Questions about the Boox Note Air 4C screen
What is the screen size of the Boox Note Air 4C?
The Boox Note Air 4C has a 10.3-inch display. In CSS the viewport measures 1860 × 2480 px in portrait, and the panel itself has 1860 × 2480 physical pixels at 300 PPI.
What resolution should I design for on the Boox Note Air 4C?
Design at 1860 × 2480 and export assets at 1×. That gives you 1860 × 2480 px images, which is exactly what the panel renders. Designing directly at 1860 × 2480 means every measurement is 1 times larger than the CSS values you will write.
