How Do You Publish a Large-Print Edition of a Book?

A standard paperback may look perfectly readable to its designer and still be difficult or impossible for someone with low vision to use comfortably.

Creating a large-print edition seems like an obvious solution. Increase 11-point text to 18 points, export the file again, and publish it.

In practice, that shortcut usually creates another problem.

The larger letters push sentences onto new lines. Paragraphs become much taller. Chapters begin in awkward places. Tables stop fitting. The page count can increase dramatically, changing the spine width, printing cost, cover dimensions, and retail price.

Professional large print book publishing requires the book to be redesigned as a separate edition.

The National Library Service for the Blind and Print Disabled notes that large-print materials are most commonly produced in 16- to 18-point type. The American Printing House for the Blind takes a more specific approach in its research-based guidance, recommending 18-point body text, 20-point subheads, and 22-point headings for large-print materials.

Font size is important, but it is only the beginning.

Treat Large Print as a New Edition

A large-print edition is not simply the standard paperback with bigger letters.

Changes may affect:

• Typography
• Paragraph treatment
• Line spacing
• Line length
• Margins
• Trim size
• Page count
• Tables and illustrations
• Index
• Cover dimensions
• ISBN
• Metadata
• Printing cost
• Retail price

These differences matter commercially as well as visually.

Bowker, the U.S. ISBN agency, states that each edition and format of a book requires its own ISBN. Its guidance also explains that redesigned editions are considered distinct products. A separately marketed large-print edition should therefore have its own ISBN rather than reusing the identifier from the standard paperback.

That separate identifier helps bookstores, libraries, distributors, and readers distinguish the large-print product from other editions.

Start With 18-Point Body Text as a Practical Baseline

There is no single print size that works for every reader with low vision.

The Library of Congress notes that 16- to 18-point type is common in large-print publishing. APH’s research-based guidelines recommend 18-point body text and larger sizes for headings.

For a general large-print edition, a practical starting structure is:

These are starting points rather than a guarantee that every reader will find the book accessible.

A publication designed for a particular group or individual may need larger text.

Typeface Choice Can Matter as Much as Point Size

Two fonts set at 18 points can look surprisingly different.

Letter shape, x-height, spacing, and stroke weight all affect readability.

APH recommends sans-serif fonts for readers with low vision and lists options including Verdana, Tahoma, Helvetica, Antique Olive, and its own APHont typeface.

When choosing a font, look for:

• Open letterforms
• Clear punctuation
• Strong distinction between similar characters
• Moderate weight
• Generous internal spacing
• Familiar shapes

Pay particular attention to:

• I, l, and 1
• O and 0
• c and e
• rn and m

Avoid making body text extremely thin, condensed, ornate, or decorative.

The goal is not to make the large-print edition visually unusual. It is to reduce unnecessary effort while reading.

Paragraphs Need More Room to Breathe

Increasing font size while keeping the original spacing can make the page feel crowded.

APH recommends approximately 1.25 line spacing for large-print documents. Its guidance also favors block-style paragraphs without first-line indentation, with additional space separating one paragraph from the next.

This does not mean every trade book has to reproduce an educational document exactly. It does show why large-print layout needs to be reconsidered instead of mechanically enlarged.

For a narrative book, test:

• 1.2 to 1.3 line spacing
• Clear separation between paragraphs
• Left alignment
• Minimal decorative formatting
• Comfortable space above headings

A page that contains larger text but almost no white space can remain tiring to read.

Keep Lines Short Enough to Track

One hidden problem with large print appears when publishers increase the trim size too aggressively.

A larger page can reduce page count, but it can also create extremely long lines.

APH recommends lines of approximately 39 to 43 characters for its large-print materials because shorter lines can make it easier for readers with low vision to move from the end of one line to the beginning of the next. It also discourages multi-column layouts for similar reasons.

Trade books may use somewhat different line lengths, but the principle remains useful:

Do not enlarge the page simply to force more words onto each line.

Print several sample pages and read them at actual size.

A layout that looks efficient on a computer monitor may be uncomfortable in the physical book.

Margins Need to Protect Both Text and Comfort

Large text placed too close to the gutter becomes difficult to read because part of the line curves toward the binding.

Allow enough inner margin for the book to open comfortably.

Printer specifications also establish minimum safe areas. IngramSpark, for example, currently recommends margins of at least 0.5 inches from the final trim size for non-bleeding text and artwork and warns publishers to keep important content away from trim edges because of normal manufacturing variation.

For large print, the design may benefit from even more generous space depending on:

• Binding
• Page count
• Trim size
• Paper
• Reader needs

A 500-page perfect-bound book may need a more generous gutter than a 120-page paperback.

