Custom/Editable width on posts

Hello

First of all I want to thank you for your work and time you spend on this theme, I really appreciate your work!

I got a short question about the content width of posts. My screenshots are usually too long to fit in the connect area without shrinking it to an unusable size.

It would be great if there was a way to change the width for the content area at least at a theme level, perfect would be on a post level.

I’m new to word press and creating content so maybe there is a better solution? But again, a editable width would be awesome!

Thanks in advance
Patrick
