Printing an EPUB as PDF: Fonts, Margins, and Page Size
Printing an EPUB starts with three choices this tool makes for you: page size, margins, and which font actually renders the text. This guide explains exactly what each one does.

Page size
Letter or A4, selectable before converting.
Margins and indentation
A fixed roughly 0.75 inch page margin applies throughout. Any CSS margin-left, padding-left, or margin declared on a paragraph in the EPUB’s own stylesheet becomes extra left indentation, clamped to a maximum so a malformed stylesheet can’t break the page layout.
Fonts in the output PDF
The PDF embeds a bundled Unicode font family — regular, bold, italic, and bold-italic — rather than any font the EPUB itself declares or embeds. The EPUB’s own font-weight and font-style CSS select which of those four styles renders each run of text, but a specific font-family the EPUB requests is not applied.
Font size handling
A font-size declared in px, pt, em, rem, or percent is resolved to an absolute PDF point size relative to its inherited size, clamped to a sane range so an extreme declared value can’t produce unreadable or broken output.
EPUB to PDF: Fonts and Page Size FAQ
- Can I pick a different font for the output?
- No — the tool always uses its bundled Unicode font, in whichever weight and style the EPUB’s own CSS requests (regular, bold, italic, or bold-italic).
- Why doesn’t my book’s custom font show up in the PDF?
- Custom font embedding from the EPUB is intentionally out of scope — the output always uses the bundled font family instead.
- What page sizes are supported?
- Letter and A4.
- Does the converter respect text alignment from the EPUB?
- Yes — left, right, and center alignment declared in the EPUB’s CSS are applied.
- What happens with an extremely large declared font size?
- It’s clamped to a sane maximum rather than producing broken or unreadable pages.
