A large-print book is not simply a standard book with the font enlarged. A bigger type size changes line breaks, page count, margins, the weight of the finished book and sometimes the cover dimensions. The safest method is to design for the person who will read it, then test a printed sample before approving the full file.
This guide is useful if you are making a memoir, family recipe book, letters collection, church history or another personal book for an older relative or anyone who prefers larger type. “Large print” does not have one universal definition: the U.S. National Library Service for the Blind and Print Disabled notes 14 point in a particular U.S. postal definition, while RNIB’s reading guide describes large print more generally as 16–18 point. Treat those as context, not a guarantee that a particular reader will find a page comfortable.
Step 1: Ask the intended reader what is comfortable
Before changing the document, ask the reader—if possible—what works for them. Do they already read a particular printed book comfortably? Can they name the font size or show you a sample? Do they prefer a wider page, shorter lines, more space between paragraphs or a heavier-looking typeface? Is the book mostly text, or does it include recipes, family photographs, handwritten notes or tables?
These answers are more useful than assuming every senior reader has the same preference. Keep an existing large-print book nearby as a comparison, but remember that typefaces at the same point size can look different.
Step 2: Choose the physical page before laying out the text
Decide the finished book’s trim size before you set every page. A larger page can fit more characters per line, while a smaller page may feel easier to hold but create more pages. Neither choice is automatically best. Print a few pages at the proposed size and ask the reader to hold and read them in their usual setting.
Plan for the page count to grow when you enlarge type and spacing. Do not squeeze the margins or reduce the type at the end just to force the document back to its old length. The page count also affects the spine and full-wrap cover. Check the printer’s current size, margin and cover requirements together; Amazon KDP’s formatting guidance is one example of a provider explaining how trim size, margins and cover design relate, but the specifications of the service you use should control your final file.
Step 3: Set a consistent, readable type system in Word
- Save a copy of your manuscript so the regular edition stays unchanged.
- In Word, open Layout → Size and select the agreed finished page size before adjusting the text.
- Use Home → Select → Select All only to establish a first-pass body size. Then apply Word’s paragraph and heading styles consistently rather than formatting every page by hand.
- Increase line spacing enough that lines do not appear crowded. Add clear space between paragraphs where it helps the reader follow a recipe, letter or scene change; avoid making the whole page look like a collection of unrelated blocks.
- Keep chapter titles, subheads, page numbers and running heads visually distinct from body text. Use a restrained number of type styles so a larger page remains calm rather than busy.
- Check the inner margin near the binding. A reader should not have to force the book open or move it close to their face to follow text near the gutter.
Do not rely on a point-size number alone. A typeface with a larger apparent lowercase height can look more open than another face at the same setting. Print the sample at actual size; a zoomed screen preview is not a reliable substitute.
Step 4: Make photos, captions and special pages readable too
Large type cannot fix a crowded photograph page. Use images large enough for the chosen print size, preserve important contrast and keep captions close to the photographs they explain. Avoid placing small text over a busy image. For a family recipe book, check that ingredient quantities and method steps remain together; for a memoir, make sure a caption identifies who or what is pictured without becoming tiny legalistic type.
Inspect tables, footnotes, maps and handwritten material separately. If a detail cannot be enlarged clearly, consider a simpler redraw, a short explanatory caption or a larger dedicated page instead of shrinking the rest of the book around it.
Step 5: Export and print a representative sample
Export a print PDF using the printer’s stated requirements. Check that it uses the chosen page size, contains single pages in the expected order, and keeps fonts and images intact. Do not impose pages into printer spreads unless the print provider specifically asks for that file format.
Print a sample containing more than the first chapter. Include a dense page, a heading, a photograph and caption, a table or recipe if your book has one, and a page near the binding. Ask the reader to use it naturally, not just glance at it under ideal desk lighting.
A five-question sample test
- Can the reader find the start of a new chapter quickly?
- Can they read a full page without losing their place between lines?
- Do captions, page numbers and notes feel as usable as the main text?
- Does the book open comfortably and feel manageable to hold?
- What one change would make the next sample better: type appearance, spacing, page size, contrast or binding feel?
Write down the answer and revise only after the reader has had time to use the sample. If you change page size, typeface or spacing, export and check the revised PDF again: those changes can repaginate the whole book and affect the cover measurements.
Before you order the hardcover
Keep the reader-approved sample beside the final PDF. Confirm the title page, page sequence, page size, binding margin, image captions and final page count. Then make sure the cover was prepared for that same interior version.
If you are preparing a large-print family book and want help checking the files, send the manuscript or print PDF through YourBookBound’s file-check page. The standard $99 USD package includes one hardcover, manual file checking, layout and cover support, digital proof revisions and standard tracked global delivery. Include the reader’s preferred type appearance and physical page size with your files so the layout can be checked against the actual brief.
