Large Print Book Publishing ServicesProfessional Formatting, Wide Distribution, Correct Specifications
Large print books use 16pt or 18pt font size, wider leading, larger trim sizes (typically 8.5 x 11 inches) and higher-contrast design to serve readers with visual impairments, older readers and those with reading difficulties. They are a distinct format with specific production requirements and distinct distribution channels. Columbia Publication produces large print editions alongside standard editions, registering separate ISBNs and setting up distribution through library systems and specialist large print retailers.

Large print books use a minimum of 16pt font. The American Printing House for the Blind and most library systems define large print as 16pt or larger. Many large print editions use 18pt for body text. The increased font size is combined with wider line spacing (leading) and larger trim sizes to ensure readability.
The standard trim size for large print books is 8.5 x 11 inches (letter size). This larger page area accommodates the larger font while maintaining readable line lengths. Some large print editions use 7 x 10 inches for a slightly more compact format. The trim size is chosen to balance readability with physical usability.
Library distribution for large print books works through IngramSpark, which connects to the wholesale distributor network used by public library systems. Libraries actively purchase large print editions for their visually impaired patron collections. Specialised large print library distributors and programmes also exist for targeted library distribution.
Yes. Each format and edition of a book requires its own ISBN. The large print edition is a distinct format with its own production specifications and its own place in library catalogues and retail systems. We register a separate ISBN for each edition as part of the publishing process.
A large print edition typically adds $300 to $600 to the production cost of a standard edition because it requires separate interior formatting to large print specifications. If published simultaneously with the standard edition, the editorial and cover work is shared and only the formatting is additional.
