How to Use This Tool
YouTube allows 100 characters in a title and almost never shows you all of them. The feed cuts at roughly 38, mobile search at about 50, the suggested sidebar around 60. Since the overwhelming majority of impressions happen in the feed, the practical limit is the shortest one — and titles are routinely written against the 100 that nobody sees.
Using the previews
Type your title and four previews update live, each rendering the truncation for that surface. The greyed-out portion is what gets replaced by an ellipsis. If your hook, your keyword or your number lands in the grey, it is invisible to most of the people deciding whether to click.
Enter your target keyword in the box and the tool reports its character position and whether it survives each cut. Keyword position is not a ranking factor in the way it once was, but it is a comprehension factor: someone scanning a feed reads the first few words and moves on.
The warnings, and what they mean
- Over 60 characters — not an error, but everything past 60 is decoration on most surfaces. Make sure the essential part is before it.
- Two or more ALL-CAPS words — capitals do attract attention in a feed, and they also read as clickbait. One emphasised word is a device; three is a warning sign to a viewer.
- Emoji at the start — they survive truncation and add colour, but they also consume characters from the most valuable position. Put them at the end if you want them.
- Filler opening — titles beginning "In this video", "Watch as I" or "Today we are" spend the first 20 characters saying nothing. The tool flags the common ones.
What this tool deliberately does not do
It cannot tell you whether your title will perform. Click-through rate depends on the thumbnail, the channel, the topic and the audience far more than on character count. What it can do is guarantee that the part you care about is actually visible, which is a necessary condition rather than a sufficient one.
It also cannot fetch your video's real impressions or CTR — that needs the YouTube Data API and a signed-in account. Everything here is measured against the title text you type, in your browser, with nothing transmitted.
