How many custom controllers can we have per Visual Force page?

NagendraNagendra (Salesforce Developers) 
Hi Divakar,

Currently, there is no limit on the number of extensions you can have on a VF Controller. Of course, having too much of them would also affect the readability and maintainability of the code.

Note: You can use one extension attribute and You can mention many classes with comma separated.

For more information may I suggest you please check with below link from the community forums which might help you further with the above requirement. Hope this helps.

Kindly mark this as solved if it's resolved.

Thanks,
Nagendra

You can have the two controller functionality in one visualforce page by using standard controller and extension.
So in extension you can mention the name of multiple controller from which you want to access the functionality of these controller

I hope it helps you.
