Best e-readers: Kindle, Kobo and Pocketbook ebook readers rated

The e-reader market is dominated by Amazon's Kindle and Rakuten's Kobo. We've tested the latest generation of e-readers from both manufacturers, along with some alternative models from newer brands like Pocketbook.

We've found great e-book readers, but we've also uncovered screen issues including clouding effects and a noticeable hue to the background of some colour e-readers.

Whether you want to upgrade, switch to the competitor to take advantage of unique features or buy your first e-reader, we can help you select the right model for you.

How we test e-readers

Screen quality

We run a series of screen-quality tests in different light conditions to see if the screen is easy to read, and if each e-reader can continue to provide you with a clear picture.

We use every e-reader in bright sunlight. We then change the intensity of the light – just like when you're reading on the beach and the sun goes behind a cloud. From this, we can see whether the e-reader's screen automatically adapts to changing light conditions and or whether it remains comfortable to read.

E-readers are tested in living room conditions and in near darkness. This is to see how the built-in light copes, so you'll know if a device will work the way you want it to at night. We also use a luminance meter to measure the contrast value so we can provide an accurate assessment of the contrast ratio. The measurement is taken in three different light conditions: 

• Direct illumination with daylight source 
• Indirect illumination with fluorescent lamps in office surroundings 
• Indirect illumination with bulb lamps in office surroundings. 

Durability

The scratch test is performed with a stylus test pencil. We increase the force of the stylus point to a level where scratches or other problems could appear. Our tests reveal large differences in the resilience of each e-reader, even from the same manufacturer.

The drop test simulates the effect of an impact on the e-reader by dropping it in a tumbling drum six times. After the test we rate the amount of damage. In cases of serious damage, we repeat the test using a second sample. 

Ease of downloading ebooks

Getting ebooks onto your device is crucial to the e-reader experience. If the process isn't smooth and simple, and you're wasting valuable reading time wrestling with an awkward-to-use online store, you may wish you'd stuck with your trusty paperback instead.

We assess how easy it is to download books onto the device, as well as what file formats are supported, whether you're tied to one ebook store and if there's an option to borrow ebooks for free from an online library.

We regularly revisit the e-readers on sale to see if there are any more popular models that need testing, and when we find them, we do.

Kindle vs Kobo vs Pocketbook: which is best?

Kindle, Kobo and Pocketbook each offer a range of devices, including colour ebook readers with heaps of storage (useful for larger sized graphic novels, comics and audiobooks) and bigger models with more substantial screens. 

They also incorporate features that make reading ebooks easier on the eyes, such as adaptable brightness and colour temperature. But they also have some advantages over each other that may sway you one way or another.

Kindle

The Kindle Store has a library of several million ebooks, audiobooks and digital magazines (through Kindle Unlimited). Titles can typically be downloaded as a one-off purchase, but some formats, such as audiobooks and digital magazines, require particular subscriptions to access. Amazon has lots of subscription services on offer, which can make pinning down the right one for you confusing. For e-reader owners, the following are particularly useful:

• Kindle Unlimited This allows subscribers to download ebooks at a reduced price or even for free. It also grants you access to many digital magazines and audible versions of some ebooks.
• Prime Reading Packed into Amazon Prime membership, this gives you access to a range of ebooks, digital magazines and audiobooks. This service is not as expansive as Kindle Unlimited and offers fewer titles. Avid readers should opt for Unlimited instead.
• Audible This gives you access to the full catalogue of audiobooks from Amazon, including exclusive titles. You can download one new audiobook monthly, but you can also pay for further downloads. It's compatible with many Kindles, where you can listen via Bluetooth headphones and speakers, or through built-in speakers. 

We've found Kindle models to be universally easy to set up and use. They also have some features that are more intuitive than or even missing (such as text-to-speech) from Kobo e-readers.

However, Amazon has amended aspects of its Kindle service in the past and most recently restricted the ability to transfer purchased ebooks downloaded on your Kindle onto your computer. Previously, this feature was useful for transferring your ebooks onto other devices and served as a way to back up and preserve your ebook collection.

