Kobo Clara HD design waterproof

Clara HD: 6-inch screen, not waterproof

The Kobo Clara HD has a 6-inch HD screen. The size of this e-reader can be compared to a postcard. Thanks to its compact size and light weight of 166 grams, you can easily take the Clara HD with you in your bag. This model isn't waterproof. Because of this, you have to be careful when reading in the bath or on the beach. The e-reader is made of plastic and is fairly sturdy.

Kobo Libra H2O waterproof design

Kobo Libra H2O: 6.8-inch screen and waterproof

The 6.8-inch screen of the Kobo Libra H2O is slightly larger than that of the Clara HD. This sharp Full HD screen lets you read more comfortably than the HD screen of the Kobo Clara. The device is also water-resistant, so you can take the e-reader to the pool without worries. The Libra has an ergonomic handle on the side of the device. That way you can easily hold the e-reader comfortably for a longer period of time. The Libra also has a plastic exterior.

Kobo Forma waterproof large

Kobo Forma: 8-inch screen and waterproof

The Kobo Forma has a large 8-inch Full HD screen. Because of the large, bright screen and the handle with buttons, this e-reader is about the size of a notepad. The Forma is waterproof and made of a somewhat stronger material than the other 2 e-readers. That's useful if you take the e-reader outside a lot. The screen is also made of a more luxurious material, so it stays in good condition for longer.


Kobo Clara adjust brightness

Clara HD: Comfortlight PRO

The Kobo Clara HD has 8GB of storage capacity. You can easily store more than 8000 e-books on this. Thanks to 512MB of RAM, the Clara HD runs relatively smoothly. This means you don't have to wait too long before your page turns. This e-reader also features Comfortlight PRO. With this, you can adjust the brightness of the screen and the color temperature to your liking. This way, you can also read a book in the evening without straining your eyes.

Kobo Libra handle with buttons

Libra H2O: ergonomic handle with buttons

On the handle of the Kobo Libra are physical buttons with which you can easily browse through the menu and your books. It works a bit faster and more accurate than browsing via the touchscreen. Thanks to Comfortlight PRO, this model also gives you the option to adjust the brightness of the screen to your preference. The RAM and storage capacity are the same as those of the Kobo Clara, so you also store around 8000 e-books on your Libra H2O.

Kobo Forma large 8-inch screen

Forma: more space on the 8-inch screen

You don't have to turn pages as often on the large 8-inch screen of the Forma. The e-reader is also excellent for reading PDF files (magazines), manga, or graphic novels. You almost never have to zoom in, something that's often fairly slow and awkward on e-readers. Just like the Libra, the Forma has an ergonomic handle with physical buttons. You set the brightness of the lighting via Comfortlight PRO and you have storage space for 8000 e-books.
