The two sell at the same starting price at each tier on the vendor pages ($149.99 base Kindle per Amazon’s 2026-10-01 announcement and NOOK GlowLight 4 per B&N pages seen 2026-10-26; $199.99 Paperwhite preorder and NOOK GlowLight 4 Plus), so price does not decide it. Pick by where you buy books: Kindle if you read in Amazon’s store or want Kindle Unlimited; NOOK if you buy from Barnes & Noble or side-load EPUB and PDF files.
At ReadNext, we built this comparison from what Amazon and Barnes & Noble publish; we did not test any device.

Kindle vs NOOK: Pricing and Ecosystem Value
In our internal price comparison, we matched each NOOK to the Kindle at the same tier using the prices on the vendor pages (B&N pages seen 2026-10-26, Amazon announcement 2026-10-01) and found a $0.00 gap at both tiers. The method is the on-page price table below. Amazon listed the base Kindle at $149.99 on its Kindle lineup announcement published 2026-10-01. Barnes & Noble listed the base NOOK GlowLight 4 at $149.99 on the Barnes & Noble NOOK GlowLight 4 product page on 2026-10-26.
At the $199.99 tier, the two brands are tied again. The Kindle Paperwhite was announced at $199.99 on 2026-10-01 as a preorder shipping from late October 2026. The larger NOOK GlowLight 4 Plus listed at $199.99 on the Barnes & Noble NOOK GlowLight 4 Plus product page on 2026-10-26. Amazon’s announcement lists the Signature Edition at 32GB and $249.99.
B&N Premium Members save 10% on NOOK devices; see the Barnes & Noble NOOK GlowLight 4 product page. Barnes & Noble also sells NOOK Protect plans, priced at $24.99 for two years or $43.99 for three years on the GlowLight 4.

Amazon offers Kindle Unlimited, providing access to over 5 million digital titles, plus thousands of audiobooks and magazines per the Amazon Kindle Unlimited subscription page. Amazon’s page did not display a price; it varies, so verify on the Amazon page. See Is Kindle Unlimited worth it?. Barnes & Noble promotes an audiobook credit plan where 1 credit gets you 1 audiobook from over 200,000 titles; we found no NOOK equivalent to Kindle Unlimited on the pages we read.
Display Hardware and Lighting
The base Kindle features a 6-inch flush-front display, while the NOOK GlowLight 4 uses a 6” 300-dpi screen protected by a glare-resistant, scratch-resistant, and fingerprint-resistant lens.
Lighting differs at the $149.99 entry price. The NOOK GlowLight 4 features built-in GlowLight illumination alongside Night Mode, which casts a warm sepia tone across the display. In contrast, third-party reporting from The eBook Reader’s Kindle lineup overview notes that the $149.99 base Kindle lacks a warm front light. Readers who want a warm sepia Night Mode at the $149.99 tier receive that feature on the NOOK GlowLight 4.
Barnes & Noble lists the NOOK GlowLight 4 Plus with a flush-front 7.8-inch display; the Paperwhite’s screen size is not in the sources we read. The Paperwhite lists an adjustable warm light; the GlowLight 4 Plus lists GlowLight and Night Mode.
Alternative variants exist within the NOOK catalog. Barnes & Noble sells the NOOK GlowLight 4 Ocean Teal Edition, which provides the identical 6-inch hardware package in an alternate shell color. Barnes & Noble also sells the NOOK GlowLight 4e, which includes 8GB of storage and an adjustable front light, with no mention of Night Mode on its listing.
Physical Design, Buttons and Waterproofing
The NOOK GlowLight 4 turns pages by swiping or with physical buttons, and the GlowLight 4 Plus lists physical page-turn buttons too. The Amazon pages we read do not mention physical page-turn buttons.
Barnes & Noble provides no waterproof rating for the base NOOK GlowLight 4 on its product specifications table. Third-party reporting says the base Kindle is not waterproof. Readers who read near water should look at the $199.99 tier.
At the $199.99 tier, the Paperwhite is described as waterproof, while the NOOK GlowLight 4 Plus is IPx7 certified. Barnes & Noble says the NOOK GlowLight 4 Plus is waterproof in fresh water, protecting the device against fresh water immersion for up to 30 minutes at a maximum depth of 1 meter (3.28 feet). Barnes & Noble says to avoid immersion in saltwater or other liquids and to keep the USB port completely dry before use. Amazon’s 2026-10-01 announcement describes the Kindle Paperwhite as waterproof.
B&N lists a soft-touch finish for the NOOK GlowLight 4. NOOK weight and dimensions are not published on the pages we read.
Battery Life and Charging Hardware
Amazon rates the base Kindle for up to 6 weeks of battery life on a single charge. For the Kindle Paperwhite, Amazon claims up to 12 weeks of battery life on a single charge.
Barnes & Noble states that users can read for weeks on a single charge with the NOOK GlowLight 4. Barnes & Noble bases its one-month operational estimate on 30 minutes of reading per day, 1 page refresh per minute, GlowLight brightness set at 10%, and wireless connectivity turned off. Results vary.
The NOOK GlowLight 4’s USB-C connector charges the battery and connects to a computer.
Storage Capacity and File Compatibility
The NOOK GlowLight 4 comes standard with 32GB of internal storage, with Barnes & Noble specifying that 29.1GB is available for NOOK Store content and side-loaded content. B&N also lists an optional microSD card. The base Kindle lists 16GB of storage.
At the $199.99 price level, internal storage allocations show a similar pattern. The NOOK GlowLight 4 Plus lists 32GB of memory with an optional microSD card. The standard Kindle Paperwhite includes 16GB of internal storage. Readers who want 32GB on an Amazon device must spend $249.99 for the Kindle Paperwhite Signature Edition.

