I keep uploading banners to my channel but parts always get cropped on mobile. Anyone knows the updated size for 2025 that works properly on all devices?
I had the same problem until I checked the proper youtube channel banner size 2025 (https://propellerads.com/blog/adv-youtube-banner-size/) which is 2560×1440 px. The key detail is the 1546×423 px safe area in the center — that's the only part visible everywhere. After focusing my design on that area, the banner started looking clean across all devices.
