For most novels and general nonfiction books, 6 × 9 inches is the safest choice. Compact fiction often uses 5 × 8 or 5.5 × 8.5 inches. Workbooks usually need 7 × 10 inches, while manuals with large tables or writing areas suit 8.5 × 11 inches.
Standard book sizes give buyers a useful starting point, but no single format fits every project. The right size should suit the content, page count, reading experience and finished book weight.
| Book Type | Recommended Size | Metric Size | Best Use |
|---|---|---|---|
| Compact fiction or poetry | 5 × 8 in | 127 × 203 mm | Shorter books and portable editions |
| Fiction or memoir | 5.5 × 8.5 in | 140 × 216 mm | Compact text-led books |
| Novels and general nonfiction | 6 × 9 in | 152 × 229 mm | Most fiction, business books and biographies |
| Textbooks and workbooks | 7 × 10 in | 178 × 254 mm | Exercises, diagrams and note-taking |
| Illustrated or activity books | 8 × 10 in | 203 × 254 mm | Larger images and mixed page layouts |
| Manuals and training books | 8.5 × 11 in | 216 × 279 mm | Tables, instructions and writing space |
| Square picture books | 8 × 8 in | 203 × 203 mm | Illustration-led children’s books |
| Large square picture books | 8.5 × 8.5 in | 216 × 216 mm | Larger illustrations and double-page scenes |
These are finished page dimensions. For measuring rules, artwork setup and the difference between page size and cover size, see our trim size for book printing guide.
Choose 6 × 9 inches for most novels, biographies, business books and general nonfiction. It provides a comfortable text area without making the book feel oversized.
A 5 × 8 or 5.5 × 8.5-inch format creates a more compact book. It suits poetry, memoirs and shorter fiction, but the smaller page area usually increases the total page count.
For a long manuscript, 6 × 9 inches is normally more practical. It keeps the book from becoming unnecessarily thick while maintaining a familiar reading format.
Choose 7 × 10 inches when readers need space for exercises, diagrams or notes. It provides more working room than a novel-sized page while remaining easy to handle.
Use 8.5 × 11 inches for training manuals, educational workbooks and technical content with large tables or detailed instructions.
Do not force a complex workbook into a small format. Reducing the page size can make the text, answer areas and diagrams difficult to use.
Choose 8 × 8 or 8.5 × 8.5 inches when illustrations carry most of the story. Square pages work well for full-page artwork and scenes that continue across a spread.
Portrait formats suit vertical compositions and text-led pages. Landscape formats are better for panoramic scenes, maps and wide illustrations.
The artwork should guide the orientation. Changing the proportions after the illustrations are complete can create awkward cropping or unused space.
A smaller trim size places less text on each page. The same manuscript may therefore need more pages in a 5 × 8-inch edition than in a 6 × 9-inch edition.
More pages create a thicker book and can increase paper, binding and shipping costs. A larger format may reduce the page count, but it should not leave the layout looking empty.
The trim size, type size, margins and line spacing need to work together. Changing only the page dimensions rarely produces the best result.
Large pages are useful for tables, illustrations and writing space, but they are not automatically better for continuous reading. Long lines of text can make a novel tiring to read.
Small pages create the opposite problem when they contain several images, columns or technical diagrams. The layout becomes crowded and the text may need to be reduced too far.
The page should provide enough room for the content without creating excessive blank space.
Larger book dimensions require larger cartons and take up more storage and shipping space. The difference becomes more noticeable when the book has a high page count, heavy paper or individual packaging.
If the book must fit inside a slipcase, gift box or retail set, confirm the complete structure before fixing the page size.
They can use the same interior page size, but their final exterior dimensions will differ.
A hardcover case extends beyond the page block, making the finished hardcover slightly taller and wider than a paperback with the same trim size. Board thickness and cover construction also affect the final measurements.
When producing both editions, the same interior layout can be retained if the page size remains unchanged. The hardcover and paperback covers still require separate production files.
Use a standard size when the book follows a familiar publishing format and does not need unusual proportions. Standard book dimensions generally offer more efficient paper use, easier packing and a format readers already recognize.
They are also useful when future volumes or reprints need to remain consistent.
A custom size is justified when:
Existing artwork uses a specific proportion.
A new volume must match an established series.
The book must fit a slipcase or presentation box.
The format is part of the product concept.
A standard size would weaken or crop the page design.
Custom dimensions should be confirmed before the final layout is completed. Both standard and custom formats are available through our custom book printing service.
6 × 9 inches is the most common practical choice for novels and general nonfiction in the US market. It provides a comfortable text area and works across a wide range of page counts.
Not always. A smaller page uses less paper area, but it can increase the total number of pages. Printing cost must be calculated from the trim size, page count, paper, binding and quantity together.
Use 8 × 8 or 8.5 × 8.5 inches for a square picture book. Choose a portrait or landscape format when the illustration style clearly favors that orientation.
Start with 6 × 9 inches for text-led books, 7 × 10 inches for workbooks and 8 × 8 inches for square picture books. Move to a larger or custom format only when the content, illustrations or packaging structure genuinely requires it.
