Wysiwyg editor height is too tall

  • Hello!

    I would like to set default height of wyiswyg editor, it’s too tall.

    I want to set the height to e.g. “3 rows” for some of the editors such as contact information etc, that only need couple of rows.

    Thank you.

  • Hi @jari-pennanen

    Thanks for the post.

    It is possible to modify the dimensions of the WYSIWYG editor by hooking into the acf/input/admin_head action and passing some new styles.

    Please have a look at this example:

    add_action('acf/input/admin_head', 'lh_acf_admin_head'); 
    function lh_acf_admin_head() {
            <style type="text/css">
            .acf-field-5639b8dd6170b .acf-editor-wrap iframe {
                height: 150px !important;
                min-height: 150px;
            .acf-field-5639b8dd6170b .acf-editor-wrap .mce-fullscreen iframe{
                height: 700px !important;
                min-height: 700px;
  • Just another vote here to get this put into the admin, its really inconsistent that you can set the height of a textarea box in the admin and not the height of this field.

  • Hi @arkid77

    Could you please open a new ticket so your request can be passed directly to the plugin author? You can open a new ticket here: Also, please don’t forget to explain your request again.


  • I figured out a better method which allows the field to be enlarged so it’s not a static height. This just removes the inline styling so I can set a height via CSS without the need for !important. Hope this helps someone else!

    // Remove ACF inline styles for WYSIWYG
    function my_acf_input_admin_footer() { ?>
    	<script type="text/javascript">
    		(function($) {
    			acf.add_action('wysiwyg_tinymce_init', function( ed, id, mceInit, $field ){
    				$(".acf-field .acf-editor-wrap iframe").removeAttr("style");
    <?php }
    add_action('acf/input/admin_footer', 'my_acf_input_admin_footer');
  • Hi @inhouse ,
