Buyer’s Guide

When choosing a new e-reader, here are the primary features to consider.


Unfortunately, your brand of e-reader sometimes determines the book marketplace that is available to you.

While most modern e-books are published in a wide range of formats, available on many devices, the brand of the device still determines the marketplace. For example, if you want the ease and convenience of Kindle Books and Amazon’s cloud storage, it’s best to use a Kindle brand e-reader.

If you prefer the Android marketplace, it is easier to access with an Android reader. If you want to borrow e-books from your local library, check which book formats are available to you and make sure your brand of reader uses OverDrive or compatible book files.


Some people strongly prefer e-readers with page buttons instead of e-readers with touchscreens. This can be a matter of preference and convenience, and which hand you prefer to hold and control your e-reader with. Some people also find touchscreen interfaces more challenging to navigate and control, with accidental interactions.

Screen Size

While you can easily change the font size on an e-reader for comfortable reading at different magnifications, screen size is still an essential factor. Most people prefer an e-reader about 6 inches or approximately the size of a paperback book page.

However, if you want additional space to take notes and interact with the text, you may want a larger e-reader, approximately the size of a notebook page. 


Connectivity is an important factor in an e-reader. You want to be able to access and read your book anywhere, even offline. And yet, you also need to be able to easily add books to the device and update your library.

Almost all e-readers have a charging cable that can also connect the device to a computer and manually add or remove files. However, Wi-Fi connectivity makes this process faster and easier and allows you to access books more quickly in cloud storage.

If you enjoy audiobooks, look for an e-reader that either has Bluetooth to pair with headphones or speakers or has a jack to connect to audio playback devices.

Size and Weight

Screen size is one of the primary factors that determine the overall size of your e-reader. While a large e-reader may be more comfortable for reading, it can also be more difficult to carry with you on the go.

E-readers with more ports, more memory, and built-in speakers may also be heavier than e-readers with less connectivity and media options. Most people prefer a lightweight e-reader that is easier to carry in a bag or pocket, but balancing features and capabilities with convenience and portability is essential.

Battery Life

E-ink technologies use little power, so most e-readers can last for days or weeks on a single charge. However, using an e-reader with more light and lighting options, downloading and controlling files by Wi-Fi, and reading for very long periods, will all drain the batteries more quickly.

Manufacturers typically estimate battery life based on no-light, offline use for ½ hour a day, so they estimate 6-10 weeks between charges. People who use bright light options or use their e-reader more extensively will need to charge it more often.


For most casual readers, an 8GB e-reader will hold thousands of books, and they will never need more memory. However, some types of e-books (like graphic novels, textbooks, or children’s books) contain many images and pictures, which require far more storage memory than text.

In addition, many textbook publishers create e-book versions of the book without being mindful of ways to reduce file size, which means that some textbooks can require 1GB or more memory per book.

If you read memory-intensive e-books, look for an e-reader with more built-in memory or with an SD card slot that allows you to expand storage over time.  


What Does an e-Reader Do?

An e-reader is a specialized device that displays text and images using “e-ink” instead of the LCD screens on monitors, tablets, and phones. There are two critical differences between an e-reader and another type of digital device like a tablet or a phone:

  • E-ink. Electronic ink (also called electronic paper) works by suspending many tiny, flat plastic plates that are black on one side and white on the other inside the screen.

    An electronic signal rotates all these tiny plates to have either the black or white side up and arranges them on the screen to display text or images. This system mimics the appearance of ink on paper.

    It also uses very little energy since the plates are rotated only once per “page,” and it doesn’t require electricity for them to stay in that position for as long as necessary.
  • Light. A typical phone or tablet screen is backlit, projecting light upward from behind the display. The beams of light are focused on various color combinations that create the images on the screen. This type of display uses electricity the entire time the display is on because light needs to be projected the whole time and aims light into the person’s eyes looking at the screen.

    e-Readers do not have backlights, and some e-readers don’t have light at all. When an e-reader has light, the lights are projected downward, onto the “page,” instead of outward, into the eyes. E-reader lights function like tiny lamps or book lights you might use when reading a traditional book. This reduces glare and eye strain when using an e-reader and creates a more book-like visual experience.

For these reasons, e-readers have an incredibly long battery life compared to other digital devices and are easier on the eyes when reading over long periods.

Which e-Book Reader Supports the Most Formats?

Kobo e-readers support the broadest range of book formats and are compatible with most e-book marketplaces. However, they are not compatible with Amazon’s Kindle marketplace.

If you want to buy a wide range of e-books directly from publishers and other marketplaces, a Kobo is the best choice. However, if you want the convenience of Amazon and Kindle cloud storage, you need to choose a Kindle e-reader.

What’s the Difference Between a Tablet and an e-Reader?

Visually, tablets and e-readers can look very much alike. The difference between the devices is the display, the light, and the capabilities. Here are the key differences between a tablet and an e-reader:

Electronic Paper vs. LCD Screen

As mentioned above, tablets use backlight to project colors that create text and images onto a screen. e-Readers use tiny flat plates to create a physical pattern on the screen.

Backlight vs. Front Light

Many e-readers do not have light, and when light is used, it is projected downward onto the “page.” On the other hand, tablets have backlighting that projects light outward from the screen into the reader’s eyes.


E-readers are really only useful for displaying text and images. They can display a vast range of text and book file types and image file formats (usually in greyscale). They may also have note-taking or drawing functionality or audio playback capabilities.

However, a tablet can do many functions, including reading, drawing, writing, playing games, watching movies, etc. You can also install new and different apps on a tablet, allowing new capabilities and activities. An e-reader has much more limited functionality and far less flexibility (if any) to expand its capabilities.  

How do I Get Books on an E-Book Reader?

There are typically two ways to get books onto an e-reader:

Download Using Wi-Fi

Most e-readers are linked to the e-book marketplace(s) and your user account(s). You can either buy new content from the e-reader itself or purchase new books from your phone or computer, and then the books are downloaded onto the e-reader through Wi-Fi.

Add Them With a USB

If your e-reader is offline or you have your own books to add to the device, you can add them via USB. First, connect your e-reader to your computer or tablet using a USB cable. Then, use your computer to browse the files stored on the e-reader and add or change them manually. 

Does Kindle Paperwhite Have Blue Light?

No, the Kindle Paperwhite does not have blue light. The 17 LED lights of the Paperwhite are cool to warm white in color and are aimed downward at the device rather than upward into your eyes.

Best Overall e-Reader

Our top pick for the best e-reader for 2021 is the Kindle Paperwhite. We love the brighter lights with adjustable color temperature to make for better reading in more places and conditions.

We love that it’s waterproof, so we can finally read at the beach or in the bathtub with less worry and care. And we love that Amazon has finally upgraded the USB port so the Kindle Paperwhite can charge more quickly.

In addition, the Paperwhite has seamless integration with Audible and our favorite audiobooks, Amazon’s cloud storage, and a larger, crisp, beautiful display. The Paperwhite is a great all-around e-reader with a great set of features that make it a good choice for nearly everyone.
