If you want an e-reader that can travel in a pocket, the BOOX Palma is a strong candidate—but the available information does not establish it as the smallest e-reader, or confirm the model behind the original first-person headline. “Smallest” depends on which devices you compare and which pocket you need to fit. BOOX lists the Palma at 159 × 80 × 8.0 mm and says it supports third-party apps, including Kindle.
What does “smallest e-reader” mean?
The answer changes with the comparison set. You might mean the smallest model from a particular brand, the smallest widely available dedicated e-reader, or simply a device that fits comfortably in your pocket. Those are different claims, and the available sources do not establish a definitive winner across all current readers.
Pocket fit is personal, too: it depends on the device’s footprint, whether you add a case, the pocket’s dimensions, and how comfortable you find reading on a smaller screen. No controlled carry test or author experience is established here.
Why the BOOX Palma is a plausible pocket option
BOOX lists the Palma’s dimensions as 159 × 80 × 8.0 mm (6.3 × 3.1 × 0.31 inches). Its phone-shaped footprint makes it a reasonable device to consider if pocketability is the priority. Those dimensions alone do not prove that it is the smallest available e-reader or that it will fit a particular pocket. BOOX’s product page also describes support for third-party apps from Google Play, naming Kindle among its examples.

The magnetic pogo-pin charging design maintains a clean, minimalist appearance while supporting convenient daily charging.
App compatibility can make a compact device useful if you already read through a preferred service, but compatibility is not proof that every app will feel or work like it does on a dedicated reader. The product information establishes that Kindle is among the supported app examples; it does not establish an identical reading experience.
How the Palma compares with a small dedicated Kindle
The figures below are not a controlled head-to-head test. BOOX supplies the Palma dimensions, while a secondary comparison table reports selected specifications for the 2024 Kindle. The Kindle’s body dimensions are not established by that table, so its pocket fit cannot be compared directly here.

- Measure your pocket: Compare its usable opening and depth with the device’s listed height and width. Consider the case separately, since it adds bulk.
- Judge the reading area: A compact body can be easier to carry but may provide less room for text. Try to assess the screen size in person if reading comfort is important.
- Check your reading apps: The Palma’s product page names Kindle as a supported third-party app. Confirm that the services and features you rely on are available for your needs; app support alone does not establish that every feature matches a dedicated reader.
- Decide what would be a dealbreaker: That depends on your priorities—such as pocket fit, screen size, or access to your preferred reading service. No verified first-person account or two specific dealbreakers is established by the available sources.
What current recommendations can—and cannot—tell you
TechRadar’s 2026 e-reader roundup describes the Palma 2 as phone-sized and pocketable, and also includes more conventional options such as the Kindle Paperwhite and Kobo Clara BW. This is useful context for the range of devices readers may consider, but it is a secondary roundup, not an apples-to-apples pocket-fit test. It does not establish which device is smallest for every reader or which one will suit a particular pocket.
