I've had my Kindle for years and this issue used to drive me nuts. The font resetting to default usually happens when the device software updates or if there's a glitch in the book file itself. Amazon's updates sometimes overwrite custom settings.
Another common culprit is opening books from different sources—like sideloaded EPUBs converted via Send-to-Kindle. The formatting gets stripped, reverting to default fonts. Try redownloading the book directly from Amazon or converting files to AZW3/KFX format before sideloading.
Lastly, check if parental controls or reading profiles are enabled—they can lock font settings. A hard reset (holding power for 40 seconds) often fixes temporary software hiccups without losing data.

I’ve had my Kindle for years, and the font size issue is something I’ve wrestled with too. Sometimes, it feels like the settings just don’t stick, no matter how many times you adjust them. One thing I’ve noticed is that certain books, especially older ones or PDFs, don’t support dynamic font resizing as smoothly as newer EPUBs. If you’re dealing with a PDF, the font might be locked because the file is essentially an image.
Another culprit could be the Kindle’s software. I’ve had instances where a minor glitch prevents the font size from changing until I restart the device. Also, check if you’re accidentally pinching the screen, which can trigger zoom instead of font adjustment. If all else fails, a factory reset might be the nuclear option, but backup your books first!

I've noticed this issue too, and it's super frustrating when you're deep into a reading groove. The Kindle tends to default to whatever font settings the publisher has baked into the ebook file when you open a new novel. It's like the device forgets your preferences because each book acts as its own little universe with its own formatting rules. Amazon probably designed it this way to respect the publisher's layout choices, but it ends up feeling like a betrayal when you have to reset your preferred size every time.
There's also the possibility that it's a bug in the sync system. If you've adjusted font size on one device but open the book fresh on another, the settings might not carry over properly. I’ve found that sticking to one device or manually adjusting the default settings in the Aa menu helps, but it’s a band-aid fix. The real solution would be for Amazon to prioritize user preferences over publisher defaults, especially since most readers just want consistency across their library.

custom font sizes are a game-changer for readability. The trick is knowing that Kindle doesn’t save these settings globally—they stick to individual books. Here’s how I do it: open a book, tap the top to bring up the toolbar, then hit the 'Aa' icon. Adjust the font size to your liking, but don’t stop there. Scroll down to 'Theme' and pick one (like 'Compact' or 'Large'). This locks the size for that specific book.
For a semi-permanent fix, I use Calibre to modify EPUBs before sideloading. Convert the file to AZW3, then edit the CSS to embed your preferred font size. It’s a bit technical, but forums like MobileRead have step-by-step guides. Amazon’s quirks are frustrating, but this workaround gives me control over my reading experience. If you’re sideloading books often, it’s worth the effort.

I had the same issue with my Kindle last month, and it drove me nuts until I figured it out. The problem might not be with the settings themselves but with the book format. Some older or PDF-converted books don’t support font customization because they’re fixed-layout files.
Another possibility is a glitch in the update. Kindles sometimes need a hard reset after software changes. Hold the power button for 40 seconds until it restarts. If that doesn’t work, try deregistering and reregistering your device. It sounds extreme, but it often fixes stubborn settings issues. Also, double-check that you’re not in 'Publisher Fonts' mode—that locks the size. Go to 'Aa' > 'Font' and toggle it off.

I’ve had my Kindle for years, and I’ve run into this issue a few times. The font size adjustment might not work if your device is frozen or needs a restart. Try holding the power button for about 40 seconds until it reboots. Sometimes, the problem is caused by a corrupted book file. If it’s happening with a specific book, delete it and redownload it from your library.
Another possibility is that the book’s formatting doesn’t allow font changes. Some PDFs or older eBooks have fixed formatting. Convert the file to a Kindle-friendly format like AZW3 or MOBI using Calibre. Also, check if your Kindle’s software is up to date. Go to Settings > Device Options > Advanced Options > Update Your Kindle. If none of these work, a factory reset might be necessary, but back up your data first.

I've had this issue with my Kindle too, and it drove me nuts until I figured out a few things. The most common reason is that your device might be syncing with the cloud or another device where the font size is set differently. Amazon's Whispersync feature is handy for keeping your progress across devices, but it can mess with your settings if not configured properly. Another culprit could be the book itself—some publishers lock formatting options, so your changes don’t stick. Check if the 'Publisher Font' option is enabled under font settings; if it is, disable it. Lastly, a software glitch might be the cause. Restarting your Kindle or updating its firmware often resolves these quirks. If none of this works, contacting Amazon support is your best bet.

one thing that always bugged me was the font size resetting every time I switched books. After some digging, I found out that Kindle doesn’t save font size preferences per book by default. It keeps a global setting, so if you adjust the size for one book, it applies to all others too. It’s a bit frustrating because some books just feel better with larger or smaller text depending on their formatting. I wish Amazon would add this feature, but for now, I manually adjust it each time. Some third-party apps like Calibre might help tweak this, but it’s not a perfect fix.

I've had my Kindle for years and noticed the same thing—the font size won't go beyond a certain limit. After digging into it, I realized it’s a design choice by Amazon to ensure readability. If the text gets too large, it could mess up the formatting of the book, making paragraphs look awkward or even cutting off words. The max size is still pretty big, though, so it’s rare to need more. If you’re struggling, try adjusting the boldness or using the zoom feature for PDFs. Some third-party ebooks might have their own limits, but for most Kindle Store books, this is just how it works.
