@webmasterfocom You can not choose the number of article to display in a category. The number of articles shown on a category page is usually controlled by WordPress’s Posts per page setting.
Change the number of articles displayed
- Go to Dashboard → Settings → Reading
- Find “Blog pages show at most”
- Enter the number of posts you want to display (e.g., 10, 12, 20)
- Click Save Changes
If you’re referring to a specific number of article to display in a category than it needs code customization and you need to hire a developer.
Thank you!
