New authors often ask which single format they should publish in, as though there is one correct answer that applies across all books. In practice, format is a set of trade-offs rather than a hierarchy, and the right combination depends heavily on what kind of book it is and who is expected to read it.
This guide walks through what each format actually offers, where they tend to suit different genres and goals, and the practical implications of offering more than one. For the technical side of preparing an EPUB once you have decided to offer an ebook, see [what is an EPUB?](/resources/book-design/what-is-an-epub)
Paperback
Paperback remains the default expectation for most fiction and much non-fiction, particularly through print-on-demand routes such as Amazon KDP and IngramSpark, where paperback editions are generally straightforward and comparatively inexpensive to produce per unit. Paperback is portable, familiar to readers, and usually priced lower than hardcover, which tends to support higher volume sales.
Hardcover
Hardcover editions typically cost more to produce and are priced higher at retail, which can suit readers who see a hardcover as a gift, a collectable, or simply their preferred reading format. Hardcover print-on-demand options are available through some platforms, though availability, binding options and specifications vary by platform and should be checked directly against current documentation before assuming a particular option exists.
Ebook
Ebooks have no print or shipping cost per copy, can be priced lower than print editions, and are read on phones, tablets and dedicated e-readers. For many genre fiction readers, ebook is the primary or even sole format they buy in, while other readers, particularly in some non-fiction and gift categories, may rarely or never buy an ebook version of a given book.
Advantages by format
Paperback offers affordability and physical presence at a manageable production cost. Hardcover offers perceived value, durability and gift appeal. Ebook offers instant access, portability across an entire library on one device, and typically the lowest cover price. None of these advantages makes one format objectively "better"; they answer different reader needs.
Trade-offs
Offering more formats generally means more production work: separate cover files sized for each format, potentially separate ISBNs, and separate pricing decisions across possibly different platforms. It can also mean a longer path to publication if all formats are prepared and launched simultaneously, which is one reason some authors choose to stagger releases instead.
Fiction
Fiction, especially genre fiction such as romance, thriller and fantasy, often sells strongly in both ebook and paperback, with hardcover sometimes reserved for later editions, special editions or particularly popular titles. Series fiction in particular tends to benefit from consistent paperback and ebook availability across every instalment.
Business and non-fiction
Business and professional non-fiction is frequently bought in paperback for reference use and in ebook for portability, with hardcover sometimes used as a premium or speaking-engagement edition. Readers in this category are often less price-sensitive than genre fiction readers, which can support a hardcover option even without high print volumes.
Children’s books
Children’s picture books are overwhelmingly a print category, generally in paperback or hardcover, because much of their value lies in the physical book-sharing experience between an adult and a child. Ebook editions exist for this category but occupy a smaller role than they do in adult fiction, and require particular attention to layout, discussed further in what is an EPUB?
Memoir
Memoir readers often buy both ebook and paperback, with paperback sometimes preferred for gifting to family or friends connected to the story. A hardcover edition can suit a memoir positioned as a keepsake or intended for wider media or speaking exposure.
Gift books
Books explicitly positioned as gifts, whether illustrated, humorous or commemorative, generally lean towards hardcover or a high-quality paperback, because the physical object is central to the purchase decision. An ebook-only edition would undermine the purpose of a book bought specifically to be given and displayed.
Series
Consistency across a series matters: readers who buy book one in paperback often expect to continue in the same format, and mismatched formats across a series can create friction, both for reader experience and for how neatly the books display together on a shelf.
Launching formats together
Launching ebook and paperback simultaneously is common and generally achievable within a single production timeline, since both rely on largely the same interior files, adapted for each format’s requirements. Adding hardcover at the same time is possible but adds further production and cost considerations.
Staggered releases
Some authors deliberately release an ebook and paperback first, then introduce a hardcover edition later, sometimes tied to a milestone such as strong early sales, a later print run, or a special edition. This is a legitimate strategy rather than a sign of an incomplete launch, and can reduce upfront cost and complexity.
ISBN implications
Each print format is generally treated as a separate publication and typically needs its own ISBN, while ebook ISBN requirements vary by platform. Authors planning multiple formats should factor this into their ISBN planning rather than assuming one number covers everything; see our companion guide on how many ISBNs a book needs for the fuller picture.
Pricing
Pricing across formats usually reflects production cost and reader expectations: ebooks are typically priced lowest, paperback in the middle, and hardcover highest. Pricing too far outside these norms for a given genre can affect how a book is perceived and how it performs against comparable titles.
Print costs
Print-on-demand cost varies by page count, trim size, ink (black and white versus colour) and binding, and directly affects the achievable royalty at a given retail price. Because print costs are set and periodically updated by each printing platform, check current calculators on Amazon KDP or IngramSpark before finalising pricing across formats.
Distribution
Print formats intended for bookshop and library ordering generally rely on distribution routes such as IngramSpark, while ebook distribution runs through separate retailer-specific or aggregator routes. The format decision therefore has knock-on effects for which distribution channels are relevant; see understand distribution for the broader picture.
Reader expectations
Ultimately, reader expectations within a genre or category are a strong guide to which formats are worth prioritising. Looking at comparable, successfully selling titles in the same category and noting which formats they offer is a practical way to sense-check a format decision before committing production budget to all of them at once.
Common mistakes
- Assuming hardcover is always the "premium" choice worth adding. Hardcover only adds value where readers in that category actually buy hardcover; in many genre fiction categories, it adds cost without matching demand.
- Launching every format at once without capacity to support them. Preparing paperback, hardcover and ebook simultaneously adds production complexity that can be better managed in stages.
- Ignoring genre norms. Publishing a genre fiction title in hardcover only, with no ebook, can cut off the audience most likely to buy it.
- Treating one ISBN as valid for every format. Each print format generally needs its own ISBN; assuming otherwise causes distribution and cataloguing problems later.
- Pricing formats inconsistently with reader expectations. Pricing an ebook close to the paperback price, without a clear reason, can depress ebook sales relative to genre norms.
Frequently asked questions
Do I have to choose only one format?
No. Many books are published in more than one format, most commonly ebook and paperback together, with hardcover added where the genre and audience support it.
Is hardcover always more prestigious than paperback?
No. Perceived value depends on genre and reader expectations; some categories rarely use hardcover, while others treat it as standard for a serious title.
Can I add a hardcover edition after launch?
Yes. A staggered release, adding hardcover later, is a common and legitimate strategy rather than a sign of an incomplete launch.
Does each format need its own ISBN?
Generally, yes, for print formats. Ebook ISBN requirements vary by platform, so check current guidance for the specific platform you are using.
Which format should I prioritise for a tight budget?
Looking at comparable, successful titles in your category and matching the formats they offer is a practical way to prioritise limited production budget.
