FAQs
What is a YouTube banner size?
2560×1440 is the full canvas; keep important art in the centre safe area. Use the aspect ratio calculator if you only know one side.
Will enlarging look sharp?
Upscaling cannot add real detail. Start from a larger source when you can.
Is the image uploaded?
No. Resize uses a canvas in this tab.
