Kobo vs NOOK depends on which store you buy from and which feature you need. The NOOK is cheaper at both tiers we paired. The NOOK GlowLight 4 lists at $149.99 against $159.99 for the Kobo Clara BW. The NOOK GlowLight 4 Plus lists at $199.99 against $259.99 for the Kobo Libra Colour. All four prices were seen on 2026-11-04. Pick Kobo for waterproofing at the entry price, for color, or for library borrowing through OverDrive and Libby. Pick NOOK if you buy from Barnes & Noble, want the lower sticker price, or want 32GB at the entry tier. Check current prices on the Kobo collection page and the Barnes & Noble GlowLight 4 page before you buy.
At ReadNext, we calculated these gaps from vendor pages and tested no device.
Kobo or NOOK at Each Price Tier
The NOOK is cheaper than the Kobo at both tiers we paired, but only the first pair shares a 6-inch screen. The Kobo Clara BW lists at $159.99, and the NOOK GlowLight 4 lists at $149.99, both seen on 2026-11-04. Both have a 6-inch screen. The Kobo Libra Colour lists at $259.99, and the NOOK GlowLight 4 Plus lists at $199.99, also seen on 2026-11-04. The Libra Colour has a 7-inch color screen, and the pages we read do not describe either NOOK device as color, so the larger pair is not like-for-like.
At the entry tier, the question is whether a $10.00 saving is worth giving up listed waterproofing. The Kobo Clara BW carries an IPX8 rating, and the GlowLight 4 page lists none. Readers who plan to read near water should weigh that difference before they weigh the price.
How We Calculated the Price Gaps
We matched each NOOK to the nearest Kobo tier using the prices on the product pages. At the 6-inch tier, the GlowLight 4 is $10.00 below the Clara BW ($159.99 minus $149.99), or 6.3% of the Clara BW price. At the larger tier, the GlowLight 4 Plus is $60.00 below the Libra Colour ($259.99 minus $199.99), or 23.1% of the Libra Colour price. The larger-tier figure compares a black-and-white NOOK against a color Kobo, so treat it as a price difference, not a like-for-like verdict.
Barnes & Noble says Premium Members save 10% off NOOK tablets, eReaders and accessories. If that discount applies, the GlowLight 4 falls to $134.99 ($149.99 minus $15.00), and the gap to the Clara BW widens to $25.00. The GlowLight 4 Plus falls to $179.99 ($199.99 minus $20.00), and the gap to the Libra Colour widens to $80.00. The Kobo pages we read state no member discount.
The Kobo Clara Colour lists at $179.99 on the Kobo collection page, seen 2026-11-04. Its product page, fetched 2026-10-01, describes a 6-inch color E Ink Kaleido 3 screen, 16GB of storage and an IPX8 rating. That price sits $20.00 below the GlowLight 4 Plus and $30.00 above the GlowLight 4.

Read the first two price columns as one pair and the last two as another. The Libra Colour is a color device, and the pages we read do not describe the GlowLight 4 Plus as color. Check current prices on the Kobo collection page and the Barnes & Noble GlowLight 4 page.
Waterproofing and the Stated Limits
The Kobo Clara BW and Kobo Libra Colour both carry an IPX8 rating, which Kobo describes as waterproof for up to 60 minutes in up to 2 meters of water. The Clara BW is the only one of the two at the entry price.
The NOOK GlowLight 4 page lists no waterproof rating. The GlowLight 4 Plus page, fetched 2026-10-26, lists an IPx7 certification, meaning it is waterproof in fresh water for up to 30 minutes at a maximum depth of 1 meter (3.28 feet). That page also says to avoid immersion in saltwater or other liquids.
Set side by side, the Kobo entries list twice the depth (2 meters against 1 meter) and twice the time (60 minutes against 30) of the GlowLight 4 Plus. Those are the printed numbers, so compare them directly rather than comparing the rating letters. At or below $159.99, the Clara BW is the only device here with a listed waterproof rating.
Screen, Front Light and Page Turns
The Kobo Clara BW has a 6-inch E Ink Carta 1300 touchscreen at 1448 x 1072 resolution. Its ComfortLight PRO adjusts brightness and color temperature. The NOOK GlowLight 4 has a 6-inch screen with GlowLight illumination and Night Mode. You turn pages by swiping or with physical buttons.
The Kobo Libra Colour has a 7-inch color E Ink touchscreen with physical page-turn buttons. The fetched page does not list a front light for the Libra Colour. The NOOK GlowLight 4 Plus is a 7.8-inch reader with GlowLight and Night Mode, and it turns pages with physical buttons or swiping.
Color is the main screen difference here. The Libra Colour and the Clara Colour are the only color devices in our facts, and both are Kobo models. The NOOK pages describe no color screen. A reader who needs color should look at the Kobo side first.
Storage, Battery and Subscription Costs
The Kobo Clara BW has 16GB of storage, which Kobo says holds up to 12,000 eBooks or 75 Kobo Audiobooks. The Libra Colour has 32GB, which Kobo says holds up to 24,000 eBooks or 150 Kobo Audiobooks. The GlowLight 4 and GlowLight 4 Plus each list 32GB (gigabytes). At the entry tier, the GlowLight 4 offers twice the storage of the Clara BW (32GB against 16GB).
