No — do not use Times New Roman for a book interior. Times New Roman was designed in 1931 for The Times newspaper — its narrow letterforms are optimized for cramming text into narrow newspaper columns, not for comfortable reading in a 5.5×8.5 book. Using Times New Roman is the single fastest way to make a professionally written book look self-published. Every publishing professional — agents, editors, reviewers, bookstore buyers — recognizes it instantly.

Why Times New Roman doesn’t work for books

IssueExplanation
Too narrowCharacters are compressed to save newspaper column space — uncomfortable for book-length reading
x-Height is awkwardNeither small enough for elegance nor large enough for easy reading
Tight spacingLetter spacing designed for dense newspaper columns, not the generous space of a book page
Signals “default”Everyone knows it was Word’s default font for 20 years — it says “I didn’t think about typography”
No publishing house uses itZero traditionally published novels use Times New Roman for interior text

What to use instead

These 5 fonts will immediately make your book look professionally published:

FontWhyFree?
GaramondThe publishing industry standard — warm, elegant, space-efficientEB Garamond (free)
PalatinoWider and warmer — excellent readability for long booksSystem font (free)
BaskervilleRefined and crisp — great for thrillers and nonfictionLibre Baskerville (free)
CaslonOrganic, warm — perfect for literary and historical fictionLibre Caslon (free)
Minion ProModern classic — clean and professionalAdobe subscription

Any of these fonts, at 11pt with 1.35× line spacing, will make your book look like it came from a major publisher. The change takes 30 seconds and the impact is enormous.

The real cost of Times New Roman

Page count

Times New Roman at 12pt (the Word default) produces more pages than proper book fonts at 11pt:

Font & SizePages (80K words, 5.5×8.5)
Times New Roman 12pt~320
Garamond 11pt~280
Palatino 11pt~300
Baskerville 11pt~290

Switching from TNR 12pt to Garamond 11pt saves ~40 pages — that’s $0.48 less per copy on KDP, or $480 per 1,000 copies.

Reader experience

In a 2012 study by filmmaker Errol Morris (published in the New York Times), readers rated statements in Baskerville as more believable than the same statements in other fonts. Typography affects how readers perceive your writing — subconsciously but measurably.

”But my manuscript is in Times New Roman”

That’s fine. Manuscripts submitted to agents and editors are traditionally in Times New Roman 12pt, double-spaced — that’s a submission format, not a publishing format. They’re completely different:

Manuscript (submission)Book interior (publishing)
FontTimes New Roman 12ptGaramond/Palatino/Baskerville 11pt
SpacingDouble-spaced1.3–1.45× leading
Margins1” all sidesVaries by trim and page count
PurposeEasy for editors to read and mark upComfortable for readers to enjoy

When you move from manuscript to book, you change the font. Always.

Other fonts to avoid in books

FontWhy Not
CalibriWord’s current default — designed for screens, too light for print
ArialSans-serif, designed for screens — fatiguing for book-length reading
HelveticaSame issue — sans-serif body text doesn’t work in print books
Comic SansNever
CourierMonospace — designed for typewriters. Use only for stylistic elements (ship logs, code)
CambriaDesigned for screens, too heavy and square for book pages

How to switch fonts

  1. Choose a book font — Garamond if you’re not sure (it’s always right)
  2. Set body text to 11pt — not 12pt
  3. Set line spacing to 1.35× — not double-spaced
  4. Adjust margins for your trim size — not 1” all around
  5. Export as PDF with fonts embedded

Or use Cambric — import your manuscript and the typography is handled automatically.
