What is the Best Page Size for an eBook?

Published On:

One thing that many authors often ponder is what’s the best page size for an eBook. In the digital world, where eBooks are becoming increasingly popular, choosing the right page size is crucial for a great reading experience.

Unlike traditional print books, eBooks offer more flexibility in how they are presented to readers. The page size you choose can impact how your book is viewed on various devices, from e-readers to tablets and smartphones.

In this article, we’ll explore the standard page sizes for eBooks and the factors that influence this choice. Whether you’re writing your first novel or creating a visually-rich cookbook, understanding page size will help ensure your eBook looks its best on any screen.

What is the Best Page Size for an eBook?

When it comes to eBooks, the concept of page size is quite flexible due to the variety of devices used for reading. However, there are some commonly used dimensions that work well with standard e-reader screens and apps.

A typical size for eBook pages is 6 x 9 inches, which works well for most novels and non-fiction books. This size is comfortable to read on standard e-readers like Amazon Kindle and fits nicely on most tablet screens.

Another common size is 5.5 x 8.5 inches, often used for smaller, more compact eBooks.

For eBook formats like EPUB and MOBI, the exact page size is less critical because these formats are reflowable. This means the text and images adjust to fit the screen size of the device, whether it’s a smartphone, tablet, or e-reader.

The key is to ensure that the eBook’s content is legible and aesthetically pleasing across different screen sizes, which these standard sizes generally accommodate.

In summary, while there’s no one-size-fits-all for eBook pages, sticking to standard dimensions like 6 x 9 or 5.5 x 8.5 inches is a safe bet for ensuring a good reading experience on most e-reading devices and apps.

Factors Influencing Page Size Choice

Factors Influencing Page Size Choice

Choosing the right page size for an eBook depends on several factors, primarily the eBook’s purpose and content.

Content Type

For text-heavy eBooks like novels or essays, standard sizes like 6 x 9 inches are ideal as they provide a comfortable reading experience similar to traditional books.

However, for image-heavy eBooks, such as graphic novels or cookbooks, a larger page size might be better to adequately showcase the images and maintain their quality.

Readability on Devices

The chosen page size should ensure readability across various devices. While e-readers and tablets adapt well to standard sizes, consider how your eBook will look on a smartphone.

Smaller screens may require a more thoughtful layout, especially for eBooks with complex formatting or numerous images.

User Experience

The overall user experience is key. The page size and layout should facilitate easy navigation and reading.

Reflowable formats like EPUB and MOBI offer flexibility, as the text adjusts to the screen size. However, if you opt for a fixed layout (common in PDFs), make sure the page size doesn’t compromise the readability on smaller screens.

In essence, the choice of page size should balance the need to present your content effectively while ensuring a comfortable and enjoyable reading experience on any device.

Page Size Recommendations for Different Genres

Additionally, choosing the right page size for an eBook can vary depending on its genre, as each type of book has different layout and content requirements:


For standard novels, which are mostly text, a 6 x 9 inches size works well.

It’s a common size for e-readers and provides enough space for comfortable reading without the text appearing too stretched or condensed.


Textbooks often contain a mix of text and images or graphs.

A slightly larger size like 7 x 10 inches can be more appropriate. This size gives more room for detailed content and complex layouts, making it easier for readers to absorb educational material.

Children’s Books

For children’s books, especially picture books, the page size should be large enough to showcase illustrations effectively.

Sizes around 8 x 10 inches or even up to 8.5 x 11 inches are suitable, as they provide ample space for both images and text in a child-friendly layout.

Illustrated Books

Similar to children’s books, illustrated books like graphic novels or art books need a larger format to display images clearly.

Opting for sizes like 8 x 10 inches or 8.5 x 11 inches can help maintain the quality and impact of the visual content.

Remember, while these sizes are recommendations, the final choice should align with ensuring the best reading experience while taking into consideration the reflowable nature of most eBook formats.

This flexibility allows the eBook to adapt to various screen sizes and orientations, making it accessible to a wider audience.

Formatting eBooks, especially considering page size and layout, requires specific tools and software that cater to the unique needs of digital publishing.
