Boox Page Screensaver Size: 1264 × 1680 px

Choosing an Image for the Boox Page

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.

How to Set a Custom Screensaver on the Boox Page

Boox devices run Android, so the sleep screen is set from the system settings — point the screensaver option at an image you have copied onto the device. Boox also runs KOReader, which has its own wallpaper setting.

1. 1

   Resize the image

   Size the image to your Boox device's exact screen resolution using the resizer above, then download it.

2. 2

   Copy it to the device

   Transfer the image over USB, or use the device's own cloud sync or file transfer app to get it into internal storage.

3. 3

   Open the screensaver settings

   In the Boox system settings, find the power or screensaver section and choose the option to use a custom image or image folder.

4. 4

   Select your image

   Browse to the image you copied across and select it, then sleep the device to confirm.

Note: Boox firmware changes often and menu names vary between models and versions, so the exact wording of the screensaver setting may differ from the description above.

Boox Page Screensaver FAQ

What size should a Boox Page screensaver be?

A Boox Page screensaver should be 1264 x 1680 pixels — the device's exact panel resolution. That is a 7-inch screen with a 1:1.33 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 Boox Page. 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 Boox Page support custom screensavers?

Boox devices run Android, so the sleep screen is set from the system settings — point the screensaver option at an image you have copied onto the device. Boox also runs KOReader, which has its own wallpaper setting.

Can I use the same image on other e-readers?

Yes. 6 other supported e-readers use the same 1264 x 1680 panel as the Boox Page: Kindle Paperwhite (12th Gen), Kindle Oasis (3rd Gen), Kindle Colorsoft, Kobo Libra 2 / Libra H2O, Kobo Libra Colour, PocketBook Era. One correctly sized image works on all of them without re-cropping.