Kobo rates the Clara BW at up to 53 days per charge under its stated conditions: 30 minutes of reading a day, front light at 10%, and Wi-Fi and Bluetooth off. The Libra Colour page says weeks of battery life, with no day count. The GlowLight 4 page says it reads for weeks on a single charge, and the GlowLight 4 Plus page lists no battery figure. The NOOK page gives no test conditions, so the 53-day figure cannot be compared directly with it.
The Kobo Plus plans page lists three US plans as of 2026-10-01: Read and Listen at $9.99 a month, Read at $7.99 a month, and Listen at $7.99 a month. New subscribers get the first 14 days free. Twelve months of Read and Listen costs $119.88, and twelve months of Read alone costs $95.88 ($7.99 times 12). We did not re-fetch those plans on 2026-11-04.
The NOOK pages we read list no reading subscription equivalent to Kobo Plus.
Audiobooks and Library Borrowing
The Kobo Clara BW and Libra Colour both have built-in Bluetooth for Kobo Audiobooks. The GlowLight 4 Plus, per its page fetched 2026-10-26, streams or downloads audiobooks wirelessly and plays them through Bluetooth or a 3.5mm headphone jack. It is the only device here with a wired headphone option listed. The GlowLight 4 page lists no audiobook support.
The Kobo Clara BW page says you can borrow eBooks from your local library, but it does not name OverDrive. The Libra Colour page says you can borrow eBooks directly from your local library with OverDrive and Libby integration. That integration is available only in select countries, and availability varies by library location. If you want setup steps, see How to use Libby.
The pages we read do not say whether NOOK devices borrow library books, so we do not state either way. Ask your library and read the Barnes & Noble GlowLight 4 page before you buy a NOOK. If library borrowing decides your purchase, the Libra Colour is the only Kobo here whose page names OverDrive and Libby.
File Formats and Book Sources
The Kobo pages list 15 file formats the device reads natively: EPUB, EPUB3, FlePub, PDF, MOBI, JPEG, GIF, PNG, BMP, TIFF, TXT, HTML, RTF, CBZ and CBR. The Clara BW and the Libra Colour share this list.
The GlowLight 4 and GlowLight 4 Plus pages do not list a file format set, so we cannot say which formats the NOOK devices read natively. If you already hold books in a format outside the Kobo list, check the Barnes & Noble GlowLight 4 page for NOOK formats before you buy.
Barnes & Noble’s GlowLight 4 page says browsing over 5 million eBooks is possible. That is Barnes & Noble’s own claim, and an earlier fetch on 2026-10-26 showed 4.5 million or more, so the count changes between fetches. The Kobo pages we read give no store size.
Who This Pairing Does Not Serve
Readers who need a color NOOK should look elsewhere. The pages we read describe no NOOK color screen, so a color reader is choosing among Kobo models: the Libra Colour at $259.99 or the Clara Colour at $179.99.
Readers who want a 7.8-inch screen below $199.99 should look elsewhere. The GlowLight 4 Plus is the only 7.8-inch device here, and it lists at $199.99. The Kobo models here have 6-inch and 7-inch screens.
Readers who need the NOOK file-format list or a NOOK library answer will not find either one here. The pages we read do not provide either one. Readers comparing a Kindle should start with Kindle vs Kobo or Kindle vs NOOK.
What Would Change Our Answer
A price change would move the gaps. The prices here were seen on 2026-11-04, and a sale or a new list price would change the $10.00 and $60.00 figures.
Stock changes too. The GlowLight 4 page showed “In stock” and “Ships in 1-2 days” on 2026-11-04, after an earlier fetch showed an out-of-stock line.
A published NOOK library-borrowing feature or a published NOOK file-format list would fill two gaps in the table. A published waterproof rating for the GlowLight 4 would change the entry-tier answer, because the Clara BW would no longer be the only waterproof device at $159.99 or below. A NOOK color device would change the color answer.
What the Product Pages Do Not Publish
Check these on the Kobo collection page and the Barnes & Noble GlowLight 4 page before you buy:
- NOOK weight and dimensions.
- Exact battery hours for the Kobo Libra Colour, which says only weeks, and for both NOOK devices.
- A battery figure for the NOOK GlowLight 4 Plus.
- Whether NOOK devices borrow library books through OverDrive or Libby.
- Which file formats the NOOK devices read natively.
- A NOOK reading subscription equivalent to Kobo Plus.
- Today’s sale prices, bundles and stock beyond the 2026-11-04 snapshot.
- The size of the Kobo store.
- A front light for the Kobo Libra Colour.
Which E-Reader Fits Your Purchase
Neither brand wins on every listed feature. Choose by the store you buy from and the one feature you will use most.
Pick Kobo if you want waterproofing at the entry price, since the Clara BW lists IPX8 at $159.99 and the GlowLight 4 lists no rating at $149.99. Pick Kobo if you want color, which the Libra Colour (7-inch, $259.99) and the Clara Colour (6-inch, $179.99) provide. Pick Kobo if library borrowing through OverDrive and Libby matters to you, since the Libra Colour page names that integration in select countries. Pick Kobo if the 15 listed file formats are your main requirement.
Pick NOOK if you buy from Barnes & Noble and want the lower sticker price. The GlowLight 4 is $10.00 below the Clara BW, and the GlowLight 4 Plus is $60.00 below the Libra Colour, though that larger pair does not match on color. Pick NOOK if you want 32GB at the entry tier, twice the Clara BW’s 16GB. Pick NOOK if you need a 7.8-inch screen or a wired headphone jack, both on the GlowLight 4 Plus at $199.99.
