What You Need

  • Any Amazon Kindle device

But when you’re reading on an e-reader, you may need to adjust the font and text size to better suit your own personal needs, as the default settings may not be for everyone. Thankfully, your Kindle reading experience can be tweaked to however you want, and it’s quite easy.

Whether you have the base model Kindle, a Kindle Paperwhite, the Kindle Colorsoft, or the Kindle Scribe, here’s how to do it.

How to adjust your book's font size on your Kindle

When it comes to reading, the typeface and size used can really make all the difference in terms of a comfortable experience. After all, you don’t want to have tiny font if you have to strain your eyes, and you don’t want a large font if you want as much text as possible on the screen at once to reduce page turns.

Step 1: Navigate to your Library on your Kindle device.

Step 2: Select a book you want to read.

Step 9: Tap anywhere outside of the settings box to exit.

How to adjust the book's theme and layout settings on your Kindle

In addition to adjusting the font and size, you can also adjust the theme or layout of your books. On a Kindle, a theme is like a preset setting for the font size and layout, but these can be tweaked to your own personalized needs too.

The Razr Fold now gets along better with iPhones thanks to AirDrop
Motorola's first foldable learns a new trick, and I guess I'm ready to daily drive it now
Electronics, Speaker, Electrical Device

I already had more reasons than expected to keep the Motorola Razr Fold around. While reviewing it, the company's first foldable genuinely surprised me with its level of polish. A practical outer display, great cameras, strong battery life, and a gorgeous folding screen. All of this made me want to switch to this device as my primary phone.

Now Motorola has added one more reason, and it's just sweetening the deal for me. The Motorola Razr Fold now supports AirDrop-style sharing through Android’s Quick Share, making it the first Motorola phone to get the feature. That means Razr Fold users can share files directly with Apple devices such as iPhones, iPads, and Macs without relying on cloud links, messaging apps, USB cables, or the usual cross-platform nonsense.
