YouTube Image Sizes: Thumbnail, Banner, Safe Area and 16:9 Tools
Use this hub to choose the right YouTube image guide before you export. Start with thumbnails for video uploads, banners for channel art, safe area checks for device crops, and the 16:9 calculator when you need a clean canvas size.

Choose the right YouTube image page
The fastest path is to match the asset type first. Thumbnail searches usually need size, ratio, file limit, and export checks. Banner searches usually need safe-area planning because one uploaded image is cropped differently across devices.

- Run the local checker or preview tool before publishing.
- Keep official source notes and last-checked dates in mind.
- Use related pages when the issue is cropping, blurry output, or text readability.
