YouTube Thumbnail Size
A YouTube thumbnail is 1280 × 720 px at a 16:9 aspect ratio. That is the upload size; YouTube then serves it as small as 168 × 94 px in sidebar recommendations. The 640 px minimum width is a hard requirement — anything narrower is rejected. Design for the smallest render, not the largest: if the thumbnail is unreadable at 210 px wide, it will not earn the click.

Design Tips
- →Design at 1280 × 720 px but preview at 210 × 118 px — that is the actual size in the mobile home feed, where most impressions happen. Faces, three or four words of text, and one focal point survive that downscale; anything more does not.
- →The duration stamp sits in the bottom-right corner and the progress bar covers the bottom edge on watched videos. Keep the lower-right eighth of the frame free of text.
- →Stay under 2 MB. Export as JPG at 85–90% quality for photographic thumbnails, or PNG when the design is flat colour and type — PNG holds crisp edges on text that JPG smears.
- →Text should occupy at least 25% of the frame height to stay legible at sidebar size. A 72 pt headline at 1280 × 720 renders around 12 px in a sidebar recommendation.

What size thumbnail for YouTube?+
1280 × 720 pixels at a 16:9 aspect ratio. The minimum accepted width is 640 px and the file must be under 2 MB. Accepted formats are JPG, PNG, GIF, and WebP. Upload at 1280 × 720 even though YouTube displays thumbnails much smaller — the higher-resolution source downscales cleanly across every device.
What is the YouTube thumbnail size in pixels?+
1280 × 720 px. This is YouTube's recommended custom thumbnail resolution and matches the 16:9 ratio of the video player. YouTube generates smaller derivatives automatically: 480 × 360 px for medium, 320 × 180 px for the mobile feed, and 168 × 94 px for sidebar recommendations.
Do Shorts use the same thumbnail size as regular videos?+
No. Regular videos use a 1280 × 720 px horizontal thumbnail; Shorts use the vertical 1080 × 1920 px frame of the video itself. Uploading a 16:9 thumbnail for a Short means YouTube centre-crops it to vertical and usually cuts off both sides.
Why is my YouTube thumbnail blurry?+
Three usual causes: the source was below 1280 × 720 and got upscaled; the file was compressed under the 2 MB limit too aggressively; or fine text was exported as JPG rather than PNG. Upload at exactly 1280 × 720 px, keep JPG quality at 85% or higher, and use PNG when the design is text-heavy.
Can I change a YouTube thumbnail after publishing?+
Yes, at any time and as often as you like. Replacing a thumbnail does not reset the video's watch history or ranking. Testing a new thumbnail on an underperforming video is one of the few changes that can revive an old upload — YouTube also has a built-in A/B test for up to three thumbnails.
