YouTube Title Length Checker

The title and the thumbnail are one unit

A viewer never reads a title on its own. They see a picture and a line of text together, decide in about a third of a second, and move on. Which means the parts of the title that get truncated are, for most viewers, the parts that never existed.

This tool shows you exactly where the cut falls. The mock-ups use the real rendered widths and the same two-line clamp YouTube applies, so the ellipsis you see here lands where a viewer's does.

How long should a YouTube title be?

The hard limit is 100 characters — YouTube refuses anything longer. The practical limit is nearer 60. Past that you keep the full text in search results but pick up an ellipsis in the up-next sidebar and on mobile, which is where most impressions come from. Around 40 to 60 characters is the range that both fits and gives search something to work with.

Front-load the hook

Whatever happens to the end of your title, the first 40 characters always survive. That is where the specific, curiosity-creating part belongs — the number, the claim, the twist. A title whose payoff sits at character 78 is a title most people never see the point of.

The checks, and what they are worth

• Keyword presence and position. The phrase people search for should be in the title, phrased the way a human would say it. Earlier is better, but never at the cost of it reading like a robot wrote it.
• Capitals. One capitalised word draws the eye. Four reads as spam, to viewers and to YouTube's own creator guidance.
• Numbers. Not a rule, but a specific figure consistently beats a vague claim. "Three things" is weaker than "3 things I got wrong".
• Emoji. One adds colour. Three or more looks like a channel trying too hard, and none of them help you rank.
• Repeated words. Saying the keyword twice does not double anything. It just costs you characters.

The score is a rough summary, not a verdict — every check is weighted the same because none of them is individually decisive. Treat a low score as a list of things to look at, not a reason to rewrite a title you already like.
