In this guide, we’ll break down the factors that influence book size choices and offer insights into selecting a size that enhances your book’s design and meets reader expectations.

Common Book Sizes for Various Genres

When it comes to self-publishing, choosing a book size depends on the genre, purpose, and intended reader experience. Here are standard sizes tailored for different types of books.

Novels and Fiction

5″ x 8.5″ (13.97 cm x 21.59 cm)
6″ x 9″ (15.24 cm x 22.86 cm)

The 5.5″ x 8.5″ size is versatile and popular for genres like romance, mystery, science fiction, and general fiction. This size strikes a good balance between portability and readability, allowing for a comfortable reading experience.

The slightly larger 6″ x 9″ format is also common for novels, memoirs, and biographies. This size gives more space per page, making it ideal for larger font sizes and spacious layouts. It’s a standard choice in bookstores and provides a classic, professional look.

Some authors may opt for pocket-sized editions for portability or larger formats, like 7″ x 10″ または 8.5″ x 11″, to make a visual statement or accommodate design elements.

Children’s Picture Books

6″ x 6″ (15.24 cm x 15.24 cm)
8″ x 8″ (20.32 cm x 20.32 cm)

Children’s books often favor square formats for easy handling by little hands. Smaller sizes are ideal for board books, while larger sizes, like 10″ x 8″, work well for picture books aimed at young readers, allowing room for detailed illustrations.

For older children’s illustrated books, 8.5″ x 11″ is popular, offering more space for text and visuals. Landscape formats can also create an immersive experience by providing a wide canvas for expansive illustrations and scenes.

Coffee table books are often larger to showcase stunning images and layouts. These dimensions make them eye-catching display pieces while remaining easy to handle for readers. Larger sizes allow for striking visuals and a layout that draws readers in, perfect for books with photography, art, or unique designs.

Comic Books

6.625″ x 10.25″ (16.83 cm x 26.04 cm)
