WP_Query default number of posts

Is that true that WP_Query by default returns 10 posts? I have more than 10 posts and didn't set the post_count variable and it returned 10 posts. Then I set post_count to 1000 and it returned all posts (Now I have 27 posts for test purposes). Then I read some documentation and learned from there that I can set post_count=-1 to return all posts. I tried and it worked. But I couldn't find an explanation if it's fine开发者_开发知识库 that it returns 10 posts by default. Thanks.

Yes, the default is 10 posts. You should have a look at the documentation for The Loop. That will help you get a better understanding of how this works.

Yes. The default number of posts is 10.

The easiest way to change this is in Settings after logging in Wordpress administrator.

You will see: Maximum number of posts to show in this site: 10

Change it !! And the maximun numbers of feeds if you want.