Always confirm the requirements of the printer you will actually use.

Contrast Should Be Strong and Predictable

Black text on a light background remains one of the safest choices for sustained reading.

APH identifies black on white as offering strong contrast, while also noting that some readers experience glare from bright white paper and may prefer ivory, eggshell, light beige, or similar light backgrounds. It discourages gray text and gray paper for low-vision materials.

Avoid:

• Light gray body text
• Text over photographs
• Patterned backgrounds
• Low-contrast decorative pages
• Information communicated only through subtle color differences

Large print does not help much when the words are difficult to distinguish from the page behind them.

Tables and Graphics Often Need to Be Rebuilt

A table designed for an 11-point book may no longer fit after every label becomes 18 points.

Do not solve the problem by shrinking the table back to 8 or 9 points.

Instead, consider:

• Splitting one table into two
• Turning columns into shorter lists
• Moving explanatory material into prose
• Enlarging charts
• Simplifying labels
• Dividing complex diagrams
• Giving important graphics a full page

APH recommends enlarging graphics when necessary while preserving clarity and resolution.

The large-print edition should give readers access to the same meaningful information as the standard edition.

Simply Enlarging the Original PDF Creates Poor Results

A finished PDF already contains fixed:

• Page dimensions
• Line breaks
• Image locations
• Headers
• Footers
• Page numbers
• Margins

Scaling that PDF enlarges the page as an image-like unit. It does not intelligently redesign the content.

You may end up with:

• Cropped margins
• Oversized pages
• Long lines
• Blurry graphics
• Incorrect page breaks
• Tiny captions that remain unchanged
• Poorly positioned page numbers

Return to the editable manuscript or layout file.

Build the large-print edition as its own typesetting project.

The original book editing service style sheet should remain available so spelling, capitalization, terminology, character names, and editorial decisions stay consistent while the layout changes.

Choose the Trim Size After Testing Real Pages

Larger type generally increases page count.

A book that occupies 280 pages in standard print might grow substantially when set at 18 points.

A somewhat larger trim size can control that increase.

IngramSpark currently offers paperback trim dimensions ranging from 4 × 6 inches up to 8.5 × 11 inches for white-paper options, with somewhat narrower limits for cream and groundwood paper.

That does not mean an 8.5 × 11 format is automatically the best solution.

Consider:

• Reader comfort
• Book weight
• Portability
• Line length
• Shelf compatibility
• Genre
• Page count
• Printing cost

A 6 × 9, 7 × 10, or similar larger format may work well for some projects, but the correct size depends on the content and printer.

Test at least two layouts before making the final decision.

Expect Printing Costs to Change

Large print affects production economics primarily through page count and format.

IngramSpark states that print cost varies according to specifications including page count, binding, interior color, and format. Its current pricing examples show that an otherwise similar larger-format book can cost more per copy than a smaller one.

Suppose the standard paperback is:

• 6 × 9 inches
• 280 pages
• Black and white

The large-print edition might become:

• 7 × 10 inches
• 420 pages
• Black and white

The exact print cost should be calculated using the printer’s current calculator after the final page count is known.

Do not simply copy the standard edition’s retail price.

The final price must take into account:

• Unit printing cost
• Retail margin
• Distribution
• Wholesale discount
• Returns exposure
• Author compensation

Large-print accessibility should be taken seriously, but the edition also needs a financially sustainable production plan.

Give the Large-Print Edition Its Own ISBN and Metadata

Bowker states that each format or distinct edition should use its own ISBN so buyers receive the version they expect. ISBN data also supports discovery through Books In Print and other industry systems used by booksellers and libraries.

The metadata should clearly identify:

• Title
• Subtitle
• Author
• Large-print format
• ISBN
• Trim size
• Page count
• Publication date
• Price
• Publisher
• Language
• Subject
• Distribution information

Where your metadata system allows it, explicitly identify the product as a Large Print Edition.

Do not make customers determine the difference by comparing page counts.

Label the Cover Clearly

Readers should recognize the edition before ordering.

Place wording such as:

Large Print Edition

in a visible position on the front cover.

The cover still needs to retain the branding of the original book so readers understand that both editions contain the same work.

The larger page count will usually change the spine width, so the standard cover wrap cannot simply be reused.

Generate a fresh cover template using the final:

• Trim size
• Page count
• Paper selection
• Binding

A new ISBN also means a new barcode.

Check Rights Before Reproducing Third-Party Material

The standard edition may contain:

• Photographs
• Illustrations
• Lyrics
• Poetry
• Maps
• Charts
• Long quotations

Review the underlying book copyright permissions before automatically reproducing them.

