Images on my blog are appearing small

I need help figuring out why the images on my blog started appearing very small regardless of resizing them in the wordpress editor.

I run a theme called divi and have updated my wordpress to the latest version, I use the default editor for blog posts and that seems to be where the issues lie.

I have tried changing the sizes in the html editor and deactivated some plugins, but that didnt work so I’m not sure where the problem lies.
