The title truncation preview, and why character counts lie
Truncation is measured in pixels, not characters. See where your title actually gets cut on three surfaces.

You write a title for the words. YouTube decides how many of those words anybody sees, and it makes that decision again on every surface your video appears on. The truncation preview shows you three of them at once, so you can see where the title actually gets cut before you lock it.
Character counts do not predict this
Nearly all title advice hands you a number: keep it under sixty, keep it under seventy. Those numbers are guesses at something that is not measured in characters at all.
This preview does not apply a character rule. It renders your title inside the same layout each surface uses, with the same font size, line count and container width, and lets it cut where the real interface cuts.
The three surfaces, and why they differ
| Surface | What constrains it |
|---|---|
| Mobile search | The most generous of the three, and where most people first meet a title |
| Desktop suggested | A narrow sidebar container, so it cuts noticeably sooner |
| Shorts feed | Narrowest of all. The like and comment column eats into the width |
A title that reads perfectly in the upload form can be cut mid-word on two of these. You rarely find out, because the surface you check on is almost always the one you happen to be sitting at.
What to actually do with it
Find the words that survive on all three. If the same three or four words are visible everywhere, those are the words doing the work, and everything after them is a bonus for whoever gets the full render.
Then check where the punch sits. A title whose reason to click only appears on desktop is a title most of your audience never finishes reading. Move that part to the front and let the setup trail off the end instead.
This is also the cheapest fix on a video that already went out. Rewriting a title so the promise lands in the first four words costs a minute and changes nothing else about the video.
The Shorts case is the one people miss
If you post Shorts at all, check there first. It is the harshest of the three and the one nobody previews, because Studio gives no hint that a whole column of interface is about to sit on top of your text.
Long titles on Shorts are close to pointless. The feed gives you a handful of words before it stops, and a viewer's thumb is already moving.
Nothing leaves your device
The title is rendered locally. Nothing is uploaded, there is no account, and you can paste an unannounced video title into it without it going anywhere.
