We often get asked what an eBook filesize should be. It varies from retailer to retailer, but if you want to use one source ePUB file to all the retailers you need to keep it under 20MB. We’ve created a chart for you below.
| Retailer | Max Filesize |
|---|---|
| Amazon | 50 MB |
| Barnes & Noble | 20 MB |
| iBookStore | 2 GB |
| *Kobo | 200 MB |
*Note: As per Ben Dugas of Kobo they don’t automatically fail files that are larger than 200 MB but they are more likely to have performance issues or not load.
Lover of books. CEO & founder of Bibliocrunch. Love storytelling in all its forms. Formerly TIME. I'm a new media entrepreneur who has worked in the media industry for 11 years. My mission is simple – to innovate the publishing industry with technology. My company has been featured in BBC World News, Money Magazine, Bloomberg, Consumer Reports, Forbes, WSJ, MediaBistro, PBS, Columbia Journalism Review, The Next Web, Publishers Weekly, and a bunch of other places. Bibliocrunch was also selected as The Next Big Thing in media by the Paley Center. I also used to run a popular South Asian culture blog called Divanee. Before I ran my own company and became a mom, I used to be on the board for several literacy organizations, and wrote a LOT more. Hopefully, when things are calmer I can go back to that! :)
