How it works
- 01
Type your title
The three previews update as you type, so you see the truncation point arrive.
- 02
Add a thumbnail
Upload a file or paste a YouTube link to pull an existing one. Uploads never leave your browser.
- 03
Read the narrowest one
If the title survives the suggested sidebar, it survives everywhere.
What people use it for
Choosing between two titles
Both look fine in a text field. Only one of them still makes sense after truncation.
Checking a long title
Long titles are not automatically bad — but you need to know which words get cut.
Pairing title and thumbnail
They are read together in half a second. Seeing them side by side catches redundancy.
Frequently asked questions
Where does YouTube cut off a title?+
It depends on the surface, not on a single number. The suggested sidebar is the narrowest and cuts earliest; search results give the most room. Around 60 characters is the practical ceiling if you want the whole title to survive everywhere — which is why this tool shows all three at once.
Do my uploads get sent anywhere?+
No. The image is read locally through a browser object URL and never leaves your device. Nothing is uploaded, stored or logged — which is also why there is no account and no limit.
Is this exactly what YouTube looks like?+
The widths and line counts match YouTube's desktop layouts closely, but YouTube adjusts them by screen size and tests variants continuously. Treat it as an accurate approximation, not a pixel-perfect mirror.
What about mobile?+
Mobile is narrower still and cuts titles sooner. The suggested sidebar preview here is a good proxy for it — a title that works there works on a phone.
Should I write for the shortest surface?+
Not necessarily. If your traffic comes mostly from search, a longer title that reads well there is fine. Check where your views actually come from in YouTube Studio before optimising for the wrong one.
Does the channel name affect anything?+
It occupies a line under the title on every surface, which changes how the block reads as a whole. It is there so the preview matches what a viewer actually scans.
