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.

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.

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

Apple is reportedly preparing one of the biggest Siri redesigns in years with iOS 27, but even after multiple delays, the company may still label the upgraded assistant as a beta product. According to reports from Mark Gurman of Bloomberg, internal test versions of iOS 27 already refer to the revamped Siri as a beta experience and include an option allowing users to leave the Siri beta entirely.

The move would be unusually familiar for longtime Apple users. When Apple originally introduced Siri in 2011, the assistant itself launched under a beta label before Apple quietly removed the branding in 2013. Despite that, Siri has continued to face criticism for lagging behind competitors in reliability, conversational abilities, and overall intelligence.

Apple’s long-awaited Siri overhaul in iOS 27 could introduce a feature that most AI chatbots still treat as optional: automatic deletion of AI conversations. According to Mark Gurman's Bloomberg newsletter, Apple is preparing a redesigned Siri experience with a dedicated chatbot-style interface, but unlike rivals such as ChatGPT and Gemini, the company may make privacy controls a central part of the experience rather than a hidden setting.

The reported feature would allow users to automatically delete Siri conversations after 30 days, one year, or keep them permanently. The approach appears similar to the auto-delete system already available in Apple’s Messages app.

Amazon’s decision to cut support for older Kindles has pushed some longtime owners toward jailbreaking, a route many never expected to consider.

From May 20, 2026, Kindle devices released in 2012 or earlier will no longer be able to buy, borrow, or download new books directly from Amazon. Books already downloaded will still work, but the store experience is basically being switched off for these devices. Reports now suggest that some users are looking at jailbreaks as a way to keep older Kindles useful instead of replacing hardware that still works.
