Latest news - number of posts on front page

I would like to show only three posts at any one time on the home page. Could you please help with reducing this number?

Also what is the correct size for the featured Images?

Hello,

  1. It looks like you already have three posts in latest news widget on your home page.

  2. You can use 830px wide images or larger.

Kind Regards, Roman.

I have more posts. When I posted them, they appeared below the first.
However, this has been taken care of by the previous adjustment to the projects.
Thank you.

You are welcome!

Please feel free to ask any other questions that you might have in future.

Kind Regards, Roman.
