Struggling with banner display — what’s the correct YouTube size for 2025?

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 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.
