Kobo Clara BW Screensaver Size: 1072 × 1448 px
The Kobo Clara BW screensaver and wallpaper size is 1072 × 1448 pixels. That is a 6-inch e-ink panel with a 1:1.35 aspect ratio at 300 ppi. Export at exactly those dimensions and the image fills the screen with no stretching, cropping or black bars.
The Clara BW shares its 1072 x 1448 panel with the Clara 2E, the Clara HD, several Kindles and the Nook GlowLight 4, so the same image file works across all of them.
Use the resizer below to crop any photo or artwork to those exact dimensions — it opens with the Kobo Clara BW already selected, runs entirely in your browser, and never uploads your image anywhere.

Choosing an Image for the Kobo Clara BW
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 1:1.35 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.

Kobo Clara BW Screensaver FAQ
- What size should a Kobo Clara BW screensaver be?
- A Kobo Clara BW screensaver should be 1072 x 1448 pixels — the device's exact panel resolution. That is a 6-inch screen with a 1:1.35 aspect ratio at 300 ppi. Matching these dimensions means the image fills the screen with no stretching, cropping or black bars.
- What format should the image be in?
- PNG or JPG both work on the Kobo Clara BW. PNG keeps sharp edges cleaner on text and line art, which suits e-ink. Because the screen is greyscale, high-contrast images with simple composition reproduce far better than busy colour photographs.
- Does the Kobo Clara BW support custom screensavers?
- Kobo reads sleep-screen images from a folder you create yourself. Put your resized images in a folder named exactly `screensaver` inside the hidden `.kobo` folder, then enable the two sleep-screen settings.

- Yes. 5 other supported e-readers use the same 1072 x 1448 panel as the Kobo Clara BW: Kindle (11th Gen), Kindle Paperwhite (10th Gen), Kobo Clara 2E / Clara HD, Kobo Clara Colour, Nook GlowLight 4. One correctly sized image works on all of them without re-cropping.
