Why Won'T My Kindle Font Size Change Stay Saved?

As someone who's been using Kindle for years, I've encountered this issue multiple times, and it can be incredibly frustrating. The Kindle font size not staying saved usually happens due to a few common reasons. First, if your device isn't syncing properly with your Amazon account, settings like font size might reset. Make sure your Kindle is connected to Wi-Fi and try manually syncing it.

Another possible culprit is the book format itself. Some older or non-Amazon eBooks might not support persistent font settings. If you sideloaded the book, converting it to a Kindle-friendly format like MOBI or AZW3 using Calibre could help. Also, check if you have the 'Publisher Font' option enabled in the Aa menu, as this can override your custom settings.

Lastly, a software glitch might be causing the problem. Restarting your Kindle or even performing a hard reset (holding the power button for 40 seconds) often resolves these minor bugs. If none of these work, contacting Amazon support might be your best bet, as they can check for deeper issues with your device or account settings.

I've had this exact problem with my Kindle Paperwhite, and after some trial and error, I figured out what was going wrong. The font size wouldn't stay because I was reading a library book borrowed through Libby. Apparently, some borrowed books have restrictions that prevent permanent changes to display settings. When I bought the same book from Amazon, the font size stayed as I set it.

Another thing I noticed is that collections behave differently. If I change the font in one book, it doesn't automatically apply to others, even in the same collection. You have to set it individually for each book, which is annoying but makes sense if you think about it. Sometimes the issue disappears after a software update, so always keep your Kindle updated. Also, try disabling the 'Page Refresh' option in settings, as I've heard this can sometimes interfere with display preferences.

This drove me crazy until I discovered the trick. The Kindle saves font settings per book, not globally. So if you're jumping between different titles, you'll need to set the font size for each one individually. What's more confusing is that even within the same series, the settings don't carry over between books. I learned this the hard way with 'The Wheel of Time' series - had to adjust the font fifteen times!

Also, check if you're using the 'restore previous reading location' feature. For some reason, this sometimes resets font settings too. My solution was to turn off automatic page sync and manually manage my reading progress. Another workaround is to use the same font for all your books - once I stuck with Bookerly, I had fewer problems with settings changing unexpectedly.

The most common fix for this is simple - update your Kindle. I had this issue last month, and after installing the latest software version, my font settings stayed put. Sometimes it's just a bug that Amazon has already fixed. Also, try deleting and redownloading the problematic book. I found that corrupted ebook files can cause all sorts of display issues. If you use the cloud reader, check those settings too, as they can override your device preferences.
