The narrow width of the content in blog posts is correct. It is not meant to be full-width, as the ideal width to make passages of text more readable is approximately 70 characters per line.
However if you do want to make post content full-width there are a couple of different ways to do this:
Option 1 – some blocks can be set to full-width such as Group, Image, Cover, Columns, so to make some paragraphs full-width you can add a Group block, set it to full-width and add your Paragraph blocks inside the full-width Group block.
Option 2 – make all blocks in a post full-width. To do this navigate to Appearance > Editor and select the Single template (this is the template that displays single posts) to edit.
In the Single template, first select the primary Group block that contains the Post Content block and in the Layout settings in the right sidebar turn on the “Inner blocks use content width” option.
Next select the Post Content block and the alignment options will now be available so select “Full width” and save the template.
Thanks @uxl! Option 1 worked but couldn’t get option 2 to work. I can get by with option 1 though.
Thank you for the update @joelrtod
We were thinking of retiring this theme as it didn’t seem to be much used, but we may take another look at this as the core WordPress block editor has had some significant changes since this theme was first released, and it looks like the theme has fallen behind.
