YouTube thumbnails are fundamental to the success of any video, directly influencing click-through rates (CTR) and first impressions of viewers. Using the correct size and resolution prevents distortions, quality loss, and ensures your thumbnail stands out on all devices. In this comprehensive guide, you'll learn everything about official YouTube thumbnail sizes and how to optimize them for maximum impact.
Official YouTube Thumbnail Sizes
YouTube establishes specific guidelines for thumbnail sizes, ensuring compatibility and quality across all platforms. Following these official recommendations is essential to avoid upload issues and guarantee the best possible visual experience.

YouTube Thumbnail Guidelines You Should Follow
