A compelling thumbnail is crucial in capturing viewers' attention and encouraging clicks on your video. Follow these guidelines to ensure your thumbnail stands out and meets the necessary requirements.
1. Uploading Your Thumbnail
To upload a custom thumbnail, click on the 'Upload file' button. Choose an image that represents your video content effectively and resonates with your target audience.
2. Ensuring Correct Dimensions
For the best results, make sure your thumbnail meets the following dimension requirements:
Aspect Ratio: The image should have an aspect ratio of 16:9.
Dimensions: The ideal size is 1280x720 pixels. However, the dimensions can be scaled down proportionally, as long as the width is at least 640 pixels and the height is at least 360 pixels.
These dimensions ensure that your thumbnail displays correctly on all platforms, enhancing its effectiveness in attracting viewers.
3. Why Thumbnail Dimensions Matter
Using the correct dimensions and aspect ratio guarantees that your thumbnail looks professional and is fully optimized for YouTube. Incorrectly sized thumbnails may appear distorted or be rejected during the upload process.
