Why sixty characters, not a hundred
YouTube accepts a title up to 100 characters, and almost every generator writes to that number. The places a title is actually read — search results, suggested videos, the mobile home feed — cut it far earlier, usually around sixty characters and sometimes less depending on the device and the layout.
The practical consequence is that the last third of a long title is decoration. If your keyword, your hook or your number lives there, most viewers never see it. Front-loading is not a stylistic preference; it is the difference between a title that works on a phone and one that only works in your editor.
This is why each option here carries a bar rather than just a character count. A count tells you a number. The bar tells you whether the point survives the cut, which is the only version of the question that matters.
