How to make a YouTube thumbnail people actually click

Coverage

Made for anyone whose video is done and who needs its cover picture to tell the truth about the video and stay readable at feed size. Five steps: pick one promise, make one subject with few words, shrink it and check it, export and upload, then test and read the result with YouTube's own A/B test. A small script measures size, shape, contrast and clutter, builds a preview on light and dark backgrounds and writes an upload-ready JPEG. Honest limit: YouTube Studio was not run by the author, the design advice comes from vendor blogs, and the script was tried only on invented pictures.

Example

On a drawn test picture at 3840 by 2160 the script gave no warnings; the same picture at 1000 pixels wide warned that a test would show every version at 480p, and at 600 pixels wide it failed the 640 minimum. A picture with its word moved into the lower-right corner was flagged, and a 24 MB noise picture became a 1280 by 720 JPEG under 2 MB.

Useful starting points

• Write the promise in one sentence before you open any design tool.
• Look at the small preview on the dark and the light background before you export.
• Test an older video first and change only one thing between versions.
