What is the word limit for a post?

How many words can we write in a main post? any idea?🤓

Around 5000- 6000 (not sure of exact number) reason being I attempted posting something which was 13000 however had to cut it down in 3 posts.

First post I'd added was over 6000 however got the message saying it's reached it's limit.

So cut it down over 5000 and it worked.
