What is the maximum size limit of varchar data type in sqlite?

I'm new to sqlite. I want to know the maximum size limit of varchar data type in sqlite?

can anybody suggest me some information related to this? I searched on sqlite.org site and they give the answer as:

Q. What is the maximum size of a VARCHAR in SQLite?

A. SQLite does not enforce the length of a VARCHAR. You can declare a VARCHAR(10) and SQLite will be happy to let you put 500 characters in it. And it will keep all 500 characters intact - it never truncates.

but I want to know the exact max size limit of varchar datatype in sqlite.
