How to change the width of the Content column in the admin UI?

System Information
  • Strapi Version: v4
  • Operating System: Llinux
  • Database: Postgres
  • Node Version: 18

I just want to modify the UI so that the content column is wider. At the moment it is set to a fixed width of 14.5rem, but the heading are wrapping and it looks a bit messy. I’d like to set it to 18rem.

I know I can override things in /src/admin/app.js using the config.theme onject but have no idea what I would override to set the width,

Here is how the Content column looks now:

The wrapping and spacing isn’t great

Any assistance with this would be great!

Ideally I can override the width to 18rem so it look like this:
