Custom Post Type – How Many?

I don’t think there’s any limit.

Sweet as thanks! Would having a few cause any site performance drop offs you think?

I don’t think so.

Not that I’ve been able to see. A few hundred, MAYBE, but that might be a question for Otto in regards to permalink handling, more than anything else.

(per this https://ottopress.com/2010/category-in-permalinks-considered-harmful/ article)

Registering a post type with the rewrite flag adds between 1 and 5 rules to the permalink ruleset, depending on the options chosen. You’d have to have an awful lot of post types before it became a problem.

In contrast, the problem I talk about on the link above will make Pages add 11 rules each. Much easier to get quickly into trouble that way.

Note that if you register a post type with rewrite=false, then it doesn’t add any rules.

Thank you, Otto! ??

And now we know!
