Creating a thumbnail? Here are the technical specs you must stick to for the best results:

The Perfect Dimensions

The ideal size for a YouTube thumbnail is 1280 x 720 pixels. This has a 16:9 aspect ratio, which matches the video player perfectly.

Technical Limits

• Minimum Width: 640 pixels.
• Max File Size: 2MB.
• File Formats: JPG, GIF, BMP, or PNG.

While you can upload larger images, YouTube will compress them. It's often better to export your design at the target resolution to control how it looks.
