Are the platform dimensions current?
We use the dimensions currently recommended by each platform. Platform requirements change occasionally, so presets are data-driven and easy to update.
Will the image be cropped?
In Fit mode the entire image is scaled to fit inside the preset without cropping. In Fill mode it is scaled to cover the frame and cropped to match exactly.
