In CKEditor 4 to change the editor height there was a configuration option: config.height.
How do I change the height of CKEditor 5? (the Classic Editor)
In the case of ReactJS.
{ // You can store the "editor" and use when it is needed. // console.log("Editor is ready to use!", editor); editor.editing.view.change(writer => { writer.setStyle( "height", "200px", editor.editing.view.document.getRoot() ); }); }} />
