2560 × 1440 channel art — and a reminder that only the middle survives on a phone.

2560 × 1440
Channel art is the one banner that is deliberately cropped by the platform. You upload 2560 × 1440, and a television shows nearly all of it, a desktop browser shows a wide strip through the middle, and a phone shows only a small central rectangle — roughly 1546 × 423 of your 2560 × 1440. That centre block is the only part guaranteed to be visible everywhere.
So the useful way to think about this crop is in two layers. The outer 16:9 frame is what you upload and what fills a TV screen; the middle fifth is where the channel name, the tagline and anything else that must be read have to live. Text drifting toward the edges is not smaller on mobile — it is simply gone. Frame the crop so the subject sits centred, then check it against the safe strip before you upload.
three steps
PNG, JPG or WebP. It is decoded in the page — nothing is uploaded, so nothing waits on a connection.
The crop box is already locked to the 16:9 shape. Drag it over the part that matters and resize it from any corner; the pixel size is shown as you go.
The export is exactly 2560 × 1440. Keep anything essential inside the central strip, since that is all a phone will show.
quick answers
2560 × 1440 pixels is the recommended upload, a 16:9 ratio. YouTube then crops it per device, so the full image is only seen on a TV.
The central region of roughly 1546 × 423 pixels, which stays visible on every device including phones. Logos and text belong inside it; decoration can spill outside.
Because it is — that is by design, not a bug in your upload. The same file is cropped tighter the smaller the screen gets, so a design that fills the full 16:9 will always lose its edges on a phone.
No. The crop and the resize happen in your browser, and the file never leaves your device.
