How does the truncation preview work?

It renders your title inside the same layout YouTube uses on each surface — the same font size, line count, and container width — so it clips exactly where the real UI clips. There is no invented character-count rule; the cutoff is genuinely about pixel width, and every character is a different width.

Why does the same title truncate differently on mobile, desktop, and Shorts?

Each surface gives titles a different amount of room. Mobile search results get a wider two-line title, the desktop suggested-videos sidebar is narrower, and the Shorts feed has the least space of the three because the like, comment, and share column eats into the width.

Why not just show a character limit?

YouTube caps the title field at 100 characters, but that number is not what gets you truncated in the feed. A title full of narrow letters like i and l fits more than one full of wide letters like W and M, so two 60-character titles can truncate completely differently. Layout, not character count, is the honest answer.

Is my title sent anywhere?

No. It renders entirely in your browser and is never sent to a server.

Real layout, real line limits — nothing is uploaded, and the title never leaves your device.

You write a title for the words. YouTube decides how many of those words anyone sees, and that decision changes every time it renders your video: wider on a mobile search result, narrower in the desktop suggested-videos sidebar, and narrowest of all inside the Shorts feed, where the like and comment column eats into the space. A title that reads perfectly in the upload form can get cut mid-word everywhere else.

This preview clips your title the same way — real layout, real line limits, real container widths — instead of guessing at a character count. Front-load the part that earns the click. If the same three or four words survive every surface, that is the part doing the work; if the punch line only shows up on desktop, most viewers on mobile and Shorts never see it at all.
