I recently ran into this issue with my Kindle after an update, and it was frustrating because I rely on adjusting the font size for comfortable reading. The problem might be due to the update resetting some settings or a glitch in the firmware.
First, try restarting your Kindle by holding the power button for about 40 seconds until it reboots. If that doesn’t work, check if the book you’re reading has fixed formatting—some PDFs or older eBooks don’t allow font adjustments. Another thing to try is going into the settings and resetting the default font to see if that triggers the change. If none of these steps work, it might be worth contacting Kindle support since it could be a deeper software issue.

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 ran into this issue last week after updating my Kindle, and it was frustrating. The text size wouldn’t adjust no matter how many times I tapped the font settings. I realized the problem was tied to the book format. Some older PDFs or sideloaded files don’t support dynamic font changes. Converting the file to EPUB or AZW3 using Calibre fixed it for me. Another thing to check is whether the publisher locked the formatting—some DRM-protected books restrict customization. If it’s a Kindle Store purchase, try deleting and redownloading the book. Sometimes the update glitches the file.
Restarting the device also helps. Hold the power button for 40 seconds until it reboots. If none of this works, resetting font settings to default might clear the bug. Go to 'Display Settings' and tap 'Reset.'

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.

one of the things I love about it is how customizable it is. To change the font size quickly, you don't need to dive into menus. Just pinch the screen with two fingers and spread them apart to increase the font size or pinch them together to decrease it. It's super intuitive and works in most Kindle models. If you're using an older model that doesn't support gestures, you can still adjust the font size by tapping the top of the screen to bring up the toolbar, then selecting the 'Aa' icon to access the font settings. From there, you can slide the size up or down instantly. It's a small feature, but it makes reading so much more comfortable, especially when you're switching between different lighting conditions or just want a quick change without interrupting your flow.

I've had my Kindle for years, and adjusting the font size is something I do frequently. To reset it to default, you just need to tap the top of the screen to bring up the toolbar, then tap the 'Aa' icon for font settings. Inside that menu, there's an option for font size. You can slide it back to the middle position, which is usually the default. If you want to make sure everything else is reset too, like font type and boldness, just hit the 'Reset' button at the bottom. It's super straightforward and takes seconds. I do this whenever I lend my Kindle to someone else so they get the standard reading experience.

I ran into this issue last week after updating my Kindle, and it was super frustrating. The font just wouldn’t switch no matter what I tried. Turns out, the update sometimes resets custom settings or glitches during installation. I fixed it by restarting my Kindle—holding the power button for 40 seconds until it rebooted. After that, the font options worked again. If that doesn’t help, check if the book format supports font changes. Some older PDFs or sideloaded files might not have the feature. Also, make sure your Kindle’s software is fully up to date. Sometimes a follow-up patch fixes这些小bugs.
