How to Add Page Numbers to a PDF (Including Skipping the Cover)

Numbering sounds trivial until you hit the cover page problem: should it count, should it show, and are those the same question? They are not.

Page numbers are what allow someone to say 'the third paragraph on page nine' instead of scrolling and hoping. Courts require them, universities require them, and any document assembled from several sources almost never arrives with them.

The cover page question

Almost every document runs into this. There is a cover, and the question is whether it counts. In publishing convention the cover is page one but carries no printed number, so the page after it is visibly numbered 2. In plenty of business documents the cover is outside the count entirely, and the first content page is numbered 1.

These are two different settings, and conflating them is why numbering goes wrong. One controls which page gets the first printed number. The other controls what that number is. Keep them separate and either convention is a few seconds of work.

💡

For a document with a cover and a contents page, a common setup is to start stamping on page 3 and to start the count at 1, so the body reads naturally from 1.

Choosing a position

Bottom centre is the default for a reason: it reads naturally, it survives being printed double-sided, and it rarely collides with anything. Bottom right suits single-sided documents that get flicked through by the corner. Top positions are best avoided when the pages already carry a header, which most formal documents do.

Whatever you choose, check the margin. A number too close to the edge risks being clipped by a printer that cannot reach the boundary, and one too far in starts competing with the text.

Format

A plain number is right for most documents. 'Page 4' is friendlier in a report that will be read casually. The 'of' formats — 4 of 18 — earn their place in printed documents that might be dropped or photocopied, because a reader can tell at a glance whether pages are missing. Legal bundles and tender submissions frequently require exactly that.

Finish assembling first

Number last. Merging or reordering after numbering leaves the printed numbers out of sequence.

Decide what counts and what shows

Which page gets stamped first, and what number that page carries.

Pick position, size and margin

Check a preview so the number does not land on existing content.

Save and check the joins

Look at the first numbered page and the last one — that catches almost every mistake.

Numbers already in the document

If the document already has printed numbers from whatever created it, adding more gives you two competing sets. Existing numbers are part of the page content and cannot be stripped out by a numbering tool. Either position the new ones somewhere the old ones are not, or go back and re-export from the source document.

This is another argument for numbering as the final step. A merged document usually carries fragments of numbering from each source, and stamping a single consistent sequence over the top is what makes it read as one document.

Mixed page sizes

Documents assembled from several sources often contain a mixture of A4, Letter and the odd landscape sheet. A tool that assumes one page size will put the number in a different place on each. Measuring every page individually keeps the number the same distance from the edge throughout, which is what a reader expects.
