How do you create high-quality YouTube thumbnails?
The simplest and easiest hack to thumbnails is, first of all, zoom way up — make the thumbnail approximately 3 inches by maybe an inch and a half — and ask yourself, 'Can I still read all the text on that thumbnail?' If you can, your thumbnail's probably okay. Second, instead of putting your head on the left, put your head on the right. The reason why is because in the bottom right-hand corner of the YouTube thumbnail you have a little timestamp, and timestamp sizes depend on what the person is using to view the video. If they're looking on mobile as they scroll through their phone, the timestamp is basically a quarter of the size, meaning if you have any text down there it'll overlay it and cut it off. I've done hundreds, maybe thousands of videos where I've thought really deeply about thumbnails, and I've iterated little by little on every single one of these tests to determine that these are the two highest ROI parts to it. Aside from that, if you create high-quality content, then just have your face in the thumbnail. If you do not create high-quality content, then do not have your face in the thumbnail. The reason why is because people will recognize your face and they'll make a determination as to whether or not the video is worth clicking on entirely based off of your face. In my case, I create really high-quality content, so I put my face in the thumbnails. People really like the thumbnails that have my face in them far more than the ones that don't. Most of the thumbnail tests I run involve two with face, one without face, and probably about 90% of the time the ones with my face in it win.
