Frequently asked questions
What is the correct YouTube thumbnail size?+
YouTube recommends 1280×720 pixels (16:9 aspect ratio) for thumbnails. The minimum width is 640 pixels, but 1280×720 is the standard for HD displays.
What size should a YouTube channel banner be?+
The full banner is 2560×1440 pixels. However, YouTube only displays the central area on most devices. Keep your text and logo within a 1546×423 "safe zone" in the center.
Can I use this for YouTube Shorts?+
For Shorts, use the 9:16 vertical format (1080×1920). Add a custom size in the main resizer to generate that dimension.
