Number a PDF's pages without fighting the front matter

Page numbers matter as soon as a document is discussed rather than just read. "See page 34" only works if everyone is counting the same way, and a professionally assembled pack that starts its numbering on the cover reads as careless.

Number last

The most important rule has nothing to do with settings. Printed page numbers are drawn onto the page as content. They are not a live field, and they do not recalculate.

So if you number a document and then reorder, insert, or delete pages, the printed numbers are wrong and there is no automatic fix — you have to remove and reapply them. Finish the structural work with the page organiser first, as described in the page management guide, then number the finished article.

Set the start offset

Almost every real document has front matter that should not count: a cover, a title page, a table of contents, sometimes a legal notice.

The page numbering tool lets you choose which physical page receives the number one and where numbering begins to appear. Two settings that sound the same and are not:

• Where numbering starts appearing. Page 3 might be the first page that shows a number at all.
• What number it shows. That page might legitimately be labelled 1, because the cover and contents are not counted.

Getting these to agree is what makes a document feel properly produced. The common failure is a pack where the contents page says a section starts on page 12 and the printed 12 lands three pages away, because one count included the front matter and the other did not.

Decide your convention before you start:

Document type	Usual convention
Report with cover and contents	Numbering starts on the first content page as 1
Legal or regulatory bundle	Every physical page numbered from 1, including the cover
Book-style document	Roman numerals for front matter, arabic from chapter one
Simple internal handout	Number everything; do not overthink it

Choose a position that survives the real world

Bottom centre is the safest default. It is where readers look, it avoids the gutter on both left and right pages, and it is unaffected by whether the document is printed single or double sided.

Bottom outer corner looks more polished for double-sided documents but requires alternating position on odd and even pages. If the tool does not mirror the position, a fixed right-hand number ends up in the binding on every second sheet.

Whatever you choose, leave margin. At least 12 millimetres from the page edge, because:

• most printers cannot print to the physical edge and will clip closer numbers
• binding, stapling, and hole punching eat into the margin
• a number sitting tight against the edge looks like a mistake even when it prints

Also check that the position is empty on every page. A number placed neatly in the footer of the body pages can land on top of a full-bleed chart or an image on one page in the middle.

Format choices

Keep the typography quiet. A neutral sans-serif at 9 to 11 points in dark grey or black reads as production furniture rather than content. Numbers larger than the body text look like an error.

Formats worth considering:

• 7 — clean and sufficient for most documents.
• Page 7 — clearer in packs that will be discussed aloud or over a call.
• 7 of 42 — genuinely useful for anything printed and handed out, because a reader immediately knows whether a page is missing.
• A-7 — section prefixes for multi-part bundles where each annex is numbered independently.

When you need more than a number

If the requirement includes a document title, a date, a filename, a classification, or a case reference alongside the number, use the header and footer tool instead. It handles page variables together with fixed text, which means one pass rather than two overlapping ones, and it keeps everything aligned on the same baseline.

Finally, reopen the exported file and check three pages: the first numbered page, one in the middle, and the last. That thirty-second check catches offset errors, clipped margins, and collisions with content, which is every mistake this task can produce.
