Kobo Nia Screensaver Size: 758 × 1024 px
The Kobo Nia screensaver and wallpaper size is 758 × 1024 pixels. That is a 6-inch e-ink panel with a 1:1.35 aspect ratio at 212 ppi. Export at exactly those dimensions and the image fills the screen with no stretching, cropping or black bars.
At 212 ppi this is the lowest-density e-reader on this list, tied with the Nook GlowLight 4e, which uses the same 758 x 1024 panel. Fine detail and small text will look soft, so favour bold shapes and strong contrast over intricate illustration.
Use the resizer below to crop any photo or artwork to those exact dimensions — it opens with the Kobo Nia already selected, runs entirely in your browser, and never uploads your image anywhere.

Choosing an Image for the Kobo Nia
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 212 ppi this is a comparatively low-density panel. Intricate detail and small text will look soft, so bold shapes, heavy line weights and strong tonal separation give much better results.
- 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.

How to Set a Custom Screensaver on the Kobo Nia
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.
- 1
Resize the image
Size the image to your Kobo's exact screen resolution using the resizer above, then download it.
- 2
Connect the Kobo by USB
Plug the Kobo into your computer and tap Connect on the prompt that appears on the device.
- 3
Create the screensaver folder
Open the hidden .kobo folder on the Kobo drive and create a folder named exactly `screensaver`, all lowercase. On Windows enable Show hidden files; on macOS press Command + Shift + period in Finder.
- 4
Copy your images across
Copy the resized images into .kobo/screensaver, then safely eject the Kobo.
- 5
Enable the sleep-screen settings
On the Kobo, open Settings > Energy saving and privacy and enable both "Show current read" and "Show book covers full screen".
Note: The folder name is case-sensitive. If the screensaver does not appear, re-check the folder spelling and confirm both settings are enabled.
Devices That Use the Same 758 × 1024 Size
One other supported e-reader uses the same panel resolution, so a single image works on both.
Kobo Nia Screensaver FAQ
- What size should a Kobo Nia screensaver be?
- A Kobo Nia screensaver should be 758 x 1024 pixels — the device's exact panel resolution. That is a 6-inch screen with a 1:1.35 aspect ratio at 212 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 Nia. 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 Nia 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.
- Can I use the same image on other e-readers?
- Yes. 1 other supported e-reader uses the same 758 x 1024 panel as the Kobo Nia: Nook GlowLight 4e. One correctly sized image works on all of them without re-cropping.
