YouTube Thumbnail Size
The correct YouTube thumbnail size — and a tool to resize your image to fit.
A YouTube thumbnail should be 1280×720 pixels — a 16:9 ratio — with a minimum width of 640px. A correctly-sized thumbnail looks sharp everywhere it appears, from search to the watch page.
Resize your image to 1280×720 here (already selected) and download it ready to upload. It runs in your browser, so nothing is uploaded.
