Why correct dimensions matter on YouTube
YouTube thumbnail and channel art dimensions are strict. An incorrectly sized thumbnail appears blurry or cropped in search results and suggested video panels.
YouTube image dimensions reference
Thumbnail: 1280 × 720 px — Channel Art: 2560 × 1440 px — Profile Photo: 800 × 800 px — End Screen: 1920 × 1080 px. These are the current recommended sizes. Platform requirements occasionally change, so check the official YouTube help centre if you notice unexpected cropping after uploading.
Aspect ratio lock
When the lock icon is enabled, changing the width automatically updates the height proportionally (and vice versa). For platform presets the lock is disabled automatically since the preset dimensions have their own fixed ratio. Re-enable the lock if you need to scale uniformly from your own starting size.
Output format
The download is saved as a PNG, which is lossless and accepted everywhere. If you need a smaller JPEG for faster upload, use the Convert PNG to JPEG tool after resizing.
