Kobo Clara BW: Specs, Price, Pros & Cons
The Clara BW is the Clara Colour without the color filter. Both share a six-inch screen, a 1448 x 1072 grid, the same body and the same weight, but the BW keeps a plain E Ink Carta 1300 HD panel. No color layer lies between the ink and the front light, so black text lands on the cleanest page Kobo makes at this size.
Around that panel it is a plain, waterproof slab. ComfortLight PRO shifts the front light toward amber at night. The IPX8 rating covers an hour in two meters of water, and Libby borrowing from a public library runs on the reader itself. EPUB opens natively, alongside PDF, MOBI, CBZ and CBR, so books bought outside Kobo's store need no conversion. Dark Mode flips the page to white text on black.
Kobo promises up to 53 days of reading at half an hour a day, with the front light turned down to a tenth and the radios off. The Clara Colour's 42 days come from a test with the light three times as bright. Because the conditions differ, the gap between the two ratings says less than it seems, and the black versions of both use a cell of the same size.
The processor is a step down from its sibling: Kobo lists a 1.0 GHz chip for the BW and a dual-core 2.0 GHz one for the Clara Colour. There is no stylus support and no Dropbox or Google Drive connection, so files from outside the store go on over the USB-C cable.

Editor’s note
The Clara Colour's filter takes light and contrast from every page to show color on a few. For a library of novels that makes the BW the better Clara, and its slower processor counts for least on plain text, which is the BW's whole job.
Amazon's redesigned Kindle, on sale since October 1, 2026, is the other six-inch choice. Best Buy's listing marks it as not waterproof, and the base model shows ads until you pay Amazon to remove them. The Clara BW reads EPUB without conversion and borrows from Libby on the device. If your books already come from Amazon, those advantages count for little, since Kindle books stay on Kindle devices and apps.
Kobo sells audiobooks and the Clara BW plays them, but there is no speaker and no headphone jack. Every listen starts with pairing Bluetooth headphones or a speaker, which is where I'd hesitate if audiobooks are a nightly habit. One-handed readers lose out too, because Kobo keeps physical page-turn buttons for the Libra Colour and the Sage.
Regret is most likely for someone who buys it for manga or illustrated textbooks to save the difference. A cover or a colored diagram turns gray here, and no setting changes that. For text the trade runs the other way.

The bottom line
The Kobo Clara BW earns a VS Score of 55, above the median of the 4 basic prose e-readers it is measured against (a score of 50 is level with that median).
- Who it’s for
- Novel readers who borrow through a public library and want a waterproof six-inch reader with the cleanest black-and-white page Kobo sells.
- Who should look elsewhere
- Anyone who reads comics, color manga or illustrated textbooks, and anyone who wants to write on the page. The Libra Colour adds a color screen and stylus support.
- The trade-off that matters
- Dropping the color filter gives a brighter, higher-contrast page, and it turns every cover and comic panel gray.
- The main alternative
- Kobo Clara Colour, the same body and size with a Kaleido 3 panel, which is the better buy if any real part of your library is in color.