A license may restrict:

• Format
• Territory
• Language
• Print quantity
• Edition
• Duration

If permission covered only the original paperback, the large-print edition may require an amendment.

The same issue should be identified earlier when a nonfiction book proposal depends heavily on licensed images or archival materials.

Editorial Work Should Be Finished Before Reformatting

Large-print production should not begin while the manuscript is still undergoing major structural revision.

A manuscript assessment belongs earlier, when chapters, pacing, argument, and organization may still change.

A sensitivity reader for books should also complete any significant representation review before final production.

Likewise, fact checking a nonfiction book should be substantially finished before pagination becomes important.

Reformatting a manuscript that later loses 8,000 words wastes production time and may change:

• Page count
• Cover spine
• Index
• Printing cost
• Retail price

Stabilize the content first.

The Index Must Match the Large-Print Pages

Authors learning how to index a book need to remember that print indexes depend on page locators.

A standard paperback might discuss a topic on page 184.

The same passage could appear on page 276 in the large-print edition.

The old index cannot simply be copied.

Create or regenerate the index after the large-print pagination is stable, then proof every locator against the new edition.

Order a Physical Proof Before Publishing

Do not approve the edition from an on-screen PDF alone.

A physical proof reveals things a monitor cannot.

Check:

• Actual font appearance
• Paper glare
• Text density
• Inner margin
• Book weight
• Page-turning
• Binding
• Image quality
• Table readability
• Page-number visibility
• Cover labeling
• Spine alignment

Ask readers who use large print to test the proof whenever possible.

Their experience may reveal that a technically correct design is still uncomfortable.

Recommended Large-Print Specifications

A useful starting specification for a text-heavy book is:

Body type: 18 pt
Subheads: 20 pt or larger
Main headings: 22 pt or larger
Typeface: Clear sans serif
Alignment: Left aligned
Line spacing: Approximately 1.25
Paragraphs: Clearly separated, with minimal reliance on indentation
Line length: Keep comparatively short and test readability
Columns: Avoid for primary reading text
Contrast: Dark text on a light, uncluttered background
Margins: At least printer minimums, with additional gutter space when needed
Trim size: Increase only enough to control page count without creating long lines
Edition identification: Clearly labeled “Large Print Edition”
ISBN: Separate from standard paperback or hardcover

These specifications draw on APH and Library of Congress guidance but should be adapted to the book and its intended readers.

Large-Print Production Checklist

Before publication, confirm that:

• The manuscript is editorially stable.
• Required permissions cover the edition.
• Body text is large enough for the intended readership.
• The typeface has clear letterforms.
• Line spacing supports comfortable tracking.
• Paragraphs are visually distinct.
• Lines are not excessively long.
• Text is not placed over distracting backgrounds.
• Contrast is strong.
• Tables and graphics have been redesigned where necessary.
• Margins meet printer requirements.
• The trim size remains comfortable to handle.
• The final page count has been confirmed.
• A new ISBN has been assigned.
• Metadata identifies the large-print format.
• The cover clearly says “Large Print Edition.”
• The new spine width and barcode are correct.
• The index matches the new pagination.
• Printing costs have been recalculated.
• A physical proof has been reviewed.

Large print succeeds when the edition feels designed for its readers rather than enlarged for them.

Frequently Asked Questions

What Font Size Should a Large-Print Book Use?

The Library of Congress notes that large-print books commonly use 16- to 18-point type. APH’s research-based guidance recommends 18-point body text for materials specifically designed as large print.

Does a Large-Print Edition Need a Separate ISBN?

Yes. A separately published large-print edition is a distinct product and should have its own ISBN so retailers, libraries, and customers can identify the correct version.

Can Authors Enlarge Their Existing Print PDF?

It is better to return to the editable layout file. Simply scaling a PDF does not properly adjust line breaks, margins, tables, graphics, navigation, or page design.

Should Large-Print Books Use a Bigger Trim Size?

Often, but not always. A moderately larger trim can reduce an excessive page-count increase, but the page should not become so wide that readers have difficulty tracking long lines.

Why Does a Large-Print Edition Cost More to Print?

Larger text often increases page count, which can increase manufacturing cost. Trim size, binding, paper, and interior color can also affect the per-copy cost.

Can Amazon A+ Content Be Used to Identify a Large-Print Edition?

Amazon A+ Content for books can help explain available formats to readers, subject to Amazon’s current content rules. The actual product listing, ISBN, metadata, and cover should still identify the large-print edition clearly so customers know which version they are purchasing.
