Practical size limit on epubs

bobcdy · 11-12-2010, 03:11 PM

I'm working on an epub of a technical book with numerous figures, plates, and tables. All require images rather than text for best results because html tables have so many limitations in epubs. It looks like the epub will be perhaps 40 mb in size. I wonder if such a large file will be too slow to open and work with on a standard ereader?

Does anyone know about the practical size limits on epubs for ereaders?

Only one "flow" at a time is opened, so overall size really shouldn't be an issue.

This sounds like a job for SVG. Using it would also cut down the size.

I recommend Inkscape.

Harry, Valloric,
Thanks for the fast answers. I've been using png, butI'll look into svg (I have Corel Designer that does svg). If there is a significant size difference I might go to svg for the tables.

The size difference should be huge. SVG is a text-based format, and with epub's DEFLATE compression will compress very nicely.
