In Edit Mode Sweeter Home blocks align into a 16×16 grid. Due to different screen resolutions this means the actual pixel size of each grid division is different depending on the device you’re using.
To help those of you who like to create custom images for their themes, and want to get your image alignment perfect, attached are PSD (Photoshop) files with a graphical (pixel) grid on a layer as well as actual Photoshop guides already laid out for you. At the moment I’m supplying portrait only.
Note: I’m fairly sure these will open with grids included in The GIMP, which is free.
An important note: these PSD files are NOT the same size as the screen resolution of your device. But this is correct because they exclude the pixels used by the notification bar in Android.
