New Editor default text size ruins pages when converted

Rob Brooks November 12, 2025

When converting pages to the new editor the text size increases which destroys current tables and formatting.

Can this be edited as a default. ?

Hi @Rob Brooks ,

This will require a little bit manual work. It's not a bug but a design shift for better responsiveness. Unfortunately, in Standard plan, there's no global "default text size" setting to edit, it's a fixed system. This won't prevent migration changes but it might fix the post-conversion :) You can use CSS to override it:

1. Space settings > Look and Feel > Stylesheet > Edit.

2. Add CSS to normalize the font size:

body, p, .wiki-content {
  font-size: 14px !important; 
  line-height: 1.4 !important;
}
table.confluenceTable td, table.confluenceTable th {
  font-size: inherit !important; 
  padding: 8px !important; 
}

3. Then choose "Save". 

For consistency, manually convert pages (copy-paste content to new page in new editor). 

Hope everything works out for you. 

Best, 

Peter
