You can now pre-order BOOX’s tiniest e-reader yet

Over the last several months, tiny e-readers have become more common, especially the ones that stick to the back of a phone with built-in magnets. The allure is simple: tiny e-readers, such as the Xteink X4, take up minimal space in your pocket or backpack while also offering a break from frantically refreshing hi-res displays on phones. BOOX (officially Onyx BOOX), one of the biggest names in e-readers, is entering the tiny-screen segment with an entire “Tiles” series. The first, BOOX Picco, was teased in July, revealed at IFA 2026, and is now up for pre-orders.

While BOOX Palma has been the smallest device from the brand, the Picco is shrunk further down to a screen size of under four inches and a footprint no bigger than a credit card. More accurately, it features a 3.97-inch ePaper touch display with a resolution of 480 x 800 pixels. For a screen of its size, that’s fairly sharp. Like BOOX’s bigger models, it lets you adjust the frontlight’s warmth for more comfortable nighttime reading.
