How can I have a fixed width page in Confluence Server?

[Luciana Dias]

We were using cloud before and it was possible to change it by clicking on the arrows. Now that we have migrated to server, I cannot see the arrows to change to full width to fixed.

We just use the three column page layout, where the center column is the widest. It's not an ideal solution, but it makes things like blog posts much more readable.

If you mean the setting of the width in the editor, it does not exist in the current editor of the server version.In the side view you can reduce the left sidebar either to the icon size with the double arrow.
The size is set with the central element "collaps sidebar"
