Width of featured image on project post

Hi,

How do I make the featured image on a project 100% width across the post, same as a blog post.

Here is a link, at the moment it is centred link

Thanks
Stuart

Hello there,

The project page you shared contains smaller image; its original size is 480px x 320px. Before you upload the image, make sure its size is larger, minimum 810px wide.

Many thanks.

One other question, am I restricted on height for images used in projects or the blog

Thanks
