The wrong font makes a professionally edited book look amateur. The right font is invisible — readers never notice it, they just feel comfortable reading. This guide covers the best fonts for every KDP genre, the sizes that work, and what to avoid. Use the free font checker tool below to preview any font on a realistic book page before you commit.
Select a font, adjust the size, and see exactly how your book interior will look in print. The preview below renders on a white background exactly as your printed page will appear — not on a dark screen.
The morning had barely broken when Sarah realised the envelope on her doorstep was addressed in her own handwriting — dated three years from now. She turned it over twice, examining the postmark, the slight tremor in the lettering. The street was empty. A single crow watched from the oak tree at the end of the lane. She had two choices: open it, or go back inside and pretend she had never seen it at all.
She had been here before, in a manner of speaking. Not with letters. But with choices that arrived before she was ready for them. The crow had not moved. Neither had she. The morning light was the colour of old paper, and the envelope felt heavier than it should have.

Font choice in book design is one of those decisions that readers never consciously notice when done correctly — and immediately feel when done wrong. No reader sits down with a paperback and thinks “excellent Garamond choice.” But readers do put down books they find tiring to read, and they often cannot explain why. Very often, the answer is typography.
The practical stakes for KDP authors are real. A book formatted in Arial or Calibri — the default fonts in Microsoft Word and Google Docs — looks like a printed document, not a published book. The visual signal tells experienced readers before they read a single sentence that this is an amateur production. A book formatted in Garamond at 11pt with appropriate leading and margins looks like it came from a publishing house. That visual credibility influences whether a reader trusts the content.
Body text is the font your readers spend 99% of their time looking at. It needs to disappear into the reading experience rather than call attention to itself. These are the fonts that accomplish this most reliably for KDP print books.
Your chapter heading font is the only place in your book where you can afford to be slightly more expressive. It appears briefly — readers see it for a second at the top of each chapter, then move on to the body text. This means you can choose a slightly more distinctive font for headings without compromising reading comfort.
The golden rule: your heading font and body font must pair well together. The most reliable approach is to use either the same font at a larger size, or a complementary font from the same family. Mixing Garamond body text with a geometric sans-serif heading often looks jarring in print unless executed very intentionally.
| Heading Font | Pairs Well With | Style | Best For |
|---|---|---|---|
| Garamond Bold / EB Garamond Bold | EB Garamond (body) | Classic | Literary fiction, memoir |
| Playfair Display | Lora, EB Garamond, Crimson | Elegant | Romance, historical, literary |
| Palatino Bold | Palatino (body) | Traditional | All genres — very safe choice |
| Libre Baskerville Bold | Libre Baskerville (body) | Strong | Thriller, mystery, non-fiction |
| Cormorant Garamond | EB Garamond, Crimson Text | Refined | Literary, historical, poetry |
| Georgia Bold | Georgia (body) | Modern classic | Non-fiction, business |
Different genres have different visual conventions that readers unconsciously expect. A cozy mystery with Garamond reads as legitimate. The same book set in a clean sans-serif reads as a report. Matching your font to your genre is as much about meeting reader expectations as it is about aesthetic preference.
| Genre | Primary Pick | Alternative | Avoid |
|---|---|---|---|
| Literary Fiction | EB Garamond 11pt | Cormorant Garamond | Calibri, Arial |
| Commercial Fiction / Thriller | Palatino 11pt | Libre Baskerville | Times New Roman 12pt |
| Romance | Lora 11pt | Crimson Text | Times New Roman |
| Fantasy / Sci-Fi | Palatino 11pt | EB Garamond, Georgia | Comic Sans, decorative fonts |
| Cozy Mystery | EB Garamond 11pt | Georgia 11pt | Courier, sans-serif |
| Non-Fiction / Self-Help | Georgia 11pt | Merriweather 10.5pt | Times New Roman (too academic) |
| Business / Career | Cambria 11pt | Georgia 11pt | Comic Sans, informal fonts |
| Children (chapter books) | Georgia 13pt | Century Schoolbook 13pt | Complex serifs |
| Memoir | Garamond 11.5pt | Lora 11pt | Courier |
| Poetry | Cormorant Garamond | Garamond, Palatino | Bold, heavy fonts |

The standard guidance is 11–12pt for body text. That is correct but incomplete. Font size is only meaningful relative to the specific font’s x-height — the height of the lowercase letters. Garamond at 11pt reads visually larger than Times New Roman at 11pt because Garamond has a higher x-height. Merriweather at 10pt reads as large as Times New Roman at 11.5pt.
| Font | Recommended Size | Approx Pages (300 words/page) | Notes |
|---|---|---|---|
| EB Garamond | 11–12pt | ~260–290 | High x-height; reads larger than size suggests |
| Palatino Linotype | 10.5–11.5pt | ~265–295 | Efficient with space; very readable |
| Times New Roman | 11.5–12pt | ~285–305 | Go larger than instinct — small TNR looks cramped |
| Georgia | 10.5–11pt | ~255–280 | Larger x-height; do not go above 11pt for fiction |
| Lora | 11–12pt | ~270–295 | Warm and open; generous sizing works well |
| Merriweather | 10–11pt | ~280–305 | Heavy weight; smaller size is fine |
| Libre Baskerville | 10.5–11pt | ~265–285 | Slightly heavier than Baskerville; do not go too large |
Screen displays are misleading for font size decisions. What looks comfortable on screen at 11pt can feel tiny when held as a physical book. Always order a proof copy and read at least two full pages before finalising your font size. A change from 11pt to 11.5pt adds roughly 10–15 pages to a 300-page book — enough to shift your spine width — so factor this in.
This is the single most common technical error in KDP uploads that involves fonts. All fonts in your manuscript PDF must be embedded. If they are not, KDP either rejects your file or substitutes a different font — sometimes a completely wrong one that changes how your entire book looks and feels.
If you use a Google Font in Word, you need to download and install the font on your computer first — not just use it via Google Fonts in a browser. Download the font file from fonts.google.com, install it on your operating system, then set it in Word. This ensures Word can embed it correctly when exporting your PDF.

These fonts appear in a significant percentage of self-published books and are a reliable signal that a book was formatted by someone using default settings rather than making intentional typography choices.
| Font | Why to Avoid | Better Alternative |
|---|---|---|
| Calibri | Default Word font — screams “unformatted document” | EB Garamond or Palatino |
| Arial | Sans-serif — poor readability for long-form print | Georgia (if you prefer sans feel) |
| Times New Roman 12pt | Not wrong, but visually dated at 12pt | EB Garamond or Palatino |
| Comic Sans | Completely inappropriate for any adult book | Any serif on this page |
| Courier | Typewriter aesthetic — correct only for screenplays | EB Garamond or Palatino |
| Impact | Display font — unreadable at body text sizes | Not suitable for books |
| Decorative / Script fonts | Exhausting at body text sizes for 300+ pages | Use only for chapter headers |
Times New Roman is a legitimately good book typeface. It was designed specifically for newspaper body text and is extremely legible. The problem is that it is the default font for academic papers, legal documents, and Word templates — which means it carries associations that work against a reading experience. If you use Times New Roman, go up to 11.5pt and add slightly more leading (line spacing) to differentiate it from a document.
All Google Fonts are free to use commercially and can be downloaded, installed, and embedded in KDP PDFs. Here are the ones that actually work well in print — many Google Fonts are designed for screen use and do not print cleanly.
