Recommended Asset Sizes
Banner Logo - 400x300
Mobile Banner Logo - Themes made with the theme editor (i.e. any Foundation-based theme) and some custom themes don't use this setting. (taken from the dashboard)
Banner Image - 1000x400
Favicon - these are usually SVG files, so the size isn't an issue; if using a GIF, we recommend 128x128
Touch Icon - 152 pixels
Share Image - at least 50×50, but we recommend 200×200
