2048 x 1152 Resizer
2048 x 1152 pixels is the minimum size YouTube accepts for channel banner art (2560 x 1440 is the recommended upload), and the same 16:9 canvas Tumblr recommends for blog headers. It's a banner working size: big enough to pass upload checks, with the usual caveat that only the centre of the image is visible on every device.

YouTube's Minimum Banner Size
YouTube rejects channel banner uploads smaller than 2048 x 1152, making this the floor for channel art; the platform’s recommended upload is the larger 2560 x 1440.Meeting the minimum gets the banner accepted — but the safe-area rules still apply, since desktop and mobile only display the middle of the canvas.
Tumblr's Recommended Header
Tumblr recommends the same 2048 x 1152 (16:9) size for blog headers, so one export can serve both platforms.Keep the file under platform upload limits and preview the header at phone width — the sides of the canvas disappear first.
Designing Inside the Safe Area
Banner surfaces show the full 16:9 canvas only on large screens; desktop and mobile crop to a shorter, centred strip.Place logos, titles, and anything essential in the central region and let the outer thirds carry background texture only.
