Check your title, description, and tags against YouTube's actual character limits, with a search-truncation warning for long titles.
The Title & Description Checker validates a video's title, description, and tags against YouTube's real character limits before you publish. It's built for creators who want to avoid silently truncated titles or dropped tags, channel managers reviewing metadata before scheduling a video, and anyone who's ever wondered exactly how long a YouTube title or description is allowed to be. As you type, live counters and progress bars track your usage against each limit — 100 characters for titles, 5,000 for descriptions, and 500 combined for tags — with a clear warning once a field goes over. It also flags titles approaching the point where search results and suggested-video thumbnails tend to truncate them with an ellipsis, even before hitting YouTube's hard 100-character cap.
Titles: 100 characters. Descriptions: 5,000 characters. Tags: 500 characters combined, including commas — YouTube silently drops anything past these limits.
Search results and suggested-video thumbnails typically truncate titles around 60–70 characters — staying under that keeps your full title visible without a "..." cutoff.
YouTube has said tags play a minor role compared to title, description, and thumbnail — mainly helpful for correcting common misspellings of your main keyword.
All your tags combined, including the commas separating them — not each tag individually. The tool shows both your total character count and how many individual tags that adds up to.
No — it checks whatever you type or paste against YouTube's known, publicly documented limits. It doesn't connect to your channel or verify a video already published.
Yes — this youtube title length checker and youtube character limit checker shows a live youtube title character counter as you type, so you can check youtube title length before publishing.
Yes — description length is checked against YouTube's 5,000-character limit using the same live counter approach as the title field.