Which E-Reader Fits Your Habits
With equal prices, choose the store you already buy from. Two things can override that: waterproofing (only the Paperwhite and the NOOK GlowLight 4 Plus are described as waterproof) and Kindle Unlimited versus B&N’s audiobook credit plan. This comparison is calculated from vendor-page prices and specs; we did not test any device. Verify prices on the Barnes & Noble NOOK GlowLight 4 product page and the Amazon Kindle lineup announcement.
Choose a Kindle if you buy from Amazon’s bookstore, want Kindle Unlimited, or want Amazon’s stated battery rating of up to 12 weeks on the Paperwhite. The base Kindle provides 16GB of storage and up to 6 weeks of battery life for $149.99. The $199.99 Kindle Paperwhite is described as waterproof and rated for up to 12 weeks on a single charge. Libby reads most library books on a Kindle in the U.S. For another brand, see Kindle vs Kobo. To choose within Kindle, see Kindle vs Kindle Paperwhite.
Choose a NOOK if you prefer purchasing books from Barnes & Noble, value physical page-turn buttons, or maintain a personal library of DRM-protected EPUB files. At $149.99, the NOOK GlowLight 4 includes 32GB of storage, expandable microSD support, and a warm sepia Night Mode; the base Kindle lists 16GB and, per third-party reporting, no warm front light. If you spend $199.99, the NOOK GlowLight 4 Plus delivers a 7.8-inch screen, IPX7 water protection, and a 3.5mm headphone jack for wired audiobook listening.

Who This Is Not For
The base NOOK GlowLight 4 and the base Kindle are not suitable for people who read near water. Neither entry-level device includes a waterproof rating. Readers who require water protection must step up to the $199.99 tier for the Kindle Paperwhite or the NOOK GlowLight 4 Plus.
Readers with a large library already bought in Amazon’s Kindle store may prefer to stay on Kindle hardware; this page did not check whether Kindle purchases can be read on a NOOK.
What Would Change Our Answer
Sale prices and member discounts would change the price comparison, and a verified NOOK library-lending option would change the library answer.
