# theme.json and block width settings

 * Hello,
 * Previously using Gutenberg to build out pages I had the option to set the width
   from within the block, wide-width and full-width.
 * Upon starting from scratch with a theme.json based FSE theme, I cannot figure
   out how to get these settings re-enabled.
 * I have tracked it down to the “layouts” portion of themes.json, but it seems 
   to be incorrect.
 * Can anyone help point me in the right direction? My google-fu is failing me.

 * Hi there,
    You could try adding the following code under settings:
 *     ```
       "layout": {
       	"contentSize": "840px",
       	"wideSize": "1100px"
       }
       ```
   
 * You can change the sizes to fit your needs.
    Hope this helps -Jamie
