Why is the text content small?

Hello, I’m new to Discourse and I’m trying to get to know the software, when I enter the content of the article, the text part is small and there is a space on the side, I wonder why there is that space?

I want it to be wider when they enter the text reading how can I expand the text part?

I marked it in the screenshot I want it to be full page how can I make it full page.

@EchoBilisim you can try this theme component… try setting it to 1400px (it defaults to 1110px)

Thank you very much

As to why the topic content is width limited at all – it’s to allow for easier reading with shorter line lengths. I recommend using Ctrl + for people who want it to fill their whole screen.
