WordPress WSYWIG Admin editor is narrow

Google says it likely has something to do with some sort of styling from my custom theme. It looks like this.

it should be wider. Anyone got any ideas?

EDIT:
Never-mind, figured it out
wp-content/themes/fruitful/css/editor-style.css
Top of the css file, either delete or change max-width.

html .mceContentBody {
	font-size: 100%;
	max-width: 604px;
}