However, you'll still be able to download ebooks from the Kindle store over wi-fi, and you can also use the Send to Kindle page to send files in numerous formats, including already backed-up ebooks, to your Kindle.

Kobo 

The Kobo Store has an expansive library of ebooks, roughly equivalent in size to that of the Kindle Store. It's a straightforward digital store to browse and it also offers audiobooks in addition to traditional ebooks. These can be listened to via Bluetooth headphones or speakers connected to your Kobo e-reader. The subscriptions offered are more straightforward than with Amazon. These include: 

• Kobo Plus Read This includes full access to all Kobo ebooks.
• Kobo Plus Listen This offers full access to Kobo's range of audiobooks.
• Kobo Plus Read & Listen This offers full access to both the Kobo ebook and audiobook library. 

Outside of the Kobo store, you can import ebooks in a wide variety of formats – including EPUB – to your collection. You also have access to a number of Free Library sources to borrow ebooks – a feature not found on Kindle. 

Pocketbook

Pocketbook has recently made a major push into the UK e-reader market, which has long been dominated by Kindle and Kobo. Thanks to a partnership with Gardners Books in October 2025, Pocketbook says it can now deliver a vast 4.5m ebooks and 90,000 audiobooks to UK readers, rivalling its two big competitors' libraries. 

The Pocketbook.uk store is the main source to buy ebooks, and it's already integrated onto all Pocketbook devices. The Pocketbook reader app is also available. This allows you to read or listen to purchased ebooks or audiobooks on your phone or tablet.  

Easy side loading (the ability to transfer downloaded ebooks and other compatible file formats from your computer to your e-reader) is a much emphasised feature, and 25 formats are compatible with Pocketbook e-readers. These include PDF, EPUB, DjVu, FB2, FB2.zip, MOBI, DOCX, RTF, TXT, CHM, HTML (Basic), CBZ, CBR and CBT. It also supports audiobook formats such as MP3 and M4B. 

Pocketbook doesn't have a subscription service, instead favouring a pay-per-download model. It also allows you to borrow ebooks through services such as Libby.

Where to download free or cheap ebooks

If you're a prolific reader who wants to save money, there are several ways to get hold of free ebooks, particularly if you love the classics. Generally, books first published a century or longer ago have seen their copyright restrictions expire.

The Kindle Store has a selection of classic published books available for free (think Charles Dickens, Arthur Conan Doyle and Edgar Allan Poe novels). Beyond that, you may also find some self-published works available on the Kindle Store for free, although the quality of these will vary.

The Project Gutenberg website has a repository of 75,000 copyright-expired works from before 1924, so if you’re after a classic book you will likely find it there. They’re available in formats that work on Kindle, Kobo and Pocketbook e-readers.

You can transfer books to your Kindle in Word, PDF and Mobi formats, so if you've been given a freebie at an event or access to a university e-library, you can probably load the content onto your Kindle. Information on how to do this can be found at Amazon’s help pages. 

All of these formats, in addition to the open standard EPUB format, also work on Kobo e-readers. Information on how to do this can be found on Rakuten Kobo's help pages. Pocketbook e-readers are compatible with 25 formats. Information on transferring content over can found on Pocketbook's file management page.

In the UK, your local library may use a digital book borrowing service through companies such as Borrowbox or Libby (previously called Overdrive):

• Borrowbox This isn’t built into any e-reader, but you can download the Borrowbox app for a variety of devices, including Android and iOS phones and tablets.
• Libby This is built directly into Kobo and newer Pocketbook devices, but isn't compatible with Kindle. You can, however, also download the Libby app for iPhones, iPads, Android devices and Amazon Fire tablets to access it on these devices. Previously called Overdrive, its users were encouraged to make the switch to the Libby library reading app, made by the same company.

Whether you can access Borrowbox or Libby depends on what system your local library uses. You will need a valid library card to access the digital book loans on either system, so you’ll likely need to provide proof of address when you register with it. Check your local library branch to find out what’s available.

Is an ebook reader better than a tablet?

