So everyone started updating their description to provide more information about the website to rank well in SERP. But in current days, the Search Snippets length were looking shorten. Also regarding this, there was a question raised by a Search Geek, and Danny Sullivan answered it through a tweet as mentioned below.
Our search snippets are now shorter on average than in recent weeks, though slightly longer than before a change we made last December. There is no fixed length for snippets. Length varies based on what our systems deem to be most useful.
