PocketBook InkPad 4 / Color 3 Screensaver Size: 1404 × 1872 px
The PocketBook InkPad 4 / Color 3 screensaver and wallpaper size is 1404 × 1872 pixels. That is a 7.8-inch e-ink panel with a 1:1.33 aspect ratio at 300 ppi. Export at exactly those dimensions and the image fills the screen with no stretching, cropping or black bars.
At 7.8 inches with a 1404 x 1872 panel, this packs the resolution of a 10-inch device into a smaller screen, so it renders fine detail unusually crisply for its size.
Use the resizer below to crop any photo or artwork to those exact dimensions — it opens with the PocketBook InkPad 4 / Color 3 already selected, runs entirely in your browser, and never uploads your image anywhere.

Choosing an Image for the PocketBook InkPad 4 / Color 3
Getting the pixel dimensions right is only half of it. This panel has its own characteristics, and they change what kind of source image holds up on screen.
- At 300 ppi this panel resolves fine detail well. Thin linework, small lettering and subtle tonal gradients all survive, so detailed illustration and photography both work.
- The 1:1.33 ratio is close to a standard portrait photograph, so most vertical photos crop to fit with little loss. Landscape source images will lose a lot of their width — crop deliberately rather than letting the frame decide.
- E-ink is greyscale, so colour contrast disappears on screen. Check that your image still separates into clear light and dark areas once colour is removed — two colours of similar brightness will merge into one flat tone.
