Tips for page numbers that look right
Page numbers are what people use to find their way round a document, so they’re worth getting right.
- Number the final versionNumbers are stamped onto the pages themselves, so add them last, once pages have been added, removed and put in order. Deleting or moving a page afterwards leaves the numbering out of step.
- Use Page 1 of N for printoutsWhen a document is printed and handed round, “Page 1 of N” shows at a glance whether a page has gone missing. For documents read on screen, plain numbers look tidier.
- Keep clear of existing footersNumbers go about 1 cm from the edge. If your pages already have a footer or a logo there, put the numbers at the top instead, so the two don’t overlap.
- Continuing another document?Set “Start at” to carry on the count. If part one ended on page 24, start part two at 25, and the two files read as one numbered set.
Like every Altto tool, this runs on your device — nothing you add is uploaded. How Altto works
is the size the numbers are printed at, the same size Word uses for footnotes, so they’re easy to read without crowding the page.
