One would think that 1280×800 screen calls for wallpaper of such dimensions. But apparently Google is set on shaking logic of wallpapers in Android, because it’s harder to figure out by version.
There is a lot of advice floating on trying to hammer wallpaper into tablet with various apps from market, but really it works great to use high resolution image and crop it to work without rescaling.
I am dealing with Samsung 8.9″ tablet with 1280×800 screen and Android 3.1. Your mileage may vary.
Image crop
When you want to set image as wallpaper, instead of going with it or asking how do you want it to fit – Android gives you confusing cross-shaped crop area to apply. Pretty much anything I have tried to feed it at first ended up horribly blurry and cut down.
Since wallpaper should fit screen 1:1 pixel for best looks the first issue to use image of correct dimensions. Bundled wallpapers look great and crisp, but there are too few of them.
Required dimensions
After some googling turned out that native wallpaper resolution is 1920×1408. See any logic connecting it to 1280×800 of real screen resolution? Neither do I.
Effectively this means that you won’t find much of such wallpapers around and will need to crop larger image in advance. And will need something really huge to crop, because even 1920×1080 of HD resolution is too small vertically.
Visible areas
Next, let’s deal with that cross shape. Wallpaper is never completely visible on screen. Instead:
- two main areas are visible in portrait and landscape mode respectively;
- areas to the left and right become visible when scrolling home screen;
- area to the top becomes visible in applications menu;
- area to the bottom becomes visible in home screen settings menu;
- corners will be pretty much unreachable.
I’ve made a template to illustrate (clickable for full size version):
So despite total image size, only 800×800 central section will be visible in both screen modes.
After you find image of sufficient dimensions you can use template to precisely determine how to crop it best, before uploading to device:
And then, when device prompts you to crop, carefully drag out crop area to cover all of image both vertically and horizontally:
As result you will get perfect fit – no rescaling and crisp look of original wallpaper.
Overall
To sum it up – for best results you need large original image with compact central point. Asymmetrical wallpapers won’t work nicely at all, portrait mode won’t even scroll very far to the sides.
How much longer will we eat pocket computing bullshit?

After reading your post I was searching for a nice “Good size” wallpaper.. But I just get really frustrated with the bad an low quality websites Google.nl keeps presenting when doing a search for “wallpaper + anything”…
@C. Tassen
Google is not too good for searching for wallpapers. It’s better to find a good wallpaper site and stick with it, but they tend to specialize in images on specific topic so there is no one true site to use.
Interfacelift has a lot of high-res wallpapers, but they mostly are photo/nature or abstract.
Thank you for clearing this up — especially the part about the “native” dimensions of 1920×1408, which is necessary to work in both landscape and portrait positions and to allow for the side-scrolling effect.
Now if I could only find some nice wallpaper images in those dimensions!
