How can I change the number of projects from the portfolio archive?

First of all, you should know that each projects’ archive has its own style and structure. With other words, it means that a different number of projects listed there will impact the overall look-and-feel of your archive.

However, there’s a simple trick to change this particular number and display just as many projects as you want. To do so, please follow these steps: Go to Settings → Writing → Your Custom Content Types → Portfolio Projects, and change the value on this field.

Once you enter a different data, you will get the results you aimed for.
