AZW/KFX

Answer

Amazon Kindle uses the AZW and KFX formats derived from the MOBI standard, which Kindle devices and apps render natively.

Question 3

Why should authors avoid using tabs or multiple spaces to indent paragraphs in eBook files?

Accepted Answer

eBook reflowable text ignores tabs and spaces, causing unpredictable formatting across devices

Answer

Reflowable eBook formats resize text dynamically, so tab-based indents break formatting; CSS styles applied to paragraph tags are used instead.

A reflowable eBook dynamically adjusts its layout to match the reader's device screen size, orientation, and preferred font size.

Most retailers require eBook covers to be at least 2,500 pixels on the longest side at 300 DPI to look sharp on high-resolution tablet and phone screens.
