Page Numbering for Papers and Contracts: Position, Format, and Start Page

Scans without page numbers, merged files with jumbled numbering, covers that shouldn't be numbered... Adding page numbers is one of the most common steps in document standardization. Mastering proper page number settings makes your documents look more professional.

Bottom line: Centered page numbers are the most versatile; dark gray is softer than pure black; set the start page to 0 so the cover has no number and the body starts at 1.

Choosing Page Number Position

Center

The most versatile choice

The standard for formal documents like papers, reports, and proposals. Visually balanced, and won't be covered by either hand when flipping pages.

Left

Great for books and manuals

In traditional publishing, odd pages have numbers at the bottom right and even pages at the bottom left. If you need a single position, bottom left works well for left-bound documents.

Right

Best for single-page viewing

Bottom right is the most noticeable position when reading on screen. Ideal for presentations and single-page PDFs meant primarily for digital viewing.

Note: Keep at least 15-20mm of margin between the page number and the bottom edge to avoid clipping when printing.

Flexible Start Page Settings

Start at 1 (default): Every page gets a number, with the first page showing 1. Best for short documents without a cover.
Start at 0: The first page shows 0, useful when the cover needs a number but you don't want to start at 1.
Skip cover: With "Skip first page" checked, the cover gets no number and the second page shows 1. This is the standard for theses and proposals.
Start from any number: For contract continuations or multi-volume publications, the second file can continue numbering from where the first one ended.

Color and Font Size Recommendations

Color

We recommend dark gray (#333333) instead of pure black (#000000). Pure black page numbers can be too jarring against body text, while dark gray is softer and won't distract readers from the content.

Font Size

12px is the standard for most documents. For presentation slides meant to be projected, increase to 14-16px for better visibility at a distance. For documents with 10.5pt (about 14px) body text, 12px page numbers provide good visual proportion.

Page Number Strategies by Scenario

Graduation thesis: No page number on cover, Roman numerals (i, ii, iii) for the table of contents, body starts at 1. Requires processing different sections separately.
Business contract: Centered, 12px, dark gray, skip cover. Page numbers make it easy for both parties to reference specific clauses by phone or email.
Electronic bid: Bottom right, 12px, black, no pages skipped. Bidding systems usually require continuous page numbers on every page.
Product manual: Centered or bottom right, 10-12px, color can be adjusted to match brand guidelines.
