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)
From CKEditor 5 version 22 the proposed programmatic solutions are not working. Here it is how I get the work done:
ClassicEditor.create( document.querySelector( '#editor' ) )
.then( editor => {
editor.ui.view.editable.element.style.height = '500px';
} )
.catch( error => {
console.error( error );
} );
.ck-editor__editable {min-height: 500px;}
