretation) of up to 250 words. The "Findings" section replaces "Results" in Lancet style. The abstract must include key statistics with confidence intervals for the primary outcome. A "Funding" line appears at the end of the abstract. Correspondence and Comment articles do not require an abstract. Reviews use an unstructured summary of up to 250 words.
Frequently Asked Questions
- What is the difference between The Lancet and Lancet Oncology?
- The Lancet is a general medical journal publishing the highest-impact clinical research across all medical specialties — randomized trials, meta-analyses, and major cohort studies. Lancet Oncology is a specialty journal focused exclusively on cancer prevention, diagnosis, and treatment. The Lancet family also includes Lancet Neurology, Lancet Infectious Diseases, Lancet Psychiatry, Lancet Digital Health, and eClinicalMedicine, among others. Each journal has separate editorial teams and submission systems.
- What are the structured abstract requirements for Lancet Articles?
- Lancet Articles (the primary research format) require a structured abstract with four sections: Background (why the study was done), Methods (what was done and how), Findings (key results with key statistics), and Interpretation (what the results mean). Total abstract word count is 250 words. The Interpretation section should explicitly state the clinical implications. The structured abstract is what most readers see first — it must stand alone without reference to the main text.
- What are Lancet word count limits for different article types?
- Lancet Articles have a main text limit of 4,000 words (excluding abstract, tables, figures, and references). Lancet Correspondence is limited to 400 words with no abstract. Personal View articles are up to 2,500 words. Comment articles are 800–1,200 words. Reviews are up to 8,000 words. These limits apply to The Lancet; specialty Lancet journals may have different limits.
- What are panel boxes in Lancet papers?
- Lancet Papers include one or more "panels" — boxed highlights summarizing key messages. Most Lancet Articles include a "Research in context" panel with two subsections: Evidence before this study (what was known) and Added value of this study (what new knowledge this work contributes). A panel box counts toward the figure/table limit but not the word count. Panels are formatted as separate boxes in the manuscript.
- What statistical reporting standards does The Lancet require?
- The Lancet requires adherence to established reporting guidelines: CONSORT for randomized trials, STROBE for observational studies, PRISMA for systematic reviews and meta-analyses, STARD for diagnostic accuracy studies, and TRIPOD for prediction models. The Lancet Statistics Committee reviews statistical methods. Exact P values should be reported (not P<0.05). Confidence intervals are required for all primary outcomes. Effect sizes must accompany statistical significance tests.
