YouTube banner size checker

YouTube Help sets the minimum banner upload at 2048 x 1152 pixels at 16:9 and recommends 2560 x 1440, especially for TV. At the minimum size, text and logos belong inside a 1235 x 338 pixel safe area, because other screens crop the rest. The file has to be 6 MB or smaller.
