Book Sizes

Book sizes influence layout, readability, printing cost, and overall design structure. Different formats are used depending on genre, target audience, and publishing standards.
Choosing the correct book size ensures margins align properly, text flows consistently, and cover designs scale accurately for both paperback and hardcover formats.

Recommended vs supported sizes
Mass market paperbacks are designed at 3300 × 5100 pixels and are typically compact and portable.
Best practices for visibility
Use efficient margins and readable font sizes, as this format often includes dense text.
Quality and export considerations
Design at the final trim size and avoid resizing after layout completion to prevent formatting shifts.

Recommended vs supported sizes
Trade paperbacks use 3600 × 5400 pixels and are slightly larger than mass market formats.
Best practices for visibility
This format offers more space for comfortable reading and flexible layouts. Maintain balanced margins and consistent line spacing.
Quality and export considerations
Export at high resolution to preserve clarity in long-form text.

Recommended vs supported sizes
Hardcover books are commonly designed at 3900 × 5850 pixels and may include additional space for binding and cover wrap.
Best practices for visibility
Account for spine width and bleed areas when designing covers. Interior margins should allow for binding.
Quality and export considerations
Use precise measurements and export at full resolution for professional printing.

Recommended vs supported sizes
Square books use 3600 × 3600 pixels and are often used for art books or photo collections.
Best practices for visibility
Center layouts carefully and maintain symmetry. Square formats emphasize visual balance.
Quality and export considerations
High-resolution imagery is essential, especially for photo-heavy books.

Recommended vs supported sizes
Children’s books commonly use 3000 × 3000 pixels, often in square or nearly square formats.
Best practices for visibility
Use large typography and bold imagery to support readability and engagement.
Quality and export considerations
Avoid compressing illustrations, as color clarity and sharp edges are important for printed artwork.

• Design at the final trim size
• Account for margins, bleed, and spine width
• Use readable font sizes appropriate to format
• Export separate interior and cover files
