YouTube Title and Description Checker

A title and description checker tests your text against YouTube's rules before you upload, and previews how the video will look in search results on desktop and on a phone.

It counts characters against the 100-character title limit and the 5,000-character description limit, flags the < and > characters that YouTube refuses to save, and warns if the title and description together have more than 60 hashtags, which makes YouTube ignore all of them. The preview shows where your title gets cut off and how much of the description appears under it, which is often only the first line or two. You can type new text or load a published video's title and description to review it.

A title can be up to 100 characters and a description up to 5,000. YouTube won't save either if it contains the < or > characters, and it ignores all of a video's hashtags if there are more than 60.

Fitting the limit isn't the same as being seen. Search results and suggested videos cut titles off after about two lines, and only the opening of the description shows in search, so the words that matter most should come first.
