What YouTube Actually Does to Your Banner
YouTube does not scale your channel art down evenly. Instead, it uploads a single 16:9 canvas (2560 × 1440 px) and carves out different viewports depending on the viewer's device.
2560 × 1440 px
Full 16:9 canvas displayed exclusively on smart TVs and video game consoles.
2560 × 424 px
Wide horizontal strip. The top ~35% and bottom ~35% are cropped off by browser layouts.
1855 × 424 px
Horizontal ribbon crop centered on the safe zone. Sides are clipped compared to desktop.
1546 × 423 px
Center intersection. Fully visible across all smartphones, tablets, computers, and TVs.
Why YouTube Re-Compresses Every Banner Upload
YouTube automatically compresses every uploaded banner to approximately 134 KB on desktop viewports, and even smaller packages for mobile screens. This automatic re-compression cannot be avoided or bypassed by any export setting or file format.
Because YouTube's compression pipeline optimizes for worldwide bandwidth rather than graphical fidelity, aggressive re-encoding can soften delicate gradients and fine text. Our tools provide an approximate preview of this re-encode step so you can test contrast and readability before uploading to your live channel.
