Want to have my text in a single column but using a full width template? HELP?!

Good evening you coding legends,

This is my site… https://bryanlarkin.me/

Please could you tell me how I can have my text centered as a column so it doesn’t spread the full width?

I am using a full width template plugin to get rid of the sidebar, but i would still like my text easily readable down a centered paragraph in the middle if?

Is there any code that will do this?

My aim is something like this… https://kayspiegel.com/

I would like a similar setup to my content please

Thanks for any help.

Bryan
