Reactive Resume has three page formats: A4, Letter, and Free-Form. The format you pick changes how your resume is rendered and exported as a PDF.

Available formats

A4

A4 is the international standard paper size used in most countries outside North America. When you select A4, your resume pages conform to these dimensions: Choose A4 if you’re applying to jobs internationally or in regions that use the metric system.

Letter

Letter is the standard paper size in the United States and Canada. When you select Letter, your resume pages conform to these dimensions: Choose Letter if you’re applying to jobs in North America.

Free-Form

Free-Form is built for resumes that are only read on a screen. Instead of matching a physical page size, it produces a single continuous page with no height limit. The width matches A4 (210mm), and the height extends to fit all your content.
With Free-Form, there are no page breaks. Your resume renders as one continuous document, no matter how much content you have.

Why Free-Form exists

Most resumes are never printed. Yours is almost always read digitally: on a screen, in an applicant tracking system (ATS), or by an AI screening tool. When your resume is processed digitally:
  • ATS parsers extract the text regardless of page dimensions
  • AI scanners analyze the full document as a single unit
  • Recruiters scroll through PDFs on their screens rather than printing them
  • PDF parsing tools read the whole file regardless of page height
Since physical page limits no longer apply in those cases, Free-Form lets you focus on the content instead of fitting it into a fixed page height.
If you don’t plan on printing your resume, Free-Form is usually the simplest choice. Nothing overflows, and there are no awkward page breaks.

Review the preview

Your resume preview updates immediately to reflect the new format. Check that your content displays correctly.

Choosing the right format

If you switch from Free-Form to A4 or Letter, your content is split across multiple pages. Review the result and check that the page breaks don’t fall in awkward places.

Frequently asked questions

Yes. An ATS parses the text in your PDF, not the page dimensions. Free-Form resumes work with applicant tracking systems.
Yes. You can change the format at any time from the Page section in the right sidebar. Your content is preserved. Only the layout changes.
If the employer asks for a one-page resume and expects a traditional format, use A4 or Letter and fit your content on a single page. See Fitting content on a page for tips.
Slightly. A longer single page may produce a marginally larger PDF than a paginated version of the same content, but the difference is negligible for typical resume lengths.
LinkedIn doesn’t display uploaded resumes in their original format; it extracts the content. Free-Form works fine for LinkedIn uploads.
