The title tag is the way we declare the title of a page in HTML.

Many articles suggest keeping the title X number characters or X number of pixels long because Google only displays that much of the title in the Search Engine Results Page (SERP).

But should we limit the title to the number of characters or width displayed in Google search results?

I think in general your title tag length depends on how you intend your readers to use the title.

The title tag on SERPs should be long enough to maximize getting clicks.

A bookmark should be long enough to remind the user about the content of the page. If it is an information article (i.e. software documentation, tutorials), it’s ok to go really short (i.e. NUXT Templates) or long (i.e. How to generate SSH keys to connect to your Linux machine via the Console).

So basing the title length on how many characters Google displays on SERPs is OK, if people will find your page predominantly on Google and you are trying to get clicks.