Although various ebook stores are available to download through Google Play and the Apple App Store – making access to their ebook libraries available on compatible tablets – a dedicated e-reader is designed specifically for reading ebooks, with unique features to make this easier and more comfortable. 

The e-ink display of e-readers is designed to be easier on the eye, so you should be able to comfortably read even under direct sunlight. Additionally, brightness and colour temperature can be adjusted to alter the image to better suit reading ebooks in different lighting conditions. 

E-readers are designed to be light and slim – even lighter than the average paperback – and offer weeks of battery life at a time. They also tend to be cheaper than most tablets, with superb basic models costing around £120. Plus, they're increasingly offering audiobook and text-to-speech compatibility. 

Tablets do have some advantages. They typically display colour images and content better and are more versatile devices for a range of other uses – e-readers aren't the best for browsing the web and can't play videos, for example. However, for the purpose of reading ebooks only, vastly poorer battery life and a less eye-friendly screen makes a dedicated e-reader still the best choice for enjoying your ebook library.  

Can you read magazines and newspapers on e-readers?

Kindle has the advantage in terms of the ability to read magazines and newspapers on your e-reader. Kindle allows users to easily access, download and view magazines and newspapers. If your magazine of choice provides PDF digital editions, it is possible to read them on Kobo and Pocketbook e-readers, but the experience is unlikely to be as smooth or easy.

While it's handy that Kindles allow you to easily access magazines, be sure to consider a colourised Kindle to take full advantage of images. Currently, only a few Kindle models have colour, and they still mostly lag behind traditional greyscale alternatives. However, if you're only interested in the words, it's a useful feature to have.

For many people, the preferred way to read digital magazines may still be on a tablet through apps such as Google Play, Readly and Apple Newsstand. These all offer access to a wide range of premium magazines.

Best ebook reader features to look for

• 4G connectivity All e-readers let you connect to the internet via wi-fi so you can download books and other content, but a few also let you connect over 4G. For a higher upfront cost, you get unlimited 4G connectivity for downloading ebooks and other items.
• Advanced screen lights All current-generation Kobo and Kindle ebook readers come with LED backlights. Some have lights that adapt to the time of day, so as it gets later, the light will turn a warmer yellow (rather than the harsher, bluer light used during the daytime). Some models also have automatic brightness adjustments based on lighting conditions. These functions can be manually adjusted, too.
• Faster processors Top-spec Kindle, Kobo and Pocketbook e-readers are typically faster than their cheaper siblings. This doesn't make a huge difference when reading ebooks (although you might notice page changes are slightly speedier), but it can be handy if you use your e-readers to browse the web or to navigate documents with images, such as PDFs.
• High-resolution screens Typically, the more you spend on an e-reader, the higher the resolution of the screen (meaning it looks sharper), measured in pixels per inch (ppi).
• Larger screens A bigger screen doesn't automatically mean a better e-reader, and you might prefer a more compact size if travelling or commuting. Currently, the ebook readers on test range between 6 inches and 10.3 inches, but most are typically either 6 inches or 7 inches.
• More storage Measured in gigabytes (GB), more storage inevitably adds to the price of an e-reader, and only people planning to download lots of image-heavy content, such as comics and graphic novels, or audiobooks, are likely to need a lot. If this is the kind of content you enjoy, one with more storage is recommended. 
• Waterproof An e-reader that can survive an unexpected rain shower or even a (brief) dip in the bath is handy. We test all e-readers with claimed waterproofing by plunging them in soapy water.

Are e-readers bad for your eyes?

Although all devices with screens will take a toll on your eyes, studies have shown that e-readers' e-ink (electric ink) displays, which closely mimic the appearance of ink on printed paper, can help reduce the potential problem of eye strain. 

If eye strain is a concern or you're an avid reader who likes to indulge in a good book over a long reading session, consider a model that comes with a screen light adjuster feature (whether automatic or manually applied). This helps adapt the screen to the time of day you're reading and can help reduce eye strain and let you keep reading for longer.

And to minimise long-term eye strain when reading from an e-reader: read in brighter environments where possible and take regular breaks during long reading sessions.
